📄️ 3D Setup
This page is under construction and will be used to outline how to set up 3D mode on a multirotor and should list out the important and easily missed steps in order to avoid incidents.
📄️ Acro Trainer
Adds a new angle limiting mode for pilots who are learning to fly in acro mode. Primarily targeted at new LOS acro pilots, but can be used with FPV as well.
📄️ Arming Sequence & Safety
Switch arming
📄️ Barometer
Barometers measure air pressure to determine altitude. They are highly sensitive, responding to a breath of air, and are very temperature sensitive. Typically they incorporate accurate temperature sensors to provide compensation.

📄️ Buzzer Mute Mode
With Beeper Mute Mode you can silence the buzzer as long it's not needed.
📄️ Community Presets
The below presets are **by the community, for the community**. You will see the BF version the preset is targeted toward and the pilot's name who published their recommended preset(s). We encourage communitymembers to provide their own presets on this page. To do so, you simply need a Github account. Enjoy!
📄️ Configuring Crossfire
Betaflight has the ability to display on your OSD a measurement of Crossfire LQ (Link Quality). This measurement is based on a ratio of successful packets transmitted and received. This is the recommended performance indicator to use instead of RSSI, due to the overall signal strength of the Crossfire hardware.
📄️ Current Sensor Calibration
Some boards include a current sensor in order to provide measures such as "Battery current draw", "Battery current mAh drawn" and others. More often than not, the current sensor has to be thoroughly calibrated for the measures to be accurate. Also, Betaflight includes a Virtual Current Sensor feature that can be used when the current sensor is missing or broken. This sensor needs a different calibration procedure to be performed in order to provide reasonably accurate measures. The Betaflight documentation includes very valuable advice on how to calibrate both sensors: Battery

Description
📄️ Failsafe
If the radio link is lost, or the receiver fails or becomes disconnected, the pilot will have no control over their aircraft.
📄️ Feed Forward 2.0

WHAT THIS IS:
📄️ GPS Rescue 4.4
Betaflight 4.4 brings huge improvements in the altitude, velocity, flightpath accuracy and landing behaviour of the GPS Rescue code. The Sanity Checks that monitor the status of the Rescue are less likely to disarm the quad or falsely declare a failure of the rescue.
📄️ GPS Rescue 4.5
Betaflight 4.5 makes the following significant improvements to GPS rescue:

📄️ Mass Storage Device Support
Mass storage device support allows the micro SD card or the flash chip of your flight controller to be mounted as an external storage device on your PC. This allows for easy drag / drop download of log files.
📄️ Mixer Support
- Beginning with 3.1.7, some rarely used mixers have being dropped from F1 and F3 firmwares due to flash space limitation.
📄️ Mixer Types
All graphs below are representing AIRMODE enabled scenarios. When AIRMODE is disabled, regular mixer clipping on low throttle range will happen.

📄️ Rate Calculator
Betaflight supports different rates models. A rate model is the mathematics used to transform the stick position to a turn rate in deg/s. Three parameters, RCRate, Rate, and Expo, determine the curve of the rate model.
📄️ Remapping Motors with Resource Command
Necessity for swapping/shifting/rotating motor positions rises from time to time. Before v3.1, we had to either use long wires between FC and ESC to retain the original mapping (which make the build messy) or use a custom mix to change how each motor contributes to attitude adjustment.
📄️ Resource Remapping Command
NOTE: this command is only available in version 3.1 and newer of Betaflight.

📄️ SBus FPort and Open Tx
OpenTX has the problem that it fails to fully utilise the hardware that FrSky sells for SBus and FPort (called 'D16' in OpenTX terminology). As a consequence, on FrSky hardware that is perfectly capable of supporting 4 RC channels and up to 12 switch channels with an update rate of 9 ms, OpenTX (up to and including version 2.2.3 at least) only supports an update rate of 18 ms for the RC channels. To make matters worse, it does this by sending RC frames to the flight controller at intervals of 9 ms, but sends identical RC data for each pair of consecutive frames.

Introduction
📄️ Telemetry
Telemetry is information sent back to your RC transmitter via the RC data link. For example, telemetry allows for your RC transmitter to read out your main battery voltage or RSSI. For telemetry to work your RC receiver and transmitter must support it. The specific data that Betaflight will send via telemetry depends on the telemetry protocol being used. For example, Smartport will send a certain set of information while Crossfire will send another set.
