No load currents are a good way of comparing efficiency of two very similar motors. The lower the no load current, the better.

My CC 2650 draws 3.0 amps at 11.9 volts at both 0 and 10 degrees timing (i tested this using my eagletree brushless motor rpm sensor)

According to the datasheet at castle, the neu 1.5D and 2D draw 3.0 amps and 2.3 amps respectively at 10 volts. Too bad they don't have that number for he 1Y but it should be somewhere between the two or around 2.5 amps @ 10v. I'd take the CC build over the neu any day though despite the very slight efficiency difference if any.
