Chile – Rebellious State
To many people Chile sounds like quite an exotic place – and in a number of ways this is true! It is situated in the very west of South America and unlike any other country in the world it is more or less a mere strip of land; it reaches about 4,300 km from north to south but is less than 200 km wide on average. It is bordered by the Pacific in the west and the Andes in the east. The logical conclusion is that Chile must comprise all types of climate and landscape, from coastal to high mountain regions.
In Northern Chile you will find summits with over 6000 m, many of them of volcanic origin. If you move towards the coast you'll end up in the mighty and quite famous Atacama Desert. It is one of the driest regions of the earth with rainfalls only once every couple of years. For a long time in the past it was famous for its resources of saltpeter ("Chile saltpeter"!), a chemical needed for the production of black powder, explosives and fertilizer. Today it is its vast and easily accessible resources of copper that people are after. And the dryness has another advantage: The air is very clear and clam thus making this area a perfect place for oberservatories – in fact, some of the largest telescopes of the world are to be found in the Chilean mountains.
Okay, let's move further down to the south, what do we have here? The climate is more or less Mediterranean, agriculture works out nicely and therefore it is no surprise most of the 16 million Chilean people live here. Don't forget Chile isn't wide! So all cities and settlements that are not situated directly at the coast are likely to be surrounded by mountains – the capital Santiago with over 5 million inhabitants is no exception.
There aren't many people living in the harsh South – lots of rain, storms, etc. and many islands at the coast. The southernmost point of the continent is the notorious, infamous Cape Horn. Prior to the opening of the Panama Canal all ships had to sail through these Arctic waters. By the way, Chile claims a good portion of Antarctica!
The political history of the country is very diverse; the most recent and hopefully last cruel chapter ended just 1990 with the retirement of long-term dictator Augusto Pinochet. Right now the country's economy grows at fast pace, partly due to the high copper price on the world market. Let's hope things continue this way!
For all those of you who have followed this blog regularly it is clear that Chile, too, must have been one of the many Spanish colonies, although for a number of reasons – like the difficult terrain especially in the country's South – there were countless wars over time. Official language is Spanish, but the pronunciation is so different from regular Spanish that some claim it's an own language.
Interesting! But what's there suitable for the World Scenic Flights? Well, the most obvious and stunning place certainly is the Easter Island (Rapa Nui) – its history is a thriller and features more than one collapse of its civilization. Known around the world are the mighty stone statues called moai. We'd certainly have liked to go there and come back with most incredible reports for you, but unfortunately the flight to this place was definitely not within our budget – it is a real killer.
Okay, then what's the next best solution? Given the short amount of time at our disposal we had to look for a good spot in the vicinity of Santiago. The capital is situated in a bowl of 50 km diameter surrounded by high mountains; this just adds to the usual smog problem of big cities since the wind cannot blow away part of the air pollution. Compared to other cities of the same size Santiago doesn't offer much. The skyline is humble, there are no real sights – most tours would take you to wine-growing or skiing areas in the Andes. No good for us, so what else do we have?
There are two hills in Santiago; the bigger one has been transformed into sort of a recreation area. A cable car of the Francisco/USA type takes you to a platform on top. Like at the Great Wall in China it was a nightmare to queue up with a 90-size helicopter and all our baggage. Even more so because police and our taxi driver had warned us there were many thieves who would just snatch your cameras or other luggage.
Once on top you have a good view over the city – but with lots of trees in the foreground and security guys all over the place. In lack of any better ideas we took a gondola from one part of the hill to the next one; before descending to the station we saw a serpentine road on the back side of the hill – there seemed to be a lot less trees, probably because it was the northern side on which the sun burns down all day long. Was it hot? Yep, something around 30 °C. Certainly better than freezing, but not comfortable either.
After a while we actually found the winding road and walked till we'd discovered a place with a good view over the town. It wasn't as good as downtown with at least a few skyscrapers in the financial district, but certainly there was something to it. Have a look at the picture! Quite cool and it reminds you of the Mojave Desert in California/USA, just much more populated.
The people were really nice. During the flight cars stopped, everybody got out and wanted to have a look at the helicopter. Some guys were so enthusiastic they wanted to have a go with it themselves; well, as everybody knows that'd have ended in a disaster so we just did another flight for them because we hadn't taken any still shots yet anyway.
The AFD panorama didn't work out well this time; too strong contrasts leaving you with a black picture in the shadow areas or with clearly overexposed shots in sunlit spots (remember you must not change any properties while shooting the complete panoramic scene including sky and ground!). We tried the whole range of possible camera settings, but no way; it was worse than at the Grand Canyon in Arizona.
But anyway, Chile was a great stop and the last one in South America. Next is Canada – Niagara Falls, what else!

Back to Mexico - and all problems
We have just returned to Mexico-City; we are more or less in transit since we'll continue to Canada tomorrow. South American airlines do not belong to the Star Alliance network so we had had to book them separately; from now on it's Star Alliance again.
Anyway, this time it was a NIGHTMARE to get into the country. We spent more than an hour discussing at the customs. Problems here, problems there ... and the funny thing nobody seemed to care about: We already HAVE been to Mexico a few days ago, and we do not intend to fly this time - it's just transit and we have plenty of documents proving this!
We finally made it ... which leaves us with the next problem: Our transport box is significantly damaged and needs to be overhauled (we haven't checked the heli yet)! Really, what is the problem with airlines in South America? Everybody has tons of baggage and it seems to be sort of a fun game between the baggage guys of who can smash things onto the ground the hardest. Or throw them right out of the cargo bay, who knows. The staff was friendly, no complaints - but that's not enough if you want to be a reputable airline offering good service!
We'll talk about the Chile adventure soon - just give us a little time to finish the latest ROTOR article, repair our stuff and maybe sleep for a change. We're looking forward to posting the next stories!
BTW, special thanks go to Marc Endres, not just for his spirited work regarding the German version of this blog, but also for providing us with a wealth of information regarding Canada.
Thanks also for the comment regarding the Panama Canal - we posted an answer right after it.
Then thanks a lot for the many emails - it is too much to handle at the moment; we respond to all incoming mail, but it may take a while! The questions are often similar so it would be really better to leave them as a comment!!
To those of you who have asked about new HeliGraphix releases via SKS Video Productions in the USA - Scott Stauffer is a great guy, and he will get back to you with details! Apart from this, please watch the HeliGraphix website!
That's it for now, hear you soon!

Welcome to Rio de Janeiro/BRAZIL!
We have to say that Rio de Janeiro is one of the most beautiful cities we have ever visited. A unique mixture of mountains, bays, beaches (Copacabana!) and the city itself with a lot of green environment hides its 12 million citizens perfectly well. And no, it is not the capital of Brazil even though that's what most people think! Instead, this is the much smaller city of Brasilia (2.2 million inhabitants). But don't panic if you, too, shouted out loud Rio was the capital. It used to be – for almost 200 years until 1960.
