In the Full Dome car referenced, you use two PTC's.  I'm confused since it seems in the text above you use a single PTC.  Please clarify.

Thanks.

I put one in the frame connections between the trucks as well since the chassis is plastic and there's no connection.  You'll notice the red and black wires between them, black for wheels, red for rollers.
