In flight steering is accomplished via foot pedals, or optionally a control stick, that actuate the canopy brakes, creating roll and yaw. On the ground the aircraft has lever-controlled nosewheel steering. The main landing gear incorporates gas strut suspension. The aircraft is factory supplied in the form of an assembly kit that requires 30–50 hours to complete. Originally marketed by the factory under their own name, the aircraft is now marketed under the brand name ''Blue Heron'', although the manufacturer remains the same.
