hi
i'm new at this... I was wondering about the different radios and what will be the smallest circumference.
also i want to make a railroad with elevation and i would like to know what would me the maximum inclination.

cool
i just started on this
but someone told me that DCC is a lot better than dc, so even I just got my first set. I was thinking to covert it to dcc.
I bought today a bachmann set "the Explorer" with a diesel EMD F9
do you know if would be hard to do that one?
now what about of running a dcc locomotive with a dc controller is that ok?

can you convert any locomotive from dc to dcc?
