The minute I put the ETO metal tracks on mine Bill the idlers bowed outward. I was able to straighten the hull. I've since removed the metal tracks and set them aside until someone came up with an idea. It wasn't the metal tracks fault however, they fit nicely. It is just a weak point in the JS-2. How did you attach your brace to the hull?

OK, I didn't see all of your photo's at first. I now see how it is attached.
