Ares War Copter
I know that this may not be the most meta based, or physics based copter, but I find it pretty attractivedesign-wise, I worked on it for some hours.
It's chasis may not seem very solid, but it is tri forced in the interior, rod forced in the weakest points, and some pieces are built in light cubes, that give it more healt and less mass.
For weapon choice I customized 2 options:
-the original Ares, with 5 plasma devastators, and 3 nano healers, that provide other fliyers with good resistance against AA tanks
-The WarBord Ares copter, with bigger rotors in the arms and the tail, and switching from the nano healers to the missile launcher, to take out flyers aswell (they were a pain in the butt)
Hope you enjoy it!
And as always, you can find it in the robocraft factory, with and without guns :3
