The J-4 Javelin, a single ship capable of carrying a child behind the pilot features an aileronless wing with spoilers for glidepath control and ‘spoilerons’ for roll control, the latter causing almost no adverse yaw. The wing spar is a chem-milled tube, and the airplane uses very few normal rivets, most fastenings being cost saving pop rivets. The fuselage is built around a steel tube frame, with a lower fiberglass shell bonded to aluminum sheet wrapped over the deck. The Javelin first flew in 1969. ATC.
