Hi
I am going to buy Vision 2+ V3.0.
What kind of video lag there is on the fpv? It use WIFI, like FC40. Is the lag same in Vision 2+?
What is FPV range in practice?
Dude, sincerely, if I were you, I wouldn't buy a Vision Plus. Unfortunately, I only found out it's not that good after buying it.
This "lag" you are talking about, is not as laggy as the FC40 wifi, but it exists. Let's start the explanation:
The solution that Dji found out to make FPV acessible for everyone is very interesting. Instead of using a "complicated" analog video feed and having to include a screen along with the Phantom, they installed a module that will transform and transmit the video and telemetry via wifi signal, acessible to everyone who has iOS or Android devices.
But that's part of the problem - it's WiFi. Sometimes, there is a significant delay that will make you unable to know exactly what you're recording, for example. Or you're slowly drifing away with the wind.
It's also not very reliable, because sometimes you will lose your video feed for no reason, and wait up to 5s so it can come back.
My solution was to install an additional 1.2GHz analog FPV video feed, so the image that comes is crystal clear, hi-deff and extremely reliable. I really don't know how people can stand using Vision Plus's wifi experience.
My thoughts.
