Ensuring the correct rotation of your FPV drone's  BLDC motor is crucial for successful flights. You can modify the motor's direction through hardware adjustments involving wiring changes between the motor and ESC, or by making software modifications within the ESC or flight controller.

Diverse Rotational Directions for FPV Motors:

FPV motors can rotate either clockwise (CW) or counterclockwise (CCW), affecting the propeller rotation, known as "Props-out" or "Props-in." Most firmware defaults to "Props-in."

"Props-out":

This configuration is beneficial for smaller drones, especially those under 3 inches, offering aerodynamic advantages, particularly during sharp turns. "Props-out" rotation helps protect the FPV camera from debris during crashes by throwing debris away from the craft.

"Props-in":

"Props-in" rotation generates more turbulence during yaw rotation, simulating a sudden 90° turn. Some whoop drones have addressed this by switching to a reverse ("Props-out") rotation.

Changing FPV Motor Direction in Betaflight:

Remove propellers, connect the LiPo battery, and access the "Motors" tab in Betaflight. Use the "Wizard" and "Start/Spin Motors" options to adjust and confirm motor rotation direction.

Changing FPV Motor Direction by Rewiring:

For a hardware solution, swap any two of the three motor wires, necessitating desoldering and resoldering them back to the ESC.

Using BLHeliSuite for Motor Direction:

If soldering isn't preferred, BLHeliSuite software offers an alternative. Connect your quadcopter to your PC, access the ESC via BLHeliSuite, and change the motor direction from "Normal" to "Reverse" or vice versa.

Conclusion:

Adapting FPV motor rotation is crucial for optimizing drone performance. Hardware or software adjustments provide flexibility across various FPV drone builds, accommodating different ESCs, flight controllers, and software setups.
