<DIV><FONT face=Arial size=2>Welcome to D6. You already were a D36'er but
now your assimilation is complete.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>I could have saved you the agony. Tried to do
the same thing about 6 months ago with the same outcome. I wanted them to
screw to my own 6-32 threaded rods so I could set the rod 3/4" behind the hinge
line. Paid the big bucks for the set and used the long arms anyways.
HOWEVER, it didn't work out. The long 3/4" reach of these "overhang"
pieces looked fine with my rudder at neutral, but when the surface deflected
they formed a weird angle with the pull-pull cable and almost hit the
fuse. I didn't like the look. I no longer think these are the cats
meow. The fix was to use the small white nylon old-style pieces but offset the
control arm at the servo end. Looks better and no weird stress angles on
the cables.</FONT></DIV>

<DIV><SPAN class=020000316-29112004><FONT face=Arial color=#0000ff size=2>I
contacted Dubro wanting to purchase only the plastic overhang piece as I
probably won't ever use the bolts and didn't wish to pay for the entire unit.
They beat around the bush for almost 3 months before finally refusing to sell
them to me. The first answer I was given was it would have to be a
minumum of 50. I said no problem ,what would the cost for 50 be. Then they
responded stating they didn't sell the parts individually.</FONT></SPAN></DIV>

<DIV><SPAN class=020000316-29112004><FONT face=Arial color=#0000ff size=2>I
sure would like to locate such a part by someone. Most all others seem quite
short.</FONT></SPAN></DIV>

<DIV><SPAN class=494275614-29112004><FONT face=Arial color=#0000ff
size=2>Hello Bob,</FONT></SPAN></DIV>
<DIV><SPAN class=494275614-29112004><FONT face=Arial color=#0000ff size=2>Go
buy some DuBro # 867 control horns. They have almost 3/4" of overhang
between the bolt and the little hole for the clevis, in the little screw-on
pieces.</FONT></SPAN></DIV>
<DIV><SPAN class=494275614-29112004><FONT face=Arial color=#0000ff
size=2>Use those pieces, but set the bolt and nut aside, and see if the
little holes line up with the center of the hinges.</FONT></SPAN></DIV>
<DIV><SPAN class=494275614-29112004><FONT face=Arial color=#0000ff size=2>If
not, then drill new holes in the black plastic bits so that they do
line up: one straight line through both holes and the center of the
hinge.</FONT></SPAN></DIV>
<DIV><SPAN class=494275614-29112004><FONT face=Arial color=#0000ff
size=2>Now when you get the horns all the same length, it will be much
easier to get the throws matched in both directions.</FONT></SPAN></DIV>
<DIV><SPAN class=494275614-29112004><FONT face=Arial color=#0000ff
size=2>This is absolutely necessary for matching two elevator halves
properly, but is also a good idea for rudders.</FONT></SPAN></DIV>
<DIV><SPAN class=494275614-29112004><FONT face=Arial color=#0000ff
size=2>The problem with the stock setup is that the cables slacken at
the ends, and tighten at neutral.</FONT></SPAN></DIV>
<DIV><SPAN class=494275614-29112004><FONT face=Arial color=#0000ff
size=2>While this might sound like a good thing, it is awful: the servo has
to fight the tightening cables as the surface comes closer to
neutral,</FONT></SPAN></DIV>
<DIV><SPAN class=494275614-29112004><FONT face=Arial color=#0000ff
size=2>then as it gets there, the surface may try to "spring" to the
opposite direction.</FONT></SPAN></DIV>
<DIV><SPAN class=494275614-29112004><FONT face=Arial color=#0000ff
size=2>The servo and gear train will prematurely beat themselves up chasing
this problem.</FONT></SPAN></DIV>
<DIV><SPAN class=494275614-29112004><FONT face=Arial color=#0000ff
size=2>You want the cable tension to be almost constant throughout the
throw.</FONT></SPAN></DIV>
<DIV><SPAN class=494275614-29112004><FONT face=Arial color=#0000ff
size=2>There will be pictures of this when I get the Excelleron review out
the door.</FONT></SPAN></DIV>
<DIV><SPAN class=494275614-29112004><FONT face=Arial color=#0000ff
size=2>One of the previous posts pointed to a website that showed the proper
geometry.</FONT></SPAN></DIV>
<DIV><SPAN class=494275614-29112004><FONT face=Arial color=#0000ff
size=2>DuBro and Rocket City both make parts that are useful, for this
problem.</FONT></SPAN></DIV>

<DIV><SPAN class=494275614-29112004><FONT face=Arial color=#0000ff
size=2>Check DuBro.com and put #867 into their search engine, you can see
the lonng overhang part. It's either 5/8" or 3/4" from bolt to clevis
hole.</FONT></SPAN></DIV>
