Propellers for electric flight need to be lighter than those used for internal combustion engines; electric motors do not need the flywheel effect of a heavy propeller. Also, lightweight propeller will accelerate to speed more quickly.

Folding propellers are highly desirable for electric gliders. We use a speed controller with a brake, so that the propeller will stop spinning when the motor is shut down, and the blades will fold. Even for continuous running, special propellers are required. Here is a selection of blades, propellers and hardware made especially for electric flight purposes:
