<DIV><FONT face=Arial size=2>Thanks to all for the replies! Matt/Ed - I'm
using the long screws. They actually have a separate p/n from
Horizon...and they work really well.</FONT></DIV>
<DIV><FONT face=Arial size=2> The slop - I discovered - IS
vertical play in the output gear. Actually appears to be in the base of
the main gear where the pot actuator rests. Doesn't look like it's missing
any spacers; the bearing has the top o-ring. These are JR 8231's...I seem
to remember kind of a fiber-washer/spacer thing below the o ring but on top of
the ball bearing race... </FONT></DIV>
<DIV><FONT face=Arial size=2> Does that sound
familiar?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>This isn't a big deal, as the arms are tight, and
the screws plenty long enough. Just hadn't run into noticing this kind of
play in the system before.</FONT></DIV>

FAMILY="SANSSERIF"><BR>Bob are you talking about the heavy duty plastic arms?
If that's what you are talking about, I had a similar experience as yours,
with one arm not seating firmly all the way. The retaining screw was the
standard short that came with earlier generation JR servos. <BR><BR>Didn't
think that much about it since it was an aileron application. The good news is
it was an aileron application, with its built-in servo redudancy which saved
the plane possibly. Bad news is the output servo splined shaft tore off the
servo.<BR><BR>Two things: first, the short screw was a little too short and
did not reach down far enough into the splined shaft. Second, The arms are
thicker in the screw mount area and that exacerbated the problem. <BR><BR>If
you use these, make sure that the retaining screws go far enough into the
shaft. Better yet, toss the arm and refit another that fits AND use a longer
retaining screw. The heavy duty arms are very robust and I will continue to
use them (with extra care thgough)<BR><BR>Matt K</FONT>
