In the latest version of firmware (arducopter trad heli), with the latest QGC there is no longer an option to set channel 8 to throttle output so I can tie it to a knob. I rolled back to QGC 3.5.6 and it returned, but I had to re-flash the older firmware (arducopter-heli-stable-3.6.12) manually (which I dont like doing, I like QGC to find the fmuv2 version on its own as its safer than manual updates).
Is there any reason for this change and I missed the note somewhere? I cannot use arducopter without this ability and I tried to map it through the full param list but it didnt work. I left it on the older QGC and older firmware but ideally I would like to use the latest version.
Below is the version I am forced to use with the latest QGC and the missing option in ver4:
