    KV is the rpm constant of the motor - it is the RPM the motor will spin when 1V (one Volt) is applied with no propeller attached to the motor.

    yeah, we figured that out, the only question left was what do the letters K and V stand for?

    A brushless motor doesn't spin at all with whatever DC volt attached - it requires a 3 phase alternating current, and the frequency of this rotating field gives the RPM of the motor.
    So, what exactly does this KV mean, if the motor doesn't spin at X Volts?

    K = Coulomb's law
    V = voltage

    I think Kv is just the Si name, that doesnt stand for anything but algegbra
