When you say "increasing min throttle up to 1100" do you mean min throttle? Or the equivalent of digital idle which would be 10 i think?

Not that it matters since you tested multishot too.

Exactly. I stopped at 7 when using dshot and changed to multishot instead and increased it untill I reached 1100. Then I figured it wasn't any use going higher

Today I finally got some time to further troubleshoot this issue, and by reducing the looptime to 4k/4k, the problem went away. I thought that the xracer v3.1 was able to run 8k without issues?

And did you make sure "motor PWM speed separate from Looptime" is disabled? (only available when not using DShot)
If that's not the issue then I would suggest re-flashing the firwmare with "erase" all settings, in case it's a issue caused by a problematic setting...

Yep, tried 32k, 16k, same as pid loop, dshot150,300,600. The only thing that fixed it was lowering the looptime. Haven't tried flashing new fw though...

I know it's 5 years old thread. Want to confirm again, you solve that issue by lowering PID loop time? Thanks!
