given i've been flying couple months, I didn't use rudder in the beginning. Right i now i use high expo on my rudder and i ever so slight apply small rudder when i'm initiating a turn... that's it. and this is when i'm doing circles in the air. When I'm goofing around in the air, I don't use rudder at all except when landing, even then i line up and then bring the plane down and use my ailerons more to keep the plane leveled
