The short answer is NO. But if you are flying locally and do not have your maps current then yes. There are other times I find the cellular connection handy, i.e., I prep the night before and I’m good to go. I get to my flight point and DJI says “I wanna update!” Guess what ya need! I live less than 1 mile from the center of KCOS. I need cellular to grant permission to fly in immediate Class C air space, (even at the house at 30 feet) without which the props will not even spin. If I move to a different park ( 1.5 mile from center) I am good to go (after contacting both KCOS Ops and FAA tower), and I’m still within the 5 mile radius. My guess is that about 1/4 of Colo Spgs falls in the KCOS class C air space. The north end gets tagged by the USAF Academy (not sure, but I believe it is D.
I mentioned I use LITCHI on my Tab. This is because I can program Way Points for smoother video and variable speed. I maintain my remote at all times but remain hands off for the whole flight from lift off to completion at landing. See my video (yeah, I bragging).
My Note 8 keeps the DJI GO4 app. Things I learned from making this video were 1 you do not have to fly your drone forwards only, 2 you do not need to have your thumb/index on the sticks all the time, and 3 you learn new perspectives by flying the exact same flight path 5 different times. I kept the same way points but changed altitude and or speed on each of 5 flights. ( I have 5 batteries for the
MA, only to allow me to change up to differing perspectives on essentially the same flight. Altitude, speed, lenses. Then back home on my old Dell laptop for editing on Wondershare’s Filmora. I am attempting to do very much the same technique on freehand flying but still find turns and transitions are just a little too jerky for my own satisfaction.
