I've ordered th GM10 geared minimotor from solarbotics.
I know some of you have used it before.
Mine haven't arrived yet, so I'm still dreaming about it.
Here's a quick question for those who know it;
How big a wheel can I connect directly to the output shaft on the GM10 without any significant loss of power. I see they ship it with an optional 25mm wheel, is that the biggest recommended diameter, or can I go bigger without gearing it down further?
