This table will grow as I find out more information about the motors out there. Obviously some of these are motors which do not apply to the 12-lb weight class or do not fit in the budget. I'm just throwing them out there to give you more practice.
Also, I have gathered these stats from different places, mainly:
Team Tentacle's Torque/Amp-Hour Calculator (A great source for calculating motor current draw, torque, acceleration, etc!)
Frequently the stats did not line up, both amongst themselves and with what I know (ie. Kt*Kv=1352). But they're usually fairly close, there could be a difference due to rounding and other slight things, or maybe just due to poor measurement. In any case, these are some of the numbers I found. I'm not sure which stats are right and where, so I just picked the ones that looked best to me. Suspend your disbelief long enough to try out some of the calculations you've learned!
