The Mini gun is progressing well. I hve now added the water container and mounted the pump on the outside of the main barrel. It certainly has a unqiue look. Once power is applied via the RF switch on the R6 the barrel will spin. At the same time the strobes trigger in time to the rotating barrel and power is applied to the water pump resulting in a powerful jet of water. The power will come from a small 4.5amp battery probably mounted in one of the battery boxes or added to the shoulder bracket, not sure yet. The tracking system has yet to be built that will allow the gun to pan left and right with the movement of the head, should be easy though.
