Andrew, thanks for your input. Right now I have a Digitrax DZ123 that I was going to use. Is it possible to obtain a USP unit or is that a special feature of the Lenz decoder?
The speeder comes with two work carts so I debated on placing the decoder on the cart like you mentioned and then covering it with a 'tarp' or something to disguise it, but decided against that to reduce the amount of wires going to the speeder. The trailing carts have metal wheels so I am working on putting power pickups on the carts to give the unit 12 wheel pickup instead of the original 4. I am planning on running the right rail pickup through the draw bars, and hope to disguise the left rail pickup as some kind of safety chain or something like that. Even if I cannot get a decoder in it, I am hoping that this will greatly improve its DC operation.
Right now my main problem is trying to figure out how to get the wires inside of the unit and isolate the motor without hacking it to death.
