The GP Pitts, properly powered and set up, is a wonderful biplane to fly. It likes to wheel land much more than to three point. It does not have any snapping problems, and performs all the usual areobatic manuvers extremely well. It will also do some very light 3D stuff, but keep in mind that it really wasn't designed for 3D. It has a VERY wide weight and C/G envelope. Well outside the manufacturers suggested range.

Once you have enough power, avoid full power snap manuvers. Do them like you should and reduce power prior to the snap entry. The older versions had a tendency to break the top wing cabane mounting brackets. Especially on negative snaps. The newer kits have a re-designed mounting bracket.
