We are using springs. Without the springs we risk buring out our van door motor trying to hold a tetra up even with our arm not extended. So we added springs to the back of the arm and now we risk burning the motor trying to hold the arm down.. Actually the braking on the victor holds it in place nicely as long as the robot is on, but we have to turn the robot on to make the arm stay down. Makes storage more interesting.
