I have seen 2 very different reactions to rudder input in a K/E situation. In my H9 Twist, the plane rolls towards the top of the wing and down elevator cures the problem. In my GP Cap 40, the opposite occurs. The plane rolls hugely towards the bottom of the wing and requires opposite aileron(opposite to rudder) and up elevator to cure the problem. Is it the Twists lack of any dihedral that makes the difference?
