Please note, that Smart Audio on this VTX does not work in Betaflight 3.3 out of the box, you will need to use butterflight, or wait for Betflight 3.4 to use smart audio with the VTX.  Otherwise this VTX works just like any other and has an LED display to change channel/power levels the old way.

The VTX[T] is not just another FPV video transmitter, it has been built to pack all the latest technology into a small and affordable package. This is aimed to be a viable alternative to the more expensive TBS unify, or immersionRC tramp video transmitters. This VTX supports a wide range of power input (7-24V), will output a constant 5V to your FPV camera, and is able to switch between 25, 200, 500, and 800mW of transmission power.

In addition to serving the function of a basic VTX, the Chaos FPV VTX[T] supports BetaFlight VTX telemetry allowing you to control settings on your VTX directly from your betaflight OSD. All you need to do is hook up the telemetry connection from the VTX to a spare UART port on your flight controller.

Pitmode functionality is supported which means that if you are flying at a race event, the VTX will power on with a low transmit power, allowing you to test and configure your drone without causing interference to other FPV pilots. Then before you go and race you press the button to enable the VTX to transmit at full power for your race. Of course, if you are flying alone you can disable pit mode entirely.

    Solid Performer - Way above the bar!

    This VTX performs brilliantly, I've had no faults with it. For the price especially, it's punching way above where you might expect it to - honestly I feel it's one of the best out there at the moment for FPV freestyle.

    I don't know why you would buy anything else. Great range of frequencies and a great range in the field.

    Good cheap vtx. Although mine arrived with a faulty display. But seems to work on all power settings
