Beautiful! I've never seen the Ar Projekt 1 before. She's gorgeous (although I wonder how they planned to get around FOD!).
You are right...the engine intakes are behind the nose wheel and therefore likely to injest hurtful stuff.
It seems there are quite a few German projects designs that followed suit, which is a good reason they didn't receive further development.
And I, not being any aircraft engineer or of any kind for that matter, simply draw them up as per the schematics.
But a beauty nonetheless.
In fact I'm working on the single seat all-weather fighter version as we speak...or type.
Will post when ready.
Many thanks
