Carbon Push Rod Size

[Rick Wallace]

Agree about the pushrod oscillation prevent-er -    I think someone also
pointed out awhile back that putting it somewhere *other* than the pushrod
center would be a very good place in order to damp the 2x, 4x, etc harmonics
that can occur in the pushrod.

I'll second the recommendation for a pushrod guide.    I cut an oval hole in
bottom about

5 x 2 inches to work through to install the balsa and foam guide.

Hi Moose Boy,

The 1/8" CF rods are really nice for the ailerons.  Very stiff and light,
but make sure you use light clevis/control arms too or it will not buy you
much.  Not sure what the elevator setup is on the Focus.  If it's down the
middle, the 5/32 and 3/16 rods are both very light and work fine.  a guide
inthe center of the rod is not a bad idea.  This doesn't have to be
structural.  Just something to prevent oscillations, like a cross brace of
light balsa with a small cube of foam glued on top of it.  the foam would
have a slice halfway through which the rod slides in.

What size Central Hobbies carbon pushrods should I use on my Focus.  The
homemade ones from the previous owner don't give me a warm fuzzy.  These
push rod will be for the ailerons, and elevator halves.
