## 3.3.1  Replacing propellers

[PDF page 48, block 11](https://shop.skyflow.ca/learn/autel/evo-lite-enterprise/manuals/evo-lite-640t-v1-0-2/3-3-propeller#p48-b11)

The propellers are installed in the aircraft by default at the factory, and reinstallation is not required. If the propellers are damaged (such as broken or damaged propeller blades), please replace them with new ones before a flight.

## Installing the Propellers

[PDF page 49, block 2](https://shop.skyflow.ca/learn/autel/evo-lite-enterprise/manuals/evo-lite-640t-v1-0-2/3-3-propeller#p49-b2)

When installing the propellers, strictly follow the following instructions:

[PDF page 49, block 3](https://shop.skyflow.ca/learn/autel/evo-lite-enterprise/manuals/evo-lite-640t-v1-0-2/3-3-propeller#p49-b3)

1. Make sure that the aircraft is powered off before installing the propellers.

[PDF page 49, block 4](https://shop.skyflow.ca/learn/autel/evo-lite-enterprise/manuals/evo-lite-640t-v1-0-2/3-3-propeller#p49-b4)

2. The aircraft needs to be installed with two models of propellers, that is, CW and CCW, with two of each model. The CCW propellers have a white circle mark at the center shaft, while the CW propellers do not have this mark at the center shaft.

3. There are two types of propeller mounts on the front and rear arms of the aircraft. The mounts with a white circle mark at the center shaft are for CCW propellers, while the mounts without this mark are for CW propellers.

4. Place a propeller on the corresponding propeller mount. Make sure that the buckle at the center shaft of the propeller aligns with the slot on the mount. Hold the motor on the arm below the propeller to prevent it from rotating, press down on the propeller center shaft firmly, and then turn it in the locking direction marked on the center shaft to secure the propeller in place.
