US Aviation Cloud Dancer

The US Aviation Cloud Dancer is an American ultralight motorglider that was designed by Erwin Rodger and Roger Delura and produced by US Aviation. The aircraft was supplied as a kit for amateur construction.

Design and development
The Cloud Dancer was designed to be a motorglider that would also comply with the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of 254 lb. The aircraft has a standard empty weight of 252 lb. It features a cantilever mid-wing, a single-seat, open cockpit, conventional landing gear, a V-tail and a single engine in pusher configuration.

The aircraft is made from aluminum and fiberglass. Its 40 ft span wing with a 12:1 aspect ratio is built around an aluminum D-cell leading edge, with the aft part of the wing fabric is supported by removable fiberglass battens. The wing fabric provides an 80% double surface airfoil. The controls are three-axis, using spoilerons for roll control. Air brakes are also fitted. The landing gear features fiberglass suspension and the tailwheel is steerable. The wings are quickly removable and the whole aircraft was designed to be transported on the roof of a 1980s-era station wagon, taking 20 minutes to assemble or disassemble. The standard engine supplied was the 28 hp Rotax 277 single cylinder, two-stroke aircraft engine.

Production ended in 1994 and the conventional-tailed, but otherwise similar US Aviation Cumulus commenced production in 1995.
