Default 7C and Dual Elevators

I'm using a 7C on a GP Extra with dual elevators and managed to program dual elevators, but the trim switch only trims the master servo? To match the other other servo I land and make subtrim adjustments. Has anyone figured out a way to link them to both change with the regular trim switch? Didn't find any answers in the manual, so this this may not be possible on this transmitter. Worth a try to ask.

Cheapest cure is to use a Y harness with servo reverser incorporated in one lead or one side of a standard Vtail mixer.
Digimix which also provides extra travel adjustment.)
V-Tail mixer.
Alternatively, use servos which, in standard configuration, operate in reverse directions e.g. Futaba X 1 and Hitec X 1 or 2 X Hitec digital servos which are fully programmable and have the direction of one of the servos reversed at time of purchase or use a HFP-10 Hitec Digital Servo Programmer (& tester for all servos and receivers yourself.
