Hello, I have never made a post before since I have always been able to find my answer lurking and viewing other peoples problems but this one is stumping me so that is why I am posting. I had a 5 inch quad and then sold it and then built a 7 inch.
The problems began about a year ago where my 7 in. quad would drop out of the air and random intervals.
Over time, as I flew the quad more often it would drop out of the air more and more. I eventually did a hover test and the quad would just drop in the hover test. I figured this was the esc dying so I then bought a new esc. I have installed the new esc (Diatone Mamba F60) and now the quad goes in the air and does not drop which is good! But now I have a new problem that is stumping me. If I punch the throttle a little too fast, the quad will start spinning uncontrollably in an anticlockwise motion until I hit the kill switch. I can raise the throttle slowly and it is fine, but a little too fast and it will start spinning. I checked the logs and tried to adjust the Pids to no avail. I checked that all the motor connections are good. All the motors spin super nice and dont seem broken. I read about esc desync but I was unsure of how to diagnose it or address the issue. I dont know why but I have a feeling that my problem is with pids and filtering rather than desync. I was wondering if someone has any idea what is going on. Below I will list specs
The pids attached are my most recent pids and only apply to the most recent blackbox (blackbox 6) since I was messing with the pids a lot. The problem though is persistent through all of the logs though where I have to kill switch the quad.
Not an expert here but a few things that I noticed:
Why motor 3 is lagging behind all other motors at the start of the flight? If you look at the log all other motors are spinning and motor 3 is not.
Doubt is your filters and tuning it looks like you are to the stock levels and those work fine and should not make drones spin in most of the cases
