Please find a link to a 3rd party article describing the rotation direction of the propellers:
A quick tip:
- CW (Clockwise) goes to Left Front arm and Right Rear arm.
-CCW (Counter Clockwise) goes to Right Front arm and Left Rear arm.
Here the "Front" means the power button end of the PowerEgg and the "Left" and "Right" are defined as you would be standing behind the drone, facing the same direction as the PowerEgg.
Hope it helps :)
