M5 Set of 2 Propeller Nut Cap CW CCW For Brushless DC Motor

The M5 Set of 2 Propeller Nut Caps includes one CW (clockwise) and one CCW (counterclockwise) cap designed for 1306 and 3100 brushless motors to be fitted above the propeller. These nut caps are commonly differentiated by color, such as black and silver, for ease of use.

Understanding the distinction between CW and CCW motors is crucial in the quadcopter hobby. Despite being essentially the same motors, CW and CCW motors differ in the direction of their prop shaft threads. For example, a CCW motor has prop shaft threads that tighten clockwise, while for a CW motor, the threads tighten anti-clockwise.

The key advantage of having different threads for CW and CCW motors is referred to as ‘Self-locking.’ In a quadcopter setup where two motors spin clockwise and two spin counterclockwise, using threads opposite to the motor spin direction ensures that the prop nuts automatically lock themselves down, preventing them from coming loose during flight.

However, this design choice can lead to challenges in sourcing spare prop nuts for both threads and can cause confusion when determining which way to turn to remove the prop nuts during propeller changes.

Practically, if you can fasten the prop nut clockwise, you have a CCW motor, and you should use the Right-handed thread nut (standard thread). For CW motors, opt for the Left-hand thread nuts (reverse thread).

While this setup may introduce some complexity, it provides the benefit of self-locking prop nuts, ensuring a more secure and reliable connection during quadcopter operation.
