Dubbed the Gyro-Glider it was the first of several such designs that would be sold by Bensen Aircraft Corporation over the following decades.The B-5 was built around a cruciform frame of aluminum tube. A landing wheel was fitted to three points of this cross and a mast was fitted above its centre to support the rotor hub.
