Yep, you're right Del, concerning your "Critter Controls". Del.
In terms of "chasing" manually-controlled live steam, in my own case, that
definitely applied to my Ruby # 11 2-4-2, which down my 3% grade turned into a
150-scale-MPH "Acela-wanna-be"
&
wrecked spectacularly
several times until I finally got around to installing a "Spektrum" RC system in it this past year.
The Shays were an entirely different animal
-
nice & sedate
both up-&-down grade
with or without RC.
