Is there a "formula" to use to determine how large a diameter CF rod you will need for a given plane? I know length would be a determining factor as well as load which may be harder to determine unless you use the MFG's recommendations for servo size/oz. of torque.

I still have and use the Dave Brown pushrods.
Probably not liked as much because of the thickness.
Anyone using the Dave Brown pushrods?

We do it all the time for pylon airplanes. Here is a site that both sells the parts and explains how to do it: [link=http://www.darrolcady.com/Carbon_Fiber/carbon_fiber.htm]Darrol Cady[/link]
Scott Hartman does a good job showing it in a couple of his build threads:

I do mine the same basic way with a 1/8'' OD (.093'' ID) carbon rod, 2-56 (.093'' Dia.) control rods, 1/8'' ID aluminum tubing & JB weld. If you need a larger rod size, just take the control rod diameter, match it to the ID of the carbon rod, cap the ends with a matching piece of aluminum tubing and assemble it as shown in these examples.
Hope that helps some!

RE: Carbon Fiber Push Rods ??
Sorry PK, I should have said carbon tube (Hence the inner diameter & the outer diameter dimensions). The tubes seem stiffer than the solid rods to me, as I have both. The solid rods only really work in you use the solder link threaded couplers and attach them to the outside of the rods. (the couplers come in brass, steel & titanium). I feel that the solid rods flex more, and I don't trust the glue joint or the solder link enough. I have had the brass & steel ones both fail, and prefer the metal rods inserted in to the carbon rads with the brass or aluminum tubes over the ends.
sorry for any confusion!
