Around 1960 this company manufactured an engine for which they made approval tests in front of representatives of Civil Aviation and Bureau Veritas in Buc, near Paris.

-It was intended to replace the American Continental 65 CV, 90 CV and 100 CV engines for French light aviation.

-The Chabay 4C-10 model that gave 110 hp had an almost identical lay out to a Lycoming, with four horizontally opposed cylinders and also the generator, starter system and crown wheel were similar to the engines that it attempted to replace.

"Chabay"

-Little is known about the outcome and successful implementation since there are no reviews of them on Piper Cub, Robin DR-100, and Rallye MS-880 aircraft for which they were intended.

“4 Chabay views”

-The dimensions are almost identical to those of Continental O-200 and Lycoming O-235 and O-290.

-The industrial firm Puteaux would give momentum to the Chabay engine trade.

-Curiously, dynamo and starter were from the Peugeot 403.

-They also tried it to be an alternative for small Potez engines, (see).
