Does anyone know where I can get resistor wheel sets from in Australia? If not where I can order them from anywhere???
Not sure in Australia, but I do know Logic Rail Technologies (makers of some awesome signal systems for model trains) has ready made resistor wheels. They will even make, by special request, wheel sets in varying sizes depending on your rolling stock needs.
Here is a link: Logic Rail Wheels
Here is the price list. $8.95 for a set of 4 resistor wheels is not bad at all. And it appears they ship internationally, of course for a bit more.
Hope this helps.
