I did some work on the Puma tonight, more specifically it's mounted rail gun. The ammo box is just tacked on there temporarily to show you how it all fits together. There are a few more details to add, but this is the jist of it. This will be remotely operated from the co-pilots computer console which will be visible in the cockpit.
A couple things I'm finding tough about building somrething pretty much from scratch is building the components that I need multiples of like upper and lower a-arms. Also I'm really looking forward to painting this so in my head I'm like, "Looks great, lets go paint it! Wait........there are more pieces to be made and test fitted 1000 times before we can paint anything."
