I had those aerodynamic balances on the elevators of a 1/4 scale Cap 231EX. I unhooked the servo and added enough finishing nails to the forward end of it to balance the weight of the elev. itself. Also helps stop elev. flutter. I don't know why these are not used more on the bigger models. I've seen on some of the bigger 3D planes, 3 servos to drive the ails. when a servo tab would do it on one servo. Look at the weight and wiring it would save.
