Which one had the biggest amp jump from being one or two degrees down? The biggest difference would be the kV. The problem with the Sky RC doesn't have a power regulator, so each motor was seeing a different voltage. Either way, it is almost impossible to tell which one has the most torque by looking at the RPM, current, and kV. Knowing the strength of the rotor would help break the tie. Also, this is the exact reason why WMH Racing made the Load Master.

One thing you could do is, run the tests while the motor is installed in your car. The car's drivetrain will add resistance. The car that has the less current draw will be the one with the most torque.
