Now I'm beginning to understand what you are saying - how much throttle are you coming in with (downwind, base leg, and final)? It also seems that you might have your idle up to high if it is speeding up on final. As for the bouncing, that might be becuase of the music wire landing gear (if so equipped). You might want to consider making the plane a taildragger with a little more rigid landing gear. You could also consider adding flaps if your radio will allow it (usually a 6 channel computer radio). That would slow the initial speed and would be a big help in slowing the plane on landing. Most trainers I know of slow down very nicely when landing , but I have the engine just ticking over when the plane is at idle. You could also try and 11X6 or maybe even an 11X& on the .46. It might help also slow you down a little. I'm also wondering if you have a warp in the wing.
