Zig, that is the Blue Emerald slot car, entered in one of the first Thingie proxy races.... It became rather infamous for being uncontrollable and a real PITA to drive!
I had the brilliant idea of pairing that shell with a 26D-powered 4WD chassis I had picked up on the internet, adding opposed hinged body mounts (over the top of the motor), thinking that would help, but without any testing, it just made it incredibly squirrely! Not to mention that marshalls couldn't tell if it was coming or going...
Don't think I've ever been as cursed out on a slot track as I was that year - but at least Swissracer was impressed, because he offered to buy the car from me! (maybe for target practice, who knows?)
