Hey guys!

I'm trying to get a gear I can put on the output shaft of this RG90 DC gear-motor that I need for a senior project type thing.
Problem is, I can't find very much information about the gear motor at all; no data sheet or anything, and I can't find any spur gear that fits the output shaft size on this motor which is 3.5 mm in diameter.

If any of you have used this motor and you know where to find any of this, It'd be greatly appreciated. Thanks.

Do you mean the RG90 here (http://www.trossenrobotics.com/rg90-gear-motor.aspx), and its technical drawing (http://www.trossenrobotics.com/shared/images/productdownloads/RG90-Gearmotor.pdf) with main electrical/mechanical specs (WHY?!?!? Torque is not 'kg/cm', it is 'kg-cm'; torque is equal to 'force times length', same units as energy)? Probably not since that one has a 7mm OD shaft with double flats (yet no measurement of the thickness across flats, or length of flats) intended for compatibility with solarbotics plastic gearmotors.
