Each propeller assembly is made up of the propeller blade, gear, motor and motor controller board.

These are not your run-of-the-mill propellers. The design team behind these won a micro drone design contest put on by the French Army.

The propellers spin in different directions depending on the side they are mounted on, and are marked either C (clockwise) or A (anti-clockwise).
