Design and development edit
The pilots sit in fully enclosed cockpits and the tailwheel undercarriages are fixed.[2][3][4] Although designed to be built of wood,[3] the first CP.80 to fly (registered F-PTXL and named Zef) was built from composite materials by Pierre Calvel and beat even the designer's own CP.80 into the air.[2] Calvel's CP-80 was entered in the French Formula One air races in 1976, but failed to qualify.[5]
