I was a little surprised looking at the Boomerang QuickShot description in the DJI MA manual. I didn't think that the radius would be 99' (30m). My understanding has always been that a radius is calculated from the center of a circle outward therefore, at 180 degrees from one edge to the other makes 198' (60m). If that's the case for the Boomerang QuickShot.......... Wow....... you need some room. I wanted to use this QuickShot on some overlooks in TN and NC. I was also under the impression that distance was adjustable.
