A couple quick ones -

Weight of the wheels?

Thickness of the gears? (and weight, but I can calculate close enough)

Verify 32 diametral pitch on the gears (is the 120 tooth gear 3.75 PD?)

Thanks
Travis is surely not the only one with an FTC mini kit handy, as at least 800+ other teams have ordered these.

Did you know that the gears were "Assembled in USA"? Probably the reason behind the cost.... Go go gadget globalization.

Mr. Ruler sez that the 120 tooth gear's PD is 3.75", and its thickness is 0.25"-ish.

Mr. Scale sez that the 120 tooth gear weighs 114.71 g / 0.25 lb. (in its thin plastic packaging - didn't want to mess up the shiny finish).

Mr. Scale also sez that the 4" wheel weighs 117.24 g / 0.26 lb.
