two arms, each about 12-18in long with a 5 oz weight connected to the end.

Those weights are going to have a heck of a lot of energy and if anything goes out of balance or gets detached this could be very dangerous.
I knew physics class would come in handy someday. I was looking at stall torque to choose that motor, the other ones on that site seemed to weak to get the arms up. I don't seem to see that specification on most of the other motors I looked at.
I don't think it will be that dangerous at the speeds I'm imagining.
What speeds are you imagining?
Torque isn't important for the arms to raise (assuming low friction), only angular velocity. To get up to speed quickly you doneed more torque - so how quickly do you want to change angular velocity?
