It's more than likely your kiss fc. I've had two kiss fc's with the exact same issues you're experiencing. Tried new motors, esc's and a new freaking pdb but the only fix was ditching the kiss fc. My friend re flashed one of them but it still wouldn't work. When I would throttle up on the bench my motor signals on the kiss gui would be all over the place. I'd be at let's say 20% throttle on my transmitter but on the kiss gui it would show two or 3 or all 4 motors throttling up way past 20% on their own. I switched to the sp racing f3 flight controllers running the exact same gear as I did with the kiss fc and I had absolutely no issues.

I have to agree. Everything else that I can think of that would cause this has pretty much been eliminated.
Edit: you might try flashing betaflight to it, my friend usues a Kiss with it and it works great. I personally use an SP Racing F3 also, and highly recommend it as well.
