On another Plane I have with Split Elevators/Dual Servos, I put each Servo on a separate Channel so I could adjust each Servo separately; on my newest project, it also has Split Elevators/Dual Servos. However, because of Radio limitations, I am trying to free up a Channel for another function. In order to be able to adjust each servo separately yet only use one channel for Elevator, will a JR Matchbox work in this situation?

I bought one and tried it out on the bench with 2 Servos attached, and when I tried to adjust the endpoint on one of the Servos, I noticed that the servo movement of adjustments in either direction of rotation, was made in such minute or small increments with a very small overall range; I know that through Push Rod and Servo Arm geometry that this may be sufficient to make a difference in Control Surface alignment, unified movement and have the same identical End Point. Are these small Increments of movement Normal for these JR Matchboxes, or is there a better method to be able to adjust each Servo separtely without having to use 2 Channels; I have a servo programmer but I wouldn't think that would work because the Servos have to be mounted in the Plane to observe and measure actual control surface movement and end points. Also, joining the push rods into one pushrod for single servo is not possible.

For reference, not sure if it makes a difference, the servos are Hitec and are Standard, the manual states that the Matchbox will work on Standard or Digital; or will these just work better with Digital Servos?

Thanks.
