Well, I finally ran it tonight, pretty crazy! The 9L was overgeared at 16/49 (I think that's what the pinion was), so I bumped it to the 52 tooth spur and it ran great. It bombed up and down a dirt hill next to my house with ease, even flew across the grassy area at the top real quick too. System stayed stone cold during the short 3 minute run until the pinion set screw backed out.

Oh yeah, the wheelbase is between 14.5" and 14.75".....had trouble reading the little marks and keeping the front lined up with the middle of the wheel nut. My only problem with the body choices is that no matter what I get, it'll ride kinda high on the low slung chassis. Just so long as there isn't daylight visible though, that's one of my major annoyances.
