We took this aerial footage in Vienna in 2015 using a modded Phantom DJI II and a GoPro3 Sillver in Vienna's Augarten park.

Flying drones is fun!

Unfortunately we never did get to use it "for work" because a few months later the Austrian drone laws were made far stricter so a DJI II was no longer viable for commercial work. Alas!

Range and signal strength were enhanced along with a custom controller/scheme.
