Hinging the Control Surfaces

Required Parts

Fuselage Rudder Hinge (3) Wing panel with aileron and flap (right and left) Stabilizer and elevator (right and left) Elevator torque rod (right and left)

Tools and Adhesives

Hinge glue 30-minute epoxy Sandpaper Mixing stick Low-tack tape Paper towel Rubbing alcohol Petroleum jelly

 Step 1

Locate the stabilizer and elevator assemblies. Note the direction and location of the elevator control horn in relationship to the stabilizer. It is suggested to use a small piece of low-tack tape to mark one of the assemblies so the elevator and stabilizer can be return to their pairing,

 Step 2

Separate the elevator and stabilizer. Remove the elevator control horn and three hinges. Set the stabilizer and hinges aside in a safe place.

 Step 3

Use a piece of sandpaper to roughen the wire from the elevator control horn where it contacts the elevator. This provides a better surface for the epoxy to adhere to when glued in position. Use a paper towel and rubbing alcohol to remove any oils or debris from the wire after sanding.

 Step 4

Thread the nylon horn on the wire so it is flush with the end of the wire and facing the opposite direction of the portion of the wire that will go into the elevator.

Note: You can perform the following steps for both elevator halves with one batch of epoxy. Read through the steps to familiarize yourself with the procedure before mixing any epoxy.

 Step 5

Mix a small amount of 30-minute epoxy. Apply the epoxy to the notch and into the hole in the elevator, as well as to the portion of the wire that will contact the elevator.

Note: Make sure to use enough epoxy to glue the torques rods. If the epoxy does nto ozze out between the torque rod and elevator, you have not used enough epoxy.

7Hangar 9 P-51 Mustang 60 ARF Assembly Manual

 Step 6

Insert the wire into the hole in the elevator. Wrap a piece of low-tack tape around the elevator to keep the wire secure until the epoxy fully cures. While the epoxy cures we can continue the hinging process then hinge the elevator last.

 Step 7

Locate three hinges. Apply a small amount of petroleum jelly to each hinge where it bends to prevent it from accidentally being glued and preventing it from operating correctly.

 Step 8

Insert the hinges into the control surface. Moving the hinge over 90 degrees and pressing the hinge into the surface will set the correct depth for the hinge, as the hinge point will be recessed slightly in the control surface so it operates properly.

Hinge point recessed in control surface

 Step 9

In addition to setting the correct depth of the hinge, this will guarantee that the hinge has been installed in the correct direction. Rotating the hinge could cause the surface to bind, increasing the load on the servo and draining the receiver battery prematurely.

8 Hangar 9 P-51 Mustang 60 ARF Assembly Manual

 Step 10

Apply hinge glue to the holes in the elevator as shown. Make sure to read the instructions on the glue before beginning the hinging process.

 Step 11

Insert the hinges into the holes in the elevator so the hinge point is set back as described in Steps 8 and 9. Make sure to install the hinges correctly. Allow the hinge glue to fully cure before proceeding to gluing the hinges in the fixed surface. This will prevent them from being moved accidentally. Remove any excess glue using a damp paper towel.

 Step 12

Apply hinge glue to the holes in the stabilizer. Slide the hinges into the holes and use a damp paper towel to remove any excess glue. Check that the elevator can move up and down freely. Set the assembly aside to allow the glue to fully cure.

 Step 13

Repeat Steps 1 through 12 to prepare the remaining half of the stabilizer and elevator.

 Step 12

Hinging the rudder follows the same procedure as the elevators. Again, make sure to prepare the hinges and check the operation of the rudder before the hinge glue begins to cure.

9Hangar 9 P-51 Mustang 60 ARF Assembly Manual

 Step 13

Remove the flap and aileron from the wing. Make sure to keep the flap hinges with the flap and the aileron hinges with the aileron as they are different sizes.

Important: Each aileron has a hard point installed in the bottom side of the aileron for mounting the control horn. Make sure to install the aileron so this hard point is located on the bottom of the wing or the control horn could pull away from the aileron and cause the loss of aileron control of your model.

