Is there a way to solve this issue?

[citizen67]

The wheels into the tarmac, using Yakarov's AV-8B 83...

Thanks in advance.

It's not a real issue, I've seen worse on other terrains where it is due to wrong Tag value for the tile in the TFD. Can be fixed with TFDtool. Just live with it.

[+hi ho silver]

Try increasing the  RollingRadius= in data ,landing gear .

[+Cliff7600]

Drop the fuel tanks ! that's heavy load

and check the tyres pressure at the next station.
more seriously ->
If you start to edit the rolling radius of the wheels, do it with an unloaded plane at minimum fuel level.
Or then it will "float above the ground" when not loaded.

I tend to use a lowered value for the rolling radius of the wheels to have the visual effect of a slight squashing. Like every real tire, it increases the surface in contact with the ground.
I see no issue at all, except it's not realistic seen like that. But it's nothing compared to planes sinking in the runway at touchdown...

and...

ShockStroke=
SpringFactor=
DampingFactor=

are also some values that can effect the way a plane stands on the ground.

Check everything or don't touch anything 

As long as the rim is not touching the ground it's safe ! xD

More seriously: thanks everybody. I'll try out, now.

[+Cliff7600]

Well, according to the 3D model (USMC_AV-8B-Plus_93)

[MainGears]
...
ShockStroke=0.16   // is the exact value of the animation, so I wouldn't change it.
...
RollingRadius=0.465    //  The radius value from the 3D model is 0.3275, so the data.ini file give the main gears already 0.275 meter bigger than they really are.

My two cents are : RollingRadius=0.32 and try to edit the "SpringFactor=" and "DampingFactor=" values to have the result you want.

And don't forget the LeftOutrigger and RightOutrigger values as well.

[+Cliff7600]

Okay, I take back what I said, it's not fun and there is an issue. Though it's a very inconspicuous one.

There is no way to solve the issue without creating another in the process.

The problem is there's only one animation AnimationID=7 for all parts of the landing gear : front wheel, main wheels, and left and right outriggers.
And each has a different length of displacement when you play the animation.

As I am a long time "screw up the 3D model by ini" supporter, I made some shock absorbers by data.ini.
But it totally ruined the scissors movement for each  landing gear leg.

Engine shut OFF, back to the ground

While rolling, taking off

and I don't know if it's worth the editing (?)

The following part is off-topic, but that could be useful and BACK-UP YOUR FILES FIRST !

To make some nice vertical take-off :

Fuel lower than 100% and no loads in the loadout menu because it's too heavy

In the cockpit.ini file :

to give back the 0.16 meter taken from the CG value because the cockpit position is right on spot.

and I would say the [Engine5] would need some editing too but maybe it's not that important.

Think twice before editing anything

[Wrench]

there's a LOT of stock 3W aircraft with 'flat tires' too (the Phantoms come to mind). They all seem to work fine. As someone that's also done the LG editing, and really fouled things up, sometimes its just not worth it!! 

seems to fall into the 'better left un-messed with' category!! :)

[citizen67]

Well, you all are convincing me to enter in the " better left un-messed with" world...

[+guuruu]

Yup, we don't like revolutions .

[+Cliff7600]

The to-do list is looong for this bird (ini files)
Though it's fun. And maybe one day it will be totally messed-up xD

The stock harrier is working much better (after very few ini edits...).

[yakarov79]

Something like this? 5 minutes in notepad and max....

Did any of you try to contact modder to address those issues?

 

 

By the way...to one of the posts above.

With data from this mod vertical take-off and landing is already possible.

As far as I'm concerned, I don't want to bother people. Sometime just a copy-paste in 3D Max seems too much asking.

On my instal, it's not enough to solve the problem as the aircraft stalls when slowing down under the stall speed.
So I had to edit even more to have something similar to the stock Harrier (stall speed and stall behaviour).

Hard mode settings

 

If you're open to suggestions, you can rework the GunPod mesh, because it is not symmetrical and the plane doesn't fly straight when used.

And mostly, if you don't try by yourself you don't learn 
And I learned by doing many edits on this great model and it was really good fun !

Next time just shoot pm. If it is about Harrier than I am all ears

Well, the gun pod is asymmetrical and that is how it should be. Ammo in the right pack, gun in the left pack. 

I would be nice to find a way to limit firing above certain airspeed (depends on engine model 150/250kts)

[rlwicker1967]

Okay, I was a real pilot. We learned in Flight School that the tires were always underinflated so they wouldn't burst at the higher altitudes with lower atmospheric pressure.
