Rcguy,
Throttle management is the key to your problem. Always be ready to add throttle when you bounce like that. If you have room on the runway just fly out of the situation by adding a little throttle before your airplane can bounce again. If you don't have the runway left then go around and try the landing again. Practice makes perfect and a lot of us would be better off flying a couple tanks a week shooting landing approaches in all kinds of wind conditons than spending hours trying to perfect 3D. You gotta crawl before you can walk.
