<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>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>
