How to get your wireless head tracking going with the Focal V2.

One of the cool features of the Focal V2 FPV goggles is the wireless head tracking feature. Less wires equals more fun in my book. I have a pan and tilt FPV plane on the work bench and I wanted to get the Focal goggles working with it. I did find the procedure a little tricky so after I got everything working I shot a video explaining the process.

In this article I'm going to include full instructions on how to get the wireless head tracking setup, as well as a video showing the procedure. I hope this makes things easier for any users out there that are trying to get this going on their FPV rigs.

Wireless Head Tracking

The Trainer FPV function found in Spektrum AirWare radios with wireless trainer, enables you to control FPV head-tracking in either wireless or wired mode. I used the DX6e with my application.

The default channel assignments are:

  • CH17 Frequency
  • CH18 Pan
  • CH19 Tilt

TIP: All wireless buddy box equipped Spektrum transmitters can function with up to 20 channel input for this functionality in the FPV trainer mode.

You may assign incoming head-tracker channels to any available output channel in the transmitter.

Instructions:

  1. Select Wireless Trainer from the Trainer menu.
  2. Change the trainer mode from Inhibit to FPV.
  3. Select the switch you wish to use for the head tracker, then select NEXT.
  4. Select the Output Channel where the head tracker servo is connected.
  5. Change Mode: Master to Mode: Slave.
  6. Select Input Channel.
  7. Select bind and press the scroll wheel to put the Transmitter into bind mode.
  8. Power on the headset and it will attempt to bind to the wireless buddy box function in the transmitter. The Transmitter should report DSMX 11ms after a successful bind.
  9. Test the head tracker movement.Move the head tracker switch to the On position, then move your head. The camera should move accordingly.
  10. Adjust the Scale value to change the amount of camera movement. If the camera moves in the wrong direction, change the Direction option from Normal to Reverse.

Video Walk Through

Conclusion

Hopefully this will walk you through the steps of getting your Focal V2 goggles talking wirelessly to your pan-and-tilt camera. I think this feature really makes the V2 Fatshark unit from Spektrum pretty handy.

I love the wireless head tracking. I did something similar a few months back with my old Attitudes.

I have since gotten a Focal V2 and am more interested in the wireless frequency setting. Unless I missed something the video below didn't really explain anything.

Thanks!

the frequency control system is something that hasn't been widely implemented, but its available in the SPMVA2500 and SPMVA2510. with those cameras, you can just plug into the frequency control channel from the wireless control (ch 17 input) and assign it to an output channel of your choice where you plug the camera in. Band control wasn't part of it, so the headset and camera have to be manually set to the same band, but once on the same band you can control tx frequency by changing the headset channel. Use the headset first to find an open channel, and then power up and it will go right to that channel.

I wish this would catch on! especially in the BNF's like the inductrix.

Thank you for the info.

I have the HD3s with a Trinity HT module and a set of DX9s with the Wireless HT Trainer function. Do I have to have something else to make this work? I really hate the HT cable.

You'll have to do what I did above with the wireless head tracking for my old attitudes. You're goggles will need a spektrum Tx for the wireless trainer to work on your transmitter.

Help on Headtracking (Focal V2 )


My friend I Cannot make it work on mine. I have the same google the Focal V2 FPV Wireless Headset with Diversity (SPMVR2510)

I am using Elite Radian XL BNF. I have channel 4 and 5 free. But i cannot seem to Bind my Focal V2 . Any help please?

I have set the FPV on Channel 4 (rudder) and Channel 5 ( Gear ), followed the instructions but when i press the "Bind" nothing happens... ANY ADVICE PLEASE LET ME KNOW

Please note that I am using a VTX Cricket 600. from this I connect my camera. ( What i am trying to say is that the camera does not connect to the spectrum receiver, it goes direct to the VTX cricket ).- Hence the servo leads of my camera pan/tilt go direct to the stock receiver from spectrum ( AR636A )
Any suggestions?

Hello, I know it inside and out, let me try to help! The Focal headset (V2 and DVR) binds to the wireless buddy box on a Spektrum Radio system (wireless buddy box capable radio required). you cannot bind it directly to the model. your camera should be connected directly to your video transmitter, but the servos you want to use for pan and tilt need to the RC controller. The Focal sends the head tracking signals for Pan on ch 18 and tilt on 20. In the FPV wireless trainer menu, you can change the output for those to whatever you need. You can use channles 5 and 6 on a 636 for this in some situations, depending if it came with a BNF with SAFE or if its out of the Spektrum box. Different configurations complicate this. If its a 636 from a BNF, you might not have access to those extra channels because you are already using them for flight modes (or other things, depending on the model).

what transmitter (controller, not video) are you trying to use?

In a simple sense this is how it works
Headset ---> wireless buddy box channels 17-20 ---> Spektrum wireless FPV menu, change outputs to meet your rx/model setup, lets just say pan on 5 and tilt on 6---> plug servos into channels 5 and 6

Bind the headset to the radio in the FPV trainer menu, and go from there with the rest of the setup.
The functions are largely the same as the new Focal DVR, you might take a look at that manual, a lot of new info was added in there.
