Thanks for all the kind words. I was a little worried goosenapper about putting it on the track but very pleased at how well it's held up. Like the SVRA slogan says, "Some people collect art, we race it!"
Mark, I made the cut just in front of the front magnet. There is nothing there between it and the circuit board. I used a razor saw. I rejoined it with CA glue then put a big fat bead of hot glue across the inside. The two white strips you see in the chassis picture are strips of styrene to further strengthen it. It's taken a couple pretty hard hits and so far remained solid.
