That transceiver on the plane looks pretty beastly (big/heavy) but if it delivers
on the 80mS max latency claim, then I'm interested. As with any digital video link,
what I want to see is how well it degrades and recovers when the signal
is weak/blocked/etc..

It's meant to replace your vtx, rc rx, osd, hdmi adapter and it has a fan and sma connectors
I think that's pretty good

Ya, I know what it replaces. That's why I said transceiver.
It must be pictured massively out of scale relative to the ground unit
if it's only 70g (2.5oz).

So the Chinese finally figured out how to ripoff/reverse engineer Amimon's wireless video MIMO technology?

Do a video of a digital stopwatch. The watch itself and the monitor beside it. That will lets us know if we will want it for fpv.

I'm not sure it is intended for FPV video.. it is intended for multicopter operators, for which the latency does not matter as much as the details.
