Single seat single engined high wing mono¬plane with conventional three axis control. Wing has elliptical planform and tapering chord; inverted V tail. Pitch/yaw control by elevon; roll control by wing warping; control inputs through stick for pitch/roll and pedals for yaw. Cantilever wing; wing profile; double surface. Undercarriage has three wheels in tricycle formation; suspension on all wheels. Push right go right nosewheel steering connected to yaw control. No brakes. Aluminium tube framework, without pod. Engine mounted below wing driving pusher propeller.

Conceived by J Bruce Emmons, the Eclipse was one of the new releases at Sun ‘n’ Fun of March 1983 at Lakeland, Florida. The Eclipse is also the first rigid wing ultralight to use wing warping for roll control (with the possible exception of the British Ladybird, which is not yet in production). With the Eclipse, the accent has been put on flight stability. The strength of the airframe has not been neglected, this ultralight having been static tested to as much as ± 9 g, more than the requirements for a light aircraft to be classed in the aerobatic category. The wings can be placed parallel with the framework by removing three bolts; demounted like that the machine can be transported either on a trailer or a roof rack. All the pieces in the kit are delivered pre formed, cut and drilled. Sold for $5495 in 1983, the kit thus provided is claimed to need only 30 h for completion.