Prior to our visit we received many warnings; it is fact that Rio is one of the most dangerous places on the planet. It is no joke at all some thugs will kill you for a new pair of sneakers. My cousin's friend was murdered in Brazil some years ago when as a mere reflex she was trying to protect her backpack against theft. It's the same rules as everywhere: Avoid hot areas, behave normal and don't make yourself an obvious target by running around like a stupid tourist.
The Federal Republic of Brazil has a complex history and became independent from Portugal in 1825. Right, it wasn't Spain this time! As a matter of fact Spain and Portugal had a contract how South America would be divided between them once the terrain was conquered. Total population of Brazil today is about 190 million; this makes it effectively the fifth largest state of the world (same goes for its total area, although major parts are more or less inaccessible tropical rainforest).
It is a shame what Copa Airlines do with your baggage. Our specially designed helicopter transport box was wet and looked quite damaged when it came lying on the belt in the baggage claim area. This meant repair work was necessary; very nice, Portuguese-speaking Rio de Janeiro is the perfect place for finding a DIY store … What's more it increasingly turns out our schedule is very tight, making traveling exhausting. You never get the chance to feel at home anywhere. Once you start getting an overview of your surroundings it's already time to board the next plane. We barely find the time to wash our clothes or get a haircut every now and then.
Ah! The guys have to do more things than just rush from country to country, explore the environment, deal with authorities, film and take pictures, do AFD panoramas, write, write, write, transfer and process data, do backups, send them home, etc. – they have to eat, sleep and deal with everyday issues as well! How right you are!
"Rio de Janeiro" got its name form a Portuguese explorer – it means "River of January"; guess why! What famous landmarks do we find here? Well, there is the statue of Christ on top of the 700 m high Cocorvado mountain; it is 30 m high plus an 8 m tall base. Apart from strong winds, serious security and crowds of visitors there are two major problems associated with it. Firstly, if you want to see it from the front (for sure you will) rather than from its back then you have to stand on the visitor's platform which is just over 100 m long; bad angle! From the ground or the nearest other hill it is a mere speck in the sky. And then, there is still the second problem: Since we are on the southern hemisphere the sun rises in the east and moves over the north to the west where it finally goes down. Unfortunately this means that Christ is mostly lit from the side or even from the back – which would leave you with a black silhouette on the video!
Okay, what else do we have? All over Rio you will find granite rock of very distinct shape. One of them is world-famous, and not only since the showdown between James Bond and Jaws in Moonraker in 1979. It is the Sugar Loaf Mountain; no other "hill" (it's only 394 m! :-) ) has a shape as cool as this one. And now comes the best: It is situated on a peninsula which means you can film it from across the bay! Perfect lighting, a nice harbor panorama with houses and ships – what else could you wish for?!
When looking back these were the first truly relaxed flights of the whole WSF project. The only thing which spoilt the scene a little was the strong wind; I wanted to loop around the Sugar Loaf Mountain but had to do it flying with the wind. At full pitch the 90-size Three Dee MP XL-E (and this heli really has plenty of excess power!) barely made it back against the wind once it was in the loop. So on top I had to do sort of half a flip and then push it against the wind with full negative pitch. It looks a little funny in the video as there – of course – you don't see any trace of the wind.
We think that when the WSF video is out some of you will want to reread part of these lines. All the readers of this blog and of ROTOR magazine have a wide and really interesting background of why what was shot how. It is very cool to experience how something as big and of the nature of the WSF is created, isn't it?!
We were lucky with the weather – the day of our flying was the only one without rain and overcast skies. Nonetheless we shot a very cool AFD panorama the next day! Actually we found a heli pad and got permission to take the pictures from there. It is on top of a hill, high above the city and vis-à-vis of the Christ statue. Just 300 m away was another visitor's platform (that's where the picture on top was taken the day before); theoretically we could have flown from there as well. It's just that the full-size heli came in every 7 minutes to pick up new people, and if there is one thing you must never do, then it is to interfere with full-size aircraft. But like said before, the weather wasn't as good as the day before anyway and we saw plenty of armed security in the vicinity.
All in all, Rio de Janeiro was a cool stop – we'll be cherishing the memory of it and can only recommend it to you!

The Panama Canal Challenge
There is one special place along the Panama Canal where it gets so narrow that only one ship can pass at a time; it's called the Gaillard's Cut. We spent a long time trying to find it, without success. The public road ended in a city called Gamboa; but since the canal was hidden behind rainforest most of the time it was probably easy to miss that part. Darkness had fallen and we had no choice but to give up for the first of our two day's stay in Panama (in fact we had long found the Gaillard's Cut, but it looked too different from all the pictures we had seen!).
Gamboa is only accessible by crossing a one-way bridge; this means there is traffic lights at each end and you have to wait half an eternity until you get a go signal to cross the bridge. Bridges are often built over water, aren't they, and when you cannot kill yourself by jumping off, then there usually aren't any fences! Hmm …
We had a look at the surroundings and discovered a parking lot right next to the canal. Entrance prohibited! There was kind of a shed; the sign over the door read something like Canal Authority Electronics Department. If you crossed the tracks of the Panama Canal's own railway company you stood right next to the water – no fence! We couldn't see much in the dark but decided to return the next day and give it a try. None of us had a good feeling; all of this smelt like big trouble.
The next day it was raining cats and dogs. In the early afternoon we decided to drive to the place we'd found the evening before and to wait for a rain break. So we drove there and waited, and waited, and waited … Despite the camera problem (condensing air humidity, see last post) we had to activate the A/C from time to time in order to not drown inside the car because of the moisture. Really, it was so bad we felt like in a Turkish steam bath! There were times when the rain got lighter, but then it started to pour again.
We don't know how long we had to wait, but in the late afternoon the rain had finally become a drizzle. After a look into grey skies we were convinced it wouldn't get any better; either we pulled off the stunt now or never!
The original idea from months ago had been to find the Gaillard's Cut, position on top of the hill and wait for a cool ship. Today we were happy if it didn't rain, to say nothing of a ship! Like mentioned in the last post every vessel is accompanied by a patrol boat; in other words: If you wait for a ship the mission is over before it starts!
Of course we waited for a ship. :-) However, we let it pass so it wasn't too obvious for the guys on board that an aircraft was flying over the canal. In addition we kept the heli low over the water so it was even harder to spot against the dark backdrop. Very unfortunately we got another problem with the video camera and thus had to do a quick landing. By the time we could take off again a couple of minutes later the big freighter had become a little bit small in the distance.
The automatic mode of the camera did not work well and lead to more or less black silhouettes; we thus chose the image properties manually and took off again. After just three low passes over the canal the first patrol boat was approaching at full steam (you'll see it in the video!); most likely they'd been attracted by the first flights already. We continued to fly and once they were near I did a nice pirouette to greet them. :-)
Less than two minutes after take-off a patrol car rushed onto our parking lot honking like wild (certainly the boat crew had contacted them by radio). Time to land and to take one last deep breath; let's hear what the guys have to say …
A couple of minutes later we were free again. No more flying, but taking pictures obviously was okay. We prayed to God that our short film contained a usable sequence and we didn't have to leave with empty hands.
