A closer look at the 1991 Marchon HO slot car concept track – Sky Fighters. To Kool for Skool ?!? Wishing an doing are not the same thing. For a slot car set, it is a very complex to assemble. The risk of breaking parts is high. Then the cars do not run well with the jet bodies. The bodies add a lot of weight and make it difficult to drive the cars. It doesn’t turn out to be any sort of ‘combat game’ with both lanes running. One car always seems to be stuck somewhere or off the track so there is no continuous rhythm between players. But, the box art sure is cool !!
