correct gap between magnet and wire

[Keld]

What is the correct gap between the wire and the magnet in the steering?
some cars was loose in the screw so I could turn it with the fingers, and now I don't have the same gap on the cars, what is the correct gap in mm.?

Keld, The gap between the magnet and the wire depends on how good your track is!
You adjust the magnet down until it touches the highest point on the wire and then
raise it slightly. It is better if the wire is slightly higher than the track surface.
The card we supply is slightly thinner than the wire. If the wire and card are glued
down properly you have a perfect track. If your wire goes up and down, you will not get consistent steering.

Without a kaross.
Its easy to adjust the nuts for the magnet. I can see that one or one and a half mm at the the top will make it.
But ist easy to drive around and just lissening if it scraap in to the wire. The adjust the height!
Make som tools that not are magnetic.
