Six Chuter SR7

Design and development

The SR7's design goals included that it be capable of carrying large-sized pilots and passengers.

The aircraft was designed to comply with the US FAR 103 Ultralight Vehicles rules as a two-seat ultralight trainer or as an amateur built. It features a parachute-style high-wing, two-seats-in-tandem, tricycle landing gear and a single 64 hp (48 kW) Rotax 582 engine in pusher configuration.

The SR7 is built from a combination of aluminium and 4130 steel tubing. In flight steering is accomplished via foot pedals that actuate the canopy brakes, creating roll and yaw. On the ground the aircraft has lever-controlled nosewheel steering. The SR7 model was factory supplied in the form of an assembly kit that requires 40 hours to complete.
