 | -------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------- | ----------------------------- | ------- |
 | `crash_recovery`           | Enable or disable the crash recovery feature.                                                                                                        | `OFF`, `ON`, `BEEP`, `DISARM` | `OFF`   |

-| `crash_gthreshold`         | Sensitivity threshold based on gyro readings                                                                                                         | `100` to `2000`               | `400`   |

+| `crash_dthreshold`         | Sensitivity threshold based on D-term values. Higher is less likely to activate crash recovery.                                                      | `10` to `2000`                | `50`    |
+| `crash_gthreshold`         | Sensitivity threshold based on gyro readings. Higher is less likely to activate crash recovery.                                                      | `100` to `2000`               | `400`   |
+| `crash_setpoint_threshold` | Activation threshold based on stick position. Setpoint must be under this value to trigger crash recovery (in deg/sec commanded).                    | `50` to `2000`                | `350`   |
 | `crash_recovery_angle `    | Defines the angle to which the craft will try to recover.                                                                                            | `5` to `30`                   | `10`    |
 | `crash_recovery_rate`      | How aggressively the craft attempts to recover. Higher values mean faster recovery but can lead to oscillations if set too high.                     | `50` to `255`                 | `100`   |
 | `crash_limit_yaw`          | Limits the yaw rate during recovery to prevent yaw spins. If during crash recovery the yaw rate exceeds this value, crash recovery will be cancelled | `0` to `1000`                 | `200`   |
