ISBN 0-9636409-4-1〕 The single seat Javelin I was designed to comply with the American FAR 103 ultralight regulations, including that category's maximum empty weight.〔〔〔 Capella Aircraft went out of business in late 2007, and the type is no longer in production. ==Design and development== The Javelin was introduced circa 1999 and was intended to appeal to pilots who wanted to experience totally open-air flight.〔 The design features an open frame fuselage of welded 4130 steel tubing, with the pilot's and passenger's seats bolted to the frame. The horizontal stabilizer and tail fin are also constructed of welded steel tubes. The wing is framed from riveted aluminium tubing with all flying surfaces covered in doped aircraft fabric. The wing is equipped with full span ailerons.〔 The conventional landing gear includes sprung-steel main gear and a similarly sprung steerable tail wheel. The open cockpit design provides good visibility while taxiing.〔 The standard engine supplied by the manufacturer for the single seat version was the Rotax 277, but it was reported that the aircraft was underpowered with that engine installed. The throttle control is of a unique motorcycle grip type.〔 Original factory kit options included a cockpit pod and windshield, brakes and steel tube powder coating.〔 The single-seat Javelin was developed into a tandem two seater, designated the Javelin II and then further developed into the T-Raptor ultralight trainer. 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.〔〔Cliche, Andre: ''Ultralight Aircraft Shopper's Guide'' 8th Edition, page B-105.
