GPS mount for DJI Phantom 3?

Nice… But I was of the belief the ground plane had to be around 10cm diameter. I guess it would block the airflow for the quad though. I wonder if anyone has experimented with a mesh of some kind. Or if it was mounted somewhat higher.

How is that mounted? I think I can see the reach ziptied to the hind legs, is the entire unit simply ziptied to the legs? Looks neat in any case, thanks for sharing.
