Don't be so sure. They may appear to be unbiased at high speeds, but the can be very different we tested to and found that the can be up to 25% biased). My team went on to further test the motors and found that the motors themselves are slightly (<2.5%) biased, but not otherwise different (also the position of IFI). A word of advise is to check your speed controller output, you speed controllers can be giving very different outputs even if the all have the same PWM input. Calibration does help speed controllers become more consistent, but also try to use speed controllers purchased at the same time to avoid manufacturing variation over time.
