Many people have said in various places that the lag of videolink in Q500 4k is so huge that it ruins the whole purpose of having videolink. Some have said that the delay can get up to 2 seconds. I've heard that in the Q500 manual it even says not to fly FPV due to the lag. I cant imagine people being satisfied to a laggy videolink, but I've seen satisfied Q500 owners on the internet nevertheless. Somebody said that the lag varies with the 4k model depending on what your shooting. Meaning that shooting in 4k instead of FullHD increases the lag etc. Can anyone confirm this? -I'm planning to buy the Q500 G for GoPro. Could someone tell me if the lag is the same as in 4k model or is there a difference as the setup is bit different. In 4k model the transmitter is built-into the camera in G model the transmitter is external and takes in the videofeed from the GoPro's output. Thanks!
