Throwing some light on rates of turn

Looks like you are doing some intense testing there Crumpp. Maybe a test pilot in a former life.

LOL, Not really...that test would be a death sentence in a real aircraft.

It was a simple test. If you are above ~238mph EAS you should be able to break the airframe in a Spitfire Mk I with a single axis load.

By assymetrically loading the airframe, that speed is greatly reduced. The airframe should turn to confetti.

A dive over 300 mph EAS at full control deflection with an assymetrical load is pretty definative and easy to do.

Did you black out during the pullout?

It started too as I reached the top of the apex of the loop. It did not black out though.

I believe Crumpp is simply referring to incipient spin occurring upon accelerated stall -- which is apparently happening too easily and viciously (for a 109) since the latest patch.

That is it.

LE slats are the aerodynamic equivilent of training wheels. Putting them at the wing tips like the Bf-109 does not do much for raising anything more than the section co-efficient of lift but it does keep the ailerons responsive, make for very good stall characteristics, and it is one of the best anti-spin devices a designer can use.

The stall characteristics of the Bf-109 are very gentle, controllable, and offers plenty of warning:

Are there V-n diagrams for these aircraft available online anywhere?

Not that I am aware of but you can easily make one.

Yeah, but I'm moving across the country in a week, so I don't really have the time at the moment

Can anyone else see those brains working from here!! lol

No, I am afraid they are absolutely not

Well if everyone is complaining that all the aircraft are 25-30 mph off in terms of level speed, it is probably the environment.

First of all, it will be the summer of 1940. The density altitude is much greater than a standard day on a warm summer day.

Almost all of the performance data quoted by folks defending their favorite airplane is performance on a standard day.

At a higher density altitude, you will see a reduction in Indicated Airspeeds and climb rates. That is normal atmospheric effects.

It does not mean the game is modeled wrong.

If Maddox games really models things correctly, it will be very funny to listen to people. Players will be screaming when they hit their boost override and increase rpm over maximum continuous or 1.42ata, or whatever high power/high rpm system their game shape has only to watch the airplane slow down on that hot summer day!

what are the equivalent EAS numbers for the 109? similar?

LOL that's why I said in a previous life.
