I got another GP50 this time it is a NS shell. It came with a DCC decoder integrated into the main PCB. I replaced the PCB with a plain board and added my standard Zimo MX630 DCC decoder. The engine ran awfully :o
Be warned, the DCC version of the GP50 has hidden under the motor massive RFI suppression components (2 * R and 2 C) forming a bridge with connection to the motor housing. That made my DCC decoder run havoc at low speed.
You need to remove they RC element to run with standard DCC decoders!
ps. the engine has NO flywheels
