Piel Zephir Explained

The Piel CP.80 Zephir (or Zef), Piel CP.801 and Piel CP.802 are racing aircraft developed in France in the 1970s and marketed for homebuilding.[1] They are compact, single-seat, single-engine monoplanes with low, cantilever wings.[2] [3]

Design and development

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]
