Why not hybrid? Have an onboard gas generator to recharge the batteries. As soon as the gas runs out, the drone has X min of battery flight time left to get back to solid ground. No need for mechanical complexity.

- bri3d 11y agoThere's an MIT spinoff called Top Flight that was working on a hybrid quadcopter, IIRC. I think the main reason you don't see them in the hobbyist space is size floor (you need a pretty big machine to make the weight overhead of the motor, generator, and charge circuitry work out) and money.
