1:10 or 1:12 scale project wanted...

I know of no one which stocks the parts as of yet. You LHS might be your best bet for now. Or maybe eBay. Pickings will be slim for a little while. No matter what, this thing is going to require some custom parts, unless you find a hardened pinion to use with the steel spur.

Yeah MM is right; standard buggy bearings are 8x16. This one however is 10x15x4mm (the CRT.5 bearings are thinner). It's funny, because there are a lot of things that are 1/8 scale size ... almost. 8 scale works on many things with modifications.
