Very nice !

But I can't land it...
When the wheels are touching the runway, they seems to be stopped, and he breaks his landing gear...

Any idea ?

I'm not a gret modder, I just helped to translate a part of the game into French, I think, there's a little problem because on the game there is a nose wheel because the gravity centre is between these wheels, if you remove the front wheel and you don't change FM, the V-3 dives because it doesn't have the front wheel and the gravity centre is between main gear and the nose of the plane, so it dives.
That's why they used 4 Mk108(A-1a) or 2 Mk108 and bombs(A-2a), the weight of weapons moves the gravity centre to the front.
I think to solve the problem is, creating a new AC slot with new FM and work on gravity centre.
I think that will help a lot.
