And you wonder why you never see a P-40 above 12,000 feet.

Now i know they all dive away at alt.

AND I LIKE HIGH ALTITUDE FIGHTS !!!!

Thanks for your efforts Mr.Fork!! Big !!

Man, I always thought that the 190s were fast accelerating planes. Compared with contemporary Spitfires, at both deck and alt, I don't think there's anyway AH 190s can ever be described "it out-accelerates the Spitfires"...

Kweassa · « **Reply #4 on:** April 07, 2003, 03:38:34 AM »

If possible, it'd be really great if we can see test results of 50%, 75% and 100% fuel..

It'd be interesting to see how the list changes again with different fuel load..

Why the tremendous difference between F4F4 and FM2?

Mister Fork · « **Reply #6 on:** April 07, 2003, 08:27:22 AM »

I ran those two planes through the same test twice GH because I was surprised too. I also retested the 109F4/G2 and the P-38 just to make sure the numbers were correct.

The F4F-4 for it's age halls ass. Who knows why? I doesn't even have WEP compared to the FM2.

Kweassa - I tried that actually - giving a few aircraft more fuel on the top five and reran the tests. The results are not 'much' different - it just takes longer to accelerate.

Maybe the same thing that happened with the Brewster? Too much weight in the "upgrades" and no significant increase in horsepower.

Except I believe the FM2 actually weighed a little less than the F4F4 and had more horsepower. I guess it could have something to do with the gearing in the supercharger, but I would think the FM2 would be superior.

Puke · « **Reply #9 on:** April 07, 2003, 05:22:35 PM »

Yep. FM2 was quite a bit lighter and had an increase in hp over the F4F-4.

Wait a minute, why is the FM2 down at the bottom of the list. I'm guessing these aircraft got transposed in the list.

HFMudd · « **Reply #10 on:** April 07, 2003, 06:13:11 PM »

Or the FM2 and F4F got transposed in the AH look-up tables. Sounds like a good one to ask HTC about.

Mister Fork · « **Reply #11 on:** April 07, 2003, 06:22:16 PM »

I just re-did the FM2 test. Yep, she's a slow beast. 57+ seconds.

Can anyone explain why the FM2 is a slow tard compared to the F4F-4?

funkedup · « **Reply #12 on:** April 07, 2003, 06:35:25 PM »

IIRC the FM2 had a much lower rated altitude than the F4F-4.

vorticon · « **Reply #13 on:** April 07, 2003, 09:31:47 PM »

according to that the hurri2c is only 1 step slower to accelerate than the mosquito...i always thought that was a very fast medium bomber...weird

Zigrat · « **Reply #14 on:** April 07, 2003, 10:55:16 PM »

doesnt make much sense though funky, take a look at the climb rate chanrts for the 2 of em. Does the fm2 match its advertised climb rate at that alt?
