Though not an engineer, nor an aerodynamicist, enough years of flying, teaching, some aviation science courses, and much studyingin both arenas, has led me to the conclusion that it often "all depends". As Pimmnz said, "not all models are created equal". The short of it is, that lacking any certifiable spin recovery technique (and you have to revert to spin recovery techniques since we are beyond the stall event),one age old recommendation is: ensure throttle is at idle, neutralize ailerons, then apply FULLrudder OPPOSITE to the rotation. In the case of an actual airplane,applying full rudder meansto the stops; however, with the model it may be somewhat less given the amount of rudder area typically found. I did experiment with this because back in the dayI also couldn't figure out why any of my pattern planes recovered from the 3-turn spin in like fashion. A number of years later I found the technique to be very useful in recovery the model from the spin. I fly single stick and typically twist the knob rapidly opposite the spin, and push, it generally takes a few moments of a second maybe two and the spin stops. Practice then makes for smoothness. Just amethod that you might want totry Jeff. The technique works well in actual aircraft too. I built and fly a RV-6. It has no spin recovery technique per say since it's an experimental. When it enters the spin it develops into a very rapid rotation which stops very abruptly with full opposite rudder and a bit of push. After five turns it requires a bit longer to stop and a bit more push toreduce the high angle of attack (I haven't gone beyondfive turns!) Oh, I do not use ailerons to enter the spin either (as best I can tell) the stick is neutral as far as the ailerons are concerned. There may be some wiggle, but it's not intentional on my part. Sorry to butt in, I did find it an interesting question and comparison.
