I had to put a carbon rod into service as a stab axle once. All I had was one
of insufficient diameter. Luckily, I had a piece of brass tubing that it fit
into perfectly, and the brass tube fit perfectly into the carriers in the
stabs. I thought this was a perfect marriage of the stiffness of th
Hi Guys,
For some reason you are commenting on whether Carbon Rods are 'good' or
'bad' for using as stab axles, but my thread had nothing to do with that
topic,
it was about YOU finding out for yourself what kind of force it takes to break
a 1/8" carbon rod the length of a stab axle, about
Sure you can't break the rod with you bare hand, because you hands
have soft corners. Put the carbon rod into two brass tube and try
again.
I have seen 1/4" stab rod snap in a 100" glider on landing. The
carbon rod rotates in the brass tubing will forma stress point. For

I have seen even a 1/4" CF joiner fail on the Stab of a Onyx JW. As stated
before, the CF has to be protected. The one I seen fail, had marks in it
which lead to it's failure. Changes were made to fix that problem. Just
have to keep a close eye on CF stuff. Great stuff if it is taken care of.

Its not so much how hard it is to break the rod when its in good
condition. It's plenty strong. Its knowing when the strength has
been compromised with cracking after a few dork landings or an
unfortunate vertical arrival. They become very easy to break once
they have a crack starting to de
I've seen this topic for years and so decided to see what it would take to
break a 1/8" carbon rod with my hands which have considerably higher bending
capability than a stab on one side of a vertical.
Try it for yourself, try to use your hands to break a 1/8" carbon rod, just
past half way
