### airmode_type

Defines the Airmode state handling type. Default **STICK_CENTER** is the classical approach in which Airmode is always active if enabled, but when the throttle is low and ROLL/PITCH/YAW sticks are centered, Iterms is not allowed to grow (ANTI_WINDUP). **THROTTLE_THRESHOLD** is the Airmode behavior known from Betaflight. In this mode, Airmode is active as soon THROTTLE position is above `airmode_throttle_threshold` and stays active until disarm. ANTI_WINDUP is never triggered. For small Multirotors (up to 7-inch propellers) it is suggested to switch to **THROTTLE_THRESHOLD** since it keeps full stabilization no matter what pilot does with the sticks.

### vbat_scale

Battery voltage calibration value. 1100 = 11:1 voltage divider (10k:1k) x 100. Adjust this slightly if reported pack voltage is different from multimeter reading. You can get current voltage by typing "status" in cli.

| Default | Min | Max |
| --- | --- | --- |
| _target default_ | 0 | 65535 |

---

### vbat_warning_cell_voltage

Warning voltage per cell, this triggers battery-warning alarms, in 0.01V units, default is 350 (3.5V)

| Default | Min | Max |
| --- | --- | --- |
| 350 | 100 | 500 |

---

### vtx_band

Configure the VTX band. Set to zero to use `vtx_freq`. Bands: 1: A, 2: B, 3: E, 4: F, 5: Race.

| Default | Min | Max |
| --- | --- | --- |
| 4 | VTX_SETTINGS_NO_BAND | VTX_SETTINGS_MAX_BAND |

---

### vtx_channel

Channel to use within the configured `vtx_band`. Valid values are [1, 8].

| Default | Min | Max |
| --- | --- | --- |
| 1 | VTX_SETTINGS_MIN_CHANNEL | VTX_SETTINGS_MAX_CHANNEL |

---

### vtx_halfduplex

Use half duplex UART to communicate with the VTX, using only a TX pin in the FC.

| Default | Min | Max |
| --- | --- | --- |
| ON |  |  |

---

### vtx_low_power_disarm

When the craft is disarmed, set the VTX to its lowest power. `ON` will set the power to its minimum value on startup, increase it to `vtx_power` when arming and change it back to its lowest setting after disarming. `UNTIL_FIRST_ARM` will start with minimum power, but once the craft is armed it will increase to `vtx_power` and it will never decrease until the craft is power cycled.

| Default | Min | Max |
| --- | --- | --- |
| OFF |  |  |

---

### vtx_max_power_override

Some VTXes may report max power incorrectly (i.e. 200mW for a 600mW VTX). Use this to override max supported power. 0 to disable and use whatever VTX reports as its capabilities

| Default | Min | Max |
| --- | --- | --- |
| 0 | 0 | 10000 |

---

### vtx_pit_mode_chan

_// TODO_

| Default | Min | Max |
| --- | --- | --- |
| 1 | VTX_SETTINGS_MIN_CHANNEL | VTX_SETTINGS_MAX_CHANNEL |

---

### vtx_power

VTX RF power level to use. The exact number of mw depends on the VTX hardware.

| Default | Min | Max |
| --- | --- | --- |
| 1 | VTX_SETTINGS_MIN_POWER | VTX_SETTINGS_MAX_POWER |

---

### vtx_smartaudio_early_akk_workaround

Enable workaround for early AKK SAudio-enabled VTX bug.

| Default | Min | Max |
| --- | --- | --- |
| ON |  |  |

---

### yaw_deadband

These are values (in us) by how much RC input can be different before it's considered valid. For transmitters with jitter on outputs, this value can be increased. Defaults are zero, but can be increased up to 10 or so if rc inputs twitch while idle.

| Default | Min | Max |
| --- | --- | --- |
| 5 | 0 | 100 |

---

### yaw_lpf_hz

Yaw P term low pass filter cutoff frequency. Should be disabled (set to `0`) on small multirotors (7 inches and below)

| Default | Min | Max |
| --- | --- | --- |
| 0 | 0 | 200 |

---

### yaw_rate

Defines rotation rate on YAW axis that UAV will try to archive on max. stick deflection. Rates are defined in tens of degrees (deca-degrees) per second [rate = dps/10]. That means, rate 20 represents 200dps rotation speed. Default 20 (200dps) is more less equivalent of old Cleanflight/Baseflight rate 0. Max. 180 (1800dps) is what gyro can measure.

| Default | Min | Max |
| --- | --- | --- |
| 20 | 1 | 180 |
