I park my car with ease, thanks to the back up camera's projection guide. So it got me thinking... why can't DJI implement something similar. You are probably thinking, but the camera mode comes with grid lines. True... but it's not predictive of the size of the phantom. Imagine actually seeing the width of your phantom projected into a gap/space before flying through it. I refuse to cage my bird with prop guards, so I've had my horrific moments. This tech will definitely save a couple wings. I wonder if this is something they can incorporate into the Dji Go app. What do you think?
