[1] The F.80 was intended to compete against the Hanriot HD-14 as a basic trainer.
It was an equal span two-bay tractor biplane with tandem open cockpits for instructor and pupil.
It had a tailskid landing gear with the two main units widely spaced for stability on the ground.
The aircraft also had a pair of auxiliary wheels in front to prevent the aircraft nosing-over on the ground and damaging what was then an expensive wooden propeller.
[1] The aircraft did not meet with any success and was not ordered into production.
