The Sioux was designed by Joe Wagner in 1949 as a foolproof 1/2A free fight, and incorporated several features that provided automatic stability in flight. In particular, the offset thrustline, fuselage and tail shapes, and right rudder tab, combined with the torque forces and gyroscopic effects caused by the spinning propeller, compelled the model to climb in left circles. After the engine quit, the model transitioned into a right-circling glide. This model may seem a little heavier and will fly slightly faster than you may be accustomed to, but this weight and speed are responsible for most of the models ruggedness and stability. The Sioux has a deliberately heavy structure for a Free Flight model, but remember it was designed to fly on full fuel tanks, without engine run timers. Flat slow sinking glides were not wanted or airplanes would be lost. The full size plans in this kit are hand drawn by Joe Wagner and used with permission. The BMJR Sioux is true to this original design with only miner exceptions to take advantage of laser cutting technology. Model has a 35 1/2" wingspan intended for 1/2A gas engines.
