What is the best recoil unit or mabe the easest way to add a recoil to the Stug IV. I've got my ideas but you guys always have good methods.

I favor the Tamiya recoil because I can modify it to function just like the real gun. I can easily make it a fast recoil due to the blast energy and a slow, dampened return to battery. I looks realistic and is a nice touch.
