My roo is set up at 0 AOA but will still bounce if I land too hot. Although the AOA adjustment might help a little, the key is to hold the plane 12" off the deck till it settles itself in. They will bounce regardless of AOA if you carry too much speed into the landing. You have to learn to transition the plane into "Slow Flight" before you enter the landing pattern. This is the easiest way to land the roo/rookie slow. While making a turn, drop the gear and speed brake (no pitch change if dropped during a turn), on an upwind pass pull the power off until the speed bleeds off, just before the plane is about to stall come back in with just enough power to maintain controlled flight adding two or three clicks of power in the turns and pulling it back out as you exit. Maintain this slow flight through the entire landing pattern using throttle to control decent and elevator to control attitude. Practice the slow flight a few mistakes high until you can enter it with ease, you wont believe how much better your landings get! Dont be afraid to get the plane slow (I was for quite some time in the beginning) but get a feeling for what is too slow and how the stall reacts..... Dont land the plane, it will land itself! Hold it off the deck as long as you can....
Hope this helps,
Todd