 Step 14

Hinging the aileron is again the same as hinging the elevators and rudder. Make sure the aileron can move freely when the hinges are installed. Remember to double-check that the hard point for mounting the control horn in the aileron is located toward the bottom of the wing.

 Step 15

Apply a small piece of low-tack tape at the tip of the wing to hold the aileron in position. This will help when the flaps are being installed.

 Step 16

Hinging the flaps will take a little finesse as the hinges will be exposed and you will need to adjust the flap so it aligns in the correct position. Test fit the flap in position using the hinges. Adjust the flap so it is in alignment with the aileron on one end and the wing at the other. You will need to adjust the position of the flap and hinges to accomplish this.

 Step 17

Turn the wing over and check that the flap is flush with the top of the wing as well.

Hint: Tape a piece of balsa flat to the surface to help aid in the alignment of the flap to the surface of the wing skin.

10 Hangar 9 P-51 Mustang 60 ARF Assembly Manual

 Step 18

Once you have test fit the flap without glue, you can now remove the flap and use hinge glue to secure the flap to the wing panel. Use small pieces of low-tack tape to hold the flap in position until the hinge glue fully cures.

 Step 19

Repeat Steps 13 through 18 to hinge the remaining flap and aileron of the opposite wing panel.

Aileron Servo Installation

Required Parts

Wing panel (right and left) Servo mounting block (4) #2 x 3/8-inch sheet metal screw (16) Control horn with backplate (2) 2-inch (52mm) safety tubing 6-inch (152mm) threaded pushrod (2) 12-inch (305mm) servo extension (2) Pushrod keeper (2) Clevis (2) Servo (2) Receiver Transmitter Receiver battery

Tools and Adhesives

30-minute epoxy Sandpaper Mixing stick Pliers Covering iron Pencil Clamp (2) Medium grit sandpaper Drill T-pin Ruler Phillips screwdriver: #1 Side cutter Thin CA Felt-tipped pen Pliers Hobby knife with #11 blade Drill bit: 1/16-inch (1.5mm), 5/64-inch (2mm) Rotary tool and cutoff wheel

 Step 1

Remove the aileron servo cover from the wing. Make sure to remove all the tape that was holding the cover in position. You may need to use a covering iron to seal the covering back on the wing and cover before proceeding.

 Step 2

Use a hobby knife with a new #11 blade to remove the covering from the slot in the aileron servo cover.

11Hangar 9 P-51 Mustang 60 ARF Assembly Manual

 Step 3

Use the radio system to center the servo for the aileron. Remove the original arm from the aileron servo and install a 180-degree arm so it is perpendicular to the center line of the servo. You will be connecting the linkage to a hole that is 9/16-inch (14mm) from the center of the servo arm, so make sure your servo arn meets these requirements.

 Step 4

Position the servo on the bottom side of the servo cover so the servo arm is centered in the opening in the cover as shown. The servo must also be parallel to the opening so the arm can move freely through its entire range of movement.

 Step 5

Use a pencil to mark the servo cover for the position of the servo mounting blocks on the aileron servo cover. Make the mark behind the brass eyelets and alongside the servo. Make sure to mark for both blocks without allowing the servo to move on the cover.

 Step 6

Use medium grit sandpaper to scuff the ends of two servo mounting blocks as shown.

Sand this end

12 Hangar 9 P-51 Mustang 60 ARF Assembly Manual

 Step 7

Mix a small amount of 30-minute epoxy. Apply the epoxy to the end of the blocks that were sanded in the previous step. Position the blocks on the servo cover using the marks made previously. Use small clamps to hold the blocks tightly against the servo cover until the epoxy fully cures.

 Step 8

Position the servo between the blocks. Leave a small gap of 1/32-inch (1mm) between the servo cover and servo to prevent vibrations from the airframe from being transferred directly to the servo. Use a pencil to mark the blocks for the four servo mounting screws.

Hint: Place a 1/32-inch (.5mm) spacer between the servo and the servo hatch cover before marking the mounting holes.

