4200 Undercarriage

[Claus]

I do not own a 4200 or have any interest in one. I have read where some of you guys have had trouble with the tracks or undercarriage, I seen this on eBay, not sure if it is stock or an upgrade but thought somebody might find it helpful.

The seller states that it is a undercarriage for the 4200XL, but it's actually the original undercarriage of the 1:12 KAT machine, a different fabricator. Doubtful if it's a direct bolt-on scenario here to the 4200, but the overall dimensions are not that different..Anyway it's a good starting point for DIY projects.
