MK ball bearing connectors

[Paul Reed]

Jim,
I assume you are talking about the control horn clevis. I use MK control
horns as well as the control horn clevis and ball bearing rod adjuster. If
you are using the MK control horns and you need to make a half turn
adjustment you can remove the control horn, attach the clevis and reattach
the control horn to the control surface. It's a bit clunky but it works.

By the way if you are also using the ball bearing rod adjuster make sure you
have the open side facing up. There is a lip on the nylon piece that the
bearing seats against. This lip has to be facing the servo horn. If it is
not facing the servo horn the nylon piece can separate from the bearing
leaving the bearing and screw attached to the servo horn.

Regards,
Paul Reed

  Hi All,

  I'm using some MK ball bearing connectors on my plane now and have a few
questions for those that use them.  When installed on the elevator, I only
have the resolution of 1 full turn because the direction the small Philips
head screw must pass through.  Are there any tricks to working around this?
The aileron install seems fine as you can access the screw head from any
direction.



  For those that use these devises, are there any improvements, maintenance,
or things to be aware of?  Has the screw ever backed out?

  Thanks,

  Jim W.
