10/31/2011. Remarks by Walter van Tilborg: "The P-180S design of Jean Pottier was a two-seat development of the low-wing P-80S, but, unlike the parallel developed tandem two-seat P-170S, featured side-by-side seating.
The first aircraft of the type was built in France by Gérard Beauchet and temporarily registered F-WYKT (c/n 012) it was first flown on June 18, 1977, being reregistered F-PYKT on October 19, 1977. It was powered by an 100 hp Continental O-200-A engine, and was soon followed by further aircraft often with modifications and VW or VW based engines in the 65 to 115 hp range. The pictured F-PYZL was built by Jean Pottier and first registered on August 26, 1998.
The sole PRM-180 was a much modified aircraft built by Roquette and Jean-Francois Mille and first flew in May 1985. It had a lower rear upper fuselage decking and was also fitted with an O-200-A engine."
