I have a question regarding the Aileron of the Thunder Tiger Slow Fly Cub. The instruction indicates that on low rates the ailerons should move 5/8” up and 3/8” down. Also, the high rates should move 1” up and 3/8 down. Why do I need to do this? And what are the consequences if I go to even throw up and down.

By the way this little bird is FUN to fly…
