The quadcopter does not respond to the remote control: What to do in such situations and how to fix it

If the quadcopter does not respond to the remote control, this indicates a complete loss of communication. Most likely, the reason is due to insufficient charge level or battery failure. A more complex option is a breakdown of the control panel. The most common cases and solutions are described in this article.

Remote control failure

If the quadcopter does not see the remote control, the reason may be due to mechanical failures. They arise due to a fall, an object, natural wear and tear over time, drops of water, or burnout of contacts.

As a result of the influence of the mentioned factors, the remote control board, that is, the main microcircuit that controls all processes, may suffer. In this case, there is no way to fix the quadcopter yourself. Essentially, you need to change the board, and this can only be done with the appropriate skills.

In addition, a malfunction can only be diagnosed if you have the tools - a multimeter and an oscilloscope. In such cases, it is better to contact an experienced specialist or purchase a new remote control.

Battery fault

If the quadcopter completely stops responding to commands, the reason may lie in the battery. The simplest case is when the battery is not charged. You should check the level and put the device on charge.

It is worth noting that many devices have built-in batteries.They can only be charged when the device is turned off. Moreover, they are plugged into the outlet for only 1.5-2 hours. It is not recommended to leave it on charge for a long time, for example, all night.

If the battery does not charge at all, this indicates a failure of the battery itself or the contacts. For example, they could oxidize due to the ingress of water particles. In this case, you need to “ring” them with a multimeter and, if there is no resistance, resolder them or install a new battery.

Other reasons

It also happens that the aircraft responds to commands, but not entirely correctly. For example, it is not clear why the quadcopter pulls to the side, takes a long time to gain altitude, or sharply descends. In such cases, you should not look for the reason in the remote control. Since there is contact, the connection is normal.

But the fact that the device flies with obvious deviations indicates a malfunction of the propellers. It is recommended to conduct a visual inspection to look for breakdowns in the mechanism or the propellers themselves. If this is not possible, you will again have to contact a professional.

Thus, the complete lack of response of the quadcopter to the remote control indicates a battery failure or mechanical damage. The simplest case is when the battery is just low. In other situations, most likely, it will not be possible to determine the cause and eliminate it on your own.
