Betaflight Beginner’s Setup Guide
From flashing firmware to basic configuration
Betaflight is the most popular open-source firmware for FPV drones, offering precise control, advanced tuning, and a huge community for support. Whether you’ve built your first drone or bought a ready-to-fly (RTF) quad, you’ll need to configure it in Betaflight Configurator before taking to the skies.
This guide walks you through the essential steps — from flashing firmware to your first flight-ready setup.
1. Install Betaflight Configurator
- What it is: A free desktop app that lets you configure your flight controller (FC).
- Where to get it: Betaflight Configurator on GitHub or the Chrome Web Store (older versions).
- Tip: Always download the latest stable release unless you have a specific reason to use a development build.
2. Connect Your Flight Controller
- Use a USB cable to connect your FC to your computer.
- Select the COM port in Betaflight Configurator.
- Click Connect.
💡 If the FC isn’t detected, install the STM32 VCP driver or Zadig driver depending on your board.
3. Flash the Firmware
- Identify Your FC Target
- Check the model name printed on your FC or in the Betaflight documentation.
- Example targets: MATEKF722SE, TMOTORF7HD.
- Backup Settings (if applicable)
- If the FC has previous settings you want to keep, use the CLI command:
- Copy/paste the following command: diff all
- and save the output to a text file.
- If the FC has previous settings you want to keep, use the CLI command:
- Flash
- Go to the Firmware Flasher tab.
- Select the target, version, and enable Full Chip Erase.
- Click Load Firmware (Online) → Flash Firmware.
- Disconnect and reconnect after flashing.
4. Basic Configuration
Ports Tab
- Assign UART ports for your receiver, GPS, or other peripherals.
- Example:
- UART1: Receiver (Serial RX enabled).
- UART3: GPS (set to “GPS” in Peripherals).
Configuration Tab
- Select your ESC protocol (e.g., DShot600 for most modern ESCs).
- Enable OSD for in-goggle flight info.
- Set your motor direction (reverse props or standard).
- Enable features like:
- Airmode – keeps motors spinning at zero throttle for better control.
- Anti-gravity – smooths altitude during throttle changes.
PID Profile
- Beginners can leave default Betaflight PIDs for their quad size (defaults are tuned well for 5-inch drones).
5. Receiver Setup
Receiver Tab
- Select “Serial-based receiver” → “CRSF” for Crossfire/ELRS or “SBUS” for FrSky.
- Move the sticks to check channel mapping.
- If mapping is wrong, change the Channel Map (e.g., AETR1234).
6. Modes & Arming
Modes Tab
- Assign an Arm switch (mandatory).
- Assign a Mode switch for:
- Angle Mode (beginner stability).
- Horizon Mode (flips allowed).
- Acro Mode (full manual).
- Assign a Beeper switch (optional but useful).
7. Calibrate Accelerometer & ESCs
- Accelerometer: Place the drone level and click Calibrate Accelerometer in the Setup tab.
- ESC Calibration: Usually unnecessary for DShot protocols, but required for PWM/Oneshot.
8. Check Motor Direction
- Remove props before testing.
- Go to the Motors Tab, enable motor control, and check each motor spins in the correct direction (as shown in the diagram).
- Reverse motor direction in BLHeli Configurator if needed.
9. OSD Setup
- On-Screen Display Tab: Add voltage, timer, RSSI, and flight mode indicators.
- Arrange them so they’re visible but not blocking your main view.
10. Save & Test Before Flight
- Disconnect from Betaflight.
- Test arming and disarming on the bench (props off).
- Double-check:
- Receiver input works.
- Motors respond correctly.
- Failsafe is set (motors stop when radio is off).
