Really like the digitals. Fast and accurate.

Engine Saito 72. Would go with YS 63 or Saito 91 if I were you. Definitely go four stroke for swinging a larger prop. Started with 13x6 then 14x6. Too much pitch and too fast - not for me just for the plane. Have someone at the field that has a profile and can't fly very well. All he does is fly full throttle and around in circles. Currently have a 15x5 on it. Great prop slows down wonderfully and really torques for tumbles and flips.

Put TALL aftermarket Ultra Stick gear with H9 3.5 inch lightweight wheels. This is necessary with a 15" prop.

I used ball link ends and a pull pull on the rudder.

My CG is 1/2" back from recomended setting.
