I need to make up some control rods and need some advice. I want to run a rod from the stick to the airleron bellcrank, then another rod back to the airlerons, so I thought of 1/2 inch or so aluminium tube, with a solid aluminium insert at each end which can be drilled and tapped, riveted or bolted in place, riveting would be better I think, then use a male threaded rod end bearing in each end with a left hand thread and a right hand thread respectively. I do not know a great deal about rod end bearings, and a part number of something to do the job would be very helpful. My biggest worry is what size of bearing would be needed to do the job, theres thousands of them in the catalog, but just don't know what an appropriate size would be as I have absolutely no experience with these types of bearings. Would 1/2 or 3/4 inch inch tube do the job, and what wall thickness would be strong enough?
