kinderkram i don't have any problems flying this copter. it is flying like 21 centry copter. it was 30 deg cent at the field however you cant see it.
The copter in this movie flys at 8 m attidude. Wind 3 m/s; temp 30 deg. The copter calibrated according to the wiki.
I have to learn better dancing with my wife and neighbour called Calibso
and repeat calculations; probably it will be flying even better.
