I deleted the high and/or low numbers and just grouped the 3 motors by relative AMP draw. Looking at this data, I would conclude that the KD-19 has less TORQUE, similar Watts & Efficiency. The C2 still seems to create MORE Power/Watts in a equal AMP draw test, but the KD-19 does have a TON more RPM.
