RE: Great PLanes Pitts SU2 Crash Pics
Everything else aside, and for future reference, the 600mAH batttery was WAY to small. If all the servos in the plane were pulling their maximum draw in a stalled condition, the battery would not have had enough capacity to have supplied any usuable current to the receiver for signal processing.
That battery would supply 6/10 of an amp with a total servo count that could draw over well 2 amps.
I really feel for you due to the loss of your plane, and the manner in which it was lost. Befeore you fly your next plane, it wouldn't hurt to do a little research about battery capacities and servo types with their associated current draw.
