Introduction about Betaflight Configuration

Many enthusiasts face challenges with Betaflight, especially when the FPV (First Person View) doesn’t display after binding. This guide aims to demystify the setup process for your VTX (Video Transmitter) and radio controller channels, ensuring a seamless connection.

Step-by-Step Configuration for VTX and radio controller channels

Step 1: Identifying the Receiver Port

Begin by determining which port on the flight controller your receiver is soldered to.

Step 2: Betaflight Connection

  • Connect your FPV drone to Betaflight using a data cable.
  • Navigate to the “Ports” tab in the top left corner
  • Enable the corresponding port for your receiver and click “Save”. The flight controller will restart automatically.

Step 3: Receiver Setup

In the “Receiver” tab, select the communication protocol your receiver uses.

  • Choose “Serial (via UART)” for most receivers.
  • For TBS Crossfire or ELRS, select “CRSF” as the Serial Receiver Provider.
  • Ensure your radio controller sticks are showing feedback on this interface. If not:
  • Verify your receiver is powered on and connections (TX and RX) are correct.
  • If issues persist, try a different port and recheck the controller channels under the “Receiver” tab.

Step 4: Mode Configuration

ARM Mode:

  • Essential for enabling motor output and flight.
  • Disarm immediately after landing or crashing to stop motors.
  • In the “Modes” tab, click “Add Range”, select an auto channel, and move the desired switch.
  • Adjust the yellow tick mark to cover the desired position and click “Save”.

Angle and Horizon Modes:

  • Set up using a three-position switch: ANGLE, HORIZON, and ACRO (for experienced users).
  • Beginners should start with ANGLE mode, then progress to HORIZON and finally ACRO mode.

Beeper Mode

Activates the drone’s beeper, invaluable for locating your FPV drone after a crash.

Additional Modes for Beginners

Consider setting up the “FLIP OVER AFTER CRASH” (Turtle Mode) to aid in recovery after crashes.

Conclusion

With your control system now configured, your FPV drone is ready for its initial flight. In our next episode, we’ll delve into the power system settings, further enhancing your drone flying experience. Stay tuned for more insights and happy flying!
