Test purpose:
Measure the max G load and elevator authority of several planes diving at 550mph.

Test conditions:
Terrain dueling, base A1, Alt 15k.
All planes loaded with 50% fuel, taking off by North.
All planes diving vertically untill 550mph, trimmed for speed, then recovering pulling stick as hard as possible without manual trim.

Results:
Ta152H - 6.5g for a fraction of second.
190D9 - 6g for a fraction of second.
190A8 - 6g for a fraction of second.
Typhoon - Well above 9g substained, after some seconds pulling > 9g, wings broke.

Video:
Diving and max G at hi speed test

Conclussion:
Just a question, how is possible so noticeable difference between any 190 and Typh elevator control at hi speeds?

Isn't it that the typhy has those big fat wing ... I mean reaaaaaaaally thick.

Try the P47, good luck to rip the wings... oh wait... 550 you will be compressing in a P47:rolleyes: no test for you.

"All planes diving vertically untill 550mph, trimmed for speed"

Am I reading this right to mean you were trimming the planes into the dive?

JAB, once diving, combat trim enabled, you can see that in the film.

Frenchy, no compression at all with Typh at 550, it is even able of 9G substained.

Don't trim into the dives Mandoble, this will affect some planes more than others.

it doesnt matter the typh can hit 600 with no compression...........

ki61 has very strong wing - they modelled it well.

I'm not saying whether the Typhoon is right or wrong, just that as a matter of policy during diving tests, trimming into the dive is not a great idea because it will affect some airplanes more than others.

No compression is one thing, but > 9g substained at 560mph is another. Both, IMO, a complete exageration.

Frenchy, I did the test with P47D30. No compression at 550mph and also able of 9G substained.

Why 190 family can handle only 6 or 6.5 for a fraction of sencond while P47 and Typh can substain 9G, where is the big difference?

But we all know the Tiffie was a supreme fighter at all altitudes. We also know for a fact, that is suported by aeorynamic facts and theories and physic laws that the thicker the wing is, the better high speed handeling.

Give it up Mandoble, not worth it.

Well, this field is plowed and harrowed to a fine powder.

Are you just going to continue to talk amongst yourselves or are you going to do something?

i wonder if there are any german companies working on a WWII flight sim...apparently VVS planes in IL2 are invincible & accoring to this @least one US plane is overly tough in this US built sim...of course the Jug had a reputation for sturdiness that i've never of about the 190, but i've never read a book by a 190 driver...
