But the best way to determine the value of min_throttle is to individually spin each motor in the motor tab. Take note of all the values at which the motor spins smoothly. Of all the motor, take the highest value and add 5-10 to it. Example if you values were 1010, 1030, 1025, 1015, then take 1030 (highest) add 10 equals 1040. Make that value min_throttle. This makes sure all your motors spin up when you push on the throttle.
The problem is that I want them to spin up in less speed, in order not to take off by itself at idle. Edit: Decrease the min_throtte without desynchronization

I reset to the Betaflight settings. I ARMed the quad - no issues. I performed a test flight - no issues.
I will let you check the differences, between the problematic tuning that caused lift off after ARM and the reset settings (default Betaflight) that were ok.
This is an excel file that I have created for such situations. I hope you find it useful. I am all ears for your opinion on this.
The thing I find significant is your D terms were all very high in the bad tune. D term usually amplify noise, hence D term has a filter. The noise likely is causing your bounce on ARM.

Many thanks Voodo!!! Really appreciate that! I will be more careful next time with PIDs

lol I only said it once, I thought the same thing as snow I didn't realize he wasn't using Dshot

If you switch the protocol, you will see the settings that are relevant.
I seem to recall we had this discussion before about using DSHOT on your PowerCube before, but I can't remember what the outcome was and I can't find the conversation.
The PowerCube uses BLHeli_S ESCs which will support DSHOT as long as you have a recent version of the BLHeli_S firmware installed. I therefore suggest you make sure the ESCs are on the latest version of BLHeli_S which is 16.7. If they're not then just flash that newest version to them. Then you can use DSHOT.

I have the version 2.0. At least we did no have this specific conversation on ESC's protocol. If I remember well I have flashed F-H-0 16.7. I will check it how I can use DShot

The PowerCube BLHeli_S ESCs support up to DSHOT600 so use that. If you're on Betaflight 4.1.x, DSHOT600 is the highest you can use anyway (support for DSHOT1200 was dropped).
Easiest way to tell if an ESC protocol works is a bench test. Props off. Switch to the protocol you want eg Dshot. Go to motor tab and spin the motors.
