Meine Heimat: Liechtenstein

Over the summer of 2015 we’ve acquired a DJI Phantom 3 Professional and took to the skies of Liechtenstein. A truly stunning scenic country to fly the Drone. This is not a sponsored post, merely our experiences flying drones at altitudes.

 

This post will cover the following chapters: Flying drones in the alps, Exposing the Phantom 3 Professional, Predict weather before flights, Drone Transportation, Troubleshooting.

Flying in the alps is defiantly an experience, we are used to 0m altitude and sandy deserts, windy mount peaks were a first. I would estimate the winds would have been around 10-15km/h at the peaks (recommended max-wind speed for flight 19Knots or 40km/h) so we had the green light to take flight.

In the valley of Malbun, a small town in Liechtenstein, we set flight to battle test the drone for any future projects. We decided to cover the rest of Liechtenstein but cover it in two parts, the north and south.

 

Exposing the Phantom 3 Professional

Keeping in mind the camera’s sensor is a Sony EXMOR 1/2.3” sensor with 12.7MP, It isn’t a low-light king like other sensors Sony makes, but it is usable. The sensor can boost its ISO up to 3200, the noise floor is not too bad. The 4k resolution it provides is great, especially if you are downscaling your video to a 1080p timeline, the added sharpness and clarity is pronounced, it also allows you do post stabilisation without warping your image, but the gimbal is already pretty good.
