plug the RX's throttle channel into the mixer's elevator input and the RX's rudder into the rudder input.
When the throttle is at minimum, both outputs from the mixer go to minimum, when the throttle goes to maximum, both outputs go to maximum. When the rudder is slipped left and right the outputs are adjusted up/down in opposition to each other -- there's your differential.
If you plug everything in and your motor differential runs opposite of the rudder, swap the two outputs.
*BE ADVISED* your motors *CAN* kick on with throttle at minimum but rudder off-center. it's probably best to burn the DX6i's two mixes to cancel out the throttle and rudder, assigned to the same switch as a safety.
That's great Dan, thank you for the explanation I'll let you know how it goes if I use this method.
