## What it is
Betaflight is open-source flight controller firmware for multi-rotor and fixed-wing RC craft, written in C for STM32-based boards, focusing on flight performance and wide hardware support. It is accompanied by a cross-platform configurator application for configuring and managing the firmware.

## Use cases
- flash firmware onto an FPV drone flight controller
- tune PID and filter settings for quadcopter flight performance
- configure OSD, RGB LEDs, and VTX settings on a racing drone
- set up serial RX and telemetry protocols like CRSF and SBUS
- log blackbox flight data for tuning analysis
- configure a fixed-wing craft running Betaflight firmware

## When to choose
- you fly FPV racing or freestyle multirotors and want cutting-edge flight performance
- you need broad support for STM32 F4/G4/F7/H7 flight controller targets
- you want in-flight PID tuning, rate profiles, and rich OSD features
- you need an actively maintained, community-supported firmware with wide ESC and RX protocol support

## When to avoid
- you need long-range or autonomous mission planning features better served by ArduPilot or PX4
- you fly camera drones or consumer platforms with locked firmware
- you require certified or safety-critical autopilot functionality
- your hardware is not an STM32-based flight controller supported by Betaflight targets
