from the 1994 instruction manual:

Your new RC10 World's Car includes all of the newly designed parts our Team has been using that have helped us win four of the five 1:10 Off Road World Championships ever held. We feel there is no better car available.

As great as the existing Team Car has been, we know we have to continually work at improving our car so we can stay ahead of our competition. This car will show you that we have been busy working on a number of important upgrades. While the new car looks similar to the old car, there are many new changes. The new car starts with a black, hard anodized aluminum chassis made from a new material which is stronger than our original chassis, and it comes with the bottom of the chassis already milled out like our Team uses.
