The following guide will enable you to utilize your Team Black Sheep (TBS) SmartAudio enabled Video Transmitter (VTX) with RaceFlightOne (RF1).

 

Firstly, you will need to connect the VTX to your Revolt Flight Controller (This guide will work for both V1 and V2 Revolt flight controllers).

Connect the VTX to a power source, if you have a TBS Unify HV – Race or TBS Unify Pro HV, these can be connected to either a 12v source with a supply current of 600mA or more, or direct to Lipo Power up to 6s. A TBS Unify Pro V2 will need a 5v power source with a supply current of 600mA.

 

Next you will connect the VTX to the Revolt, refer to the below diagram.

 

 

The aforementioned is detailed in the video below-

 

Once you are happy with the connection to the power source and Revolt, you are ready to set it up.

 

Open the RF1 GUI, if this is your first time setting up the Revolt you will be prompted as per below –

Click “CONTINUE” –

 

Choose your receiver and click “NEXT” –

Choose your VTX, in this guide we will be selecting TBS Unify Pro 5G8 V2, use this option for Unify HV- Race and Unify HV as well. Then click “NEXT” –

Once you have continued through the rest of your setup, you then go to the Configuration Tab. If you had already setup your Revolt before adding the TBS Smart Audio VTX, this is where you start from.

 

Once in the configuration Tab, Choose USART 3 TX, (Only choose USART 3 RX, if you have connected the Smart Audio Wire to the RX3 pin on your Revolt).

Click “SAVE” in the bottom right corner of the GUI.

 

Then we want to setup how the VTX is initiated on startup. Click “VTX PITMODE TYPE”.

Follow the instructions, make sure you have your battery connected and have removed your props. Check the box to confirm and click “NEXT”.

 

You will then have a drop-down box options to choose what you want your VTX to do on start up. The default option is “Vtx On After Power Cycle”, what this means is as soon as your plug your battery in to your quad, the VTX will be broadcasting.

If you choose “Vtx PitMode After Power Cycle”, this means when you plug your battery in your VTX will be in Pit Mode on start up. You will then be able to activate your VTX via a switch.

 

 

Once you have chosen your option, click “NEXT” if all has gone well you will be prompted with the following screen.

If you are seeing the below screen, there has been an error setting the VTX PitMode Type, this error shows up if your revolt is not detecting the VTX. Some causes of this are, Battery is not connected, Smart Audio wired to the wrong Pin, Wrong USART selected.

 

Once you have completed the setup, if you have chosen “Vtx PitMode After Power Cycle” you can then setup a switch to active the VTX, click on the “SETUP” tab and scroll down to find “VTXON channel” choose the channel you wish to use to activate your VTX and set the values using the sliders.

 

 

Using Smart Audio with Spektrum.

Once you have setup Smart Audio on your Revolt you can now use your compatible Spektrum Radio to change the VTX settings.

Make sure your battery is plugged in to your quad when changing the settings. Settings can be changed while the VTX is in PitMode and whilst On.

To access the VTX settings on your Spektrum radio, press down on the scroll wheel to enter the “Function List” menu. Use the scroll wheel to scroll through the options until you find “VTX Setup”, if you can not find this option in the menu, make sure you are using a compatible radio and you have updated to the latest firmware.

Press down on the scroll wheel to enter the “VTX Setup” option.  You will then be prompted with VTX values that can be changed – Channel, Band, Power and Mode. Modify the settings to your desired values. Then select “SEND” and press down on the scroll wheel.

Spektrum VTX control does not require a telemetry receiver to work. The Spektrum VTX menu is limited to legal 5.8 bands thus some channels will not be available in the Spektrum VTX channel menu.

Using Smart Audio with Taranis.

Taranis VTX Control requires a telemetry receiver connected to smartport, the RF.LUA installed and “Taranis telemetry” option activated in configuration tab to work, before proceeding to use Smart Audio with a Taranis, please follow the Guide on how to install the RF.LUA if you haven’t done so already. The RF.LUA installation guide can be found here – http://raceflightinfo.com/?p=2696 and the Taranis Telemetry Receiver  guide can be found here – <Coming Soon>

To access the VTX settings on your Taranis radio hold the PAGE button down enter the “RaceFlight One Menu”. Push both sticks on your radio toward the bottom center (down and inward towards the center of the radio) position and hold it for around 3 seconds. The first page that appears is the VTX settings – Band, Channel, Power. A“>” symbol is the cursor indicating which option you are at. You can move the cursor up and down with the pitch stick. You can select an option to change its value by pushing stick to the right (roll right). To change value you can move the stick up and down (pitch). Once you have finished changing your desired settings, push the stick to the left (roll left) to exit the option.

Once you have finished modifying your desired VTX settings, select “Set and Exit” to save your changes.

 

Using Smart Audio via Console.

If you require console to change the channels through the phone app or the GUI, here are the list of commands –

vtxinfo (Displays the current VTX settings)

vtxon (Turns VTX on)

vtxpit (Turns VTX PitMode on, power cycle required)

vtxpower (Changes power output, example would be “vtxpower 1” would select a 200mw output from your unify).
0 = 25mw
1 = 200mw
2 = 500mw
3 = 800mw (Not supported on race version)

vtxbandchannel (Changes band and channel output, example would be, if I wanted my channel to be 5760, the command would be “vtxvtxbandchannel f2”)

Band CH 1 CH 2 CH 3 CH 4 CH 5 CH 6 CH 7 CH 8
A 5865 5845 5825 5805 5785 5765 5745 5725
B 5733 5752 5771 5790 5809 5828 5847 5866
E 5705 5685 5665 5645 5885 5905 5925 5945
F 5740 5760 5780 5800 5820 5840 5860 5880

*At the time of writing this, if you are using Spektrum to control your Smart Audio, the console will not retain your changes, this will soon be fixed.

Using smart Audio via OSD.

Coming Soon.

  1. I see you plug the audio from the unify to the revolt but if you do so does that mean you cannot have audio from your camera like the swift 2 has a built-in microphone.
