Are the params sets correctly? In particular with ESC telemetry my confusion is how to set FREQ and BW, somewhere I’ve read to use FREQ to target the lowest noise freq, is this correct?

I gave it a spin on the Matek H743-Mini, all good. Nice!

However on the Kakute F7 Mini there is something going on with RPM Telemetry. 2 outputs good, 2 not.
