If you have an ARF with split elevators and you want a stronger elevator control setup than the traditional torque-rod, single-control-horn technique, create a Y-split in the control rod as shown. Bend music wire to the needed shape, wrap the ends of the two arms with uncoated copper wire to bind them to the single control rod that extends to the servo, and solder-fill the wrapped joint.
