Yes, and yes. Platinum aye? Spinner is a very "upscale type symet" I suppose
:). Now that I think of it, the motor exhibited other traits as well. The
lock up would come after placing the solar cell very close to the light
source. When the engine fired the thing would spin as if it were attached to
a 1F cap instead of the 4700uF cap it was hooked to. Then it would not cycle.
I chalked it up to an internal cap since the list was discussing that at the
time. I'm gonna have to look at this motor again.
