Is storing energy against the rules? for example pedaling for an hour or two to store up say mechanical energy in a flywheel, spring tension, hydraulic pressure or other means then just put the rotors in gear to lift off?

I have to assume so. Leverage is presumably allowable though.

Once you're in the business of storing mechanical energy, you haven't solved the problem of sustained human-powered flight and you're really just a technology epoch away from using a motor and a capacitor.
