>>Mike, 18x24.. that's what Z was made for. I have a few Loco's in both >>Steam & Diesel. The show was yesterday, he went with a homemade dc motor made out of 6 wraps of 24 ga magnet wire, a magnet and a battery. It spun sometimes. Ended up with a 2nd place. thanks for the offer, if I was more prganized I might have got the note out a day before the show. thanks, mb
