Reversing a servo internally for dual elevator application
This question is based on using one TX/RX channel for dual servos on elevator.
I have read that often a reversing Y harness will not give equal throws in this application and that internally reversing the servo is a good option.
The general instructions seem to be (for a brand(s) other than yours) is two steps, 1) reverse the wires on the motor; 2) reverse the two outside wires on the potentiometer.
.Questions: 1) Which of your servo series lend themselves to this type of reversing? (edit: found another page your servo site, appears all your servo Have SMT ,motor to circuit board hard wired.)
1A)Does Futaba offer reversed servos or a free service to reverse them?
2) The SR10 has a centering adjustment, but will it provide equal throws (travel distance) both directions?
If there is another good solution please elaborate.

Reversing a servo internally for dual elevator application
Hi mikenlapaz,
Years ago Futaba did manufacture "reversed" servos for the public, but with the advent of servo reversing in the systems, there was not the call for these as there had been.
1.) We cannot offer you any assistance at all in modifying our servos in the manner that they were meant to be used, nor will we do the mofication ourselves.
2.) Our suggestion would be to look into the "servo reverser" that you are looking at, as it will offer the equal throws and adjustments that you want.
I hope you find this information helpful. You can also reach our Futaba support technical team at 217-398-8970, or via fax at 217-398-7721.
Sincerely,

9C and 2 elev. servos
I am using this mix on 2 of my planes with a servo on each elev. half.I noticed that the elev. on ch. 8 seems to have a slight delay when I deflect fast.I thought it might be the servo so I switched them and it still does it.Any thoughts.
