Kay H I think this aircraft is more user-friendly than the x520. I have both and like my x450 much better. it allows you to fly in spots where there are obstacles. x450 much more maneuverable in hover mode especially if there is any wind.

Kay H I believe the plug he is referring to is audio. The goggles do not transmit a signal. They only receive. all you would need is a small fpv monitor/ receiver. as long as your aircraft and fpv viewing device are on the same channel there should be no trouble. Your aircraft camera is constantly streaming data. The newer smartphones have the ability for fpv data. As long as it has a Wi-Fi band that have the letters ac after it.

Kay H Most 5G Wi-Fi connections for FPV require your phone to have Wi-Fi-802.11ac.. make sure your phone handles this frequency protocol. Majority of newer phones do but there are still some out there that don't. Make sure it ends in ac.

Kay H No ....Flying weight is the weight of the Drone with the battery and everything else attached to it. It has nothing to do with Lift. Certain countries require you to get a license if your drone weighs over a certain amount. This drone does not Require a license in the USA.
