The B1RD was available in single place configuration, but a two place ultralight trainer was also available from the company. The B1 RD was supplied as a kit taking approximately 100 hours to build. The kit featured bolt and rivet together aluminum tube construction covered in Dacron sail cloth. Like many early ultralights the B1 RD featured a kin post and wiring bracing.
Power was supplied by a number of engines including the Rotax 377, 447 and 503, as well as the Cayuna 430R. The original design used a belt drive, with a 68 inch two blade propeller. The engine was mounted in a tractor configuration under the wing with the belt drive point up over the wing.
Control system is standard three axis control, stick and rudder control, with a center mounted stick, and left hand throttle.
