Hey Mark --
Thanks for the tips!
I need to retime my switch so I think I'll try out your method the next time.
I don't know about adding additional cells, though. Aren't you afraid of
burning
out the little DC motor?
Anyway, I'm pretty happy with the two entire 9 volt battery pack cells. An
additional
bonus was that when I dissected the plastic battery pack I found that the lowest
"cell"
was a piece of styrofoam which was removed making it that much easier to fit
inside
the M18v Control Back 2 where space is quite limiting.
