My DJI FPV is only a year or so old but I now see the remote controller DJI has available is not the same model as I have. Does anyone know the difference between the newer boxier form as opposed to the kind that has two handles protruding. I have the "two handles" model. I find my FPV controller to be much, much more responsive than my Mavic 3 controller. sad...but that's for another post. I have the second controller. Thoughts?
