Even after you tighten the plastic hinge pin holders or rc adjusters to the aluminum blocks, you still might have to loosen the aluminum mounts via the screws thru the chassis, and then give each of the arms a slight tap with the handle of your wrench, then re-tighten the chassis screws. I had the same problem and this was the fix. I think if you tried 12 different arms the problem isn't with the mold, that seems pretty consistent.
