With the release of ground station features in the Vision app the need for a mobile connection came..
Went back to my trusty iPad mini with 4G.
Then i needed a new mount on the receiver for the iPad mini.
Found a really neat one which is partially 3d printed.

This holder is also nicely balanced in the middle instead of the default smartphone holder..
