Hey all,
Had a dog of a time finding this setup, I used it, and now it works!
Here is what you do.
For two motors using differential thrust to control Yaw, grab your Spektrum Dx6e transmitter
on the Spektrum Receiver AR6110:
Left Motor ESC plug: Throttle
Right Motor ESC plug: Gear Caution: remove red wire on one servo plug first if both ESC's have BECs!
Go to mixing menu:
Mx1: THR > GER Rate 0% 100%
Mx2: RUD>THR Rate 0% -70%
Mx3: RUD>GER Rate 70% 0%
Make sure you setup a switch for each mix in case you want to turn it off.
Happy Flying
