    <parameter default="75" name="ctl_bw" type="INT32">
      <short_desc>Speed controller bandwidth</short_desc>
      <long_desc>Speed controller bandwidth, in Hz. Higher values result in faster speed and current rise times, but may result in overshoot and higher current consumption. For fixed-wing aircraft, this value should be less than 50 Hz; for multirotors, values up to 100 Hz may provide improvements in responsiveness.</long_desc>

      <short_desc>Speed (RPM) controller gain</short_desc>
      <long_desc>Speed (RPM) controller gain. Determines controller
            aggressiveness; units are amp-seconds per radian. Systems with
            higher rotational inertia (large props) will need gain increased;
            systems with low rotational inertia (small props) may need gain
            decreased. Higher values result in faster response, but may result
            in oscillation and excessive overshoot. Lower values result in a
            slower, smoother response.</long_desc>
