hi there need some advice ive been laying the foam road bed down on my drawn out layout i have 2 main lines the outside is a 22 in radius and the inside is 18 inch radius i used the sharpie and yard stick method to attain this. and the tplan is out of an atlas plan guide for a 4/8 ive strched it out to a 10 by 53 inch .my problem is before i completley lay down all the road bed i went to the lhs to get a remote turnout left and right to kinda see where my road bed should go but i noticed that the switching radius seems to be off a bit when i connect some flex to it it bends wrong and doesnt follow my radius do i have the wrong radius switchers ?? i layed my road bed right on the outside of my sharpie mark.id like to lay the rest of my roadbed but am now scared i might have to tear it up and start over is this somthing that is critical or can i lay it down and look for the right peices later.its basiclay 2 ovals with a reversing loop in middle with 2 90 degree crossings to some dead stops in middle with the ability to switch from out mainline to inner.atlas calls it the eagle route in ther trac plan guide..thanks for any help..
