Design and development

The Convertible was designed to comply with the US FAR 103 Ultralight Vehicles rules for single seaters, including the category's maximum empty weight of 254 lb (115 kg). The aircraft has a standard empty weight of 245 lb (111 kg). It took its name from the design feature whereby it can be fitted with a second seat for instruction or passenger carrying.[1]

The model features a parachute-style high-wing, single seat, or optionally two-seats-in-tandem, accommodation, tricycle landing gear and a single 50 hp (37 kW) Rotax 503 engine in pusher configuration.[1]

The aircraft is built from a combination of bolted aluminium and stainless steel tubing. It features a double ring propeller guard that has been roll-over tested. The 5 U.S. gallons (19 L; 4.2 imp gal) fuel tank is made from aluminium. 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.[1]

Originally marketed by the factory under their own name, the aircraft was later marketed under the brand name Blue Heron, although the manufacturer remained the same.[1]

gollark: I mean, "gaming" ones often don't have good battery life and are loud/heavy.
gollark: Eh, kind of?
gollark: ... do they *have* any AMD ones?
gollark: Anyway, do you want a particularly portable laptop or do you not care much?
