Speed controller bandwidth
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.

Motor spin direction as detected during initial enumeration. Use 0 or 1 to reverse direction.

Speed (RPM) controller gain
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.

Motor current limit in amps
Motor current limit in amps. This determines the maximum
current controller setpoint, as well as the maximum allowable
current setpoint slew rate. This value should generally be set to
the continuous current rating listed in the motor’s specification
sheet, or set equal to the motor’s specified continuous power
divided by the motor voltage limit.

Motor Kv in RPM per volt
Motor Kv in RPM per volt. This can be taken from the motor’s
specification sheet; accuracy will help control performance but
some deviation from the specified value is acceptable.

Motor voltage limit in volts
Motor voltage limit in volts. The current controller’s
commanded voltage will never exceed this value. Note that this may
safely be above the nominal voltage of the motor; to determine the
actual motor voltage limit, divide the motor’s rated power by the
motor current limit.