For the moment we thought it was best to wait for another ship (this takes about half an hour!) and to take at least stationary pictures, i.e. without the heli in the air. Finally, another freighter came, we positioned next to the canal, the camera clicked a couple of times – and hooray! – the patrol car was back!
It was not allowed to even stand next to the canal or the railway tracks. Difficult situation as we wanted to also do an AFD panorama. It hadn't been possible in Mexico (they'd probably have arrested us for trying that) and Panama was the only other country of the "region". So we prepared everything, positioned the tripod near the canal – and 'honk, honk!' our friends were back. To avoid an escalation of the situation we showed the WSF pictures and put all our stuff into the car ostentatiously. You need to be very diplomatic in such situations; causing trouble repeatedly leads to being arrested faster than one thinks!
We finally did manage to shoot an AFD panorama, but the light was not overly good; let's hope that IPACS/Ikarus will make use of it.
Somehow it is funny. In a number of countries they think the heli is a flying bomb and you are a terrorist; that's most dangerous because this way you may end up being shot. Some other times authorities are concerned about the safety of objects and people. Next is the class where they are convinced you are a spy and the heli carries a camera (the heli as a camera carrier is the first thought of nearly everybody, by the way); we had more than once problems with armed forces for exactly this reason. It is mostly in over-regulated Europe that you will need a number of special permissions to operate a remote-controlled aircraft in or near cities, monuments, etc. And finally there is sites like in Mexico where they don't care about the helicopter at all but where it is a matter of image rights. Really, it is strange and funny at the same time how the focus varies across the world!

The Green Hell of Panama
The Republic of Panama is a rather young country and has a total population of only 3.2 million. The pretty much most important source for foreign exchange is the Panama Canal. It connects the Pacific Ocean with the Caribbean Sea and thus the Atlantic Ocean; length of the passage is merely 80 km. It is the strategically most important canal in the world and is mainly used for trade between the East Coast of the USA, China and Japan since the circumnavigation of South America means an extra 15 - 20,000 km! Cost for the passage depends on the size of the ship and are typically 50 - 150,000 USD; the crossing takes about 10 hours.
The first plans for a canal had been made in the 16th century already, but it wasn't until 1881 that France actually started excavations, approved by Colombia (Panama did not yet exist at that time!). Why France? Well, it was a French company that had successfully built the Suez Canal linking the Mediterranean Sea with the Red Sea through Egyptian terrain. Inspired by this success they thought it was as simple to build a channel through a jungle as it had been to build one through a desert.
After many scandals the works ended in fiasco in 1889. An unbelievable number of 22,000 people had lost their lives in the green hell of Panama, mainly because of Malaria and Yellow Fever (at that time little was known about how these diseases spread). Only 1/6th of the canal had been completed by that time.
The remains of the canal were sold to the USA in 1902, but Colombia did not agree to the terms of the USA for continuing work on the project. So the history repeated itself, like so many times before and also till present day – the USA supported a revolution within the country, leading to the foundation and independence of Panama from Colombia in 1903. A few months later in 1904 a corridor around the projected canal became U.S. territory – "forever", so the contract.
The construction continued from 1906 to 1914; another 6,000 workers died. Since its official opening in 1920 the Panama Canal has caused repeated political tension between the USA and Panama; on 31st Dec. 1999 the canal was finally given to Panama.
In 2006 it has been decided to expand the current Panama Canal so it can be used by larger ships, the so-called Post-Panamax class. Works have begun this year and completion is scheduled for 2015.
When checking in for flights to South America you have to show your official vaccination card with proof of vaccination against Yellow Fever. The flight from Mexico to Panama is only four hours; at the Panama customs we ran into serious trouble with the helicopter. We're pretty sure it might have become the same nightmare as in Egypt if it hadn't been for our many, many pictures of the heli in front of monuments worldwide. We explained a lot and were finally allowed to enter the country. No need to say how happy we were when thinking back to the interrogations we had had to endure in Egypt; that really had been hell on earth, there is no other words for it.
The customs officials had told us that radio frequencies were a big issue in the Canal Zone and that for use of any radio equipment permission from the Canal Authority was necessary. We of course nodded but were sure that with robbe/Futaba's 2.4 GHz FASST system and the low output power of R/C transmitters there would be no problems whatsoever. We were right about that (no surprise), but little did we know about the loads of other problems associated with flights over the Panama Canal.
The climate in Panama is tropical which means one good shower a day and extremely high air humidity. Regardless of what you do, your clothes are wet all the time; very good, of course, when changing from air conditioned rooms and cars to the outdoors and back. It's a wonder if you don't catch a cold. Another problem in this context is that when taking your film/photo equipment or the heli and transmitter out of an air conditioned car the lense, display, etc. will immediately steam up. You can't take any pictures for up to half an hour until the equipment has reached ambient temperature! We solved the problem by using the A/C as little as possible; the price you pay is that you sweat like hell and feel eternally worn out after just one or two hours. If we'd closed our eyes we'd have fallen asleep in no time …
Talking about A/C: Our hotel room of course did have such a cooling system. Unfortunately, it was so loud that normal conversations across the room were a problem! Turning it off was no good as humidity (not the heat) would have killed us. So we had to put up with the noise – it felt like sleeping in the generator room of a power plant! The best way to deal with this situation was to use earplugs. Not a comfortable stay at all, but when booking hotels in 20 countries over the internet you cannot spend hours checking every last detail of every place.
Panama-City is the capital and quite a flashy city with a nice skyline – but better not scrape off the shiny surface! Apart from some major roads the infrastructure is not the best and driving is neither relaxing nor fun. Multi-lane roads often don't have any road markings, a number of one-way streets make navigation difficult and signs e.g. on the highway are mostly ONLY at exits; in other words, when you can read the sign it is usually too late to react and you can only continue on the current road. To make it extra hard they use an especially narrow type font so you don't get the chance to read the signs already from a distance (in the unlikely case you see them coming).
Did we talk about the torrential rains? It is so bad that parts of the streets are flooded – it pays to think twice before crossing such fords. Some of the cars are equipped with snorkels for exactly these situations. And the worst: There are some really, really deep potholes! The tricky thing is they are completely filled with water so it looks as if an ordinary puddle was coming. But it isn't! Instead it's a hole which can swallow "half" a car. To us it happened twice; the cars around you drive like wild and keep you busy by using their horns so that the pothole traps catch you by surprise. We tried to turn right when all of a sudden – WHUMPP! – a good portion of our front dived down into such a hole filled with water.
