    KV is a term to represent rpms per volt

    3500kv = 3500 motor rpms per volt
    3500 @ 11.1v = 38,850 rpms

    Kv rating alone will not tell you how capable a motor is, it will simply give you an indication of the speed you can expect to reach on a certain voltage

    A motors size / power rating is more important in determining if it will be suitable
