So many times I have been restricted to sitting in front, at a fixed location , looking into a FPV screen to do my flying , especially take off and landings.
Also there are times when the model has unknowingly flown behind a obstical and signal and video is lost.
So why not have the FPV screen attached to you and easily have line of sight available to you within a second or two.
Also in some flying sites it is not practical to set up a FPV ground station easily.
The best attribute is having line of sight and the fpv screen available in the blink of an eye and it being portable.
Unlike fpv goggles, you have the best of both views of your model without taking off goggles and trying to find where your model id in the sky.
