This orthodox helicopter had a two-bladed rotor mounted on a universal joint, and a small ancillary rotor with servo blades to regulate cyclic pitch and ensure stability in the main rotor. The latter was located immediately above the engine. The anti-torque tail rotor was placed at the end of a monocoque boom made of plywood.

Bronislaw Zurakowski, one of its designers, acted as test pilot during the early trials.
