Piper Chuck,
Good choice, I had two of um, a bunch of us raced them for fun at my old club.
My non-race plane had a K&B Screamin 48 in it and was clocked at 99 mph. The early versions had soft landing gear wire and had to be checked for alignment constantly but were easy to straighten, I think the new versions have been improved.
As I remember the landing gear uses a standard servo but it needs to be a "high torque" servo.
