I've had my P3P for about 2 months now. No crashes so far but I have been very cautious. As my confidence grows my cautious approach is sure to fade. Are there certain manuevers that can result in a tumbling crash? How about certain stick combinations, i.e. Yaw and roll at the same time, descend and roll together, that should not be attempted? And if things start to go bad will letting go allow the bird to recover and just hover in place? Thanks.
