Have got a Centro C4.1 that I was going to advertise soon!
Only done one indoor Maritime Raceway meeting, built from new B4.1 kit plus new Centro conversion kit, can be supplied with new, clear bodyshell and some spares and wheels.
Also left over parts from B4.1, Rudebits brass understeering and chassis weights, X-Factory/Cream carbon front shock tower and alloy mounts, Ghea (I think!) brass front pivot block and black anodised aluminium pivot brace, B44 blue anodised aluminium battery posts, aluminium servo posts.
Pm email address for comprehensive listing and photo's!
