Hello does any one have a helix that has been done trying to had yards to the ends of the Mojave sub but I need a helix to do this.
 
A helix is just a series of circles, @ the size of 1 baseboard, with a gradient of much less than 2.00% (a 1.00%, or less, would be recommended)
 
A railway track "helix" is also commonly called a "spiral" although in the majority of cases neither term is a strictly correct description.
