I just bought a Ruby at the ECLSTS. What a lot of fun, even though it runs like a lunatic. It either stalls on a mild grade, or speeds like a maniac and launches itself off the first curve. I’ve been reading a lot about Rubies and there is a ton of info out there.
So far I have “adjusted” the safety valve so it blows off at about 45 lbs, instead of 20, and added a road pilot to the front. I’m planning to add RC–otherwise I think it will be unusable on my layout. I plan to add a Goodall valve and to reverse the eccentrics, because it runs much better in reverse. I’ll probably make a tender to put the RC receiver in.
Oh and yes I burned my fingers
