There's a way to spin each propeller at 180 degree phase so they would cancel/reduce each others noise.

- danieltiIlett 11y agoHow difficult is it to do while adjusting each propeller's speed for steering etc?
- petra 11y agoI've only heard about for wing based uav's , not quadcopters. Maybe this is a good sign for Google's drones, which use wings, but rotate their rotors for landing.
