i have a saito 1.20 in mine with digitals on ailerons and rudder.......elevators have standard bb jr servos.

The 1.20 just drags this plane around with a 16 x 6....never are you short on power....it will hover a lil under half throttle and will pull out a lil over half The 100 is prolly the perfect motor for this plane. Either that or the super charged ys .91

FIRST PAGE IN INSTRUCTION SAYS DO NOT POWER WITH 1.20 :0

The only problem i have seen so far is that it won't get that true flat spin.(gonna move cg back a lil and a lil more throw on elevators to see if that helps some).......and when it torque rolls......it don't roll and if it tries..it is really really slow......it will hover like a champ though....just don't roll that much.

This plane is a blast to fly...many at my field has had some stick time on it.....and some offer to buy it.
hope this helped some
