The aircraft's model number indicates that it was designed to comply with the Federal Aviation Administration FAR 103 ultralight rules. The Aerolite 103 features a high wing with half-span flaps that are extended by use of an overhead bellcrank to a maximum of 40 degrees. The flight controls are three-axis and are actuated by a wheel mounted on a control column via flexible push-pull cables and conventional rudder pedals connected to the rudder by cables. The engine throttle is a twist-grip type and incorporates a brake lever to operate the non-differential mechanical drum brakes installed on the main wheels of the tricycle landing gear. The aircraft has conventional nose wheel steering connected to the rudder pedals. The main landing gear utilizes sprung-tubes for suspension and absorbing landing loads. There is a fourth small caster-wheel under the tail, because when the pilot's seat is unoccupied the aircraft rests on its tail, due to the aircraft's empty center of gravity. The Aerolite 103 is sold as an assembly kit aircraft. The kit includes an illustrated assembly manual and pre-built fuselage, wings, control surfaces, jury struts and struts. The wings are covered by the builder with pre-sewn Dacron envelopes. The company estimates the time to complete the airframe at 60–80 hours. The kit does not include powerplant, propeller or instruments.
