Sadly the mod is incopatible with the airplane physics mod because after every start of the plane the plane changes the type of the plane and has not the same weapons anymore

You sure you got the right thread? :D
1 - my mod isn't officially updated for 0.18,
2 - this mod runs only on game load and simply adds new crafting tab and changes AAI's items to use this new tab instead of old one.
There is no reason for it to cause any incompatibilities with other mods during the gameplay itself (even Earandel's vehicles are touched in bare minimum way, that is to say their crafting tab propery is changed - nothing else).
