A few years ago I read an article on how to convert the spectrum shay to R/C battery control. I did this using an old R/C set I had. It worked fine. and I would not have thought to isolate the track by removing the BBs that transfer the power from the wheels to the chassie.
Question. Does anyone know of similiar articles for the spectrum 2-8-0 and the Spectrum 2-6-0 mogal? This time I want to keep the track power as my layout is indoors, but I need to impose R/C speed, power, and sound control.
