Thanks. I checked everything out and the motor/gear works. After cleaning up a corroded battery connection everything functions, but with two hitches: The left RC control lever runs the gun. Move it up and gun fires. Move it down and gun goes up, then down, and fires when it gets to bottom position. Move it left and right and nothing happens, but a sound effect can be heard. Any way to rewire is to the up motion/down motion are separately controlled. and it doesn't automatically fire at the bottom position?

Thanks again!
