I see where MRC released some sound decoders for Kato N scale diesels that they claim are shrug and pray plug and play. Has anyone tried these? Are they really drop-in? Do they perform any better than MRC's past N scale decoders?
I had an Atlas GP40-2 with an MRC sound decoder carved into it. The sound was weak and the engine ran like a spastic rabbit. It now has a silent Digitrax decoder and runs like da bomb.
Have MRC decoders gotten any better?
