So in summary what we are seeing is a "scaled prototype" (ie not full size) weighing 25kg (not something with a 200kg payload or a 300 mile range).
The airfield in Tussenhausen Germany can be viewed on Google Earth.
According to google earth the taxiway the craft lifted from is around 6.5 meters in width.
Video from a few angles indicates the wingspan of the lilium craft is a similar width to the taxiway.
So an extraordinary achievement if the craft has a wingspan of over 6 meters yet weights only 25kg
