If money wasn't an option I would have a fleet of full scale

I put well over 100lbs of force on my rod setup and it held. this was in the pull direction. Being that they are short(4"-5") they are also very strong in the compression direction. I am sure that the longer the rods are the weaker they are in the compression direction. I did not try to bend them in the middle as the rods will never see this force on the plane. I am cutting the rods to full length and utilizing all the threads in the ball end for extra strength as well. My 33% Waco weighs in excess of 60lbs fully loaded and I am fully confident in these rods holding.
Build one and test it out.
Just my .02
