This is bit of a duplicate question. [Reference this question](https://drones.stackexchange.com/questions/93/what-process-should-i-use-to-ensure-my-motors-are-spinning-the-correct-direction/133#133) for a complete answer.

@QuadMcFly My thought was more towards someone who was building a model aircraft. An RC plane is less likely to have a flight controller board or anything to do with Betaflight. Maybe the subsection of "Physically Change the Wires" could link to this question for details on why switching any two wires works?

I have a brushless motor on my RC plane. After connecting it to an ESC and testing it I've found that it is spinning in the wrong direction.

How can I reverse the direction the prop is spinning?

Swapping any two of the wires connecting a brushless DC motor to its ESC will reverse the direction it spins.

Despite the name BLDC which implies that the motor runs on DC power, each of the three wires (*connected to one of the three phases in the motor*) is driven by the ESC with a phase-shifted AC waveform. Each wire's waveform is shifted by 120 degrees from the other two.

This offset is what allows the swapping of two wires to reverse the direction of the motor's rotation.

Because nothing special is required to reverse the motor direction, it is also possible to fix this by editing the software configuration, which will do the same thing but in software. *e.g. in the BLHELI32SUITE software for ESCs with the BLHELI\_32 firmware installed*

Swap any two of the wires between the ESC and the motor. Alternatively, use the configurator on your computer for whatever firmware your ESC runs and switch the direction via the software.

For example, if it is a BLHeli\_32 ESC, you can go to the BLHeli\_32 Suite and reverse the motor direction from there.
