I want set both Elevators adjustment on the tirm tab on the radio? Currently I fly with DX7 and have the left elevator on ELEV channel and the right elevator on AUX2 on the receiver.

They are mixed on number 1 mixing Elev - Aux2 ON
Rate +100%
+ 100%

SW : ON
Offset : +1

When I am in flight if I adjust trim then only the left elevator moves, is there a way to have both moving on the trim tab so you can adjust equal amount in flight ?

I don't like using the Y leads with the reverse set up as I have seen them go out of adjustment due to heat on a sunny day.
