I have a Runcam Split V2 on one of my wings, never worried too much about the latency with these dual FPV/HD camera units but this clip bought it home.
Listen to the throttle drop and rise after a second or so,
Then see the throttle value on the OSD,
It shows how the audio comes back to the pilot a few seconds quicker than the video does 
.
Need to rethink my camera setup on my wings, my reactions are slow enough when ‘sport flying’ without this handicap
