Here's the old quote angelsandair resurrected:
Frankly, you silly, delusional twits, I don't see how it's possible.
The Brewster company went under during the war, almost 55 years ago. Do you have any idea how difficult it is to find performance data on an aircraft like the Buffalo after all that time?
Even aircraft like the Corsair, which was far more popular with warbird enthusiasts than the despised and denigrated Buffalo, suffers from a lack of data. Francis Dean has done as much research into World War II fighters as any author in our times. As just one example of the problems he encountered in trying to gather data for his tome "America's Hundred Thousand" Dean states that no F4U roll rate data could be found above 290 mph IAS.
Cry in your beers if you must, but I strongly suspect that we will never see the Brewster in AH simply because there is not enough reliable, documented flight dat in existence to allow HiTech to create a viable flight model.
Twits.
angelsandair,
Since Brewster Model 239 was included in the vote for a new aircraft after this quote was written I can't really see how this is relevant in anyway. Pyro and HTC sure seems to think it's possible to model Brewster with enough degree of accuracy...
...but I'll address the arguments in the quote anyway...
So, since there's is no roll rate data for the F4U above 290mph IAS, how can it be in the game?

We know it's Vne at most alts is higher than that.

In one roll rate thread (from 2004) Pyro said that he hasn't seen any (numerical?) roll rate data for La-5...and yet we also have that aircraft in the game.
Good, fairly accurate educated guesses can be made about lot of things. In case of La-5's roll rate, other aircraft with similar design can be looked at for reference and subject aircraft's structures can be studied which both help to arrive to a good conclusion.
And unlike Shuckins assumes, very accurate data and handling charateristics describtions actually exist in a report supplied by the Brewster Aeronautical Corporation to Finland with the Brewsters. Mr. Jukka Raunio has extensively quoted that document in his book Lentäjän Näkökulma II (Pilot's Viewpoint II) and Camo has send this information to Pyro. Only thing that really is missing is (again) numerical roll rate data but there are some describtions about how Brewster rolled which can be taken into account.
The following and a lot more data is available about the Brewster 239:
- Structural limitations (IIRC -4/+9 G, don't remember the safety coefficients off hand, can be found from the document I mentioned)
- Reliable speed/climb curves
- Stall speeds (clean/"dirty") /airfoil data /lift coefficient
- Extensive CoG-data
- Accurate handling characteristics describtions (not just pilots anecdotes, they are based on the test pilot's reports)
- Accurate fuel consumption figures
- The obvious technical specs (wing area, hp, weights)
...I'd guess the above alone is enough to model an aircraft to AH2's FM-engine.
