Sounds interesting, let me know what you can find.
I need to do the same thing, but as I’m installing a PTO driven generator, I will need a 50Hz (3000rpm) input to get my power supply up to spec, so rpm is somewhat critical.
I got a throttle rpm set out of an old range rover, out of which this whole generator set came, but that has a real bulky actuator.
Maybe something more modern and plug-and-play can be found. Have to do some searching on it.
