ok after some extensive 3 week training i am now a monrail driver. hahah
so as noted in the monorail thread i am making a powered version of this.
My method will be to run track on the out side and have the monorail run on this as per normal nscale use.
It could be used for dcc as well and have block detection which is one reason why i chose this path.
Also as it's the easiest way to do it.
here is a quick vid of thomas running on track currently i am waiting on the screws
have you looked at the mechanism that the disney monorail guy did. it looks to be the cleanest design to make this work. gearing also to get the most torque out of a smaller motor.
i corresponded with the chap some when the greenmax monorail was first announced. he was interested in it and was willing to talk to anyone who might want custom mechanisms made for them. they aint going to be cheap, but it looks like he does very nice work.
