I've had a chance to try this for a few flights and it's workable. There is a distinct lag, but that could be due to my Xiaomi more than the app. I need to add some padding to the nose area of my Google cardboard as that really rests hard on my nose. Overall I'm happy that I can have an FPV experience without breaking the bank. My next step might be to get the Quanum DIY v2 and leave this to ride-alongs.

How much is a ”distinct” lag? That sounds scary if it's as much as a second...or worse?
Hard to say, maybe half a second.
