I know this topic should prove interesting....
Just been having a look at my Scalextric JGTC Skyline, and noticed one stupid thing that had puzzled me for a little while. The tyres on the front of the car, were meant for the BACK of the car. They are the same width wheels front and rear, just the tyres that were on the front had a slightly higher profile.
The tyres that were on the rear of the car had the annoying tendancy to move sideways on the rim, but after swapping fronts to back and backs to front, it doesn't do that any more! Should run a lot better now!
So what things have you come across on a slot car that you've found absolutely stupid.
Cheers,
