If my math is correct, a slot car that sold for $10.00 in 1965, adjusted for inflation, should cost $78.05 in 2017. I can walk into my local slot shop today and buy a base RTR JK21 w/ hawk 7 and painted body for $79.99 -- and you know this car is light years past a 1965 Cox car -- or a whole outfit with plastic box, controller and oiler included for $114.00 A self-built retro car can easily come in at a little over $100. My simple point is that trying to source a $30 doesn't seem to be the issue in a "revival."
Going between tracks? I've just started racing with Retro East, which races at five different tracks -- plus most of those tracks have home series, too. Since these series follow IRRA rules, there is no problem with interchange, Next year's Penn-Jersey flexi series will race at six different tracks, up from four this year. Go to any of these races, and plenty of friendly racers will give you tips on tire choice, guide depth, some set-up hints. I was blown away that John Gorski gave me a lot of his time on a practice night last month. In addition, most of the tracks I have searched on the "net" have their local rules posted for their home-grown series, which means you can maybe adapt an existing car or, what the heck, build one! It is a hobby, right? What's that? They mainly race fairgrounds cars on their oval? Well, do you want to race and meet friends or not?
So I'm not sure what kind of a revival is being sought, other than trying to re-create the boom before the bust of the 1960's. Agreed, there aren't as many tracks. At least on the east coast there seems to be a very gradual upward trend. As you know, I came to the defense of Trains and Lanes in Easton, Pa recently. This year racing came back with Group F. Next fall we will add LMP racing which, with a body switch, can race in the Penn-Jersey Nastruck class. Plus, we will host that series twice. From what I see here on the blog as well as in my late-night surfing, I think this is a country-wide trend. Slow and steady wins this race.
You want to see more kids involved? Then the next time you are doing your serious thing and there are some kids on the rental track, or kids with their old flexis on the track, take the time to show an interest in them. There are many times when a family stopped to watch the cars go around that I have invited a kid over, put a slow (or expendable) car on the track, put my hand on his on the controller, and after a few laps he goes away beaming, and the parents are more than grateful. That's how a new racer is born.
Thanks for reading.
