INSTALLING THE PROPELLERS
With the drone powered off, hold the base of the engine
and screw the propellers on the Parrot Bluegrass motors.
The Parrot Bluegrass uses two types of propellers: plain black
ones (front left and back right, screw clockwise) and white-
dotted ones (front right and back left, screw anticlockwise).
Refer to figures A and B to make sure you respect the propellers'
respective positions.
