Gary Kato:
Thanks for your comments. I did my track prior to painting, doing the end pieces first then connecting them which worked out all right for my sausage fingers. As for the fit problem, I'll give you my philosophy with Tamiya; if I have a fit problem, I assume that I am screwing something up, because over time I've found their engineering to be much better than my limited brains! I do recall some problems with that part but eventually found a way to fit it so it was 'happy'.
