[:D]Hey MRXR Fans, I have a Question[?]I want to build a helix and it will be my first time in building one, I was told a formula that will help me with the deminsions,but my math sucks Is there a easier(but cheap)way to build one? How do I find the determind size that I need, I'm confused [xx(] I'm working in "N"SCALE if that helps, My second question is this, I have modern loco's SD40MAC DASH8 etc,how do I determind my radius for curves it seems like no matter how I build my curves it seems to be to tight for the loco's. I need help Thanks again,[:)] TrainsRMe
