ABSTRACT:
Die-cut corrugated paperboard blanks define a closed looped oval race track. The blanks form a flat roadway surface which is supported on paperboard wedges at an angle to provide banked straightaways and curves for the travel thereon of radio controlled battery powered cars. A paperboard barrier formed of a plurality of folded corrugated blanks is engaged against the elevated edges of the roadway to prevent the escape of the cars from the race track. The blanks which form the banked curves of the roadway have a plurality of radial slit scores which facilitate the bending of the corrugated paperboard blanks to approximate a frustroconical shape.
