<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>> 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
