Why does my player pawn not have collision?

So I have created a pawn that has proper collision settings based on everything I can find and yet it does not seem to collide with anything. Not objects, static meshes, or otherwise. To test my theory I used the model in the twin stick shooter sample. I just swapped my mesh with the existing ship and the same problem occurs. Also to note, I am having to down size the model to .05 of original size. Not sure if that matters at all.
