The styrene boxes only look fancy because they're still in the stark white compared to all the surrounding green plastic (LOL).

I'm not sure on the traverse, recoil, elevation yet. The gun only has about 10-12 degrees of side to side travel. I'm probably going to forgo on making the gun recoil, and just focus on elevation and side to side with small servos, that's what's gonna matter when battling. In any event I will probably cut the one end off of the Tamiya connectors and replace them with deans plugs
