Default LS-4 Trim Lock coming loose with stick deflection?

JJ and P3 - thanks for your help!!! It is esp. helpful to know that
it is a *known* issue that doesn't warrant replacement of parts.

Hi Folks -


Quick question - does anyone have experience with the LS-4 Trim Lock
coming loose with large control deflection?


I'm not quite sure what's causing the mechanism to slip - whether it
is a cable adjustment issue, weak spring issue, or whether the
brackets that lock the tube are just worn out of round.


Thanks for your help!

I believe they are all that way, John. Trim is a fine adjustment not
meant to hold with full throw movements. After wild movements, re-set
the trim at the desired speed. You might look at the friction plate to
see if it needs to be repositioned a bit in order to give more holding
power.
