Landon,
Think of your P1 engines as a conventional engine that talks, the only way you can run it with remote control is with the full DCS, Z4K and side receiver. The DCS hand held remote control can then run any conventional engine on track power, from the DCS hand held remote control. The DCS Commander was not engineered to make this happen. The DCS using the Z4K with the side receiver is a much more complex engineering package than the DCS Commander.
