yep… cheap 15$… I also would like if we get a “two - model - design” : basic-model and full-model ( similar to e.g. DCS ) . I assume lots of users would spend for a real full modelled aircraft ( and of course with a usefull manual included ) much more than 15$.
languages can be real fun 
… it is in english often called “german B” , but as you mentioned the “ß”
have nothing to do with a “B” or “b” or “Beta”…
Also the Junkers is just a old lady, today we would ( have to ) write it as Pressluft or Druckluft, to make it more clear
