Not for the faint hearted, It has to be done during construction.You can't power a kit that has been assembled.I attempted one a few years ago,but gave up and sold it as a started project.
Thanks for the info. I also have the pages of mods for the kit so it runs better ,might even try them out on a couple of my MDC kits as they look similar.
your avitar shows a shay builders plate do you own one?
