air to ground ( morphing object properties )

[Lordremcok]

Well I got an idea but i cannot do it after im sure it is duable.

I want to make a plane with wings that can be packed after landing ( on picture -it is supposed to be a plane from the rear )
But I have to change the properties FROM AIR ATTRIBUTES TO CAR ATTRIBUTES, SIMULATE IT, OR PREVENT THE PLANE FROM TAKING OF WITH THE WINGS CLOSED )

Can anyone give me a hint on this
