Tail servo horn setting

So I just put a new gear set in my futaba S9254 servo, centered my horn on it manualy, went to menu “G” and checked it again for center and its a hair off. If I move it a spline either way its off a little. How do I adjust it with the beast to make it perfect at 12 o’clock?When in doubt....fly higher!

You can't, you need to use a different servo arm. If you still can't find a servo horn to get it to 90 degrees, go with the offset that would simulate RIGHT rudder (this can even improve performance).

FWIW make sure that servo is running on no more than 5v.60% of the time, it works every time!

Which servo output arm are you using? Is it the 6 arm star? I have used it on everything from pattern planes back in the 80s to cyclic and tail applications today. It is plenty strong enough to use on the tail of even 700 sized helis or cyclics on 500-600 sized. If you look at the top surface of the arm, each individual arm has a small number molded into it. You can index these arms on the spline to get it into the correct orientation.

In over 50 years of using Futaba servos, I have never found a setup where I couldn't index the arm and find one that was perfect. Hope this helps.Logo 700, Specter 700, Goblin 700, Trex 700DFC, Gaui X7, Logo 690SX, Logo 600SX; Trex 470 Trex 500
