There is a video at the bottom of the page going through the process of replacing a propeller on Arrowhead

</aside>

Arrowheads aircraft propellers can get chipped, worn out, and damaged during the standard service life of the aircraft. Proper maintenance of these propellers are critical for ensuring reliable performance and handling. Flying with damaged propellers can cause damage to other aircraft systems like the ESCs as well as the motors themselves. Chipped props can also pose a safety hazard as the prop could break apart in flight causing unpredictable flight characteristics.

Required tools

• 1x Propeller nut driver

  

• 1x Propeller set (it’s good practice to change the full set so that all propellers will have the same performance)

  

Keep in mind the direction of the motor when changing the propellers, the below diagram shows how the motors spin in standard operation. Ensure that the airfoil of the propeller matches its correct direction of spin. The easiest way to do this is to reference the propeller that is damaged and match that.

Operation

1. Holding the motor with your fingers, use the prop nut driver to remove the prop nut.

Be careful as props have sharp edges!

1. Remove the damaged propeller. The tolerance can be tight, if needed you can wiggle the propeller back and forth to remove it. Keep the propeller for the moment as a reference for the replacement propeller.
2. Using the reference propeller, select the appropriate replacement propeller and slide it on the shaft until it makes contact with the motor bell.

1. Holding the motor with your fingers, use the prop nut driver to secure the nut on the motor. Tighten the propeller down until the propeller cannot be spun independent of the motor.
