The motor rotation direction can be 
determined by the color of the wire 
leads. The clockwise motors have black 
and white leads. The counter-clockwise 
motors have red and blue leads.

1. Refer to the propeller rotation 

diagram in the Replacing the Pro-
pellers section. Determine which 
motor needs to be replaced and 
which direction it rotates.

2. Unplug the motor wire from the 

4-in-1 board.

3. Using your thumbs, carefully spread the base of the motor pod apart while pushing the motor downward out of the 

pod as shown.

4. Slide the new motor into the pod until it is captured by the bottom of the motor pod.
5. Route the wire lead through the arm of the frame and plug the connector into the 4-in-1 board. Make sure to clip the 

wire into the frame arm to keep the wire from interfering with the spinning propeller.
