Thought I'd start a thread - although not strictly motor racing it sort of is related I think most would agree.
Back in the 60's I guess a lot of us couldn't afford real racing so slot cars were I suspect our "racing" outlet..
Still have my COX Lotus 30 and it has history - Pete Geoghegan drove it at the official opening of the Drummoyne Slot Car Club in the celebrity race. Years later I asked Pete if he remembered the night and he said "Suuurrrre ddddiiidddd" when I asked him if he remembered "driving" the Lotus 30 - he said no, but quick as a flash said "did I win" -- my answer "sure did". These things were pretty advanced, magnesium chassis and wheels, very light and very quick and very reliable straight out of the box.
Also have the shell of a Airfix GT40 I ran in a 24 hour race at the Sydney Society of Model Engineers, which is now located at Luddenham in Sydney's west, but in those days it was off Parramatta Rd, Ashfield next door to Peak Freans Buiscuit factory.
Slot cars back then were pretty big business, most large shopping centres had a track, and a lot of shopfronts put in a track and various clubs were formed, such as the Drummoyne one mentioned above.
