10/31/2011. Remarks by Walter van Tilborg: "The low wing single-seat all-metal P.80S sport aircraft was derived from the mid-wing all-metal P.70S with unchanged overall dimensions and structures, but had a restyled cockpit hood, and could be powered by VW engines in the 40 to 60 hp range. It was available with a tail wheel or a tricycle undercarriage and examples were built in France and several other countries, including the Netherlands.
Design began in January 1977 and the aircraft was constructed by members of the French RSA (Réseau du Sport de l'Air, homebuilders organization) during and at the Paris Air Show (June 3 to 12, 1977) and the aircraft was unveiled on the last day of the show. Initially allotted the test registration F-WYEB, the aircraft became F-PYEB on August 23, 1978, after it received its CofA.
Other known designations for French-built aircraft are P.80SM, which was an aircraft with a tail wheel undercarriage and a 60 to 70 hp VW2000 engine, the P.80SR with an 100 hp Rolls-Royce/Continental O-200-A and a tail wheel undercarriage built by J. Radieux and flown in August 1984, and the P.80SMR built by Alain Rougetet, that was registered F-PALA on July 4, 2006 and certified the same year.
The pictured aircraft was built in the Netherlands under the NVAV project number 42, and was registered as PH-SOM on November 9, 1982. Three years later, December 3, 1985, the registration cancelled as the aircraft was sold to Belgium, where it since is registered as OO-54."
