Well maybe not KST in general, maybe just one of mine. I have a mix of version 1 and version 2 KST's
I wish there was an in line filter we could possibly use to guarantee that governor signal was clean, everything else is perfect.

Bench testing with the H3050s shows no rpm sensor noisy logs. I'm still waiting for parts to repair mine to truelly test it

If a servos is causing noise, might try to put ferrit on servo lead to filter noise source and find cause this way.
I do allways pug a low esr cap on free FBL Servo port or with Y cable on any servo to fillter noise on bec power close to servos.
Rpm Filter of 2 means allmost no filter, higher number means more filter.

I use 10V 2200uF low ERS Typ Capacitor like UPW1A222MHD:

If you can solder yourself, just take old Servocable and solder black to - and red to +.
Plug it to free port or use Y Cable on any TS Servo and plug Capacitor to it as well.

I guess any RC Store have such protectors, like HK sells them as well.

So i flew my oxy with the h3050s and still have dirty rpm signal. I'm going to try the capacitor next. If that doesn't work, I'm giving up

The problem is in the hobbywing v4, it's confirmed.
