how does a matchbox work?
I have an airplane with dual servos for the elevator. JR 8103 TX. Linkages are all idential. I've set up the radio with the correct end points, subtrim, trav adj. etc.
The elevator halves still do not perfectly match. They are fine transitioning from up and down, however they tend to go a little astray when nearing the travel limit on high rates. I heard a matchbox will fix this problem, however, I see no good articles on the basics of how it works. Please advise.
