Its several variants sold in large numbers. In 1987 a Flyer became the first ultralight to land at the North Pole. The Avid Flyer is a conventional layout, single engine, side by side two seat light aircraft, with a strut-braced high wing configuration. Aluminum tubes serve as leading edge/main spar and rear spar, each wing being supported by a pair of tubular lift struts. Sawn plywood wing ribs are bonded to the aluminum tube spars using a filled epoxy compound. The Avid Flyer features Junkers style one-piece flaperons supported by three offset hinge arms. The Junkers design moves the control surfaces well underneath the wing, where they remain in undisturbed smooth airflow at low speed and/or higher climb angles. The welded steel tube fuselage is flat sided, narrowing towards a braced cruciform tail group. The horizontal tailplane is carried on the fin just above the upper fuselage line. The aircraft's conventional rudder and elevator controls are cable operated. For more details of the design, operational history and four variants, click here.
