RE: edge 540t or extra330s?
My edge harriers very easily! You have to keep the throttle constant or the changing throttle settings will make the plane rock, but if you keep that under control it is very stable. The plane hovers, and TR's great! This plane gets in the "zone" and as long as you keep it there it will spin around and around in a TR. It also does great pop ups, and elevators. I can't think of anything it doesn't do well. It's a great flying plane!
