Paul,

Dr. J measured 10A at 0.8V stall current on his 14T motor.
Team 177 measured 10A at 2.5V stall current on our 13T motor.

While I will admit that we did not measure the voltage right at the motor, I refuse to believe that we dropped 1.7V in the wires and connectors. I would guess more in the 200 to 400 mV range which puts our 12V stall current closer to the 60A indicated for 12V FP motors in the past. Whereas Team 47's motor has a 12V stall current closely matching the 150A specified for the 6V model.

I submit that we have different motors.

Regards,
