If anyone has some experience with the Ashlin Design Helix (HO scale, larger radius) and/or the Easy-Helix, I would appreciate some thought on design, construction, stability. The primary goal is to shift trains from primary (upper level) to lower level return loop and staging. The 10-11 inch rise is more than adequate.
Alternatively
I have a 22 ft run to drop elevation by about 5-6 inches, so a nolix would be an alternative, but I would like to reserve that discussion for another time.
Thanks
Doc
