Pangong Tso lake! wow a paradise on earth. you are really a privileged man.       

Eagerly waiting for the video. 

I uploadeda  video made out of the two short FPV flights I could do with the tricopter at Pangong Tso.

Wow, what a beautiful place now i want to go fly there.
4500 meter! Was the tricopter modified in any way or were you able to fly your regular setup??  Also interested in flight report of the twin boom, that thing has very small wings to fly at such high altitude.

its simply awsome ...was treat of my eyes....
can you please post a few pics of your tricopter tooo
hat off to you mann

The tricopter was exactly the same as I fly it here in Bangkok at pretty much sea level. I used 10X5 Slow Flyer propellers. I had carried an assortment of other propeller sizes (12X6, 10X6 triblade, 10X5 APC, etc...) to test, but in the end I flew it as normal.
However I needed much more thrust to hover, close to 90% I think.

I'll post some photos of the tricopter later and the video of the airplane. The airplane had no problem whatsoever to fly at that height, I only needed to toss it much faster than at sea level to take off.

That is very very beautiful video..!! 

hi mate.
very nice video...........It looks very much as though the lake is receding?
is this right? due to global warming?
beautiful location.

fabulous video and marvelous flying there 

I don't know if the lake is receding, you'd need to check the water level over a period of time for that.

Here's the second video, shot from the small FPV plane this time. It uses a lower resolution camera and is less stable than the tricopter, but very fun to fly.
