|---|---|---|
| Gyro and D-term filters | 27 | Gyro lowpass, notch, dynamic notch and RPM filter settings, plus the D-term lowpass filters and the slider multipliers that scale them.... |
| PID tuning | 73 | P, I, D, D-max and feedforward gains per axis, the simplified tuning sliders, I-term relax, anti-gravity, TPA, throttle boost and crash... |
| Angle, horizon and launch modes | 20 | The self-levelling modes (angle, horizon), acro trainer, launch control and easy landing. They sit in the PID profile beside the gains... |
| Rates and throttle curve | 25 | Stick rates and expo per axis for each rate type, rate limits, the throttle mid/expo curve, throttle limit, and the RC deadbands and yaw... |
| Motors and ESC | 23 | Motor protocol (DShot, PWM), bidirectional DShot, motor poles and idle, 3D mode, the mixer and crashflip, dynamic idle and the ESC... |
| Receiver and RC link | 32 | Serial receiver protocol and inversion, channel ranges, RC smoothing, RSSI source and scaling, and the SPI receiver settings for boards... |
| Failsafe and arming | 14 | What the quad does when the RC link drops (stage 1 delay, stage 2 procedure, throttle), arming angle limits, auto-disarm and... |
| GPS | 14 | GPS module protocol, constellations, SBAS, home point rules and the GPS lap timer. |
| GPS rescue | 12 | Return-to-home on failsafe or switch: return altitude and speed, climb and descent, sanity checks and minimum satellite count. |
| Autopilot, position and altitude hold | 66 | Altitude hold, position hold and the autopilot navigation settings of recent releases: hover throttle, position and altitude PIDs,... |
| Battery and current sensor | 28 | Cell voltage limits and warnings, voltage and current sensor scaling, and battery profiles where the release has them. |
| OSD | 49 | OSD units, warnings, alarms, stats and the display port settings for analog (MAX7456) and digital (MSP DisplayPort) video. |
| OSD element positions | 90 | One `osd_*_pos` value per OSD element. The number packs the element's column, row, visibility per OSD profile and variant into one... |
| VTX and camera control | 12 | Video transmitter band, channel, power and pit mode, the low-power disarm rule, and camera OSD control over the camera's own wire or... |
| Blackbox and debug | 20 | Blackbox logging device, sample rate and which fields are logged, plus `debug_mode`, which picks what the four debug channels record. |
| Telemetry and serial | 44 | Telemetry back to the radio (CRSF, SmartPort, FrSky, HoTT, IBUS, LTM, MAVLink), serial port options and MSP. |
| LED strip and beeper | 12 | LED strip colours, profiles and race colour, the status LEDs, and the beeper and its DShot beacon. |
| Sensors and board alignment | 35 | Accelerometer, magnetometer, barometer, rangefinder and optical flow, gyro device selection and calibration, board and sensor alignment,... |
| System and hardware | 25 | Scheduler and task statistics, buses (I2C, SDIO, USB, CAN), flash and SD card, PINIO, stats counters, pilot and craft name, mode... |
