Hey here are some concepts to use the Junkion Blacksmith Infinity Warfare set to act as a poor man's upgrade to Bruticus Maximus. If you want Bruticus Maximus to have articulated arms you would need to use the tanks as arms. Basicly from vehicle mode you swivel the turret to face backward then untab the tracks and and move them upward and twist the waist away from the front of Bruticus. This will make it so the tank figure's hip and knee joints act as a double jointed elbow for Bruticus. The helocopter figures I haven't found a way to give Bruticus extra articulation. Let me know what you guys think.
