Caddx Walksnail Goggles X solution for Wildfire/Speedybee modules

AV-Input on the Goggles X has some issues with certain Analog receiver modules - Foxeer Wildfire, Speedybee VRX and the URUAV RX5808 Evo. A comment on my previous video (by @joeljones603) suggested I try an AV to HDMI adapter to see if it works - and I was pleasantly surprised it works very well.... With a catch. But overall I am happy wiThis video details what you need to build your own.

Parts used:
