another thing about spins as well that i have been experimenting with on my models is to slow the plane down as if you are going to do a stall and then add a little left rudder and as soon as it drops the wing add full left rudder while holding the elvater and full left rudder and neutral aileron with throttle at idle do this, begin to releive the elevator to neutral slowly and see what happens, the model should continue to remain in the spin and it should accelerate as well in other words wind up even faster, I have been doing it as well after i get my gp ultimate in a flat spin as well how i do the flat spin with it is power at idle and slow to stall and enter in a normal spin as soon as it spins i start adding throttle and right aileron as soon as i get it flat with full left rudder, full up elevater, full power, and full right aileron I start to take the elevator out but leave everything where its at and it also accelrates its rotations as well and slows the vertical decent.

I learned this technique from flying our full scale pitts and a friend of mine giving me some advice on spins and what not, i havent preacticed flat spins in the pitts but have messed around with the standard spin and moving the elevator forward but not pass neutral since I figure it will then break into an inverted spin more than likely but it is pretty awsome and interesting to see what the inputs do and also to see how the model acts just like the full scale.

also in the full scale pitts when i snap it I do a quick pull aft elevator to the stall and then stand on the left rudder as soon as the plane starts its rotation i bring the elevator forward, take into account no aileron if anything aileron in the oppisite direction of the snap, but when you bring that elevator forward it causes the plane to accelerate a lot which on my model I have noticed this technique works well for my biplanes not my extras, anwyay just thought the snap rooll stuff was interesting to see how the elevator can make so much difference.
