Now there is a living example of A5, HTC can rectify now the stall characteristics and turn radius data of our carton plane.
Doesn't work that way... It's rebuilt. Does it have pilot armor? Guns? Ammo? Armor on the ammo bays? Armor on the oil ring? What engine does it have? Is it even remotely similar to the original?
Even IF it could be ballasted somehow to represent the real aircraft weights, and IF that ballast was all in the correct spots so as to simulate historical center of gravity, it would never be run at war emergency power for flight testing when (assuming it has the real engine restored) there are few spare parts and the thing is so rare it must stay safe for the rest of its life.
It will fly, for sure... But I doubt it'll ever reach historic war-time performance numbers because it will either be underpowered, overpowered (if they use a newer engine to replace the old and it has more power) or seriously underweight.
Too many variables, and I doubt that Paul Allen wants to go through all that effort just to appease nerdy (yes! Nerdy! I said it! I'm in that group too!) flight sim cartoon jockeys.
The man's a multi billionaire probably. He flies WW2 aircraft FOR FUN. Doubt he cares about the flight sim debates on the modeling of Fw190s and turn radii.
