The Trek features a cable-braced hang glider-style high-wing, weight-shift controls, a two-seats-in-tandem, open cockpit, tricycle landing gear with wheel pants and a single engine in pusher configuration.
[1] The aircraft is made from bolted-together aluminium tubing, and is commonly fitted with the Air Creation Fun 450 wing, which has a single surface covered in Dacron sailcloth.
The 10 m (32.8 ft) span Fun wing is supported by a single tube-type kingpost and uses an "A" frame weight-shift control bar.
The powerplant is a Japanese, twin cylinder, air-cooled, four-stroke, dual-ignition 60 hp (45 kW) HKS 700E engine.
This engine choice provides similar reliability, smoothness and fuel economy to the Rotax 912, but at a much lower cost.
