Propeller maintenance

The propeller is also one of the fast-moving equipment for drones , especially for novices, so you should pay more attention. Although in normal use, there is not much chance that the drone will fall off the blade, but the tree hit due to visual error or improper manipulation frequently occurs.

Before the drone takes off, it is necessary to check whether the blade has cracks or gaps and directly affect the flight stability. If the damage is serious, it is best to replace the new propeller directly.

In addition, pay special attention to whether the propellers are fixed in order before take-off.
