Issues with the JAS 39 Gripen flight model

No, there are non.

It overperforms in ability to pull AoA which negatively impacts SEP, right?

I guess it’s a mixture of pulling too much AoA for a given turn speed and maybe too much drag while turning.

They couldn’t do the MiG-29 properly. And you’re talking about Grippen, which has very little data

Any news on a bug report for the incorrect FM of the 29 btw ?

It’s been a long time

I want to know when the Gripen is getting buffed. Like MAWS, BOL overhaul and centre line bombs

I can try to report it, but I won’t be available to do so for a couple weeks. I’m waiting on the latest JAS 39 FM changes before I submit the report for that as well.

Mirage 2000 FM was changed its kinda ridiculous how much energy it retains at lower speed but bleeds at higher speed, it shoupd be the opposite. Also the gripen did get some changes throigh the devserver iirc so maybe the sep changed.

Regarding the JAS-39, do you have any material to get the BOL dispensers fixed?

They should work completely different from what they do ingame and got double nerfed for no reason.

They shouldn’t linger as long as normal flares, which they fixed, but the brightness should be extremely high. You also shouldn’t be forced to drop multiple BOL packages at once.

Also: Do you have new sources on the JAS39? Because iirc you mainly drew comparisons between the Gripen and the Mirage 2000 which now has seen a big buff to it’s SEP values.

Its already been reported and with appropriate source materials.

M2K changes might be overdone, unfortunately. We will need to see when I have time to test, or if others can test rn. I have three solid sources for the M2K turn rates and such to compare. The Gripen should follow a similar sustained curve, but the instantaneous capabilities of the canard are going to come with more available AoA, higher rates, but also likely higher bleed depending on conditions. It is complex and difficult to model when the current FM acts unlike that of a canard delta with relaxed stability.

The problem stems primarily from them giving it the correct sustained turn rate but the FM utilizing the canards as though it is a statically stable airframe. This means the canard is providing to overall positive lift when it shouldn’t be… It needs reworked from the ground up and they can’t do that rn.

The F-16 is overperforming some but not to the same degree because the elevators are not contributing to overall lift and it has been amended in other ways that the FM can handle.

Yeah I saw your reports and remember them, I just thought there might be additonal sources that can be used. Because I guess for now, the DEVs decided to make them like this for balance.

Maybe also because of game limitations but with next patches ability to seperate CM’s, we at least won’t waste as many BOL packages anymore.

Take your time mate, seems like a lot of FM are going on recently, if I remember correctly @skilz2kil was working on it as well.

I’m just hoping for a better, more accurate MiG-29 one day ;)

I’m also curious on the gripen FM changes, let’s hope it gets a lit bit less of the UFO feeling like the blk 10.

Yep, i had some irl stuff come up i had to get sorted first haha - i should be able to continue on with what i was doing this week

Was wondering if the gripen for nerfed lately ?

Matched a few guys and felt like it was easier to do something against it, even tho it’s still insanely strong.

I feel like it rate worse than it used to.

Yes:

That’s a good change, it feels way less broken

well sure. but “broken” or not shouldn’t be a factor in changing a vehicles stats, it should be as close to IRL as possible.
Which it might be, i don’t know.

its just a bit sad that now, after this change, the JAS39 has a worse turn rate than the Viggens had before they got theirs changed as well.
So basically the sustained turn rate of the newest plane is now worse than the previous one was before the changes.
(Viggen before was 15.5 deg/s and is now 14.2deg/s. JAS39 turn rate is now 15deg/s)
this seems to low for the JAS39 given this threads discussions on the turn rate.

Iırc some sources states that JAS39 should have 18-20 degree sustained turn rate.
