A Swiss-German undertaking. (Page in German but has pictures even if you don’t understand the language that makes it pretty clear.)
Small companies providing different expertise to the project. Liquid engines from SPL, Switzerland, airframe from Extreme Aircraft, a German Extra-like aerobatic plane maker. Prototype looks like an acrobatic plane with a rocket in the aft.
I’ll update more later.
