I always like to have a "Layout I'd like to build" winner at every model railway show, well this is the one from the Slot Car Swapmeet described yesterday.
A time trial rather than racing circuit, I recon there's a lot of fun in a small space here - a lot like Paul Marsall-Potter's "Shelfie" layout ideas.
In use, you'll be looking to improve your lap times. At first, just keeping the car on the track will do it. Then you'll have to get better at putting the power on for the straights and getting it off again for those tight bends. Reaction times are all.
Construction (of course I asked) involved routing the slot and then sticking copper tape around it. This stuff is flexible but achieving a smooth finish must still take a lot of work.
The board folds in the centre for carriage and storage, making this a handy home circuit that most people could own. Very clever indeed.
And yes, I had a go. I kept the wheels on the ground but can't claim to produced a great time.
