I've lost my head and hung under my phantom. The practical thing is that this bracket the same head connector has such a Gopro camera. This allows the mobile terminals in the holder, in turn mounted on the Quadrocopter and you can shoot. The phone hangs very firmly in the holder, so that I fear for the phone had at no time.
The pity is that the mobile phone (on the angle forth) not forward or can not properly position straight through the width of the mobile phone holder. So the mobile phone films always something down. Disturbing it is only when the pilot makes over-the-ground shots. As soon as one is flying high, the phone picks up ordinary images or videos.
For a first solution, without directly going to buy a 300 euro expensive camera, this support is optimal.
