Good luck Johannes,
And much sympathy and good will to you and everyone there living and working through the political & social challenges. We certainly have ours too here in the USA.
My son & I have Ulf 1 plans, but we built a Legend Cub instead. We also build larger Member 60 remote controle airplanes with 100cc motors. 
The elevator is so important, you will want the peace of mind and pride of building it yourself.
Happy First week of Advent.

Only spruce has a secific weight of under 550Kg/m³, and for the spars I`ll use Douglas fir. I calclated a weight punishment there of only 2kg when comparing it to spruce.

Considdering the value of an ULF 1 no one would do such a thing.

Because it is a foot launchable ultralight vehicle, it can be handled as what is unofficially called a slope glider, the same holds true for a para glider, and those ultralight vehicles don`t fall under the urisdiction of the aviation admin, but are governed by the Austrian Aeroclub. So actually one has the choice to either get an airworhiness certificate and build an airoplane, or build a slope glider, which in turn may not be flowen outside Austrias airspace. Considering that a homebuilt needs a permit to fly in other countries anyway, this isn`t really any restriction.
