[1][2] The aircraft is made from bonded and pop riveted aluminum sheet and has a 26.0 ft (7.9 m) span wing.

Optimized for simplicity of construction, the design has no compound curves and requires no jigs or special tools.

The standard engine intended to be supplied with the kit was the 55 hp (41 kW) two-stroke Hirth 2702 powerplant with a reduction gearbox that allowed the propeller to operate at lower tip speeds.
