You will know, if you follow my YT channel ( www.youtube.com/c/MyHotWheelsCollection ) that I have been running my own KOTH tournaments and more besides for some time now. Looking at the KOTH set up I currently use, this is a combination of the 6 lane raceway (I only use the centre four lanes) and orange track pieces to give 21' of track (a scale quarter of a mile, near enough). Now the thing I find is the need to set the track up and dismantle it each time, take over the lounge and the dining room and the need to be constantly getting on my hands & knees to reset the track, collect cars etc.is, if I'm being blunt, a pain in the ass, so a better, more permanent, solution was needed, After some negotiation, I gained permission from SWMBO to erect a shelf along the wall of the garage that will allow me to have a permanent set up that will eliminate all the problems outlined above, the only downside is I only have a maximum of 16' to play with. I will do away with the six lane raceway as this take up 8' of what's available, instead opting for a 3' high ramp that drops over 5' before entering the flat run to the finish gate, total track length will be about 15.5 feet. So I'll lose some of my length, but I honestly think, the plusses to doing this will outweigh this one downside.
I'll post some pictures here when construction gets under way (this coming weekend).
