The Griffon was the first design produced by InterPlane when they opened for business in 1992. The Griffon was designed for the requirements of the US FAR 103 Ultralight Vehicles category, including that category's maximum 254 lb (115 kg) empty weight.[1][2][3]
The Griffon airframe is constructed from aluminum tubing, with the wings and tail covered with doped aircraft fabric. The wing is supported by a "V" strut and utilizes jury struts. It features a three tube tail that allows the pusher propeller to be located in between the tail booms. Standard features supplied included brakes, electric starting, wheel pants, elevator trim system and a plastic cockpit pod fairing with a windshield. The wings and tail surfaces can be folded for trailering or storage.[1][2]
Available engines included the 40 hp (30 kW) Rotax 447 and the 50 hp (37 kW) Rotax 503.[1][2]
