I just wonder, is the Spit in this sim modelled correcty?
According to this site, and speeds that is a pilot able to achieve in Rl and this sim...maybe not
http://www.fourthfightergroup.com/eagles/spit9v109g.html

Even compared to FW-190 D9 that is supposed to be superior aircraft over any Supermarine Spitfire.

Comments wanted please.

Depends on what respect you say superior. A D9 and an XIV both have different advantages over each other as does the IX over the D9 and vice versa.

As for dives, you'll find the IX in real life could go faster than any other WW2 prop plane due to the wing design which ironicly gave it a good climb also.

That page is talking about dive acceleration.

If you want some figures on Spitfire dive speed, you could look at the manual (460 mph limit at low level, mach 0.85 at high level), or this result from one of the RAE's high speed research flights:

The Spitfire did not have very good dive acceleration. It had very good dive speeds, faster at high altitude than any other prop fighter of the war.

Edit: just read through the page again (it's been changed since the last time I read it, I think) and it does talk above dive speed as well. The figures it gives:

Spitfire:

Between S.L. and 20,000 ft. -450
20,000 and 25,000 ft. -430
25,000 and 30,000 ft. -390
30,000 and 35,000 ft. -340
Above ..................35,000 ft. -310


109G

Up to 3 km (9,842 ft.) 750 km/h. (466 m.p.h.)
At 5 km (16,404 ft) 700 km/h. (435 m.p.h.)
At 7 km (22,965 ft) 575 km/h. (357 m.p.h.)
At 9 km (29,527 ft) 450 km/h. (280 m.p.h.)
At 11 km (36,089 ft) 400 km/h. (248 m.p.h.)

The Spitfire has a large dive speed advantage on the data presented on that page.

Dive acceleration for Spits is way overmodelled in FB. They keep on anything like glue. Same for Yaks and stuff. They just fall back when they reach their Vne. That kinda sucks.

I was surprised after reading about how the Spitfire was not able to dive with FW190's to read that Pierre Closterman dove with a FW190 in his Spitfire IX and caught him at the bottom.

The problem, as has been highlighted by Willey is acceleration...there doesn't appear to be much difference. So diving away doesn't gain you much. Unless you are already well ahead...then you can at least buy yourself some time.

Still, diving away was never a perfect tactic, even in WWII...the thing was this:

1) You could dive away in large numbers and head for home. That'd mean that the attacking group would have to follow the retreating group. If only one of the attackers followed he'd get swarmed later.

2) It was more likely not to follow a dive away because you would loose your position with the rest of the flight or you would possibly hurt your chances to fly home by increasing your distance at a time when your fuel tank may be getting near a critical point.

In a dogfight server...no worries like those. So I don't think that we have dives away from combat like they did historically so that is ALSO skewed.
