Hi all
I'm wondering what the latest is on throttle control through the apm for nitro/gasser powered helis?
My current thoughts on controlling the throttle are to have my channel 7 (I've mixed CP to Aux2 - which is channel 7) go into the throttle in of a align 3gx unit fitted with a governor and then from there to the throttle servo - I know this will work but this seems stupid.
At the moment I can't seem to find a way to get any throttle output - even passthrough of the channel via my pixhawk apm
I have a trex 600n dfc that currently runs a redline 56 nitro engine but we're modifying a petrol engine to fit within the airframe. The CCPM mixing seems to be great through the apm and I now have vibrations down within the guidance - all I need now to try flying with the pixhawk is some way of controlling the throttle.
Thanks in advance.

If you are using an external governor, can you not use the signal normally output from Ch8, intended for an ESC in governor mode, to drive the governor? I would think that would work?
I do have code running now that allows control of a nitro/gas throttle servo in a simple open-loop V-curve, similar to what you would have in your radio. Hopefully it will come out with AC3.2.
