Hey. All those years in boats we never saw a horizon, so it must be, right? I use what works with minimal futzing around. Conventional track power or straight battery r/c (none of that dcc carp jammed into it). 1911, and not an A-1. Flathead Fords. Vacuum tube radios. Even have dial phones in a drawer. XP Pro. Scotty said it very well...the more complicated you make the plumbing, the easier it is to stuff up the drain...or something to that effect.
