I am using two elevator servos, via my 12 FGA. The servos are Hitec 7955s. The neutral and end points are the same, and I believe the linkage is symetrical. However, while they start at the same neutral point, one appears to travel approximately one degree ahead of the other. They both stop at the same end point location. Can this one degree travel offset be corrected via the transmitter? I have reduced the difference using servo speed on the AFR screen, but they are still slightly offset.

If the servos have the same center point and the same endpoints, then the difference in how the servos are moving is entirely within the servos. Since no two servos match exactly, this can happen, and is rather common.

One way to work around the problem is to have both elevator channels set to "ELEVATOR" in the transmitter and adjust the AFR curves so that the travel matches as you move the stick. You won't have to change any rates or expo, but the AILEVATOR function won't work or actually be needed in this case, unless you have the elevators working with the ailerons, too.

Bax,

Thanks for the quick reply. The 12 FGA has channel one and two designated for elevator, using the 14 channel receiver supplied with the radio. I am a little confused regarding both being set to "Elevator", they are now coordinated using Ailevator. There is currently no mixing being utilized between the elevators and ailerons. By the way, the plane is a 50cc Extreme Flight Yak. If I designate them both as Elevator, individually, won't I loose the ability to use the Elevator trim button on the receiver. Is there a desciption of this process in the manual. Love the 12 FGA and would like to resolve the issue with the transmitter. Thanks again for your ongoing assistance.