Okay, where is that canal?! In maps and satellite pictures you could see a small road following the course of the canal; we tried hard to find it, but after about five hours we had to realize that it was merely a support road and not open to the public. It may sound as unbelievable to you as it sounded to us, but the Panama Canal is one of the best-secured structures we have ever seen. There are high fences everywhere, usually with barbed wire on the top (and no, we didn't have a ladder at hand this time :-) ). The streets near the canal are patrolled by a number of security cars of the Canal Authority. Every big ship is accompanied by a tug boat plus one patrol boat. Between the ships a wealth of such fast canal patrol boats go back and forth. In other words: There is no reasonable way to get close to the canal! You think this cannot be true, but it is. You stretch your hand out over the water, they will come for you.
The reason for all the fences and stuff may be that the terrain used to be U.S. American property. Remember, the canal didn't belong to Panama until the year 2000! Now, are all the 80 km fenced in?! Good question, and the answer is: Probably not! BUT: That's not necessary anyway because the canal leads through tropical rainforest. This kind of forest is so dense it is totally impenetrable; hard to imagine, but even a huge tank wouldn't make it more than a few feet into the thicket. It's often swampland, too, and the home of a wealth of animals you don't want to meet; we saw the first big silver-grey snake cross the street while driving along some deserted roads. And then, even in the theoretical case you'd make it to the canal banks, how could you possibly lift off?! So 'Game Over' for the Panama Canal?

Mexico – Home of the Beetle
Greater Mexico-City counts more than 20 million people and is – maybe apart from Tokyo – the largest metropolis in the world. We were surprised that the airport is comparatively small, and after some discussion at the customs because of the helicopter we found it wasn't allowed to take the trolleys out into the arrival hall. Instead you had to pay somebody to take your luggage to the taxi; including our carry-on baggage we have a total of over 80 kg and thus not much of a choice. As pointed out in ROTOR 11/2007 and especially after the attempted express kidnapping in India we made sure to take a pre-paid and registered taxi to the hotel.
The ancient city of Teotihuacan in the state of Mexico is one of the most important archaeological sites of the country. In 1987 it was added to the list of … you know what! These guys … :-)
It is situated within reasonable distance of Mexico-City so we went there on a private tour. Our driver and guide Jose Luis was simply great; he spoke perfect English and had done all of his homework properly. In fact, Mexican tour guides have to study at university for three years and learn at least one foreign language. What's more, they have to attend additional courses every other year to keep themselves up to date; if they do not show up of fail the test they lose their license. That's the reason why these guys do not talk as much nonsense as many freelanced guides in other countries.
Anyway, the city of Teotihuacan was a political and religious center for many centuries. Most notable are its broad central "Avenue of the Dead" flanked by the world-famous Pyramid of the Sun and Pyramid of the Moon. The founders of the city are unknown till present day; fact is that work on the smaller buildings started about 200 BC while the large pyramid was completed around 100 AD.
The Pyramid of the Sun is the third largest pyramid of the world. Its height is 63 m, the base length an impressive 220 x 220 m; this accounts for a total weight of about 3 million tons! Unlike the Egyptian pyramids both the Sun and the Moon Pyramids were no tombs; instead, they were platforms for temples used during ritual ceremonies. They used to have a nice dark red color in former times.
Since the Pyramid of the Sun is not nearly as high as the Gizeh pyramids it made no sense to picture them from a greater distance, e.g. from the hills in the vicinity. Another advantage in Egypt was the missing vegetation; this made those pyramids look even bigger. And finally, the Egyptian buildings were surrounded by hills which allowed a perfect view.
Upon arrival at the archaeological site we bumped into big signs stating that photography was not allowed unless you paid a small fee. Not a problem, but professional photography had to be additionally authorized by the archaeological office. The term "professional" meant using non-miniature cameras or a tripod, not to mention a somewhat bigger video camera. So we obviously fell into the "professional" category and problems were preprogrammed.
We went straight to the boss of the pyramid site and explained the WSF project. We literally drowned him in a sea of pictures, showed our multi-language project description, our travel itinerary and other documents. It seemed he was most impressed with our visit to Gizeh/Egypt; those pictures (all WSF pictures!) are really priceless and maybe the best cover shots ROTOR magazine ever had. It's a pity you can't be on the cover all the time; the World Scenic Flights are without any doubt the largest project in the history of model sports and there is countless new photographs which should be in big print on a front cover rather than a line-up of smaller images somewhere in the middle of a magazine. Having said this, we know that being an editor is not an easy job and there are many different aspects that have to be taken into account when putting together an issue.
We finally got permission to take pictures from the ring road around the archaeological site. Like explained earlier the luxuriant vegetation as well as a high fence with barbed wire on top made it impossible to get a good view. From wherever you looked, it was the big fence, then trees, trees, trees and the tip of the pyramid in the distance. We therefore drove around the whole site and eventually stopped at a restaurant behind the moon pyramid; the owner was a really nice guy and we got access to the roof. Quite a good view … but not good enough as the position of the sun was bad, also there were some overhead power lines plus two big trees, and finally we could only see the rear side of the pyramid.
We continued driving back and forth; there had to be a suitable spot, only we hadn't found it yet. We got out of the car and walked up and down the fence. After a lengthy while we ended up in one spot where the trees almost formed an avenue towards the pyramid. Yes, this place seemed to work; if only the damn fence were out of the way! It was really high – how could you possibly film over it?!
We decided it was best to have lunch as an hour later the sun would be in a much better position. We ate some traditional Mexican food including cactus. Saskia liked it but it was not made for me. We hear Japanese researchers claim eating this kind of cactus raw is very healthy – the only problem being it then tastes several times worse than the cooked version! This is another indication that nature doesn't want us to grow really old; if it did, it wouldn't be that hard to lead a healthy life, would it?! ;-)
After lunch we returned to the designated spot. We had borrowed a ladder and a high chair to be able to look over that disturbing fence. :-) As you would expect the whole construction was quite shaky! Saskia was busy not to get hurt by the barbed wire while I was busy not to fall off the chair while piloting the heli. What made the flying even more interesting were some trees over the take-off/landing area; it wasn't that bad, still I had to be careful to cross the fence at an altitude as low as possible.
Flying at the other side of the fence was not a problem; robbe/Futaba's 2.4 GHz system performed flawlessly also under these conditions. The nasty thing for me was the uppermost wire of the fence which constantly obstructed my view of the helicopter. It was a problem to judge the distance to both the machine and the nearest cactus and tree. Making bigger movements while standing on a chair is not the most brilliant of ideas, so I simply tried to either fly in closer distance or to remain rather stationary between the trees. Because the size of the helicopter has to be in reasonable proportion to the backdrop (in this case the pyramid) you often don't have much of a choice but to fly in a way that it looks good in the picture. Man, the good old days at the flying field where you could just fly what, where and how you liked were really great …
We managed to do two quick flights of five minutes each. Right after the second landing security showed up from all directions – really, it looked like if we were under siege! Our tour guide was a big help negotiating with the people. We explained we did have permission, but unfortunately they couldn't reach the chief of the pyramid site on either of his phones. He had left the office around noon and thus nobody believed we'd really talked to him. All explanations of the WSF project were in vain; we had to leave our contact details and were told we could not use our photographic material unless approved by some central authority in Mexico-City. Most of the guys were quite reasonable but seemed a little bureaucratic; from our point of view things were made much more complicated than they actually were. We better spare you the details of these lengthy negotiations; we are glad our hard work wasn't confiscated right on the spot. At the moment we are still in contact with the guys to make a point of the outstanding nature of the WSF project and to find a good solution to create a win-win situation.
