RE: Elevator mixing setup question.
Larry I wish I knew more about your radio. I can tell you how I mixed it on my 9C. You do have to run a wire for each servo. Then 1 Aile goes in the Aile plug The other in the flap plug. The radio has to be set to flaperon setting. The I used two of the programable mixes. I mixed one with the master as the ELEV and the AILE as the slave. Then I mixed the other with the master as the ELEV and the flap as the slave. On this radio you change the mix from + to - depending on if you want flaperon or spoileron.
Is there a support section on this site for Hitec? If there is I would ask again there.
