MiG-29 A C or G Low Alt High Speed Vibration/Shakes

[ElvisDaKang]

I am running DCSW 2.56

 

Take off

 

Go to 10K-15K  or so but not necessary really to go that high but humor me............. and go to 10K.

 

Go to burner if not already in it. 

DIVE

 

DONT HIT THE GROUND.

 

When I do this the aircraft starts a overall aircraft SHAKE or vibration like the jet is coming apart. If you are in the cockpit the jet is no longer flyable visually in the sim.

 

WTF is up with this. I am familiar with the SHAKE setting in MISC settings.

 

There is NO mention of this on this website or on GOOGLE or on Youboob. 

 

Thanks !!

AND obviously this is with regard to ANY variant of the MiG-29  A , C or G all perform in this regime of flight as described. 

IS this OLD ass FC3 flight modeling for this particular aircraft. SU-27 and SU-33 do not do this .

You need to post either a track, a video, or certainly far more detailed means of repoducing this.   Saying 'go to 10k, light the cans and dive' means nothing.   Dive how?  What angle?  When do you pull out of the dive?  What speed?  How much g?

Are your flaps down?

Unable to reproduce it with the information provided. Smooth flight all the way down each of three attempts.

No, it's Professional FM since 2018.

Without a video or a screen shot.................................. I will make this VERY simple.

 

MiG-29 A, C or G

 

Created single aircraft mission. Took off seal level from Anapa. Full burner take off - rotate , gear and flaps up. Climb to 400M and continue acceleration in max burner.

 

At 1250kph the SEVERE cockpit shaking starts it doesn't start from bad and gets worse - IMMEDIATELY the cockpit control panel................. as a visual reference...... is rolling back and forth 90 degrees from left to right in an INSTANT  i.e it takes milliseconds for one cycle of this to occur. GGTharos. Pretend you are in the bottom of a washing machine looking up and the machine is on spin cycle and just outside the washing machine you are trying to read the headlines on a newspaper. 

 

WHILST This is happening if you go to external aircraft few the plane is quivering hard in roll axis not more than about 3-4 degrees L-R roll. 

 

I friend of mine down the street does NOT experience this in his 29s. 

 

I will provide a vid as soon as I snag some record software to do so.

ANSWER

 

Sim was set to GAME MODE.  WHY I do not know - I do not fly in it normally.

 

It does beg the question - WHY with GAME mode selected .....would the MiG-29 behave like that at 1250 kph?  The other supersonic FC3 aircraft don't.

 Kinda hard to take you seriously when you are so grossly ill informed on such a basic point...

   Irrelevant. They're different aircraft that don't have to fly the same or exhibit similar behavior. Again, hard to take somebody seriously when they are acting under such a flawed basic principle.

 

  In general, you're not providing any specific detail on what you're doing/experiencing, let alone why you think it's incorrect. A lot of aircraft shake at the transonic/supersonic regime at low altitude, the air is denser there. Loadout can also affect this sort of this, for example three bags and four missiles are going to have inferior performance to a clean aircraft and be much more prone to adverse characteristics in this flight regime.

I encounter the same problem. In mig29 quick mission, after shooting down the two L39s and turning to the two Su25s, it almost always happens. Here is a short phone shot video of the replay:

Hope it helps the diagnosis.