 Step 9

Remove the servo. Use a drill and 1/16-inch (1.5mm) drill bit to drill the four holes for the servo mounting screws.

 Step 10

Apply 2–3 drops of thin CA into each hole to harden the surrounding wood. This provides a harder surface for the screws making them more secure when installed.

 Step 11

Use the screws provided with the servo to secure it to the servo mounting blocks. Use a #1 Phillips screwdriver to tighten the servo mounting screws.

 Step 12

Secure a 12-inch (305mm) servo extension to the aileron servo lead. Use string, dental floss or a commercially available connector to keep the two from unplugging inside the wing.

13Hangar 9 P-51 Mustang 60 ARF Assembly Manual

 Step 13

Use side cutters to remove the portion of the servo arm that does not go through the servo cover.

 Step 14

Use a pin drill and 5/64-inch (2mm) drill bit to enlarge the hole that is 9/16-inch (14mm) from the center of the servo horn.

 Step 15

Remove the tape that holds the string in the aileron servo opening. Tie the string to the end of the aileron servo extension. Use care not to accidentally pull the string out of the wing.

 Step 16

Remove the flap servo cover. Use the string to pull the aileron servo lead to the opening for the flap servo.

 Step 17

Use a T-pin to poke through the four holes in the covering in the aileron servo cover. Position the servo cover in the wing and use a drill 1/16-inch (1.5mm) drill bit to drill the four holes for the servo cover mounting holes. Use caution or you could accidentally drill through the top of the wing.

14 Hangar 9 P-51 Mustang 60 ARF Assembly Manual

 Step 18

Apply 2–3 drops of thin CA into each hole to harden the surrounding wood. This provides a harder surface for the screws making them more secure when installed.

 Step 19

Use a #1 Phillips screwdriver and four #2 x 3/8-inch sheet metal screws to secure the servo cover to the wing.

 Step 20

Use a ruler to measure in 215/16-inch (75mm) from the inside edge of the aileron. Use a pencil to make a small mark on the aileron.

 Step 21

Use side cutters to remove the servo horn backplate from a control horn.

 Step 22

Position the control horn on the aileron so the center of the horn is aligned with the mark made in the previous step. When positioning the control horn, align the front edge of the horn with the edge of the fixed surface as shown to minimize any differential of the control surface. Use a pencil to transfer the location for the three mounting screws on the aileron.

15Hangar 9 P-51 Mustang 60 ARF Assembly Manual

 Step 23

Use a drill and 1/16-inch (1.5mm) drill bit to drill starter holes for the aileron control horn. Only drill about 1/4-inch (6mm) into the aileron to avoid drilling through the top of the aileron. There is a hard point in the wing so you will need to be careful when drilling.

 Step 24

Use a #1 Phillips screwdriver to start the three #2 x 3/8-inch sheet metal screws in each hole. Leave about 1/16-inch (1.5mm) of the screw exposed when threading them into the aileron.

 Step 25

After threading the screws into the holes, you will need to apply 2–3 drops of thin CA into each hole to harden the surrounding wood. This provides a harder surface for the screws making them more secure when installed. Skipping this step may not provide a secure mounting of the aileron control horn, which could cause it to fail in flight.

 Step 26

Once the CA has cured, you can attach the control horn to the aileron using three #2 x 3/8-inch sheet metal screws, tightening them with a #1 Phillips screwdriver.

 Step 27

Use a hobby knife with a #11 blade to cut a 1/4-inch (6mm) piece of tubing from the 2-inch (52mm) safety tubing included with the kit. Slide the tubing on a clevis, and then thread the clevis 10-turns on a 6-inch (152mm) threaded pushrod.

 Step 28

Connect the clevis to the center hole of the aileron control horn. Slide the safety tubing onto the clevis so it won’t open accidentally in flight.

 Step 29

With the aileron aligned with the wing tip and aileron servo centered, use a felt-tipped pen to mark the pushrod wire where it crosses the hole in the servo arm that was enlarged back in Step 14.

