4x 402" to be specific. Fantastic technical achievement

Which one of these should I use if I want to fit 10185mm rotors to my bike?

And more importantly would it take off if it was on a Lazy Susan?

I can't see how it works. How is the force from the pedals being transferred to the rotor blades?

It'll never take off 🙂

What tyres for 402?
lack of good rubber may spell thre end of the project.

@shermer75. Looks to me like there are spools attached to the cranks that are 'winding in' some kind of cable from each rotor to make them spin, so a finite flight time I guess.

Still quite a cool thing.

Stunning! A beautiful piece of engineering, but I would imagine the flight time is finite purely because the 'pilot' is going to be a physical wreck after ten minutes of pedalling that thing! And how the hell d'you steer it?

Is the back wheel integral to the stability? Like rear rotor on "standard" helicopter?
Otherwise they could lose a tiny bit more weight by getting rid of it and the rear stays.

Probably acts more like a flywheel and helps smooth and regular the peddling effort a bit

Ah, I see. Stunning bit of kit!
