<DIV><FONT face=Arial size=2>Well it looks like the standard 6-32 threaded bolt
from the ACE Hardware bin is they way to go. That is what I have been
using all along I just haven't heard the pro's and con's on the
subject. I use the flat head bolt and counter sink the hard
point. Using the 1/4" 6-32 threaded aluminum sleeve as a stand off
seems to give them a lot of strength and locks the bolt to the control
surface.</FONT></DIV>
<DIV><FONT face=Arial size=2>Although I have seen them used with out this stand
off too. </FONT></DIV>

<DIV>Ive been using all thread rods from hardware store.</DIV>
<DIV>It's my understanding those are less likely to break than bolts.</DIV>
<DIV>No problems with older 1.20 YS bird or current OS 1.40.</DIV>

<DIV>Which brings up a good point here.</DIV>
<DIV> </DIV>
<DIV>Do you use steel bolts or stainless steel bolts.</DIV>
<DIV>Stainless is a softer material and would it be prone to breaking
easier?</DIV>
<DIV>Or is the harder steel bolt more likely to snap under vibrating
conditions?</DIV>

<DIV>I've been using 6-32 bolts to make the control horn arms for my 2M
setups so far. It seems like that might be overkill and that 4-40
would suffice. Is it OK to go lighter like this?</DIV>
<DIV> </DIV>
<DIV>Thanks</DIV>

<DIV>Ed I wouldn't do that especially on ailerons. I have had 4-40's snap
off like twigs on 90 sized models before. The vibration kills them.</DIV>
