After our Indy Womp race at Bloomsburg, PA tonight, a racer put a newly built 3-D printed Womp on the track. We run 2.8 - 3.1 bottom to top on the oval. After 5 laps he was already at 3.1 mid-track. On the sixth lap he de-slotted, went over the wall, hit the floor and broke the guide tongue off. $15 chassis is trash. Not sure what the concept is behind a plastic slot car chassis for commercial tracks (I hear a 3-D flexi also is out there).
3D Womp - for what it's worth

Got to run it in 'modified/braced classes' -- epoxy a steel guide plate on top.
Not a flexy angle winder, but an FCRish clone.

Actually, the 1/24th scale chassis from Shapeways that Steve Grider designed is quite substantial. We tried to break one of his
prototypes, and it took a real effort to do it. I tested a production version, and reported on it on this site. Set up as a retro Can-Am,
it wasn't that far off the average time for a brass-and-wire version at the time. As I said back then, there was a real possibility
for a class of their own. I have a 4.5 inch NASCAR version to test, I need to get my rear in gear and do that. If FCRs are going
away, certainly could take it's place if it shows to be competitive.
The bottom line for the plasti-womp is it needs some engineering refinement. You just can't copy a steel chassis in plastic and
expect it to be the same.
