Hi Rusty, I did it just like number 1 above. This way, if one bolt wants to loosen, it would tighten the other one. I had never done this before, but yesterday, my buddy Kyle, came over to visit me, and say his farewell. He did his 8 years of service to our Air Force, and now, time to head back home. We will miss him, he was an Advanced Pilot, and he flew with us last year in South Central. Now, he is going back to the South East Conference. In any event, we were out back, and I was telling him how I just drilled the screw heads, and then, he enlightened me, on how this safety wire works, and boy was I glad he told me, since I had no clue about this. Thank you for posting that as well, as it can be used as reference for others (and myself in the future!).
Regarding the threaded rods, those are fully threaded rods, meaning, it is the whole length of the push rod, all i did was slip a carbon fiber tube over them. this will help strengthen them against flexing. SO they are heavier, compared to had it been hollow. I just do not trust a rod that would have been glued on like that, on such a big airplane. Plus, I need tail weight to counter the nose weight. SO it is functional weight.
