PushRods are carbon fiber tubes. We stock three diameters and
they are the best PushRods we have ever found for RC applications.
They are lighter than the 1/4" square balsa we used to use
Each size has a use in different applications. They all work great.
They are used for racers as well as the Giant Scale airplanes.
The hole in the center of the 1/8" PushRod is a slip fit for a
2-56 Dubro threaded rod (not All-thread) and the 5/32" PushRod
is a slip fit for a 4-40 Dubro threaded rod (not All-thread).
The 3/16" will accept 4-40 all-thread. The threads are an excellent
gluing surface. In the instructions, we will show you several
ways to connect different fittings.
Before you install any metal fitting in any PushRod, clean the
metal fitting with a solvent like lacquer thinner or whatever
you have in the shop. Then sand the metal fitting with a rough
grit sand paper to scratch it for good glue adhesion. We have
found that medium cure epoxy, slow cure Ca, JB Weld all work very
well. We have just tested the new Rubberized Ca 2000 available
from Bob Smith and the product that NHP sells under the name of
Black Flash may be the best of all. It is fast and extremely strong.
Plus it does not get brittle and should never break from a shock.
We also have a product that is perfect for flying wires. It is
.060 x 36" solid carbon rod. A 1/16" Dubro threaded coupler and
our recommended glues make a perfect attachment. They are small,
light, and extremely strong in tensile strength. They will not
stretch! When you use the Dubro threaded couplers, thoroughly
CLEAN the INSIDE of the hole before you glue the rod in. Some
of them still have machine oil in them and no glue will bond to
the oil surface.
