This is important... to choose the right motors for the right jobs, and to figure out gearings and such we need to know motor specs. Preferably stall torque, free RPM, torque vs RPM curve.
Specifically the new drill motors vs "chalupa" (if thats how you spell it). Which has more torque, what are they RPM's? Which is better to use for drive train, what are the RPM-torque curves?
ACK
