Spirit System

I have an SAB RAW 500 with an YGE Saphir 125 v1 ESC, a Spirit GT FBL, a Frsky R-XSR receiver and a Radiomaster TX16S II Max transmitter.

I'd like to use the Spirit FBL as the governor. Using the YGE PC- & Update Tool to select '(Heli)Ext.-Gov.' a window pops up called 'RC system', asking me to choose between: Graupner / Jeti / Multiplex / Futaba / Mikado VBC / PowerBoxCore / Others (see picture attached).

When asking YGE which one of the 'RC system' options to choose, they replied: "The selected radio is important for the correct throttle endpoints.
In this case I'm not sure which endpoints the ESC gets. If from the Spirit or from the Radiomaster.
So I recommend to select the mode with the mode setup with the throttle stick, as written in the manual.
This way, the ESC will read in the correct throttle endpoints from your radio automatically. Please select Mode 1 for external Governor here.
"

Is someone able to tell me which endpoints the ESC gets and therefore what option I should choose in the 'RC system' window?

Nevermind, instead of doing it via the YGE-connect tool, I'll do it old-school with the stick-'n'-beep method as recommended by YGE

Spirit default endpoints are exactly same as YGE's. So there is no need to calibrate your ESC if it is new.
It is only needed to set your radio to match 0 - 100% in the Diagnostic tab of the Spirit Settings software.

Thank you Tomas. I bought it second hand (was connected to Vbar with previous owner), so I'll recalibrate to make sure.