Meanwhile we have continued to Panama in Central America. We have long given up the idea of a day off to relax and just look around. Insanity never sleeps, and we are right in the middle of the next adventure. Stay tuned!

Mystery & myth: The Mayas and Aztecs – a living legend
Contrary to common belief, Mexico – or the United States of Mexico, to be more exact – is a North American country; only its very southern parts belong to Central America. It consists of 31 states and one Federal District which is more or less identical with Mexico City, the state capital. Total population is 110 million; this makes Mexico by far the largest Spanish-speaking country in the world.
The Spanish conquerors first arrived in 1519, defeated the original inhabitants and set up a colonial rule lasting as long as 300 years. What used to be the Spanish Empire's largest colony finally got back its independence in 1821. And now the interesting question: What was before the Spanish invasion?!
Today as much as in former times people are fascinated with the ancient cultures of the Mayas and the Aztecs. Partly this may be due to the practice of human sacrifice as featured in many Hollywood film productions. The reality is much more complex; fact is that human presence in this area could be proven to exist as long as 40,000 years! At this stage of the Paleolithic Age and for the next 30,000 years to come people were of course hunter-gatherers. Some 9,000 years ago corn was domesticated in this area, leading to an agricultural revolution; the consequence was the same as in other parts of the world: People began to settle and formed civilizations.
A wide variety of civilizations and tribes used to be present in Mesoamerica in the past 3,000 years. Best-known are the Olmecs, Mayas and Aztecs. The Mayas were the first to develop a comprehensive written language, they had a phenomenal understanding of mathematics and astronomy, and also they are known for quite monumental architecture. Their heyday began around 300 AD and continued more or less until the arrival of the Spanish. And now comes the most striking: The Mayas still do exist today! Much of the rural population of the Yucatan peninsula, in Guatemala and in Belize are Maya by descent; a variety of the different Mayan languages are still spoken there as primary language and are at least in Mexico protected by law.
The Aztecs came a lot later than the Mayas. A good definition of who or what actually were Aztecs is quite difficult; commonly the term refers to certain ethnic groups of central Mexico who spoke a language called Nahuatl. They came from the North (maybe even from today's Southwestern USA) and achieved military and thus political dominance over significant parts of Mesoamerica. Like the Mayas they, too, were a very advanced civilization and most active from the 14th throughout the 16th century. Their rule was abruptly ended by the Spanish invasion.
The above shot shows some authentic Aztec dancers – quite cool and they may have been more impressed by the helicopter than vice vesa. :-) BTW, the chief of the troupe (standing to my left) is Nahui-Martin Chavez – that's the exact same guy who with his team represented Mexico during the 2006 FIFA Football World Cup in Germany!
On this occasion they also demonstrated the Aztec version of an ancient ball game (the Mayas had called it "pok-ta-pok"). Two teams played against each other; the aim was to shoot a rubber ball through a small ring fixed to one of the side walls of the field in a certain height. Since in this version of the game it was only allowed to touch the ball with one's elbows and the ring's inner diameter was not much larger than the ball, it took a whole while until one of the teams succeeded. Sounds like a cool game? Not really. The captain of the losing team was beheaded right after the end of the contest (some people considered this a great honour at that time).
At the time of this writing we are still talking to Mexican authorities. We hope to get clearance and come up with a post regarding our flying action at Teotihuacan very soon.

The Grand Canyon Flights
The Grand Canyon certainly is one of the most impressive natural structures of this planet. It is situated in Northern Arizona and has an unbelievable length of 450 km, its width varying from 6 to 30 km. One distinguishes the higher North Rim, the South Rim and the Inner Canyon; the depth is up to 1.8 km and thus it is no wonder that on the way down through five different climatic zones both flora and fauna change significantly.
Natives already lived here some 3,000 years ago, but it wasn't until 1540 that a Spanish expedition (who else at that time!) first reached the South Rim – they were impressed and realized it was impossible to cross the canyon. So they left, and it took more than 300 years until the first serious explorers and cartographers came back to the area.
How did the Grand Canyon came to be? About 70 million years ago the Rocky Mountains were born and blocked the Colorado River which used to flow in south-eastern direction. So it changed its path in western direction, right across the newly formed Colorado Plateau. The rock there was comparatively loose and melted snow and ice from the Rockies let the Colorado grow into a mighty river; an unstoppable erosion process started, and here we are, 50 million years later, left breathless with such an incredible piece of nature.
Guess what – the UNESCO guys were also here! In 1979 the Grand Canyon was added to the list of world nature heritage. We really wonder when these guys will show up in our backyard at home …
After exchanging the main drive wheel of the Three Dee MP-XL I thought it was a good idea to do a quick test before flying it out over the Grand Canyon. Some guys who know me personally will smile now, but: With age comes wisdom …! ;-)
All kidding aside, the problem was that the whole area is densely covered with trees; except the roads and the parking lots in the Grand Canyon National Park there are no suitable spots for flying. We drove 25 miles through the park and finally found what appeared to be a former road into the woods. It was quite covered with trees, too, but at least reasonably firm soil so the heli wouldn't disappear in a cloud of dust during take-off and landing. I lifted off – nothing unusual. The gears were louder than normal but that's nothing uncommon with new gears. After 10 seconds I got bored and did a couple of precision flips between the trees. Everything seemed fine; very well then, back to the canyon!
It is until the very edge of the canyon that the terrain is completely covered with trees – one more step and the mighty canyon opens up before your eyes. Wow! – There is no words for this. One keeps looking in all possible directions, desperately trying to get this view under control; the sheer size and depth of the structure are just unbelievable. And now comes the problem …
The human eye and brain are a marvel that technology will never be able to hold a candle to. Capturing ultra-wide structures like the Grand Canyon is generally a big problem: The picture of any type of camera is limited! Granted, you could use special wide-angle lenses – but then the only way to create impressive scenes is to project them onto a large cinema screen. And even this leaves you with the danger of picturing just a plain "wallpaper" with not much of a depth perspective. Next issue when going for panoramic or full shots are the shadows. On the one hand they help you to add a third dimension to the scene – that's good! On the other hand this generates a high contrast situation – and that's very bad! Once again, other than the human eye film cameras – and especially digital video/photo cameras – have a very limited contrast range. Or in other words: If you don't want smaller details to break away in brighter spots the camera has to reduce the luminance of the picture. But this comes at a price: In the darker regions of the picture some objects will blend in with the background. So isn't it possible to brighten the picture just in the darker regions while not sacrificing details in overexposed spots? You'll guess the quick answer: No, you can't (you'd loose contrast!). It all boils down to increasing the dynamic range of the recording device, and like said before there is only so and so much that technology is capable of. Also think of videos of 3D aerobatic flying: When the sky is clouded and thus much light is reflected and the heli suddenly goes down and flies below the tree line it just disappears in the dark.
