Hi all,

This plane seems to have very small rudders aera. I suspect this plane to lose the rudder effectivity at high angle of attack due to fuselage and wing slipstream, thus having some yaw movement and great variation of speed at tip end of the wing, thus improving tip stall tendencies. It's not rare with those "low profile" style rudders.

Have you noticed some yaw movements or snacking problems ?

Maybe a gyro on rudders, not ailerons, should help to keep the plane "straight in line" and thus not tip stalling. That's the first thing you learn when you fly reals ones : keep that ball centered !
Other help should be a slight negative aileron to put some negative washout at landing, but you said you've tried the crow function with no effects. (Please not too much negative, you need some lift...)
