Here is an idea for a track. I plan to use it with two booster cars running 2.8 - 3.4 motors. Do you think the lanes are wide enough, or to wide? Also don't go by the proportion of the picture. I ran out of room. Look at the measurements for size. I plan to use a peice of wood as a base. Should I do anything to the wood or just use it as a surface? Also what are good barriers?
