I was worried about the elevator setup, too. I upgraded to 4-40 rods, and used a piece of scrap aluminum to make a set screw block to tie them together. the block is about 5/8" long and 3/8"x3/8" square, and I drilled 2 parallel holes for the rods, and secured each one with 2 set screws. I put flats in the rods where the setscrews hit after I got it adjusted. I'm not worried about it anymore. I finally maidened yesterday. The landing gear now has splits in the front, due to our bumpy grass field. I wonder if GP will replace it.
