3.12. Installing Propellers
Locate the correct propeller for each motor. As seen in the photo below, three of the
IF1200’s motors will spin clockwise, and three will spin counterclockwise. The two motor
and prop types have keyed quick-disconnects that prevent a user from mounting the
wrong propeller on the wrong motor.
The clockwise quick disconnects have three notches, while the counterclockwise motors
have two. A counterclockwise motor with two notches can be seen below.
