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
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 IC-2000™ available from
Bob Smith and the product that NHP sells under the name of Black
Flash. 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.
