Check if your motors are spinning the correct direction

If you are building a new quadcopter, you have to make sure the motors are spinning the correct direction before putting propellers on for your first flight. If one or multiple motors are spinning the wrong direction, the quad will flip over at take off.

This is the default motor spin directions in Betaflight:

If the motor spin direction is wrong, you can easily change it by using one of the following methods.

Swap two of the motor wires

By swapping ANY 2 out of 3 motor wires to the ESC, you can easily reverse the rotation direction of the motor. Doesn’t matter which two, the result would be the same.

Reverse motor direction in BLHeliSuite software

If you don’t like soldering, you can also easily change motor direction in the BLHeliSuite program (if you are using BLHeli ESC’s). This program is the configurator for your ESC that allows you to change many different settings, including motor spin direction.

Motor Direction should be set to “Normal” by default, you can change it to “Reverse” if you want the motor to spin the other direction. You also have the option to set it to “3D”, which will allow you motor to spin both directions for 3D acro flying, don’t use it unless you know what you are doing.
