Have one also with a magnum 91 but is to much weight in the plane nose. It sure have power for hovering but that is all I can get, no flat spins or other 3d maneuver and the landing gear
have to be change for prop clearence. If I have to pick another engine for the SE I think I will choose from a light .50 2stroke,
saito .72 or a YS .63.
Happy landing
Benny
