I use 4-40 rod that slides into a piece of carbon fiber tube without twisting it in. Then I get some fine sewing thread and wrap the threaded rod for about 1/2 inch until it barely slides into the tube. Then I soak it in medium CA and shove it in. Works great, has never failed, is very simple, and done in less than 5 minutes. I have physically tried to pull it out and cannot. I have used this method on every pushrod on 2 different 50cc 3D planes without a problem. However, I have had some split when trying to thread rod into CF tube. Good luck!
