TruBlu02, yes, they taught usthat in pilot flight school back in 1976,and being an old timer, my memory is slipping a bit in the evenings after a couple of Taliskers....but, yes, you are right,there are more factorsinvolved thansimply transverse wing turning dynamics -true airspeed over both wings in a turnaffecting lift and drag on each side (but Falcon is concerned aboutROLLING in a straight line, not banking).

One also needs to checkaileron movement for binding limiting movement to one side, down/side thrust lines,lateral (cg) wing balance,positive/negative horizontal stab angle (bad build quality), skew fin, possibly warped wings, warped ailerons, unequal (unsyncronized)aileron servo movement, sloppy/loose hinges/control rods, improper programming ofTx, esp with electronictrims, zero and movement.Sometimes it could justbe a loose servo.....

Falcon 32 did not say which plane is doing it. Ifthe plane's set up is 100% good, high wing planes (Cubs etc) are more difficult to roll than low wingers, they have a natural tendency to roll out (corkscrew) .

If heis flying mode 1 or mode 2 - some right hand/left hand people find it easier with one or the other when it comes to aerobatics. Switching modes can also effect flying,On mode 2 the the elevator and aileron gimbal springs settings also have an effect. I prefer my mode 2 Tx gimbal spring to be slightly stiffer on the elevator than the aileron and on mode 1 the elevator gimbal spring stiffer than the rudder one,but that is personal preference.

But one need to try the very basics first, then go int the above checklist
