<DIV><FONT face=Arial size=2>I took a (2) pieces of foam about 2"sq x 4" long
and pushed them onto the c.f rod and placed them about 6 inches from each
end. I could then move the pieces back and forth to tune out the
harmonic resonants. Just watch the rod at various engine speeds to see
what it does. When it vibrates it is amazing that any of them would hold
together. </FONT></DIV>

<P>Agree w/ John about using foam as a vibration damper. Also, someone much
wiser than me pointed out that whatever is installed should NOT be halfway,
1/4 way, or any reasonable fraction of the pushrod length because these
may end up as stationary nodes in the vibrating rod, and end up doing no
good. </P>

<DIV></DIV>>Be very careful about alignment. An extra bushing on the
shaft can cause a lock up under vibration.
<DIV></DIV>>A foam rubber damper is safer. It can be as simple as a wad
of foam or as complicated as another bulkhead.

Pushrod?
<DIV></DIV>>
<DIV></DIV>>
<DIV></DIV>> I've mounted the bellcrank and will use
Central's carbon fiber push rod. The pushrod length from servo to
crank is about 28".
<DIV></DIV>>
<DIV></DIV>>
<DIV></DIV>>
<DIV></DIV>> Is it necessary to install a support of the
rod halfway down the fuselage to prevent flexing. And
if so does anyone have a simple way of doing this inside a fiberglass
fuselage?
<DIV></DIV>>
<DIV></DIV>>
<DIV></DIV>>
<DIV></DIV>> TIA
