I finally got the d@mu aircraft to sit still. It was the Dampening Ratio [on the contact section] that needed fixing. All I had to do was set the ratio to 1.
However, still does not solve the so-called sinking aircraft issue.
The model no longer flips, but it still appears halfway buried into the ground with the nose slighty downward [not by much]. No crashes or violent movements this time.
I tried to increase the static_cg_height in the aircraft.cfg file, but it made it worse. It caused my model to DROP and then crash as it hits the ground.
I then tried to set a higher, negative value on the vertical axis of all the wheel contacts. Well, it made the model finally rise from underground. But it's nose would then fall down into the dirt and cause a crash.
I can't figure out what's the actual solution to this.
Here is a sample of the model's aircraft.cfg file. Can you figure out the culprit?

I only showed the needed parts of the file. This is what's currently used for the model.
