## Where to Buy

The _Beta75X_ can be bought from a number of vendors, including:

* [GetFPV](https://www.getfpv.com/beta75x-2s-brushless-whoop-micro-quadcopter-xt30-frsky.html)
* [Amazon](https://www.amazon.com/BETAFPV-Beta75X-Brushless-Quadcopter-Smartaudio/dp/B07H86XSPW)

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](https://www.fatshark.com/product-page/dominator-v3).

    :::note 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](../omnibus_f4_sd#bootloader) topic (this is the flight controller board on the _Beta75X_).

:::tip You can always [reinstall Betaflight](../../../../advanced_config/bootloader_update_from_betaflight#reinstall-betaflight) later if you want! :::

## Installation/Configuration

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

:::note 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). :::

To install and configure PX4:

* [Load PX4 Firmware](../../../config/firmware).
* [Set the Airframe](../../../config/airframe) to _BetaFPV Beta75X 2S Brushless Whoop_.
* Continue with [basic configuration](../../../config), including sensor calibration and radio setup.
