The Phoenix is a derivative of the Urban Air Lambada motorglider, developed by Martin Stepaneck who was formerly with Urban Air before that company's demise. The Phoenix was designed to comply with the Fédération Aéronautique Internationale microlight rules and US light-sport aircraft rules. It features a cantilever wing, a T-tail, a two-seats-in-side-by-side configuration enclosed cockpit under a bubble canopy, fixed conventional landing gear and a single engine in tractor configuration.
The aircraft is made from composites. Its 151NaN1 span wing is convertible to 111NaN1, by removing the wing tips and then re-installing shorter tips and the winglets for faster cruising speed when flying as a microlight. With the wing tips removed it has a wingspan of 10.41NaN1 for storage. Standard engines available are the 800NaN0 Rotax 912UL, the 1000NaN0 Rotax 912ULS, 850NaN0 Jabiru 2200 and the 600NaN0 HKS 700E four-stroke powerplants. With the 912S engine the aircraft can be employed as a glider tug. An electric-powered version is under development.[2]
The European version has a gross weight of 472.50NaN0, while the LSA version has a gross weight of 6000NaN0. The design appears on the Federal Aviation Administration's list of approved special light-sport aircraft.[3]
