The motor stall current @ 12 volts is the same regardless of what gearbox it may be attached to.

I spoke with Andymark and they put up the statistics for the motor inside the PG71 Gearmotor. Looking at them, they are rather puzzling:

PG71 Gearmotor Stall Current: 22 amps


RS775-5 Motor For PG71 or PG188 Gearbox (am-2161) stall current: 15.1 amps


If the Banebots RS775-5 is truly the motor inside the PG27,71,188 series gearmotors how can they have different stall currents? Either the numbers are wrong (likely the 775-5 as the gearmotor combo was empirically tested) or there is actually a different motor in the PG71 gearmotors.

For more info on why I'm asking, see the link to the Red Raptor in my stat; it's the wrist joint.
