JR output arm stabilizers

[Grow Pattern]

The ball component actually causes some drag, depending upon how tight the pull-pull wires are set. The servo will buzz less when the output shaft is supported above the servo arm. I have even seen the brace stop the rudder dancing until the servo could be serviced with a new pot.

I replace the ball-joint above the servo shaft with a ball-race clevis (MK style) to reduce the friction and the rudder then centers almost perfectly. I support the new bb clevis by cutting off the ball on the servo screw and tapping it for a 3-mm bolt. Or I replace the bearing with a 3-mm id ball-race and use a 3-mm bolt and spacer to do the same thing.

Regards,

Eric.

  Do we really need this output arm when using JR 8411 in the rudder (pull-pull system)? As far as I know, the main output gear is supported by two ball bearings.

    I don't think JR makes them anymore but here is one that is the same thing by K+S for Helis:

      Does anyone know if these are still available?  These were a rectangular metal bracket that went around the servo, over the mounting flanges.  This bracket held a post with a ball end, which connected to a ball ended bolt for the servo arm, via an arm with swivel joints at each end. 

      Thanks
