he states in one of his posts everything he is using (see post #6 above)I call BS. The last video defiantly shows a curve to the earth.. and as we all know...
It's a risky flight and I wouldn't suggest doing something like that without having permission from the proper authorities. That being said, since it's already done, can we all just appreciate how awesome the view was?
Also, anyone have an idea what kind of quad he used? The video is titled FPV Racer.. but I would assume it would have been something a bit more industrial. it was -9c on the ground and upwards of -50c during his flight. So not just it's insane transmission range and lift generated at that altitude, but the fact that it was able to survive at that temp for as long as it did is just crazy. Would the battery have to have some sort of thermal protection?
and as for the battery it says:
