I watched the video. "An Introduction to FlyerChief S Gauge by Lionel" might be a more appropriate title. An "Introduction to S Scale" is somewhat misleading, (particularly as the Flyer 0-6-0 is oversized) as we all know S is much more complicated than a starter set.
He did a good job showing off the set's components and operation, along with a separate sale Baldwin. Couple of minor faux-pas, but nothing outrageous as he's working with something outside his wheelhouse.
