I have used them on my X5S. I would imagine they would work on the X7. You have to plug in the goggles to the USB connection in order for the head tracking to work. Not a problem if you have two controllers.
Would you mind sharing how you managed to get the head tracking with the X7 to work?
We’ve spent days trying all the variations we can think of, we’ve picked the brains of companies here in the uk, we’ve emailed DJI and trawled the internet, all without success.
From all our research you’re the only people who’ve confirmed it works and we’d love your help to get it up and running.
