Who carries those Mr. Design gearboxes Jeff? Good point on the electronics too. I just hate spending over 300 hundo on two black boxes. I also found some metal wheels direct from Asiatam, but I cant seem to order anything on their site. I have hit the "add to cart" button a hundred times to no avail....65 euro is as cheap as I have found them and they come with the metal swingarms, anybody find them cheaper?
