You probably need to watch out for motors getting hot. They draw a lot of current when still.

A simple variation on Brian's idea is to just retrim your joystick to apply the small amount of power you need to keep the arm from backdriving.
You do have to be careful of which motors you use this with. The CIM's and globes can handle it well, but the Fisher-Price and Banebot 540 motors do not take well to being stalled.
