the only thing i did with the physics is add the banshees meta to it. making it fly. I did this because of 2 things. 1 it has wings so flying would be nice. and 2 im in the process of making a mod for blood gulch in wich i added a litte ?station? (cant think of the right word right now) wich you teleport from one of the bases to the top of the level and im putting 4 of these up there.
