The aircraft features a cantilever low-wing, a single-seat, enclosed open cockpit under a bubble canopy, retractable tricycle landing gear and a single engine in tractor configuration.[2]
The aircraft is made from bonded and pop riveted aluminum sheet and has a 261NaN1 span wing. Optimized for simplicity of construction, the design has no compound curves and requires no jigs or special tools. The standard engine intended to be supplied with the kit was the 550NaN0 two-stroke Hirth 2702 powerplant with a reduction gearbox that allowed the propeller to operate at lower tip speeds. This engine permits the EOS 001 to cruise at 1870NaN0 and achieve a top level speed of 2000NaN0. The prototype was equipped with a Volkswagen air-cooled engine.[3]
The aircraft has an empty weight of 320lb and a gross weight of 750lb, giving a useful load of 430lb. With full fuel of the payload is 310lb.
In 1978 the claimed completion cost was US$2,000, not counting labor.
The prototype EOS 001 was registered in the United States with the Federal Aviation Administration (FAA) in 1978.
By October 2013 two examples, including the prototype, had been at one time registered in the United States with the FAA, but both registrations were later canceled and it is likely that no examples of this type exist today.[4]
