Section 6: Installing the TailCONTINUEDStep 2. Trim away the covering over the elevator and rudderlinkage openings on both sides of the fuselage at the tail. Lookcarefully, and you will see the slots. Trim away the coveringusing a sharp hobby knife.Step 5. Attach the wing and measure from the front tips of thehorizontal stabilizer to the wing tips. Each should be the samedistance from the wing. Make any adjustments necessary tomake sure the horizontal stabilizer is aligned with the wing.Step 3. Carefully remove any the tape holding the elevators tothe horizontal stabilizer and remove the elevators. Measure thecenter of the fuselage at the forward bulkhead where the front ofthe horizontal stabilizer will rest, and the plywood plate at therear or the fuselage. Using a ruler, mark the center line of thehorizontal stabilizerEDGE <strong>540</strong>EDGEUltra Aerobatic 1.20 ARF<strong>540</strong>Ultra Aerobatic 1.20 ARFStep 6. When you are satisfied with the position of thehorizontal stabilizer, use a felt- tipped pen or pencil to mark thebottom of the horizontal stabilizer next to the fuselage. Removethe horizontal stabilizer and trim away the covering 1/8” insidethe marks you made. Being very careful no to cut or evenscore the balsa wood below the covering. This willprovide for a more secure epoxy joint when the horizontalstabilizer is epoxied to the fuselage.Step 4. Trial fit the horizontal stabilizer onto the rear of thefuselage. Install the elevators to check the distance between themand the rear of the fuselage to make sure there is no binding.Note that the fit is very close. Use masking tape to hold thehorizontal stabilizer in place while making measurements. Checkto see if the elevators will function without binding when thehorizontal stabilizer is centered on the marks made in Step 3.Step 7. Reinstall the wing and mix approximately 2 ounces of30-minute epoxy. Apply the epoxy to the tail where the horizontalstabilizer will be mounted and to the bare wood of the horizontalstabilizer. Reposition the horizontal stabilizer to the fuselage,18
Section 6: Installing the Tailmaking sure you align it with the reference marks madepreviously. Then align the stab so that it is square with the wingwhen sighted from the front. Wipe away any excess epoxy withrubbing alcohol and a paper towel. Be sure there is no epoxy inthe area where the two tail pieces will go. Hold in position withmasking tape. Allow the epoxy to cure.CONTINUEDCaution: Do not cut into the wood below the covering.This will weaken the structure.Step 9. Mix approximately 1 ounce of 30-minute epoxy andapply to the vertical stabilizer and tail post where it contacts thefuselage and horizontal stabilizer. Be sure to apply epoxy to thebase of the vertical stabilizer. Insert the vertical stabilizer into thefuselage tail area and wipe away any excess epoxy with rubbingalcohol and a paper towelStep 10. Mix approximately 1 ounce of 30-minute epoxy.Apply epoxy to both fairing blocks and mount to the horizontaland vertical stabilizers. Wipe away any excess epoxy. Usemasking tape to hold the two fairing blocks in place.Step 8. Carefully remove the tape holding the rudder to thevertical stabilizer. Trial fit the vertical stabilizer to the fuselageand trial fit the two fin fairing blocks. Some trimming of thefairing blocks may be necessary to obtain a good fit. Hold inplace with masking tape.Mark the position where the vertical stabilizer meets thetailpieces with a felt-tipped pen or pencil. The mark should leavea slight indentation in the covering. Carefully remove the verticalstabilizer and tail pieces. Remove the covering 1/8” from whereyou made the marks, using the procedure as described in Step 6.19
