Section 13: Installing the Rudder andElevator LinkagesParts Needed• Fuselage• 12" threaded 4-40 rods (3)• 6" threaded 4-40 rods (2)• Wood pushrods (25 1 ⁄8") (2)• String• 4-40 clevis (5)• 4-40 nuts (5)• Clevis clips (5)Tools and Adhesives Needed• 6-minute epoxy• Hobby knife• Masking tape• Ruler• Drill• Drill Bit: 1/8"• Pliers: standard and side cut• Felt-tipped pen/pencilStep 3. Locate two 12" 4-40-wire pushrods threaded on oneend. Using a felt-tipped pen, measure and mark them at 8 1 ⁄2"from the threaded end. Align these marks with the end of woodenpushrod where the holes are drilled from Step 2. Mark the wireswhere they cross over the holes drilled in the pushrod. The 4-40wires will be glued on to the opposite sides of the woodenpushrod to create a "Y" for controlling the elevators.AStep 1. To construct the elevator pushrod, locate one of thehardwood pushrods (25 1 ⁄8"). Measure in 2" from one end andmake a mark centered on the pushrod. Make another mark at 3"on the same end of the pushrod.BStep 2. Use a 3/32" drill bit to drill through the pushrod at themarks made in the previous step. Make sure these holes aredrilled parallel to each other.Step 4. Use pliers to make a 90-degree bend in the wires atthe mark made in the previous step. Next, measure 1/4" from the90-degree bend and cut off the excess wire using side cutters ora Dremel tool and cut-off wheel.41
