Hi all,
Question posed recently was:
> Is the 9V-motor compatible with the 12V-motor?
Well, the 9v motor won't be compatible, unless you solder 4 pick ups on the
motor. This link may help: http://www.fgltc.org/bwoabs/9v_12v/9v_12v.phtml
It should show you how to convert a 9v motor into a 12volt one (after some
tweaking)
Just wonder if anyone has tried this & may have photos of such a project?
Thanks, Neil
