Electravia Monotrace-E

The Monotrace-E was designed as a soaring motor glider, to comply with the Fédération Aéronautique Internationale microlight category and the US FAR 103 Ultralight Vehicles rules.^[1]

The aircraft design features a cable-braced hang glider-style high-wing, weight-shift controls, a single-seat open cockpit with a cockpit fairing, tricycle landing gear and a single electric motor in pusher configuration.^[1]

The aircraft is made from bolted-together aluminum tubing and composite materials, with its double surface wing covered in Dacron sailcloth. Its 10 m (32.8 ft) span wing is supported by a single tube-type kingpost and uses an "A" frame weight-shift control bar. The powerplant is a 26 hp (19 kW) E-Motor GMPE 102 electric motor, powered by a Kokam battery pack and driving an E-Props propeller, giving about 25 minutes endurance.^[1]

The aircraft has an empty weight of 85 kg (187 lb) and a gross weight of 193 kg (425 lb), giving a payload of 108 kg (238 lb).^[1]
