Hate to say it, but I'm more on Matt's dark cloud here, although I obviously hope this pans out.
I've had a few experiences with guys opening centers who had no real slot racing experience, and even tho this is not a center, the same lessons apply: if you don't have someone around who knows the basics, you're going to get into trouble very quickly.
The first time was about 20 years ago in a resort town on the Normandy coast, where a guy had opened a summer/tourist type place with a very nice 4-lane Fleischmann track, rented for 5 or 10 minutes at a time, with a car. But... the track was way too difficult for beginners and long enough that going to get your deslotted car was a PITA. Secondly, he had absolutely no idea how to maintain the cars, or even where to find spare braid, etc. Don't think that place was around next time I passed through.
Second was Le Slot Center that opened in Paris about 15 years ago, with a 6-lane Carrera track for 1/32 and an 8 lane wood track for 1/24 (Flexi type stockers). They did at some point in fact hire a slot racer who knew what he was doing, but then didn't keep their promises to him, underpaid him, etc., so he finally left. They actually did pretty well at the beginning, by the way, selling an awful lot of cars (it was a ritzy area of Paris, where the guys had money), and for awhile had a good turnout for the 1/32 races (Wednesday evening), but struggled to get a good crowd for the 1/24 - among other reasons because it was on Saturday night! I and the other married guys tried to explain this wasn't a good idea, but they didn't listen...
No, not exactly comparable to the situation here, but the constant is you need somebody competent to run things, sooner rather than later, and you have to treat them right and get them "invested" in the project, one way or another.
Slot cars are not bowling bowls - they wear out, need tuning, etc. And races have to be quick, fun and fair...
