I had the Pitts M-12. It is definitely an exciting plane, but it made my heart pound when I flew it! You really have to be on the sticks! The Pitts will tend to fall out of a turn if you slow down too much.

I also had the E-flite Rhapsody. This bipe is much more tame than the Pitts, and a bit bigger. With the Power 32 motor and a 4S LiPo, she scoots along very quick, but slows nicely for landings.

But, if you're looking for something larger, a Skybolt is an excellent choice!
