[1][2][3] The single seat Javelin I was designed to comply with the American FAR 103 ultralight regulations, including that category's maximum 254 lb (115 kg) empty weight.
The Javelin was introduced circa 1999 and was intended to appeal to pilots who wanted to experience totally open-air flight.
The wing is framed from riveted aluminium tubing with all flying surfaces covered in doped aircraft fabric.
[1] Original factory kit options included a cockpit pod and windshield, brakes and steel tube powder coating.
The T-Raptor uses a wider and more enclosed fuselage, with optional bubble-windowed doors, to allow cool weather flying and was intended to be marketed to ultralight schools.
