Quad City Challenger

quadchal


Single-seat single-engined high-wing mono-plane with conventional three-axis control. Wing has unswept leading and trailing edges, and constant chord; cruciform tail. Pitch control by elevator on tall; yaw control by fin-mounted rudder; roll control by spoilers; control inputs through stick for pitch/roll and pedals for yaw. Wing braced from below by struts; wing profile; double-surface. Undercarriage has three wheels in tricycle formation, with additional tailwheel. Suspension on all wheels. Push-right go-right nosewheel steering connected to yaw control. Aluminium-tube framework, partially enclosed. Engine mounted at wing height driving pusher propeller.

Designed by Dave Goulet and first flown in 1983, this ultralight made its debut at Sun 'n' Fun in March 1983 at Lakeland, Florida. Thanks to the fabric covering the whole of the framework and a windscreen over the cockpit area, it has an excellent glide ratio, 11/1 being claimed by the manufacturer. At that time little detailed information was available from Quad City Ultralights on what was really no more than a prototype, but since then the Challenger has gone on sale as a kit requiring 50 h for completion and costing $5495. Rigging time is expected to be in the order of 30 min by one person from a trailer, according to the manufacturer. The aircraft can also be towed on its own undercarriage.

Power comes from the KFM 107 with electric start and reduction drive.

In 2010 LSA Quick-build kits were from US$9,215 to US$12,965 ex engine  and engine options were Hirth F-33, Rotax 447/503/582, and HKS 700E.

The Challenger qualifies for Part 103 ultralight or 51% kit for Experimental - Amateur-Built, can be flown with Sport Pilot Permit, and qualifies as a Light Sport Aircraft.
