<DIV><FONT face=Arial size=2>I don't have one loose in my hand right now...to
remember how they are attached to the base...Its sturdy though no question about
it....I think its molded plastic around the metal horn. The base is
plastic.....I was able to get them over the hinge line....They make a med and
small that central carries and there is also a large version too. Gator might
have the Large ones....Heck Central might have the larger ones
too.....</FONT></DIV>

<DIV><FONT face=Arial size=2>Troy,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Actually I'd looked at these on the central
hobbies web site but there were some things that concerned me about them.
</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>1. From the picture I couldn't tell what the base
was made of or how the horn was connected to the base and I wasn't sure how
sturdy it was.</FONT></DIV>
<DIV><FONT face=Arial size=2>2. It didn't look like there was much of an angle
and I wasn't sure that it would be enough to allow that tiny arm to reach the
hinge line.</FONT></DIV>
<DIV><FONT face=Arial size=2>3. Initially I was concerned about it being
mounted on the surface with ply and not having a rod go through to the other
side, though I've since learned that this is also how the ZNLine horns are
mounted.</FONT></DIV>
<DIV><FONT face=Arial size=2>4. And finally, I felt that a single rod through
the surface would be easier to align evenly on each side, assuming that I can
drill a straight hole :-) </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Given that you've had good luck with them it
sounds like they should work fine. How would your respond to my concerns #1
and #2?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>BTW, I hope you can make it to the Hot Springs
contest. After reading all of your informative posts it would be great to meet
you.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>

<DIV><FONT face=Arial size=2>They work well I have them on my

<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I also ran them on my Hydeaway on the
Rudder...Super Easy to install...I use a Dermal Router attachment and
countersink a piece of ply into the surface. By the way I stick a piece of
balsa in the surface also then router it out....Sand flush and its a done
deal...Never had an issue yet..Hydeaway has around 500 flights and last I
heard its keeping the new owner very happy.</FONT></DIV>

<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

href="http://home.att.net/~rc-enterprises/rcme_014.htm">http://home.att.net/~rc-enterprises/rcme_014.htm</A>)
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>
