SERVO8_TRIM default is 1000?

I think it’s some sort of mistake, in latest Mission Planner.

SERVO8_TRIM was resetting to 1000, and it says default is 1000.

That’s not what I see as default for Heli

Edit: Nope, I take it back. I’m seeing the same as @dkemxr

When did you see these values, after Radio calibration or directly after you load a new firmware to a cleaned FC?

every time I connect the FC to Mission Planner, Servo8 Trim value goes back to 1000.

Every time you connect Mission Planner to the FC only the parameter stored in the FC is displayed but nothing is changed.

@Juergen-Fahlbusch is correct. Mission planner does not change parameters when it first connects to the FC

I’m not sure why the trim value is of concern. I haven’t looked but I don’t think the trim value is even used in the code. For the HeliRSC function, only min and max is used.
