 |  motor_pwm_protocol  | STANDARD | Protocol that is used to send motor updates to ESCs. Possible values - STANDARD, ONESHOT125, ONESHOT42, MULTISHOT, DSHOT150, DSHOT300, DSHOT600, DSHOT1200, BRUSHED |
 |  fixed_wing_auto_arm  | OFF | Auto-arm fixed wing aircraft on throttle above min_throttle, and disarming with stick commands are disabled, so power cycle is required to disarm. Requires enabled motorstop and no arm switch configured. |
 |  disarm_kill_switch  | ON | Disarms the motors independently of throttle value. Setting to OFF reverts to the old behaviour of disarming only when the throttle is low. Only applies when arming and disarming with an AUX channel. |
-|  auto_disarm_delay  | 5 | Delay before automatic disarming when using stick arming and MOTOR_STOP. This does not apply when using FIXED_WING |
 |  switch_disarm_delay | 250 | Delay before disarming when requested by switch (ms) [0-1000] |
 |  small_angle  | 25 | If the aircraft tilt angle exceed this value the copter will refuse to arm.  |
 |  reboot_character  | 82 | Special character used to trigger reboot |
