Betaflight Setup Guide

Betaflight is the most popular firmware for FPV drones. This guide covers the essential configuration steps.

Connecting to Betaflight Configurator

1. Download Betaflight Configurator from the Chrome Web Store or GitHub releases
2. Connect your FC via USB
3. Select the correct COM port and click Connect

Essential Configuration

Ports Tab

• Enable Serial RX on the UART connected to your receiver
• Enable MSP on USB (default)

Configuration Tab

• Set Motor Protocol to DSHOT600 (recommended for most builds)
• Enable Bidirectional DSHOT for RPM filtering
• Set Gyro Update and PID Loop to 8kHz/8kHz (F7/H7) or 8kHz/4kHz (F4)

Receiver Tab

• Select your receiver protocol (CRSF for ELRS/Crossfire, SBUS for FrSky)
• Verify channel mapping matches your radio

Modes Tab

• Assign ARM to a switch (required)
• Assign ANGLE mode for beginners
• Assign BEEPER for finding crashed quads
• Optional: TURTLE MODE (flip after crash)

PID Tuning Basics

The default PIDs work well for most 5" builds. Only tune if you notice: - Oscillations → reduce P - Slow response → increase P - Bounce-back after flips → increase D - Drift during hover → adjust I

OSD Setup

Configure the OSD to show: - Battery voltage (critical for LiPo health) - Flight time - RSSI (signal strength) - Warnings (low battery, failsafe)
