Like I said I'm out of town and can't check my copy of America's Hundred Thousand where I get my weight figures from. All the B339s were several hundred pounds heavier than the B239. Exactly how much depends on the different sub variants and the configuration of individual airframes. Anyone with a copy of AHT could check the exact weights. I'm just wondering why RAF pilot would be flying a Dutch Brewster? If you are so certain of it I'm sure you can provide a source which confirms it? All I've ever heard from this particular mock dogfight is that it was a RAF Buffalo Mk.I. It is true that the Dutch Buffalos were better machines than the RAF planes from the Belgian order. Anyway, it doesn't matter either way which B339 it was as all of them are still different airplanes when it comes to weight/power compared to the B239.


I have a copy of AHT here, according to a couple tables on Pg. 441.  The British Brewster had an empty weight of 4268.2 and a "normal" gross weight of 6112.2.  Another variant which is listed as "Dutch.2nd Ord." has an empty weight of 4282.0 and normal weight of 6094.5.  The F2A-3 in USN service comes in at 4765.3 empty and 6518.6 normal.  By comparison the B239 is listed at 3744.1 empty.  On the next page is lists gross weights ranging from 5014.1 to 5314.1 depending on load (guns and fuel).

Thank you Soulyss! :aok

That pretty much covers it. There are some differences due to what is listed in those weight break downs. For example that B239 is with less fuel than the full (160gal) load and obviously not with 4*50cals...not that the guns make much difference. Like I said before the difference is still several hundred pounds.

If it's not too much trouble could you check the power output of the Buffalo Mk.I?

I'm still interested in hearing what a Dutch Brewster was doing in China when it was supposed to be in Dutch East Indies... :)

*GASP* Chalenge was wrong?  Oh wait, he was wrong in the Iwo Mustang thread too.  Par for the course.

He won't post again in this thread either.  That's what he does, spouts techno blabble with no actual facts, gets called on it by those who actually have facts, and then disappears off to another thread to do the same thing.  Like when he said a nuclear bomb being detonated at the sea bed in the gulf of mexico would cause a 1000 foot wall of water over Louisiana.

I guess I could settle alot of this debate by just asking what the weight/hp ratio of the Brew we have in game is...

What ever your in-game test weight is per the E6B divided by 1000 HP MSL.  You'd have to interpolate for higher altitudes until you got to 16000 feet, then again above.

Well I don't see how it could settle much but it's rather easy to find out...

It's ~2,55kg/hp with max. take-off weight. Very close to a FM-2 for example.

If you want a figure in lbs to the last decimal you can check the weight in game and divide it with 1000hp. Then you'll get what it is from sea level to 3000ft. The MAP gauge shows the MAP for 950hp setting but the FTH is for the 1000hp setting.

EDIT/Stoney beat me to it./EDIT
