The Piel CP.500 was a light aircraft of unusual configuration designed in France[1] in the 1970s with the intention of marketing it for homebuilding.
It was a tandem wing design,[3][4] somewhat reminiscent of the Mignet Pou-du-Ciel but considerably larger.
[2] The rear wing was also to carry endplate-style fins and rudders.
[2] Twin engines were to be mounted in push-pull fashion at the nose and tail ends of the fuselage, with the aircraft capable of single-engine operation in case of emergency.
However, as development progressed, Piel considered metal as the main construction material.
