GAU 8 PC powder cannon testing

This is my design prototype for a miniature GAU 8 Avenger cannon to be used for an RC A10 to simulate Audio and Visual effects. It uses a simple air pump to propel talc or baby powder from the barrel and an attachment for sound. This project is still under development but as you can see from the video it just needs small changes to be practical. Fairly lightweight, the unit will add some really nice effects to a future model.
