Here's the bottom section of the Log file with a lot of entries about the MIG21.

I re-installed the MIG pack just in case there was an error but I still get the Mig21 Polka

If it's not a scramble QMB the AI version seems to fly OK,  however if it's a QMB scramble/taking off,  it bounces round then it's engine starts and it just taxis straight in to my plane or goes across country trying to break the land speed record 

And it is ONLY the MiG-21bis that does this the other MIG21's are OK except for a tendency to crash at 45 degrees in to taxiways  when trying to land

My MiG 21 is also bouncing on the ground from this Unified pack.

3D Hook (ClipGear hook) 's positions or orientations problem?
 or
new flightmodel support code problem?

[Whiskey_Sierra_972]

About bouncing I have only tested the NF and R....today I'll test the bis....

[western0221]

About AI bouncing, not only this MiG 21, other jets sometimes become this resonant condition.
In my guess, coming from specific set of weight values and gears' spring stiffness values in flightmodels.

I think I can limit not to come in the resonant condition with any values in FMs in adding new codes for Gear.class.
I'm looking into Gear.class of Engine MOD, I find the limiter to Friction values of each wheels seems not to work as planned.
Friction values are planned between 4,000 - 5,000 (in stock code) or 4,000 - 8,000 (in western patch for heavy jets). But the log in AI bouncing shows it explodes upto 290,000. 

I'll try to make another safety-net those limiters work OK in Gear.class .

[western0221]

Finally I found even any good values in FM Gear, that AI bouncing still comes.

I added a limiter code.
Here is new Engine MOD patch. How is it?

thanks mate, will test out the update today

Sadly the AI MiG-21bis still bounces round at take off

Perhaps it's something specific to that particular plane that is the problem?

[Krauss brs]

Works very well! it just jags a bit near the ground but i solved that by changing the lightning on the landscape and it works just fine!
Actually,i found this,just nickpik but the dragchutes look like this

Arent they supposed to look like this?

i found it strage becouse i have the s2 25 and its dragchutes look like that.
anyway to change the model?

[SAS~Tom2]

OK, since I long lost my fun in Mach 1+ SAS jets aka Migs, I would like to post an informal request here to any code proficient fast jet fan here:
First, many thanks to 4S_Vega for bringing us the IMO best jet FM behaviour for any fast IL-2 jet to date.
    

Late or early in summer last year I stumbled however over a series of reallife Mig-21 cockpit videos which suggest a few prominent shortcomings of our birds here which cannot be solved via simple FM edits:
AOA behaviour in a LanceR video was visibly (gauge in sight) different, and especially roll an pitch was and is different:
Rolls: There is both a momentum aka delay and a much faster roll spin at all seen speeds, RL data assumes even higher roll rates at high super sonic speeds.
Pitch:
The extreme sensitivity of our current Migs cannot be verified by any video I saw, they simply do not have such a quick onset of Gs.

Anyone welcome, all I can do is grab out my last year reference. I post since literally the day I found out about these shortcomings I stopped flying jets in SAS modpacks.

Cheers

Tom

The info from MiG-21 manual and aerodynamics textbooks...

-deltawing has a low but long polare, unlike "conventional" wings - aka rectangle/trapezoide, which means, after some AoA - and it is not much, the lift does not grow anymore, but stays more or less the same, only the drag increases.
-with AoA, the aerodynamic center shifts BACKWARDS for highly swept delta (MiG-21 case, manual confirms)
-by manual, the plane is rather unstable per AoA - to explain shortly - "Cobra, Su-27 style"
-by manual, from 21S on, emptying the nose (last in order) tank means drastical shifts in CoG, making the plane even more unstable, usually too dangerous for landing - so it is basically a "last-resort" tank and during normal flight, you should not touch the fuel in that one.

As my school year is getting to the end, I hope for return to modding, possibly having a further look on the 21's.

Personally I think Vega's FM's are great - no doubts about that. But that is only at low AoA, like up to 10 deg, above that - well - it needs a touch. A big one.


Oh, and for a touche at our modding gods...
Using Lagrange's polynome for creating a polynome describing a curve from a paper manual is... not the best idea due to inaccuracy in the numbers we read from the graph. I know a better method

[SAS~Tom2]

Koty, if yopu want to go for this AFTER your exams - we can talk about it more. I could regather all the sources I kept and contact benitomuso again for permission to the needed tool for you.

Ver. 2.0 news

1) Fixed loadouts for all previous aircraft

2) Fixed gunsights - now they have corrected textures

3) Gunsight functions added for third gen. 21's

4) Fixed weapons - GSh-23 got more realistic balistic and damage values and FAB-100 is now dropped in salvo from the quadaple rack
[You have to surpress classfiles in Vega's weapon mod that are in conflict with ! ! 00_MiG-21_Weapons!]

5) Added new separate classes for: MiG-21SM, MiG-21MFN (this one was a testbed for new features, so I've kept it there)

6) Airbrake now gets reactivated after dropping tanks (this function hasn't been directly confirmed on real plane, might get removed later)

7) Simplified some pieces of the old code

Known bugs

1) Gunsight was calibred for old GSh-23, it is therfore not accurate for the new one.

2) Radar is unable to lock on a target.

3) Start-up dance is still present.

4) Shaking near 0G, especially in rough weather.
