Ok, I got the fuel tank mounted, that was a PITA, because in typical ARF fasion, it's a tight squeeze to fit in, and they don't really have much provision for foam insulation. The instructions talk about using styrofoam from the packaging. I used the soft foam block that was used to pad the rear of the fuse. It's no styro, but a closed cell soft foam. Cut it into various blocks to line the cavity as best I could. Seems to work OK. It's wedged in there pretty good.

Mounted up EVERYTHING except the decals, and checked the balance. It's bang on, within the accuracy limits of GP balance jig. No weight needed. Radio and battery should be dead center in the fuse. Sweet.[8D]
