Learn the most common reasons why your drone propellers are not working correctly and what you can do in all of those cases.
If your drone propellers do not rotate properly or are not powered at all, you will need to postpone the next flight until you are sure that the device is in good working condition. If you want to solve this problem and continue to use your drone, it is good to know what to do in such cases.
Some of the most common reasons why the drone propellers do not work properly are obstruction of various materials, battery problems, unstable connection or lack of control, improper installation of the gyroscope, problems with propellers, motors, and suspension of the drone.
We will go through all possible causes of the damage and what you can do when the propellers are not working properly.
1. Inspect the device for visible debris
Always start the inspection from the outside. The first thing you need to do is see if there is any waste or debris that prevents the propellers from working. Sometimes objects can be so small that they are not visible at first sight. If you notice any, remove them and try to take off again.
2. Check the batteries
The next step, if the propellers are not even spinning, you should check if the batteries are charged. If the charger is not working properly, you may not be able to charge the batteries to their full capacity.
Insufficient battery charge can cause the propellers not to rotate as they should or not to spin at all. This is because the device does not have enough power to activate all parts of the drone. Note if the drone lights are flashing in a way that shows a low battery charge.
If the battery life has expired, it may lose charge very quickly or not charge at all. In such cases, it is important to have spare batteries to replace the old ones.
3. Check the transmission connection
There are two reasons related to the connection to the controller, due to which the propellers of the drone may not be spinning. The first one is a lack of synchronization with the remote controller according to the manufacturer's instructions. If you have not synchronized the controller and the drone, it is very likely that the drone motors will not work, and this is also related to the rotation of the propellers.
The other reason is the lack of charge of the controller's batteries. In the absence of enough power, you may not be able to synchronize the drone with the controller. In this case, just charge the batteries.
4. Check the initialization of the gyroscope
The correct initialization of the gyroscope triggers the start of the propellers. Checking of a proper initialization should be done on a flat surface, leaving the drone stationary for about 10 seconds. After that, you need to read the drone manual, where it‘s described how to continue the verification process. If you do not find this information, contact a specialist to advise you what to do.
5. Check the propellers
There are several reasons why you may have problems with the propellers that prevent their movement. The most common is - incorrect installation. If the propellers are too loose or tight, this will most likely interfere with the motor and, hence, the propellers' rotation.
Keep in mind that even the slightest damage or cracks to the propellers can lead to flight problems such as vibration and loss of control of the device. Always have spare drone propellers on hand to replace the old ones if needed. It is better to make a small investment and replace the old propellers with new and reliable ones than to deal with the accident's damage.
6. Check for external and internal damaged wires
During a flight, the wires can rupture without you even realizing it. There are cases in which the damage is not noticeable, as part of the wiring is not visible.
As it is difficult to identify this damage and perform the repair yourself, it is best to take advantage of your drone's warranty and contact a drone service.
7. Check the functions of the bikes
The motor must run smoothly so that the propellers can rotate. Small objects or hairs may be stuck in them, which you must remove very carefully with tweezers, after removing the propellers first.
If the drone has crashed, the motors will likely turn off and the propellers will stop rotating. In such cases, it is best to contact a professional drone technician and avoid voiding the device warranty in trying to repair the drone yourself.
8. Check if the motors are damaged
If you have done all the checks mentioned so far and the propellers are not spinning, the motors may be damaged. They likely need to be repaired or completely replaced with new ones.
The causes of motor damage may be broken supports, wetting damage, faulty bearings, and bent shafts. You can recognize that you have a problem with the motor if you lose control and power during the flight if you notice vibrating during the flight or issues with the propellers' rotation.
There may be many reasons for the incorrect rotation of the propellers or the drone's failure at all. But whatever the reason, make sure you follow these steps and the manufacturer's instructions. When you are not sure what you are doing, it is best to contact a drone service to ensure that the device is repaired properly and you can continue using it hassle-free.
