The aircraft is a Comp Air 7 with its fuselage stretched by 2 feet (0.6 m) to accommodate six adults and two children. The Comp Air 8 is configured as a conventional high-wing monoplane with optional tailwheel or tricycle undercarriage. It can be fitted with large floats for water operations.

The Comp Air 8 fuselage and tail are constructed with carbon fiber. Fuel capacity can be determined by the builder and can be as much as 180 U.S. gallons (680 L; 150 imp gal). The useful load is 2,000 to 2,500 lb (907 to 1,134 kg) and the aircraft has a standard gross weight of 4,800 lb (2,177 kg). The gross weight can be increased to 5,200 lb (2,359 kg) or even 5,600 lb (2,540 kg) with factory-supplied reinforcing kits. The standard engine used is the Walter M 601D of 657 hp (490 kW)

Kit production seems to have ended in 2021.
