<<I don't believe the same kind of failure is possible with the 8A as the
trim shaft passes through the rear plate instead of resting in it like the
6A.  Don't know if this is a matter for the rest of you to consider but I
can attest that the stick shake that resulted from the failure was quite a
"heart starter" for me.  I can take pics of the housing and parts if anyone
needs to see the servo.>>

A while back I received a "design" bulletin from Lancair recommending the
installation of a friction device in the trim system.  This would presumably
add enough friction to prevent trim tab flutter if the trim mechanism broke.
I haven't taken it too seriously yet as I feel that their recommended
implementation left something to be desired and I haven't yet figured out a
better way.  Sounds like it would have prevented the problem above (not the
failure, but the flutter afterward).  Has anybody installed one of these
devices?  Any opinions on whether they are justified?
