This is my first Contender and no one else in our club has one. I understand that the upswept wing tips are supposted to help in the "tip stall" dept.
I can't speak from experience on the yaw coupling, but I know from personal experience if the plane is build "straight" it flies exactly where
you point it. In knife edge it requires no trim, no tendency to couple to the canopy or wheels.

I am looking forward to gaining more flight time. This is a fun plane. I have a .61 OS FX on mine and it is fast!!!!

I wish you the best.
