Where to Buy

The Beta75X can be bought from a number of vendors, including:

In addition you will need:

  • An RC transmitter. Beta75X can ship with a number of receivers. PX4 is compatible with all of them, but make sure to select the version that matches your transmitter.

  • LiPo battery charger (vehicle ships with one battery, but you may want spares).

  • FPV goggles if you want to fly FPV. There are many compatible options, including these ones from Fatshark.


    FPV support is completely independent of PX4/flight controller.

Flashing PX4 Bootloader

The Beta75X comes preinstalled with Betaflight.

Before loading PX4 firmware you must first install the PX4 bootloader. Instructions for installing the bootloader can be found in the Omnibus F4 topic (this is the flight controller board on the Beta75X).


You can always reinstall Betaflight later if you want!


Once the bootloader is installed, you should be able to connect the vehicle to QGroundControl via a USB cable.


At time of writing Omnibus F4 is supported on the QGroundControl Daily Build, and prebuilt firmware is provided for the master branch only (stable releases are not yet available).
