RE: TOWER FUN 51 ENGINE
prophanger,
I run an O.S. 50sx and a zinger 12x4 on mine. It has unlimited vertical and is real tricky! I am fixing to place a high torque servo for the elevator and a 4-40 pushrod on it. When I'm pulling some serious g's, the elevator rod bends and the servo seems to fail. I can hold the elevator while its on the ground and with a little preasure, the rod bends and the servo strains. Here are some pics of it.. You will really enjoy this plane!
