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.

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. This determines the maximum
current controller setpoint, as well as the maximum allowable

Attitude Pitch Time Constant
This defines the latency between a pitch step input and the achieved setpoint (inverse to a P gain). Half a second is a good start value and fits for most average systems. Smaller systems may require smaller values, but as this will wear out servos faster, the value should only be decreased as needed.

Maximum climb rate
This is the best climb rate that the aircraft can achieve with the throttle set to THR_MAX and the airspeed set to the default value. For electric aircraft make sure this number can be achieved towards the end of flight when the battery voltage has reduced. The setting of this parameter can be checked by commanding a positive altitude change of 100m in loiter, RTL or guided mode. If the throttle required to climb is close to THR_MAX and the aircraft is maintaining airspeed, then this parameter is set correctly. If the airspeed starts to reduce, then the parameter is set to high, and if the throttle demand required to climb and maintain speed is noticeably less than FW_THR_MAX, then either FW_T_CLMB_MAX should be increased or FW_THR_MAX reduced.

Roll -> Throttle feedforward
Increasing this gain turn increases the amount of throttle that will be used to compensate for the additional drag created by turning. Ideally this should be set to approximately 10 x the extra sink rate in m/s created by a 45 degree bank turn. Increase this gain if the aircraft initially loses energy in turns and reduce if the aircraft initially gains energy in turns. Efficient high aspect-ratio aircraft (eg powered sailplanes) can use a lower value, whereas inefficient low aspect-ratio models (eg delta wings) can use a higher value.

Speed <--> Altitude priority
This parameter adjusts the amount of weighting that the pitch control applies to speed vs height errors. Setting it to 0.0 will cause the pitch control to control height and ignore speed errors. This will normally improve height accuracy but give larger airspeed errors. Setting it to 2.0 will cause the pitch control loop to control speed and ignore height errors. This will normally reduce airspeed errors, but give larger height errors. The default value of 1.0 allows the pitch control to simultaneously control height and speed. Note to Glider Pilots - set this parameter to 2.0 (The glider will adjust its pitch angle to maintain airspeed, ignoring changes in height).

Set the disarmed PWM for AUX outputs
IMPORTANT: CHANGING THIS PARAMETER REQUIRES A COMPLETE SYSTEM REBOOT IN ORDER TO APPLY THE CHANGES. COMPLETELY POWER-CYCLE THE SYSTEM TO PUT CHANGES INTO EFFECT. This is the PWM pulse the autopilot is outputting if not armed. The main use of this parameter is to silence ESCs when they are disarmed.
