Aloha fellow RCU flyers,

I am having some problems installing/operating standard ball bearing Futaba servos in the fuselage of my Great Planes .61 Escapade. When I give close to max aileron and rudder input in either direction the servos make the dreaded buzzing sound and the control surfaces have an unequal distance of travel (to far in one direction and not enough in the other). When I unscrew the servo from the servo tray it wants to move forward and up out of the tray.

To try correcting the problem I repositioned the servos by sliding them left and right in tray, switching to Dubro EZ connectors so that I can adjust the length of the push rods, and repositioning the servo arms themselves. I have built two ARFS before this one and have never had this stubborn of a problem with servos. What can I try next? Any help is much appreciated.

Thanks!