Okay, so we obviously have a problem – how can we fix it? Well, depending on what you actually want to express and to show with your pictures there is a number of things you can do. Even though it is very interesting to discuss such camera related problems, let's just focus on our very situation.
To add depth to still shots you will want to add "layers" to your picture. Find a bush for the foreground, then place the main object (person, heli, etc.) behind it, further in the background could be a distinct mountain, and only then follows the "wallpaper" far behind. Have a look at the shot below, it's quite three-dimensional.
Compared to still photography filming is always more difficult but at the same time greatly increases your possibilities. We wanted the viewer to first focus onto the helicopter and not to reveal the incredible backdrop at once. So at first the camera follows the heli with a close-up or at least a medium long shot while it is travelling towards us more or less along the edge of the canyon. At the point where it is closest the picture is almost fully open (heli still big!); the machine then dives down into the canyon, the camera zooming behind. It glides to the right and starts kind of a nose-in pie dish manoeuvre. The camera does not follow anymore but now opens the picture – wow! The vast size of the canyon becomes obvious while the heli gets smaller and smaller; the picture now slightly pans to follow the motion of the aircraft. When returning to the cameraman and pilot the picture again zooms in. Very impressive!
This simple kind of camera movement solves a couple of problems at the same time. First, the heli is presented to the viewer; his attraction is not torn between what the machine is doing and where it is flying. In addition, limiting the view quite effectively avoids bright and dark spots in the same picture; thus it is easy for the camera's automatic mode to light the scene correctly. Third, there's the "wow!" effect when the picture finally opens and the heli glides over the vast canyon structure.
The above sounds simple – and that's what it is in principle. However, good timing is required to create the "magical" scene we were looking for. It took us 2.5 battery packs to achieve an acceptable result. This means there was not much airtime left for still shots; so unfortunately we had to compromise a little on those.
Flying over the Grand Canyon was different from all other flights before. To get rid of the trees in the foreground and avoid disturbance by other visitors of the national park we had to climb down a couple of meters into the canyon. Not so easy with a helicopter, transmitter, battery packs, cameras and a tripod; one wrong step and you may end up on the rocks a kilometer beneath you! Same problem while flying and filming: You focus so much on the heli and the camera picture that the reference around you for keeping the balance is somehow missing. It feels somewhat like standing on top of a ladder while looking up into the sky; only the drop is a little longer … Now does this mean you have to stand directly at the edge?! Yes of course, how else could you fly and film down?! :-)
Crashing into a river, the sea or also into difficult terrain like at the Great Wall of China means the heli is completely lost – no way to get it back. But it was never more obvious then when flying over the Grand Canyon; the heli flies out and dives down until it is a mere speck in the sky, soundless, somehow lost in an unbelievably wide environment, gliding 1.5 km over the ground. I nearly got a heart attack when all of a sudden the tail swung around!
Emergency landing. Hell, what was that?! I had a very close look at the whole helicopter but couldn't find anything. After watching the situation on the video a couple of times I decided it was an RPM problem. Now how's that possible?
A couple of people have noticed (and asked by email) we sometimes use Kontronik's Power Jazz 63 V as electronic speed controller, and some other times the big Schulze ESC. The governor mode of Kontronik ESCs is legendary, and we use Kontronik equipment in pretty much most of our electric machines. However, when flying with throttle curves rather than flat lines (i.e. governor mode) we often prefer the Schulze controller. At the Grand Canyon site we wanted the heli to dive down into the depth as smoothly as possible. It looks best if you do not force it down in 3D mode or with constant RPM, but if you actually let it autorotate; in other words a throttle curve will work best in this case. Again this comes at a price: You cannot fly fast backward autos and/or do pirouettes forever. There is a point when the tail comes round and the machine "locks" into forward flight. That's what caught me a little by surprise, so … phew!
The 800 km drive back to LA was smoother than expected, and we had half a day left for visiting the Universal Studios; as cool as always. Personally I'm pretty sure that if I started my life again, I'd become a filmmaker. Isn't HeliGraphix moving more and more towards filming anyway? That's true; still there is a significant difference to Hollywood (at least up to now): HeliGraphix is NO special effects! Every second of film footage you see is REAL! Real people, real stunts, real adventures, real helicopters, real challenges, real crashes in a real world! Our life is no different from yours – that's what makes HeliGraphix so exciting, so tangible, so cool. And so insane … ;-)

Hollywood Heights
Personally, I've been to the USA quite a number of times and visited something between 10 and 15 states. Last time I was in the Los Angeles area is exactly 9 years back; the focus wasn't on R/C helicopters then, but the trip was lots of fun nonetheless. Actually Hellman and I (watch the famous "Tool Time" video on the HeliGraphix website in case you really don't know who this guy is!) had toured quite some part of the west coast and visited Las Vegas and the Grand Canyon. Those were the good old days … :-)
We arrived in L.A./California at 5 AM and had to wait 6 hours until we could collect our rental car; getting it earlier meant returning it earlier on the last day (which was no option for us) or paying an extra day. So we waited patiently at the LAX airport and were positively surprised that after sunrise it got significantly warmer than expected.
We finally got the car and – after a lengthy procedure of another 3 hours! – also got a GPS (that's what they call the sat navigation systems here). The first thing we did was to get us something to eat; right after this we drove to a supermarket parking lot and slept for two or three hours. We had tried to find some better location first, but we were so worn out that we just had to stop and get some rest immediately.
Los Angeles is an amazing city and certainly one of the largest in the world. While still driving to downtown we could already see the famous Hollywood sign in the hills. One of the original ideas was to find the sign and to fly there. Despite 4 to 6 freeway lanes for every direction (!) traffic was bad and by the time we got to the area it was already dark; the sun goes down around 5:30 PM. Unfortunately, the big white letters are not lit in the night, so the only thing left to do was to find a motel and sleep the sleep of the just.
The next morning we drove through Hollywood and some of the famous streets and took in Beverly Hills along the way. This is definitely a nice place to live, at least if you have the necessary pocket money to buy or rent one of the villas there. Many celebrities live here; however, you won't get to see anyone – they all hide behind big walls and the signs leave no doubt you aren't welcome. Quite understandable, though.
