Nessim:
I've done what I can and it's not much. The nosegear's compression isn't modeled visually, so it won't react to the aircraft's motions.
What I did was reduce the compression by about 70 % - it has a lot of movement; kinda looked like a busted shock to me.

It has a tendancy to 'gallop' on the ground. So I reduced that, changed the height position of the wheel so it sits firmly on the ground and shouldn't rise or sink too much under heavy braking/accelleration. Here's the fix:
point.0= 1.000, 9.917, 0.000, -6.95000, 1574.803, 0.000, 0.632, 37.140, 0.199, 2.500, 0.407, 5.000, 5.000, 0.000, 0.000, 0.000
In your .cfg, go down to [Contact Points] and replace the first line with the one I just gave you. It should solve your problem.
