Terry I really like the carbon rod over the 4-40 rod, what size carbon rod do you use? You build vids are great keep it up

Thanks for the instructive videos Terry!

Always nice to see the various hardware choices, tips and tricks.

I get them from a kite supplier, they seem to be the cheapest I can find. Specs are on their page so you can order with the correct ID / OD to suite your needs. I don't recall exactly which one I have, I bought about 20 of them so I'll be good for a long time. https://goodwinds.com/carbon/pultruded-tubes.html

Been doing that on pattern planes where the lengths can be odd

I actually prefer to make my own pushrods over titanium rods many times. Always a perfect.

I used to do the hollow carbon rods with the 4-40 titanium ends. Very strong and light. But now I'm an old lazy and just use whatever is in the box as long as it wont bend like a noodle.

I did that on a pattern plane. Rods pulled out on an aileron, caused flutter and a crash. Small weight gain for threaded rod coveted by carbon

That happened to a few guys I know of also. But they used CA to glue the rod ends in. I used JB weld. I would not do them with a big gasser. Just a trust factor. I did have success though with smaller planes and even the 30 cc Edge I dumbed thumbed to the dirt.

Mine were JB welded wire in. Even sanded everything and cleaned it before gluing. Just wouldn't trust that setup anymore

Terry, sorry if I missed it, where did you get your bonded washers from to mount the stabs? Also, what length screw did you use?
