so now that vehicle welding is official and no more a glitch
i tried to place a pheaton in a phantom and it just went all over the place.
i put it on top and it wasnt flyable (too much mass)
tried banshee and same story (too much mass)
there should be an option to TURN OFF all physics and weights of object what is combined to your vehicle this way you will drive and fly as it should
or also add weight reduction by percent
i would really love this simple feature and am prettysure the forge community will love it too
(sorry for bad english)
