I have a Yak 54 with a 50cc on it...every time i try a knife edge, as soon as i apply the rudder (with the top of the plane toward me) it wants to curl away from me fairly hard. in order to keep it going down a straight line i have to use a fair amount up elevator to counter the curling away from me.

Any ideas as to what is might be causing this abrupt turn away when i try the knife edge?



Thanks in advance
