I'm still a beginner, but I think what you're describing is the
pendulum effect. It is normal for <strike>helis with a 45° flybar</strike>mSR (I didn't know what I was talking about...). I think the solution is to back off on the cyclic gently, not just let it bounce back to center.
I was thinking of a Walkera v120d01 when I get a little better with the mSR for outdoor flying. What do all the more experienced pilots think about that?<br type="_moz" />
