RE: 10x origin mixing... at a total loss here
Hmm interesting...
Well I figured it out. I just plugged the retract into AUX-4 and it worked fine.
OK so that's interesting, what's more interesting is I plugged the tailwheel servo into AUX-3 and mixed that to rudder and THAT worked just fine to!
Apparently my RX doesn't like having the retract servo on AUX-3!
