<DIV><FONT face=Arial size=2>David, we sold the rod/horn/coupler/clevis set-up
you are talking about. Discontinued the 4-40 ones after a few(even hardened
steel) ones on the elevator and rudder bent/broke on Pattern planes.Ailerons
showed some movement also.. We now have/suggest using 6-32 or even the 6-40
ones that Rocket City used to sell. Much stronger and only a few grams heavier.
NO sense shaving something that can destroy you!.</FONT></DIV>
<DIV><FONT face=Arial size=2>Just our experience, and I am sure there are a lot
flying with 4-40s</FONT></DIV>

<DIV><SPAN class=929582806-05022006><FONT face=Arial color=#0000ff size=2>I
like the 1" MKD Control horns, and if you want ball bearings, the MK clevis,
both available from Central Hobbies. These work really good, and
the length is somewhat adjustable. I really like the anodized aluminum
horns that RCME once sold, but you said that you did not want to spend a lot
of money.</FONT></SPAN></DIV>

<DIV><SPAN class=929582806-05022006><FONT face=Arial color=#0000ff size=2>If
you don't want to spend less than the MKD horns, then long 4-40 bolts with a
non-threaded shank will work nicely. All-thread will fail. It is
important that the part of the bolt that is glued into a hard point dowel is
not threaded, and that the threaded portion is minimum length. Scratch
the shank with alum oxide sand paper before epoxying into hard point. I
have never had one of these fail or pull loose from the hard point. <A

source for long bolts.</FONT></SPAN></DIV>

<DIV><SPAN class=929582806-05022006><FONT face=Arial color=#0000ff

glue these into the the control surface. G-10 is available from <A

Control horns<BR><BR></FONT></DIV>
<DIV> What alternatives are there to the Chip Hyde control horns. The
plane I'm building (Genesis) is setup with ply plates that are designed
to use these They are a little pricey. Mind you they look well made. Are
there horns on the market that are similar?</DIV>
<DIV> Or how about someone out there that has a set of these that they
want to sell me. TIA,Mike</DIV>
