OK so I discovered that ESC telemetry was turned on, and was stopping the AUX port from outputting to the throttle servo.
What are the default values for the min and max pulse width? They dont seem to affect the end point of the throttle hardly at all.

Still, at least now I can control the throttle.

usually servos are from around 1000μs to around 2000μs
defaults of spirit is 1100μs to 1900μs

try to lower them a lot (ex 1400 - 1600) you will see they will limit the servo angle

Thanks for the help urgno. I think I have everything set up now and may even try to fire her up tomorrow.
I have checked the gov sensor works, set the max headspeed to 2200 and the main ratio to 8.5. I've got throttle limits set and throttle cut works.

What could possibly go wrong :-)

One last question - I have Outrage Servos so I am expecting the current draw to be quite high. The AUX on the spirit is traditionally used for a second power run from the Rx but as its on the throttle this isnt now possible.

Can I use a Y-Split for the extra power side from the Rx and then run the throttle servo signal pin to AUX pin 3? (If you see what I mean).

Cheers,
Jim

ofc you can use Y
that’s why they are available in the shop ;)

just try to connect the power source nearest possible to the power drain ( servos )

you can disconnect one of the outrage then connect it with the Y
together with the power source

I'm probably going to make a power board in the long run.
