Oil of Wintergreen for tire goop! I still love the taste and smell of Wintergreen.
Cox, Russkit, Dynamic, Monogram, Champion. I did a 24 hour enduro with a P4 bodied car (Like Jim's) and used up a months worth of "disposable" income on blown motors. We only made it 16 hours before we ran out of motors and the track owner wouldn't extend us any more credit!
Dang, it was fun! And I didn't drive a slot any better than the real thing! Crash and burn......................
