I've been thinking about dumping most of my O27 stuff and going to N gauge models. I've also gotten an HO set for my daughter for Christmas but the thought has crossed my mind to take it back and get her an N gauge set as well. It just seems like we could do so much more with N gauge considering the limited space we have. (Building O27 layouts on a 3x6 door is rather confining.) Any tips to "downsizing" so to speak? How easy is Flextrack to use as far as doing layouts? Can it be cut to length if need be? How tight of a radius can I get with N scale track before I have to worry about derailments?
