I currently have MG995 servos in the shoulders. When running off a 12v 7a battery without the forearm and claw attatched I can get his upperarm to go up and behind his head fine. When I add his forearm and claw and try the same thing and the arm slips back down when I try this. Do my servos not have enough torque? Or not getting enough power? Attached is a rough idea of what im trying to do. I would like the arms to hold above his head for roughly 10-20 seconds. The claws will not be moving just there for show for now.
