Default RE: HIGH SPEED STALL

While Ihave not measured the G my model aircraft are subjected to, Iam quite sure that they are so much stronger than full size aircraft that it would be quite possible to pull 15 and possibly even 20 Gs without breaking them. We don't know what speed our airplanes are flying at and, as their power is greatly in excess of full size aircraft, they can reach these high Gs without stalling. On the other hand, we use, let's call it higher speed stall, in snap rolling manoeuvres all the time in aerobatic schedules so to say that model aircraft don't stall is quite wrong. You can set one up to have insufficient elevator authority such that you would find it difficult to stall by approaching the stall fairly slowly. Pulling the aircraft up to a very steep attitude even with limited elevator travel will usually produce a stall but the recovery, given that small elevator movement, will be almost instantaneous so it will "look" as if it has not stalled. Idon't know how many folks have lost an aircraft on short finals to the dreaded stall/spin situation - Icertainly haveand I've seen quite a few others go that way!
