This contraption may not look very impressive…
But when the bicycle-powered helicopter defied gravity, it caused great excitement.
Its flight only lasted 64 seconds and reached an altitude of 3.3 metres. Though it was a great achievement for the Canadian team, which spent 18 months designing the chopper.
They won a prize worth $250,000 from the American Helicopter Society.
The team hope to inspire the next generation of aviation pioneers.
