I have a few questions on some servos I'm looking at getting possibly. What I'm wanting to do is for Halloween to try and make something similar to a destroyed robotic arm I could wear that is able to be moved with a joystick. (Pretty much like in Terminator 2, being that the goal would be a Terminator.)
I was also planning on being able to re-purpose them later for other projects if I felt like it. (qudra/hexa pod, reprap, etc) The thing is, I'm not sure how well these would work. They say they are 9g servos, Would I need something strong then this to lift something like a hollowed out dowel rod or maybe some semi-thick plastic? Those would probably be the materials I would be using to create the part that people would see, so it'd have to lift that at least.
If they aren't strong enough, could using two of them together for each axis (x and y rotational) make it possible to use them for what I need?
Thanks for the help. Oh, and if you need more specifics, here is the link to what I would be buying. (Also note, I have practically no money, so I need stuff on the cheap. I figure roughly $2-$3 per servo is an extremely good price.)

Halloween is quite fun around my house. I just thought it'd be cool to do. One year we did a fake car wreck with my brother in front of my sisters old chevy truck, put one side on a ramp, and she had a dent in the bumper/grill/hood from hitting a deer, my brother fit and made it look like it was only his upper body between the tree and the truck. We also put a fog machine inside the engine compartment for smoke. Scared the crap out of a few people that year.
Anyway, I'm rambling, so it's time for me to stop talking now. Yet again, thanks if you can educate me on servos a little more.
