# Software (PX4 / QGC)

By default, **QgroundControl** under **PX4** firmware automatically recognizes telemetry modules as they have already been factory configured by Drotek.

If you do not like our configuration, you can configure your telemetry modules as you like using [this utility](http://vps.oborne.me/3drradioconfig.zip).

Simply connect the module to the PC via the USB cable and open the configuration software.

You can change the values to increase your reach or communicate faster.

**Net ID**: This is the channel that will provide radio, 2 must have the same value.

**Tx Power**: The power tenfold by radio for data transmission. Can be increased to increase the range.

**Air Speed**: cruising speed data through the air. Can be reduced to increase the range.

**Baud**: Communication speed of telemetry. Can be decreased to increase the range.
