Iron eagle, thanks for your response regarding the use of the rudder. I just read that a lot of rudder input was needed, but didn't know the reasons.
I'm not learning to fly in this plane, this is actually my 4th plane (2 kits before and 1 arf). I'm still a beginner, though, that's why I asked my question in this forum.
I just wanted to make things simple, that is the reason about my question about mixing ailerons/rudder.
Thanks!
