Dear help! I bought n31 and it falls for an unclear reason. Motors stop working and do not react to the stick before falling. This occurs at different distances (5, 10.15 meters) and heights (2, 5, 10, 15 meters) further and higher has not flown. Batteries drone changed and batteries in the remote, too. I noticed that if the drop height is enough, then by moving the gas stick down and down (as when the drone is turned on before the flight), the engines start working reacting to the gas stick. I suppose that the connection between the console and the drone is lost, but why?

Arturixanything from marriage to magnetic storms. Check all connections for contact quality, plus inspect the board in the console and in the quadric - there may be poor-quality soldering somewhere, the power buttons may not work well. Again, the antenna in the console is just a track on the board, and in a quadric it is a piece of wire and how these antennas are positioned relative to each other also matters. Although I was outside the city of my green right above me raised up until it turned into a cross. With a 200mW camera, it flew 40 meters into the distance and upwards to 15-20 meters. And on the site near the house could fall and 10 meters.

Thank you, I will look for bad contacts, as you said, and I hope they will be seen in the photo. I bought it on Ali, and in order to open a dispute we need evidence of why he is falling. I won’t find it myself, I’ll carry it to the workshop - I have to repair it for any child. Radish is sold - 2 batteries out of 5 did not report so the drone falling down slipped ...

With a 200mW camera, it flew about 40 meters into the distance and up to 15-20 meters up. And on the site near the house could fall and 10 meters.

-thorn-,
Hello. Here from this place is more detailed, please. I came quad, without a camera - everything is fine, the connection keeps excellent, as soon as I cut down the Wi-Fi camera - the loss of communication with the console begins. Tried so far only on the site and in the apartment. In both cases, the connection is randomly lost. Those. could it be a marriage? Is there not enough room for him? The reflected signal interferes there, or something else? But why is it only with the camera? Or is the cutoff happening? ...

Scion,the frequency of the console and Wi-Fi in the same range ~ 2.4GHz, so that this behavior is quite normal. I took the camera

and helmet

This camera, or rather the transmitter on it, has a completely different frequency range and there is no conflict with the remote control.

[Scion]

-thorn-,flashed such a thought, thanks for the clarification. Replacing the antenna in the console with a normal one from the router will not help, as I understand it? Or a more powerful signal can solve the problem?

[-thorn-]

Scion,I do not know about the replacement of the antenna. When I put the camera, I already played enough with this quadric and collected more serious. It’s just that the camera and the helmet came before everything else, so I took this case by the 31st — just to see how it is.
