The problem is exactly what I first was looking at, you have a ground rise issue caused by the length of your power lines to your ESCs
Mix this with ESCs that are not 3.3v compatible and you will get this issue.
This is a known limitation of many cheap ESC’s, especially those that have the ATMEGA8A processor onboard as it has a known issue with its signal levels being at 2.4v rather than the correct 1.4v for “high” TTL levels.
The “solution” is either to change your ESCs, or use 5V signalling
For 5v signalling we have two options…
The green cube
The orange cube
The orange has a software switch to select voltage level on the PWM lines.
The Green cube has only 5V signalling.
The recommendations for you is both fix the ESC, and change to the orange cube.
Thanks @philip, I really apreciatte your and the comunity help.
To avoid this problem again, can you tell me how to check where I can find the 3.3V compatible and about the processor? Im checking the ESC specs and I cant find that information. In fact, I thought the ESC has ARM processor, not ATMega.
In the other hand, can you recomend me a ESC for this kind of motor? 4010 340-380kv 6s, may be a very small one? BLH or OPTO?
I have installed a new ESC and a motor over my benchtest, conected to a cube, try the motor test and TH from the remote, and no problem. I have put a very large signal and power cable to the ESC and still ok.
So I tought, ok, maybe is the ESC from the drone or the motor has problem, but before to take all the dron a part to take the motor and ESC out, I tought to connect one of the motors of the drone directly to the cube on the bench. and this is what happend.
As you can see, if I use the cube from the bench, no problem.
I already change the cube and the carrier once by the way.
The last test was installing the cube of the bench on the drone, and again, the same problem, i think must be something related with the cube power source, its a Mauch Enectronics, this is it
I already think the drone is hunted…
Now Im going to check the power source of the Cube inside the drone, its from Mauch Electronics, it suppose to be one of the best for the drones.
I made the same test with my “good” drone (same ESC, same FC, same cables, etc), and if I do the motor test give me the same results. That drone flew almost 4 hours las fryday, and no cliping or trouble.
Here is one of the logs of that day, almost 44min flight, @philip can you give a quick check and see if was a normal flight? I have checked and didnt found nothing strange.
…I saw its a switch on the carrier to change the PWM voltage.
I dont have that carrier, I have the Mini Carrier Board and airbot carrier. I was looking at to see it those have a kind of jumper to change the voltaje, and I found this:
