In the 1/32 world, since 1997 we've seen cars and tracks go digital, detail on bodies has been brought to a new high, and quite a few new manufacturers have emerged.
For 1/24 scale, between the late 90s and early 2010s, we've seen drag racing grow, retro racing has become a class, and collecting 60s and 70s cars is booming.
For all the scales, electronic controllers started showing up.
HO in the 1980s and early 90s had trucking, TCR and AFX, then the decline of trucking, TCR and AFX, the explosion of inline magnet car racing, and Lexan bodies became the norm.
I wasn't part of 1/32 or 1/24 in the 80s and early 90s so I can't really comment on that period, but I'd love to hear your stories.
What do you think we'll be seeing in the next 15 years of slot car racing? Digital HO? Mag-Lev? Wireless?
