[1] The aircraft was designed to comply with the US FAR 103 Ultralight Vehicles rules as well as European regulations.

It features a paraglider-style wing, single-place accommodation and a single 24.6 hp (18 kW) Hirth F-33 engine in pusher configuration with a 2.3:1 ratio reduction drive and a three-bladed, fixed-pitch wooden propeller.

The aircraft is built from a combination of bolted aluminium and 4130 steel tubing and dismantles for ground transport.

[1] As is the case with all paramotors, take-off and landing is accomplished by foot.

Inflight steering is accomplished via handles that actuate the canopy brakes, creating roll and yaw.
