That is the Championship Edition Box. I thought it would of said on one edge of the box along with part number.
The Championship Edition had the longest production run of any of the other RC10 models.
1990-1996. with it starting with white nylon parts, then going to black and white then to complete black nylon parts towards the end of production.
Dependent on kit when opened you did not know what kit you would get. Different shock tops, spring adjusters,wheels to name a few would all be totally different.
