I get asked a lot how I mount my FPV monitors to my radios. My favorite mount for the Phantom radio is the 3D-printed Rave Aerial Video mount, which snaps into place using the radio’s antenna and rear metal handle. It locks in solidly, and is perfect for the Black Pearl 5.8Ghz Diversity Receiver / Monitor, which is my standard receiver / monitor when I’m flying around using my Boscam TS-353 FPV video transmitter.
When I was at Burning Man last week, I used a Lightbridge setup on my Phantom 2, and elected to use a Lilliput 7” 664/o/p monitor, instead. Rave Aerial Video says they have a version that works with the Lilliput 668, but I’m not sure if it works with the 664 (but I don’t have it). I used the Tarot video mount, instead, and it was absolutely terrible. After a day or two, everything was loose, and I had to literally tape the monitor to my radio, which wasn’t ideal.
I think I’m going to go with Sam Chen's mounting approach for Lilliput and heavier displays. Sam opened up his radio, drilled a hole, and mounted a mini ball head with a quick-release plate (use a large washer on the inner side so the ball head is secured by a lot of plastic).
For quick release, I’ll likely use a Mini Clamp DAC-25, which is a tiny, inexpensive, and Arca-Swiss compatible (I use RSS for everything), and a SUNWAYFOTO 26mm QR Plate, which has 3 holes for maximum positioning versatility. If you aren’t standardized around Arca-Swiss or RRS, any ol’ cheap quick-release product is probably fine.
If you’re wondering what timer Sam has mounted to his radio in the photo above, it’s the Presto 04213.
Finally, with all that weight on top of your radio, you will likely want to shift your neck strap mounting location further up. I use these cheap balancers from eBay. Even attaching your strap to the third hole won’t be enough to fully balance your radio, but it will help.
