This bizarre design was made pubic in the April 1939 edition of the French Aviation magazine and there was some doubt if it was an 'April Fool'. Wind tunnel tests with scale models revealed that the design was seriously unstable and the project was abandoned in June of the same year.
Modern design techniques might be able to produce a flyable microlight with this configuration (I have my doubts) but the 1939 design appears to have been built around a powerful v12 engine.
Because this aircraft is so small I am only making it available as a sprue of 4 models. The spherical recess underneath the model is intended for mounting it on a 4.5mm BB.