Since we are notoriously pressed for time we were quite happy that none of the famous guys came around the corner and spotted us. Imagine a similar scene like in the Australian hobby shop: We drive happily through Beverly Hills, and all of a sudden Bruce Willis jumps out of his driveway, dressed in pants and wearing a bloody shirt. He then limps to our car, rolls over the hood, stares at us through the windshield, frowns and shouts: 'Hey, aren't you those crazy German helicopter guys?!' Thank goodness he stayed at home so we didn't have to sign autographs and lost more time. ;-)
Finding the Hollywood sign was a nightmare. If you get closer you cannot see it anymore because buildings and trees obstruct your view. We went to nearby Griffith park, and while Saskia was busy to pull some thorns out of her hand after falling into a huge cactus I climbed two impressive hills to get an overview. BAD idea – the way up is always one thing, but the way down … Saskia decided to look away to not see me fall down. Anyway, after quite a while I made it without injuries; and the good thing was: We'd gotten a pretty good idea where to find the sign!
Our GPS this time was a lot better than the Australian one; still we've seen better devices. Driving through the hills of Hollywood was the next nightmare. It's all narrow streets, sometimes one way, and it takes you ages to reach a certain point. It reminds you of driving in Oslo (Norway), and there is also a remote similarity to the part of Zurich (Switzerland) situated on the hillside. Driving from there to work every day will cost you lots of time, and the view isn't that good either – quite often you just see the roofs of other houses and the horizon lies in the haze (another serious problem when trying to get good pictures in the Hollywood bowl!). We had no idea why someone would want to pay a million dollars or more for a small home in this area.
In the late afternoon we had finally gotten as close to the Hollywood sign as one could get. It is not allowed to hike up or do anything else except taking a picture. Lots of full-size helicopters are circling over the area all the time. We especially liked the above information sign: If you try to reach the big letters, they will either arrest you or/and you will have to pay $103. Not $102 and not $104, but exactly $103! :-) We could name more such cases where every last dollar matters.
To tell you the truth, the big white letters and the scenery around are nothing to really get you excited. Since there was not much space for flying anyway we decided to only take a couple of cool pictures rather than a video. The result was nice and worth all the trouble, but the film sequence would never have made it into the final WSF movie. We therefore put the machine away right after the flight – a good decision since not much later one of the air patrol helicopters came looking, and another few minutes later a patrol car showed up. This was exactly the time we left, so they just talked to a couple of other tourists which happened to be in the wrong place at the wrong time. :-) Having said this, we don't think it was us who attracted the air patrol.
Yesterday evening and the whole day today we drove a total of 800 km through the Mojave Desert. Currently we are close to the Grand Canyon national park and hope to get some impressive footage there; fortunately no snow yet!
This evening I finally found the time to replace the Three Dee MP-XL's old main drive wheel; it looked as if bigger load changes would have killed the remains of what used to be its teeth. Let's hope the problem is gone now, at least for the second part of this world tour.

Hawai'i – Outpost of Civilization?
Hawai'i is a piece of intact world. Hundreds of good-looking people lie on beautiful white beaches as far as the eye can reach, the water is clear and blue, the girls wear colourful bast skirts and sing and dance all day long. Coconuts are for free, the sun shines all the day, cool music plays and the only word you have to know is "Aloha" after they hang one of the many nice flower garlands around your neck. This is Hawai'i – or is it not?!
Nope, it isn't; not at all! Hawaii is situated right in the middle of the Pacific Ocean and is actually a group of islands; the larger ones are scattered over almost 1,000 km, and when also counting the most remote ones then it is over 3,000 km in total! Culturally they belong to Polynesia and to some degree unite Eastern and Western culture. Hawaii joined the United States of America in 1959 as 50th state and today has a respectable population of about 1.3 million people. Doesn't sound too much? Wrong, because the islands are quite different from the pictures that travel agencies spread all over the world. 75% of the population live on the main island Oahu (O'ahu), 400,000 alone in the state capital Honolulu; the rest is spread over smaller cities mainly along the south coast. Taking all of this into account, it is quite densely populated.
About 40% of the residents came from Asia (mainly Japanese, but also from the Philippines and China), further major ethnic groups are people of European (25 %) and Polynesian (< 10%) origin. Main languages are English (sometimes the very local version of it) and the original Hawaiian language.
Okay, so where are the beaches? Well, the most famous one certainly is Waikiki beach, a surfer's paradise where the waves can grow to a size of several meters. Hmm, does this mean it is very windy there?! Yep, you got that point … ;-)
We've only seen Oahu and think it shouldn't be famous for beaches. Instead, the unusual looks of the high mountains and the steep shoreline are most impressive; after all, Hawaii is almost entirely of volcanic origin! They simply grew from the bottom of the sea some million years ago. On the Big Island, called Hawaii (just like the state itself), there are still active volcanoes. They'd have made a perfect backdrop for WSF, but unfortunately we didn't have enough time to go there (about 400 km by sea). Thought Mt. Everest was the biggest mountain of the world? Well, its summit certainly is the highest point above sea level, but when measuring from the foot of the mountain to its top, then Mauna Kea is the world's tallest mountain with almost 9,500 m!
When returning from Ayers Rock to Sydney it was quite late at night, and since our 9.5-hour flight to Honolulu left early the next morning it made not much sense to spend money on another hotel night but to sleep at the airport instead. They close it at night but you could stay in the train station next door. Below's a shot taken at 3 AM showing what sleeping in an airport looks like.
We dozed most of the flight since we were eternally tired – but no worries, we crossed the international date line and that means we won a day (or one night to be more exact). Usually you lose time when travelling eastwards; not so when crossing the date line! In Australia we were 10 hours ahead of CET, in Hawaii we were suddenly 12 hours behind. It's sort of a déjà vu feeling when the date changes from 11th to 12th the second time. Winning a day like in the famous novel by Jules Verne (which was based on a more or less true background, BTW) was one of the main reasons why we chose travelling around the planet in eastern direction.
Hawaii is an expensive place! We found out the very first minutes when taking a taxi to our hotel. The driver was the unconventional type of person – we could not really understand what he said since the bass of his subwoofer was so strong that we got worried it might actually disintegrate the heli in its transport box in the trunk. Anyway, we reached the hotel and got a nice flat in the 23rd floor; we could even see part of the shoreline, so that was pretty cool.
Again, where are the beaches? Since Oahu is a modern island and the life style fairly typically American it was clear we needed a rental car. So we got one and started driving around to find a suitable WSF location. Not an easy task! Like said before, there is no such thing as the typical island paradise beach with a nice lagoon; the island is mostly covered with mountains. Theoretically you could drive around it, but there is a point where you need 4 wheel drive to continue!
