### Telemetry radio (optional)

A telemetry radio is an optional component that can be used to wirelessly connect a ground control station (GCS) computer with the autopilot. This allows you to view in-flight data, change missions on the fly, and tune in the vehicle during flight.

PX4/Pixhawk Mini support many different telemetry radios. The radio used in this build is the (highly recommended) _3DR Telemetry Radio (915MHz)_ (Discontinued).

:::note Telemetry radios use different frequency bands in order to comply with local regulations. Select a version appropriate for your region: USA - 915 MHz, Europe/Australia - 433MHz :::

The telemetry kit includes:

* Two telemetry transceivers (for vehicle and GCS)
* Micro USB cable
* Android OTG adapter cable
* Double-sided tape

![3DR Telemetry Radio Kit - unboxed](https://4155462212-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-LArEa7z2SPawfl3HpCD%2Fuploads%2Fgit-blob-6d99e9a897cdd86ed3c8c656a191466f08e064e3%2F3dr_telemetry_radio_kit.jpg?alt=media)

## Off-frame assembly

This section shows how the electronics are wired (off frame) and how the frame is assembled without the electronics. This information can be used for reference if the on-the-frame screenshots are not sufficiently clear.

### Electronics Wiring/Connections (off frame)

The image below shows the _standard_ multicopter wiring for _Pixhawk Mini_. It uses the _Quad Power Distribution Board_ to power the ESCs, Pixhawk and Pixhawk power rail (the board includes an integrated power module that supports batteries up to 4S).

:::note For this QAV250 build we instead use the separate 10S Power module to power the ESCs and Pixhawk, and we don't use the optional external switch. The wiring is otherwise similar! :::

## PX4 Configuration

_QGroundControl_ is used to install the PX4 autopilot and configure/tune it for the frame. [Download and install](http://qgroundcontrol.com/downloads/) _QGroundControl_ for your platform.

:::tip Full instructions for installing and configuring PX4 can be found in [Basic Configuration](../../config). :::

:::warning Always make sure to have either battery or propellers physically removed from your vehicle during any initial configuration. Better safe than sorry! :::

First update the firmware, airframe, and actuator mappings:

* [Firmware](../../config/firmware)
*   [Airframe](../../config/airframe)

    You will need to select the _Generic 250 Racer_ airframe (**Quadrotor x > Generic 250 Racer**).

    ![QGC airframe selection of generic 250 racer](https://4155462212-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-LArEa7z2SPawfl3HpCD%2Fuploads%2Fgit-blob-aeaeedad3b5b2472c10bb863c4a7ed780b14475f%2Fqgc_airframe_generic_250_racer.png?alt=media)
* [Actuators](../../config/actuators)
  * You should not need to update the vehicle geometry (as this is a preconfigured airframe).
  * Assign actuator functions to outputs to match your wiring.
  * Test the configuration using the sliders.

Then perform the mandatory setup/calibration:

* [Sensor Orientation](../../config/flight_controller_orientation)
* [Compass](../../config/compass)
* [Accelerometer](../../config/accelerometer)
* [Level Horizon Calibration](../../config/level_horizon_calibration)
* [Radio Setup](../../config/radio)
* [Flight Modes](../../config/flight_mode)

Ideally you should also do:

* [ESC Calibration](../../config/esc_calibration)
* [Battery](../../config/battery)
  * 4S (4 cell LiPo) with charged cell voltage 4.05V and empty cell voltage 3.4V (or appropriate values for your battery).
* [Safety](../../config/safety)

### Tuning

Airframe selection sets _default_ autopilot parameters for the frame. These are good enough to fly with, but it is a good idea to tune the parameters for a specific frame build.

For instructions on how, start from [Autotune](../../config/autotune).
