It may be helpful to secure each arm
in place temporarily with a metal nut.
3 Label motors
Use tape (or other method) to label
the motors by the numbers shown
here.
4 Connect ESC and motor cables
Connect the motor cables to the
corresponding ESC cables according
to the labelled numbers (connect
motor 1 to ESC 1, motor 2 to ESC 2,
etc). The order of the three cables
determines which direction the
motors will spin and is critical for the
copter to fly correctly. The diagram
above shows which motors need to
spin clockwise (CW) and counter-
clockwise (CCW).
The images below show the correct wiring to produce each direction of rotation. The motor
cables are differentiated by color. To differentiate the ESC cables, orient the ESC with the
label facing up, and use the relation of the cables to the label.

center = red
bottom = black
