Pull the throttle trigger with the motor shaft faces you, the motor spins counter clockwise if this item is set to CCW; the motor spins clockwise if set to CW. The (A/B/C) wiring order of motors from different manufacturers may vary, so the direction of the motor rotation may be opposite to what you expect. You can adjust the “Motor Rotation” or swap any two (ESC-to-motor) wires if the motor runs in reverse.
