<DIV><FONT face=Arial size=2>I also ran them on my Hydeaway on the

countersink a piece of ply into the surface. By the way I stick a piece of

deal...Never had an issue yet..Hydeaway has around 500 flights and last I

<DIV><BR></DIV>
<DIV><FONT face=Arial size=2>When it comes to control horns for pattern
planes it seems to me that some of the most commonly used choices have a
major flaw.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>On my last plane I used the MK Aluminum
Horns on all surfaces except for the rudder where I used the IM pull-pull
horns. Both of these are nice horns except they have a major flaw when using
a pull-pull setup. The flaw is that the little black plastic arm that screws
onto the horn and connects to the clevis is so short that it doesn't extend
out over the hinge line. I know that with pull-pull systems it isn't
*absolutely* necessary for the connection to be exactly above the hinge, but
the further back it is the more slack there will be in the cable that is not
pulling. In my opinion with these horns the connection point is too
far away from the hinge unless the horn is virtually mounted on the
control surface bevel (especially when it comes to rudder). This can easily
be seen in these "instructions" for installing the MK horns <A
href="http://www.centralhobbies.com/buildingtips/mkhorns/mkhornsinst.html">http://www.centralhobbies.com/buildingtips/mkhorns/mkhornsinst.html</A>.
Notice that in this picture there surface isn't beveled yet and the horn is
almost on the edge.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>On my new plane I wanted to avoid this problem
so I did some searching to find a better solution. To begin with I looked
for a longer arm to connect to the MK horn, one that would extend out to the
hinge line. I found two options from Sullivan but both require too big of a
horn thread (6-32 and 8-32). My search then led me to two other choices that
seem to be good alternatives. The first is the ZNLine aluminum control
horns, but these are apparently only distributed by ZNLine (<A

which means an international order. The other solution I've found is by

but these control horns seem very pricey!</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>If anyone could point me to a longer 3mm
connecting arm that will fit on the MK and IM horns I'd be happy (BTW, I've
used the MK BB connectors on the MK horn and they still aren't really long
enough).</FONT></DIV>

<DIV><FONT face=Arial size=2>Is it just me, or have others experienced this
dilemma as well?</FONT></DIV>
