Has anyone had any problems with Multiplex servos not centering themselves?I was helping a friend today with a new jet(JMP Firebird).It has a Multiplex on the elevator which is a full flying stab BTW.We were CONSTANTLY having to trim the elevator because it seemed like the plane was trying to "hunt".Any advice or input would be greatly appreciated !!
Thanks in advance,
Jason

I would look for play or lack of balance. Also the servo should
use 90% of it's travel.

I had Multiplex Royal BB's controlling the cyclic on my Hirobo Sceadu, and they seemed to get a bit "sloppy" after a while. I replaced them with Futabas and the problem went away. Now i have the Royal BB's as aileron-servos in my Magic 3D, and they never seem to center there either...

I have used many MPX Royal and Profi mc/V2 digitals with never a centering issue. They have performed flawlessly.
