 |  fw_iterm_throw_limit  | 165 | Limits max/min I-term value in stabilization PID controller in case of Fixed Wing. It solves the problem of servo saturation before take-off/throwing the airplane into the air. By default, error accumulated in I-term can not exceed 1/3 of servo throw (around 165us). Set 0 to disable completely. |
 |  fw_reference_airspeed  | 1000 | Reference airspeed. Set this to airspeed at which PIDs were tuned. Usually should be set to cruise airspeed. Also used for coordinated turn calculation if airspeed sensor is not present. |
 |  fw_turn_assist_yaw_gain  | 1 | Gain required to keep the yaw rate consistent with the turn rate for a coordinated turn (in TURN_ASSIST mode). Value significantly different from 1.0 indicates a problem with the airspeed calibration (if present) or value of `fw_reference_airspeed` parameter |
+|  fw_loiter_direction  | RIGHT | Direction of loitering: center point on right wing (clockwise - default), or center point on left wing (counterclockwise). If equal YAW then can be changed in flight using a yaw stick. |
 |  mode_range_logic_operator  | OR | Control how Mode selection works in flight modes. If you example have Angle mode configured on two different Aux channels, this controls if you need both activated ( AND ) or if you only need one activated ( OR ) to active angle mode. |
 |  default_rate_profile  | 0 | Default = profile number |
 |  mag_declination  | 0 | Current location magnetic declination in format. For example, -6deg 37min = -637 for Japan. Leading zero in ddd not required. Get your local magnetic declination here: http://magnetic-declination.com/ . Not in use if inav_auto_mag_decl  is turned on and you acquire valid GPS fix. |
