How high do u recon ken? was that a shot from the Nex5?
If it had been the MK I could tell you exactly how high from the flight log, with WKM who knows, I guess that capability will come with View and Waypoint. When the AD-6 has been that small visually it was up around 400 meters, the Y6 is a bit bigger than the AD-6...
I was using the Nex 5N, I pulled that shot from the video to see how well that worked. Definitely not as crisp as a still shot but good enough to use as the background on my desktop computer.
