How to setup your FPV quad for the first time

All of my quads are sold with a DJI video transmitter (TX), a Crossfire receiver (RX) and a either a Tango 2 Pro or a Radiomaster with Crossfire module. The following description focuses on the setup with a Tango 2:

  • Charge the batteries of your Tango 2 and one battery of your quad.
  • Power up your Tango 2 and long press the menu button. Choose "TBS Agent Lite", then choose "Tango II XF", and then click "Bind".
  • Plug the battery into your quad. Press the tiny bind button on your RX. Sometimes, there is a sticker where to find it. If there is no label, find the button on the picture below. The led of the RX will light up red, so this should be easy to find.

  • The RX should now bind to your Tango 2. Be patient and wait a moment until you get the update notification prompt described in the next step.
  • On your Tango 2, you may now need to prompt to update the RX. If so, click enter by pushing down the scroll wheel. 
  • This step and the next step are only required, if the binding did not work: If your Tango 2 blinks blue and you get the message "Update XF in Agent M" you may need to update the firmware of your Tango 2 or more likely re-install the current version of the firmware on your Tango 2 (as of the time of writing this, its v6.13).Install firmware 6.13
  • This step and the previous step are only required, if the binding did not work: Go to the TBS website for the Tango 2 and click on Agent M under "More Information". Follow the instructions.
  • Once the RX is bound to your TX, bind the DJI FPV Goggles v2 to your DJI Video transmitter (VTX) like the DJI Vista, DJI Air Unit or similar. Power up your Goggles and go to "Settings", "About" and click the last item on the list "Switch to DJI Digital FPV System". Watch part of the video below if you struggle with this step.

  • Now with the Goggles in FPV mode, power up your Tango 2, your quad and your DJI Goggles. Find the bind button on your Goggles and quad with the help of the picture below. On the VTX, there is an green LED very close to the bind button so finding should be easy as well.DJI Vista locate bind button on VTX and DJI Goggles
  • Press the bind button on your DJI Goggles twice until it beeps. Then, press the bind button on the DJI Video TX on your quad until the LED is solid red. If you have issues binding your Goggles to your Video TX, watch this video. There is also a little power hack in it to boost the output power of your VTX but check your local laws if this is permissible.

  • If you do not have a video feed after binding your Googles and the VTX, your DJI Video TX on your quad will now need to be activated with DJI Assistant 2 FPV series. Download and install the software. Then power up your Tango 2, Goggles and quad and connect it to your computer via USB. Start the activation. Afterwards, check if your DJI Air Unit is up-to-date, otherwise update the firmware.
  • You are now able to access the quad from your Goggles. Activate the OSD and change all the settings as you wish. Check what buttons are for what. Check how to arm your quad (with the SA button = big button on the top left) and what button to use for angle mode.
  • You should now also download and install the latest version of the Betaflight Configurator.
  • Your quad may not arm at this point due to the wrong mapping of the channels. When you connect your quad to Betaflight, the throttle is in the roll position and pitch is in yaw. Watch the video below to map your channels correctly BUT use "TREA1234" instead (if you fly Mode 2) of what the guy in the video says:

  • Now your quad still does not arm? Watch this:

  • As a last step, I always check Joshua Bardwell's Youtube videos on the respective model, if available, to see what settings he recommends to change in Betaflight. I am a patreon of his as he has one of the best Youtube channels for FPV there is so big shout out to JB. Here is one as an example for the iFlight Nazgul Evoque F5:

  • There's a lot more to it, but for now, you are done and ready for your first flight.
  • If you want to know more about the setup or your quad is still not flying, check out this more comprehensive video from JB for a Betaflight setup for beginners:
