Equal Elevator trav w/ dual servos
 

Im using an MSA-10 to run 2 servos for elevator control. I am having problems equalizing the travel of both servos throughout the travel range. No mater what I do, the right side travels higher on up, and the left side travels lower on down. Could I be doing something wrong? I have also noticed that the two elevator servos do not move PRECISELY in unison. They might be off by a click or two during movement. What should I be checking or trying? I am using a Futaba 7CAP, and yes ive refrenced the instructions for the MSA-10. Please help. Is the unit faulty?

You have posted in the beginners forum. You might get more response if you ask in the giant scale forum, where this issue comes up more regularly. Good luck.

I am not sure what the MSA 10 is, however I do know that the only real way to make your situation work is to do it with your radio. You need to have one of your elevator halfs be the master and the other be the slave in programming on your transmitter. The slave would be plugged into channel 6 or 7 on your receiver and then programmed to follow your normal elevator channel. Good Luck, Dave

The manual for the MA-10 explains how to set the neutral and end points for each individual servo and end points for paired sets from the matchbox.
No TX magic necessary. When the endpoints and neutral are trimmed to match the travel should be identical.
Right now they are off because one is traveling further then the other.

Wish we could upgrade our 7C's with the 7C 2.4g software.. It can do it on the TX.

The issue seemed to me a mechanical setup issue. Thanks for all the help! :)
