Hi,
when you are changing "receivers" or simply Throttle port then Signal might be very different actually.
Spirit unit is sending Throttle signal immediately after powerup.
1. In the Diagnostic tab Throttle signal should start with 0% so that 0% in radio correspond with 0% in the Diagnostic tab.
Similarly 100%. But this depends on your throttle curve - your curve might be for example 80% flat line. So you should see 80% ideally.
2. When passing through Spirit the unit is mapping the signal according what you will set in the General - Throttle - Throttle Range - Min./Max.
To make it work in the same way as with receiver please set Min. to 1000us and Max. to 2000us in the unit.
Then it is likely it will not matter where you will connect the receiver.
JETI receiver has range 1000 - 2000us by default, which is different from Spektrum. With Spirit unit you can change the range however you wish.
If ESC will not arm, then the Min. value is likely too high. Or in other words your ESC is calibrated for a lower Minimum point which was caused likely by calibrating with JETI receiver previously.

Ha! Thanks, Tomas - I was working through the problem again 'from first principles' and solved it - then a few minutes later I read your perfect reply
All this after many days of head-scratching and frustration.This is inexperience on my part, not realising the Jeti system has a different throttle range than Spektrum (which I used before). In the end, I set the end-points like this:
1. Jeti DS-12 min/max throttle (servo setup) max negative: -100%, max positive +100% (default)
2. Throttle curve set to 0 - 50 - 100 straight line
3. Castle Creations ESC set to 'factory defaults' except 'helicopter' and 'fixed endpoint' mode
4. Spirit RS throttle range set to 1100 - 1900 (default)
5. Connect battery, throttle at 100%, open Spirit settings / 'General-Governor' settings, then increase 'Throttle Range: Max until ESC recognises top end-point. Drop throttle to 0%, then reduce 'Throttle Range: Min until ESC recognises bottom end-point. Now (surprise-surprise!) the range is 1000 - 2000 and all working.
Again, thanks Tomas for your help and instruction. Of course after the solution it all seems 'logical and obvious' but the confusion was very real before.....
Cheers, Andy
