RE: 12 FG QUESTION
If you have "Elevator2" selected, the control and trim should be set to "NULL". They take their cues from the control and trim of "Elevator".
You can also go into the "Ailevator" section of the Model Menu
and adjust the movement on the second elevator channel. There are four parameters to be set there: up/down on surface #1, and up/down on surface #2.
You could also go into the ATV section of the Linkage Menu and adjust the "Travel" of Elevator2.
Another way would be to just change "Elevator2" to "Elevator". The Ailevator function won't work any more, but you'll be able to set up separate curves and points for both elevator servos. In that case, make the control and trim to be the same for both elevator channels.
