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.
Sorry, this is off the wall, but do you still need the original motors and gears? Jstarne helped me out with parts from his projects but Id love to have some spares for my Omnibot2000s just in case!
Pls get back with me.

Another thing. Are you using an ez-b v3? Is the servo wired directly into it? If its run directly off the ez-b v3, the servos getting low amperage, and 5v. It can take 900mah and 7.4v.
A tower pro will lift the arm with nothing in it but once it has to lift the weight of two servos plus the arms it is a different ball game.
@Jstarne1 I want to double check before I order them but would you say the power hd 1501mg would be able to handle the weight, to do what I want?
My hearoid (Omnibot 5402 body) can just about manage to move it's arms using MG995s, these are shorter and lighter arms than the 2000. I'd definitely upgrade the servos.
Does it buzz when it holds/slips? If so you are on or past the maximum torque. If not then check you have secured the horn to the servo and the arm to the horn correctly.
@ Rich Yes, the servos buzz which made me think they didn't have enough torque. Since i did pick up a omni 5402 ill end up using the MG995's on that

Also, d.J. has two of them. A little one and a BIG one. There are many in the Project Showcase section.
good Luck!
