Hi all I am building an HO drag strip and don't know what to use for the power rail. I need something in a continuous roll as I need 90'-95' of the stuff 
Not sure it would matter since your going for speed and not handling and of course magnetic rail does add drag to a car so non magnetic wire or rail would be a better choice I would think.Crimnick said:I been thinking about welding wire....not sure of the magnetic properties though...
