How much clearance between the bottom of the magnet and the top of the rail should there be ?

Oh! Great topic!! To close and would it actually slow the car down? To much and won't work. I would think you would need to take in consideration strength of magnet??

I try to keep about .020 between the rail and the magnet.
Traction magnet strength should also be considered. Some are so strong they
will slow the car. Scale auto makes a neo traction magnet for their G3 that is so strong that it will kill your
speed thru the traps. I have lost about 15 MPH with these on an Unlimited. You could easily run these
on the ceiling if you wanted. They also tend to bend the chassis if it is not stiff enough causing the magnet to
drag on the rail. Magnet size also makes a difference. If you have a gauss meter a tiny neo magnet will give the
same reading as a large one. The mass of the magnet makes a difference.

Thanks Dave, that gives me a starting point.
