Sport Copter Lightning

Design and development

The base model Lightning was designed to comply with the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of 254 lb (115 kg). The aircraft has a standard empty weight of 252 lb (114 kg). It features a single main rotor, a single-seat open cockpit without a windshield, tricycle landing gear and a twin cylinder, air-cooled, two-stroke, single-ignition 50 hp (37 kW) Rotax 503 engine in pusher configuration.

The aircraft fuselage is made from bolted-together aluminum tubing. Its 23 ft (7.0 m) diameter rotor is supplied ready-made and constructed from bonded dural aluminum by the company's subsidiary Sport USA LLC. The landing gear includes telescopic spring suspension. A semi-enclosed cockpit fairing with windshield is optional.

The basic Lightning design has been developed into the heavier Vortex.
