is it alright to alter the fisher proce gearbox. Reason being is we need a light motor like the fisher price. But, it runs to slow for with the gearbox and too fast without it. Could we alter the box to our liking?

yep, i spent the entire day lathing a piece for a specific gear then sawing/sanding the gearbox down to fit only the gears I needed.. warning- be careful if you test the gears with a battery.. the fisher price is pretty darn fast, we toned it down to 600 rpm for a certain mechanism but upon testing it with a battery this mechanism *flew* out and hit our 12+ foot high ceiling
