You have an amazing production rate, it blows me away.
It varies, the 404 took me three days as it's poorly documented and a very unusual/complex shape that took me several goes to model satisfactorily whilst the Stopa-Caproni is quite simple and I had some clear plans and photos to work from so it only took me a few hours.
So have you created any purely of your own design?
Not yet, I may not as the 1930s was an amazingly inventive era for aircraft designs and there's a huge backlog of real-ish world designs to work through, some of them far more outlandish than anything I could imagine (EG the 404).
