I fly alot of 3d and can perform most 3d moves including torque rolling down low,rolling harriers,and blenders down low. I also own a gp pitts and love flying it. It has a g45 on it turning a mens [email protected] motor is a bit heavy but it pulls it around pretty good,a little better than a scale one. Although this is a nice flying plane and dose awsom tumbles it is not a real 3d candidate. The main reason isnt the size of the surfaces,wich are large enough to torque roll,but the inherant instability of the short fuse. The first prerequiset to a good 3d bird is you should be able to cut the power and put full up elevator and the plane falls in a elevator without rocking bad. This stability is in the design of these 3d aerobats. Alot of the real 3d stuff revolves around the plane being able to elevator and harrier.My pitts, although a great aerobatic platform, is not capable of doing these things. I love watching the pitts falling back while torque rolling through the dense cloud of its smoke system. Thats why I got it.

Good Luck
