All the information and suggestions given so far have been good.

I have a Mojo 60 that will harrier all day at virtually any angle a friend has a Katana 70 and it wing-rocks very badly unless you get just the right angle and just the right amount of power/elevator.

Some models are better than others it's just a simple fact.

The only thing that will *really* reduce the wing rock in a plane that's predisposed to such things is practice!
