This is the 5th gatling gun I've done. They get better each time. The 1st one I made was 22 lbs. The next 2 were more accurate, but didnt spin. All of them have an intense blue LED. The 4th was more accurate yet and didn't spin. I was finally able to keep the weight down and get it to spin. Total weight is about 9.6 lbs. There a video of it working at the end. I'll be taking this to Wondercon and using it with my Camo ARF. The only thing I'm missing is the 6 nuts on the back circle. I'll get those on tommorrow.
