I had one way back in the 70's. It has a semi symmetric wing and flys real good with an OS 40. Cramped up front but it will fit. Elevator and Rudder servos back near the tail for CG. RCM did a review of this "ready to cover" model and they put a 40 in ther's as well, don't know if I still have the artical any more or not. It did slow down nicely for landing. As I recall mine had a fixed - non stearable nose gear. It worked but elevator dual rates needed to be set high as the only way to turn it while taxiing was with full up elevator and juicing the throttle! Do yourself a favor and pick up a stearable nose gear -- my only suggestion. But it is still a nice looking airplane!
