Morning Joe,
My "American Classic" is a Big Guff. The model was designed by Dr Walt Good and it won the American Radio Controlled National Championships in 1938-1940. His twin brother, Bill Good, designed the radio.
As for the "Coupes," please let me clear up a mis-understanding. If you were referring to the models pictured below, they are called Barons. The Baron was designed by Christian Chauzit in the late Sixties or early Seventies and is as much a classic trainer in France as the Sig Kadett is in America or the Super 60 in Great Britain. Une Coupe in French means a cup so La Coupe Des Barons means "The Barons' Cup," a light-hearted competition held every year in the south-east of France. There is a plan for the Baron on the Outerzone but the model has been cleaned up and ailerons added. Another source of plans may be AeroFred but I have never used their service. Ailerons are banned in the competition, the original model was three channel and powered by a 15-19 motor but you can use anything up to a 35 two-stroke or a 52 four-stroke in La Coupe.

The Big Guff plan is also available on The Outerzone
