For my Betaflight 4.6 (or 2025.12.1) trainings, I’ve written a complete script. In it, I cover everything you need to know to flash your copter with Betaflight and configure it from scratch.

I’m providing this script in a slightly shortened version for anyone interested!

In the script, you’ll find, among other things:

• Explanations about batteries
• How to flash the firmware
• Explanations of the individual tabs in the Betaflight Configurator
• GPS RTH (Return to Home) configuration
• Compass module calibration
• Setting up Altitude Hold and Position Hold
• Filter tuning
• PID tuning
