Sukhoi Su-27/30/33/35/37 Flanker series & Su-34 Fullback - History, Design, Performance & Dissection (Part 2)

Not gonna lie to you man, I legit thought it was another fix entirely.

So it’s the adjustment that they did a while ago, but they are just officially announcing it now, got it.

Yea pretty much

Wasn’t that because of the extreme lift though? This seems to be about the elevators.

Gaijin try to get Su-27 correct challenge (impossible.)

yes just for a reminder, this change happened on 31/12/2025.

And the flankers have remained that way since. they are just putting it out on official change log(which can always be delayed about somethings)

It’s basically fine.

What makes it feel bad or sluggish compared to some of the other jets is their over-performance.

Things like the F-16 can min radius fight the F-18 seeing as they have relaxed stability instead of unstable stability. Exceeding the AOA limits on the F-16 irl would lead to a practically unrecoverable spin.

16 also sustains too much G at high speeds it would seem but I need more testing to know for sure.

Man IASM RITA is the perfect one.

Just did some testing and the F-16A overperforms in every metric by significant margins.

Sustaining almost 1G more in level turns than it should at various speeds and altitudes.

The ITR when using the AOA limiter is also much more than it should be reaching 7G at .47 Mach at sea level when it should only pull 5.8-6G under the exact same conditions and weight IRL.

So do other planes (su27 is pretty badly overperforming in sustained turn rate as well). If everything overperforms then gaijin doesn’t care

That doesn’t when i compared it the the SU-27 manual. Where it does its only by small margins.

The F-16 for example can sustain say 19 D/S at a speed where it should only sustain 17.

Also achieving several D/S more in ITR too. 21 D/S vs 24 D/S

What speed? Also wouldn’t this depend on the limiters for both aoa and g?

Not in this instance. But the AOA limit being 25 is generally accepted. I tested G below what the max was to test lift at X AOA and it has much more lift than it should.

You can’t use local host values, you have to do heading / time for degrees per sec as wtrti uses an incorrect formula to calculate it

not to inerrupt you two

but…

Summary:

.55 Mach at 5000 feet should have only resulted in 7G yet I achieved 7.7G.

…47 Mach should have resulted in 6G i got 7G sea level

Yes yes lol but I was just pointing out that the flankers FM is fine its just other jets are way overperforming.

It’s not it’s significantly over performing in STR at high speed

That was before they fixed it recently.

They did not. There was a fix to it’s extremely ridiculous high speed STR and they did reduce it but it is far off of the values in the Su-27 manual.

Interesting, so its still sustaining more than it should lol. The FM devs don’t really seem to have much of a clue these days.

At least its not the Alpha Jet, in game it sustains like 6.5-7G when irl it struggles to sustain 4.
