So using a friction spring in sp would be good for planes because they dont Bounce but do you use damper for that? because in the simplecheats (btw very useful for xml editing) It says that it is the friction of the spring. I will test and see and maybe finally i will make good custom lg and not rush it just to upload a plane. Also i want to test something that would delay the doors but idk how to do that but i will experiment.

I will test now and say what i come up with.
