If a VEX AIR Drone begins flying unevenly, vibrating, or losing lift, it may be due to damaged or dirty propellers. Over time, propellers can collect debris like hair or string, or suffer from chips and dings that affect flight performance. This guide explains how to remove and install propellers so they can be cleaned or replaced.
Important: Make sure the drone is powered off and the battery is removed before removing or installing a propeller.
Removing a Propeller
While bracing the propeller, unscrew the two screws located underneath it.
Once the screws are removed, the propeller can be removed.
Important: Always remove the propeller by lifting directly upward. Pulling at an angle may damage the motor or propeller shaft.
Cleaning or Replacing a Propeller
Over time, hair, string, or other debris may become wrapped around the base of the propellers. To remove this buildup, use tweezers or a soft brush to carefully clear any material from the propeller shaft or base.
If a propeller shows signs of damage, it may need to be replaced. Indicators of damage include:
- Edges that are chipped or dented
- Visible cracks or stress marks
- Blades that are bent or warped
- Unusual vibrations during flight
Installing a Propeller
Before installing the propeller onto the motor’s pin, make sure the blades are oriented correctly. The arrow on the propeller should point in the same direction as the arrow on the drone.
To install a propeller, position it on the propeller motor’s pin, making sure the mounting holes line up correctly.
Insert the screws into the mounting holes and tighten them.
The screws are fully secured when the propeller begins to turn along with the screwdriver.
