Well.., data from a CC is not very reliable, at least the temperature not.

There is some problem with temp sensor on my Castle - as I see. I have to look for others logs. Today datas are more reliable. I don't knoe why
Current is logged by JLog with 1A step? On transmiter display there are still peeks of current >500A. Conections are without any loops.

Looking much better so far, I cannot see any hazard pointing on noise.

Only:

- RPM is going crazy during spool-up. Looks like it comes from the CC itself.

- RPM motor is a little high.. What pole number is setup by JLC?
(Please attach your CONFIG.txt.)

- The gear ratio isn't set yet in JLC (-> rpmUni - head speed).

- Capacity is looking very strange because of some negative(!) records for Imot. (Think I should force to unsigned integer.)
(Because of these short jumps in throttle negative current values appeared in between (pulse distance <500us).)

No, there is no step, nowhere, as well as not for Imot.
The CC will have a resolution (discrete pulse distance) of course.
Everything below 10 amps is rather inaccurate as it comes from the CC.

Motor RPM is high because it works without propeler (2600kV so 50-53k is OK) I don want to set gear ratio. For me motor RPM is more important. Motor of course is 2 poles
There are a lot of negative values of Imot I can see it now in Graupner HoTT Manager.

Best

Yep, I see now, 2-pole in config.
Set to your motor's pole number and also the gear ratio. The latter is no problem because we're logging TWO speeds, rpmMOTOR AND rpmROTOR.

OK
Oh, one thing - In HoTT Manager values are not negative...values are positive - 6533,5A

2-complement, integer to unsigned integer. Quite normal.

Yes, I know it Normal and not normal ;D But that is the reason of my peaks in current on receiver display.

Ahh, I see!

Okay, I will change that in the firmware to avoid negative values.

The negative current values are real, they're coming from the CC.
On the other hand I never saw negative values before and I am sure that also you will not see them in real flights.
The negative current values are due to that on/off that you have practiced and with no load.
