I've seen two adapted skillfully to the mini or se.
One uses the Uneec Skyline headset at $159. This ebay seller tells you what you need to adapt, including a $25 wifi dongle, maybe 2 cables, and a small battery.
I've seen another setup where they used dji goggles and about the same connections.
Am interested to learn about other successes, how well they work, and if anyone has used the Fat Sharks.