How about Pear Harbor?! It is the most important US military base in the Pacific and gained fame in a tragic way when the Japanese killed over 2,000 people and sunk eight war ships during their plane attacks in 1941. It might have looked cool to do a long tail slide over some navy vessels and pull up just a couple of inches off the deck, but then …
After some time we figured that typical of at least this part of the Hawaiian Islands are mountains of volcanic origin (like the famous Diamond Head), plus beaches with waves and some palm trees. This would be a healthy mixture of the real Hawaii and the pictures in travel catalogues. So we just continued driving …
On day 2 we finally found a really good location. The wind was insane, look for the palm trees bending in the final video! One more time that one definitely misses the smoke trail of I/C helis – that'd have been a very cool look! After the flights we continued to Sandy Beach to take some static shots (no more battery packs!). As for that wave: No, I didn't see it coming!!
We went back to the hotel later that night (the sun goes down at 6 PM already), perfectly in time to collect the two FP 4900 mAh battery packs from Rainer Hacker. Nicolas and BBT had also fedexed a new RM cap (yes!) plus a spare main drive wheel and a vertical fin (remember, in Korea some guy stepped on it).
Back in the room we realized the video shots were bad – too shaky. Not good because it meant we'd have to return the next day after noon; earlier didn't make sense since the sun would be in the wrong place. What's more, I had worked on the computer until 6:30 AM and thus was really tired.
Anyway, we decided to drive to the same spot the next day. It was even more windy and the clouds moved fast thus leaving only short time slots for the flights. The scenery is great when lit but looks like nothing when the light is gone.
Despite the time pressure we did an AFD panorama as well. The fixed wing guys will hate this one! However, there was no better alternative and this way you can fly at exactly the same spot that we chose. Personally I love the challenge of landing an airplane here; you'll have to come in close to yourself in order to avoid the 10 m high bush work in just a few meters distance (I guess that's where most people will end up) – but still high enough to fly over a bench and a table nearby! Quite a challenge, but there is some stones in the water which will help you on approach. Like said before, you'll hate it at first but love it later on! :-)
For heli pilots it is no problem anyway; I'm just sad that the strong wind and thus some of the flair will be missing. Maybe Ikarus should ship a ducted fan together with the simulator, and it activates automatically once you choose this very scenery. ;-)
It took us about one hour to disassemble the heli and pack it into the box for the flight to California. We then rushed back to drop the rental car, collected the rest of our baggage, repacked parts of it and then went to the airport. Hmm, we really liked Hawaii – a shame it was over before we got the chance to see more of it. I'm actually typing these lines while on the plane to California – we'll come up with more cool news from there, so check back soon!

Ayers Rock – Spirit of the Aborigines
The next day we got up at 04:30 AM (don't ask when we went to bed!) in order to drop our rental car before boarding the plane to the Australian Outback. Due to a little confusion at the filling station (the rental company had no signs in the car at all what fuel it uses) we ended up with the wrong fuel in the tank – and broke down a kilometer later, still four kilometers away from the airport. It was clear we'd miss the flight; luckily a nice guy from Peru helped us and took Saskia to the airport. While she arranged that Qantas gave us a later flight I was standing in the rain for 2 hours waiting for a tow truck and dealing with the rental car company. Shit happens!
Ayers Rock is simply amazing! In the language of the local Aborigines it is called Uluru; not too far from it lie The Olgas (Kata Tjuta), another interesting rock formation and significantly larger than Ayers Rock. Both were formed about 800 million years ago in the same geological process; the whole land was flooded several times, and mud, sand, gravel, pebbles, rock, etc. accumulated in depressions. The whole mixture got heavily compacted (we're talking about geological time spans here!) and was finally pushed back to the surface. Erosion formed the structures visible today; and yes, this means we just see the tip of a much larger formation extending a couple of kilometers down into the earth. Please note that unlike Kata Tjuta the Uluru mainly consists of arcose sandstone; its original color is grey, but it contains a significant amount of iron minerals. The weathering process forms iron oxides which account for the nice red color; the whole mountain and desert around are rusting, if you want. :-)
Ayers Rock is about 350 m high (The Olgas over 500 m) and has been declared world natural heritage by the UNESCO (yes, these guys are everywhere! It is a mere matter of time until the whole planet is a UNESCO world something heritage …).
The local resort is called Yulara; it's basically a couple of hotels around a ring road including a supermarket and a filling station. That's it, and you won't find anything else in a radius of several hundred kilometers. The main language there is German! :-)
We inspected our baggage and found that the "fragile" stickers of the airline actually mean "please drop it extra hard!" Repairing the Three Dee MP-XL took about three hours, but it was nothing that couldn't be fixed. On this occasion we discovered that the main drive wheel showed strange signs of wear (see picture). The teeth in four parts of the gear wheel were heavily worn leaving big grooves between what's left of the original teeth. The four areas are the consequence of a slight noncircularity of the drive wheel (that's nothing unsual). As to what causes this strange kind of abrasion effect we're not absolutely sure. We have marked everything and will inspect it after every flight.
BTW, our last FP 4900 mAh pack was significantly ballooned after the air transport from Sydney to Ayers Rock – this is actually the first real indication that the constant transport under low pressure conditions may be (one of) the problem(s). The spare packs from Rainer Hacker (fedexed by Nicolas and BBT) should reach us Tuesday evening in Hawaii.
Both Uluru and Kata Tjuta are sacred in Aborigine belief and they were given back to them by the Australian government in 1985. Today the whole area is a national park; you can visit it for a fair entrance fee but have to follow the rules which means don't leave the marked paths, only stop in special viewing areas, etc. Not so good for flying; but then, there weren't too many people around so you could just jump over the fence or walk a little into the desert. Temperature? We had everything from 10 to 30+ degrees centigrade.
Okay, are the flights a homerun then? Not really, for several reasons. First difficulty is the weather; at least during our short stay it kept changing constantly. The funny thing is that the clouds appear out of nowhere within half an hour, but they do not move. After some time they simply dissolve and rematerialize somewhere else. The very moment it gets cloudy the wind freshens up to a point where your cap gets blown off; this can happen within less than five minutes. The next thing is, clouds cast big shadows onto the Rock – and this makes it look very dull in the picture.
The bottom line of all of this is: Find a good spot to fly where the Rock is not too near (so it'll fit into the picture) but still looks impressive, then wait in the car for as long as it takes, and when the lighting situation seems to get well jump out and fly.
The hotels at Yulara Resort provide (expensive) internet access; you get a fast download connection, but the upload is as slow as 2 KB/sec. which means most programs give up due to timeout when uploading pictures. This was the reason why we couldn't update the blog for three days. But transfer of the digital material to the computer, picture screening and selection, then post production and finally data backups kept us over-busy anyway. It's insane how much time such straight forward computer work takes – one day is nothing at all!
All in all the trip to Ayers Rock was both a success and adventure. To those of you appreciating the silence of a desert, the only sound being caused by the wind flowing over the landscape, combined with a clear vision till the "end of the world", we can only recommend this place.
The very cool image above is a pure HeliGraphix shot outside the WSF. Apropos, don't forget to check out our regular website as well! In our latest video we explore what happens if you fly with your R/C helicopter through a car wash. :-)
