Hi, nice little buy that, I was watching it and forgot to bid lol.
To me it looks like the ultima scale series chassis plate, then been turned into a buggy, it’s long wheel base I’m sure of it. As for hop ups etc, there isn’t much about but that could all soon change with the re release of the mk1 ultima coming out in the next couple of months.
Top deck definitely looks home made, you mite be able to find one from the scale series on eBay, and may the turbo ultima 2 top deck should fit.
As for wheels, Jc racing now sells wheels for the ultima cars in 2.2 inch.
If your on Facebook come and share it on the kyosho ultima series page.
