SITL with AC_CustomControl does not work

Made a custom attitude controller in AC_CustomControl. When I build and upload this to my board, all of the custom control parameters appear in my GCS, as expected.

When I try to build and run SITL, none of my custom control parameters appear in MAVProxy. The documentation for AC_CustomControl states that the SITL has custom controllers enabled by default, which seems to be completely false. Flagging “–enable-custom-controller” on the SITL build does nothing either.

I’ve tried this using both the sim_vehicle.py script, and doing “Simulation on Hardware”, and got the same result.

Is there any way to force SITL to have CustomControl enabled? I literally just want to make sure all the signs, inputs, and outputs are correct on my custom attitude controller before trying it on hardware.

Fixed:

CustomControl Parameters do not appear until you set CC_TYPE to the value of your custom backend, and (maybe) set RC6_OPTION to 109. You then need to reboot, and finally CC_AXIS_MASK and the rest of the CC parameters will appear.

It would be nice if the documentation included mention of this step…
