David - thank you for the observations on the car - it is definitely appreciated!
You are correct on the main rails, I made them from roughly .120" thick steel. It was one of those - "had it sitting here" in the scrap bucket from a non-slot car project and had no piano wire on hand to start chassis attempt #2.
I'm sure those "robust" rails make up the majority of the weight though, as believe it or not, there isn't any lead in it! It is just those rails and the brass guide tongue material (doubled up, up front to get the thickness to use the Scalextric guide).
I "think" (could be wrong) - but if you are seeing the "grey" stuff sitting on top of the steel rails, and thought that was lead, that is just double sided tape (had to go a couple layers) that I used to attach the body to the frame. :)
On the tires, I figured that the Carrera Go! tires might not be the best, but I had them on hand, and figured maybe the less bite/more slide might be a good thing...
Unfortunately though, it sounds like they slid a little toooo easy. I guess on a positive note though, between the weight and the lack of grip, she didn't seem to have any issues with "tip" during the racing! :D
Did the gearing seem about right? Or was she still accelerating all the way into the corner? I went 10-26 on the gearing, trying to make up for the short tires - but afterward, thought I may have gone a bit overboard - considering how short the straights are on these ovals and not knowing how much torque these little slim lines have. (I was using the 9-26 with taller tires that I use on the local road course as a reference - but have more motor in front of it though)
Again - definitely appreciate the feedback - figure that is all good info for my next entry!
