Did you get the part about our friend with the problem coming from Italy? What’s your Italian like? My guess is not as good as her English.... if you use a bit of imagination it seems the video feed isn’t very good.I don't think firmware is going to fix the problem.
This Statement is really vague,
"The signal video is not good also when the drone is near my radioconteoller."
What does "signal video is not good" mean?
