To be fair to AE, they've been very good about keeping many old RC10 parts in production. It's great how I can still get brand new idler gears for the 6-gear, a-arms, hinge blocks, dog bones etc. Even the original 6160 body (or one very close to it) is still readily available.
True, many of the bits for the very early cars (like mine) are not still made, or at least not in white, but I've conceded to running the long front a-arms anyway.
Shock towers and tranny braces etc are still inexpensively machined here in the UK from fibrelyte - they even do a molded carbon tub!
And the bits that aren't still made, you can find very easily on eBay.
I have no fear racing my gold 6-gear RC10 with modern cars in club, regional, and national events...
Cheers,
Ty
