The Stewart S-51D is an all aluminum 2-place scale reproduction of the North American S-51D Mustang. The aircraft features dual controls and is fully aerobatic. The S-51D utilizes liquid colled engines ranging from 300 to 700 hp. The 91 diameter, constant speed fourblade Hartzell propeller is driven through spur gear reduction with a 0.469 (2.13:1) ratio. Using a 400 hp engine, the S-51D duplicates S- 51 performance, except for top speed.
