Perhaps an area that Capt Smiley may look at are the Split - S maneuvers.
With instantaneous / temporarily use of G- limiter override switch currently we can achieve 28 deg. per sec. / 0.2 nm turn radious turns at ~400 kts.
I think that's little to good.
Attached is a tac file
Edit - Oops. I'm getting an invalid file message. What's that?
The file is working correctly in tac view.
The system doesn't recognize .tac files.
Zip it

If you're semi noob then I must be noob.

Thanks jojo!
So here is the file.
Currently, at 5000 ft, full fuel, clean configuration the ITR is 24 / 25 deg. at 350 kts.
With the use of the G - limiter, from my observations, we are still limited to the 25 deg TR but at a wider speed regiment. ex. starting a turn at 440kts, 25 deg is available from around ~ 420 kts at ~380kts the g - limiter is disengaged (to avoid to much speed bleed) and the '' normal '' 24 / 25 deg. TR kicks in. (see the third turn on one of the attached files).
The trick with the Split S is that we can increase further the turn capability to the above mentioned numbers.

It doesn't bother me at all. In the "other sim", which as been largely tested by real crews, the max ITR at 5000ft and corner speed is 27°/s (off course, it's peak, you can't sustain it).

And at 350kt CAS you're close to that corner speed.

I might be wrong, but wasn't the delta wing design created to allow high speed low drag, while still retaining low speed performance?

Delta wing or not isn't the end of the story. Look at the Mirage III, landing speed is 180kt+, light Mirage 2000 can go down to 140kt on final.

I would say high sweep angle gives good high speed performance.
But usually delta wing also gives low wing loading, combined with other characteristic (vortex at high AoA) give high lift at high AoA.

Fly By Wire and relaxed stability allowed to make the most out of it.

Mirage 2000 key requirements were high rate of climb, and high speed performances.
It was designed around available engine (M53).
The relax stability + delta wing allowed to make it lighter, with greater fuel volume (for given airframe weight) and to reach the above 2 requirements.

A big delta will be quite draggy at slow speed. It shouldn't perform as well in terms of controllability at high AoA as it does in game, but it's manageable.

Yes, I wasn't referring to drag, I should have said "low speed lift" instead of "low speed performance". As far as I know, delta wings should allow low drag at high speeds while retaining good lift at low speeds (as a general rule), but at the cost of higher drag caused by angle of attack, meaning more speed loss at turns...
