Error in AETRFG.main.mix?

Hopefully this is the correct place to put/ask this…
The last line of this mixer, line 76, defines the mixer for the gear. It states 3 for the control group (the rest of the mixes state 0).
Is this the reason I can’t get the gear channel to respond? Should that be 0?
@lorenzmeier I believe this is the mixer that “standard plane” loads?

ok, i see what the mixer is doing…it is echoing the AUX1 RC passthru channel. Wish it wasnt like that, as this reduces the number of channels and now i need 1 more.
