Hello again,
thanks EHood and Alfie for your replies.
Regarding the takeoff problem, it seems that it only happens in the airfield of Belarus, where Monty's 'Eastern Front' is set. I've tried to takeoff from other airfields in other maps, and this strange sinking into the ground doesn't happen. I could make a proper takeoff just as Alfie shows in his pictures. However, the plane still shows a weird behaviour. Just after a mission is loaded, and looking from the cockpit, the plane makes a strange movement, as if it was going down some inches. Another funny thing is that chocks don't work with this plane (they work fine with other Nieuport models).
But the main problem with this plane is the cockpit appearance. Here you can see shots from the cockpits of all Nieuport models in my install:
As you can see, all models seem to be right, with small or big variations with each other, and fine details such as girls pictures attached to some cockpits. They probably belong to the Nieuport update version made by Mission_bug, see:

As you can see from the pictures, the cockpit seems to be an older version, it doesn't fit the other models' cockpits. When I move the mouse, the wires that connect the upper and lower wings begin to vanish, and even do some parts of the wings themselves. There is also an extra grey wing over the upper wing, and some grey bars that connect the upper wing and the fuselage, as if they belonged to other plane. All these items are labelled with red letters in the images above.
Well, I just wondered if someone can confirm if his/her Nieuport 11 seems to be the one it should be. I really doubt I have the correct version. Moreover, the Nieuport 11 has been used by Monty to be the 'stars' of his campaigns 'Symbol of French Pride' and 'The Eastern Front' so I doubt that he used a 'bad' version. It is a pity, because the other Nieuport models look so wonderful!!!
Thanks in advance to the one that solves this mistery!
