I am trying to get AH working with my Spektrum DX8, but it seems that there is only one two-position switch on this radio (Gear). That two position switch I already have used for switching between AL and Manual flight modes. Has anyone tried using the three position switches Aux 1, or Aux 2 for AH? Since the mid point of these switches seems to be zero I am worried that it might cause problems. Any other workarounds?
