I used to race RCs late 80s and early 90s. My brother and I started with a Tamiya Boomerang then an Avante. Eventually I got another Avante (an ex model shop owner tweaked one with a carbon chassis). We both drifted away from racing, but I had another bash a few years later and upgraded to a Kyosho Lazer ZXRR, but again stopped. Would these cars be competitive now or compatible with the latest batteries and motors? Or is there any demand if I was to sell them?
