That was actually one of the inspirations for mine. I found that link shortly after starting my own. It is a great read. Adam Definitely! That was actually one of the inspirations for mine.

additionally at 60,000ft the air is about 1/10th of the density at sea level, so your stall speed will have increased by a factor of 3-4 you just have to make sure this doesn’t exceed your VNE, Spead of sound at 60,000fh 295m/s so your unlikely to encounter any compressibility issues…

Where I live the cellphone coverage is really bad though so we figured we'd never be able to retrieve it all. Nice man, we thought about doing the same thing.

I would love to see the flying video of your glider. Basically i'am also working on a small RC Glider (hand projected and unpowered in its locomotion) which can project a projectile at a distance of 50m . So can you please guide me in its design and its control (using reciever_transmitter set and servo motors) since i'm just a beginner. A wonderful concept and a more wonderful application.

The LCD is obviously from Sparkfun :) The blue buttons can be found here.

This looks like it has the makings of a really top-drawer project, but one which will certainly have its fair share of frustrations and surprise unknowns. I very much look forward to tracking your progress - I am about to start on a very similar project myself - we may be able to share notes. Ed cuspaceflight.co.uk Don’t give up!
