@phil2015 I don’t know for sure but I would bet on this being Eduard’s own design. Arma hasn’t made any 109:s and it doesn’t feel like an “Arma-subject” either (they don’t seem to be into things Luftwaffe). Apart from that, Eduard should be well set up with CAD data for these aircraft after making them in several other scales.
No matter what, I’m sure we’re in for a treat

I look forward to it!