 Step 30

Use pliers to bend the pushrod wire 90 degrees at the mark made in the previous step.

 Step 31

Use side cutters or a rotary tool and cutoff wheel to trim the wire 3/8-inch (10mm) past the bend as shown. Use a flat file to remove any sharp edges after cutting the wire.

 Step 32

Insert the wire into the hole in the servo horn. Slide the pushrod keeper on the wire, and then use pliers to snap it on the wire to secure the pushrod wire to the servo arm.

Note: You may need to adjust the clevis slightly to align the aileron with the wing tip. Make sure the radio is on and the aileron servo centered during this process.

 Step 33

Repeat Steps 1 though 32 to install the remaining aileron servo and linkage in the opposite wing panel.

Note: The retracts are installed next and prior to installing the flap servos so that you have access through the flap servo hatch to route the retract extensions.

/2-inch (90mm) wheel (2)

3mm x 8mm machine screw (4)

Tools and Adhesives

Side cutters Threadlock String or dental floss T-pin Medium CA Pencil Ruler Drill Pin drill String or dental floss Thin CA Phillips screwdriver: #1, #2 Drill bit: 1/16-inch (1.5mm), 5/64-inch (2mm),

1/8-inch (3mm)

Hex wrench or ball driver: 1.5mm, 9/64-inch, 3mm

 Step 1

Prepare the retract servo by installing the grommets and brass eyelets. Note the eyelets are on the top-side of the servo as shown. Remove the servo horn from the servo at this time as well.

 Step 2

Select a servo arm that has a hole located 11/32-inch (9mm) from the center of the horn. Remove any arms that will not be used using side cutters, leaving only the arm with the hole as described. It is best to trim the arm down as small as possible to fit into the retract mechanism without binding.

 Step 3

Enlarge the hole in the servo horn using a 5/64-inch (2mm) drill bit and pin drill

 Step 4

Place the servo horn on the retract servo so it moves equally from the center position. You will need to use the radio system to cycle the retract servo for this procedure.

 Step 5

Check to make sure you are installing the servo on the correct side of the retract mechanism. The servo will face to the trailing edge when installed.

Note: The next steps will check the operation of the retract mechanism. Do not secure the servo as poor positioning of the linkage or servo could cause the servo to bind causing stress on the radio battery or even damage the servo gears.

 Step 6

With the retract mechanism and servo in the “up” position, check the fit of the servo in the retract frame. The mounting holes of the servo must align with the holes in the frame for mounting the servo. It may be necessary to adjust the length of the linkage to get the mounting holes to align.

 Step 7

Hold the servo in position against the retract frame. Check the operation of the retract using the radio system. When the retract mechanism is in the “down” position the mounting holes should still be aligned. If not, the linkage may need some more minor adjustments in length.

Important: Also make sure the retract mechanism is locking in both the “up” and “down” positions. If not, it may be necessary to prepare a new servo horn with the hole in a slightly different position.

 Step 8

Once the retract is operating without binding and locking in both the “up” and “down” positions, use four 2mm x 12mm machine screws and four 2mm washers to secure the retract to the retract frame. Use a 1.5mm hex wrench to tighten these screws.

 Step 9

Secure a 6-inch (152mm) servo extension to the retract servo using string, dental floss or a commercially available fastener.

Servo Rotation

 Step 10

Pass the extension through the hole in the wing behind the opening for the retract mechanism.

 Step 11

Position the retract mechanism into the wing. Use four 8-32 x 3/4-inch socket head screws and four #8 washers to secure the retract mechanism in the wing. Tighten the screws using a 9/64-inch hex wrench or ball driver. Make sure to use threadlock on all four screws so they do not vibrate loose in flight.

 Step 12

Use a T-pin to poke through the covering of the retract servo cover so they can be located from the top-side of the cover.

 Step 13

Position the retract servo cover over the retract servo. Slide the cover back snug against the wing. Use a drill and 1/16inch (1.5mm) drill bit to drill the two holes for the cover mounting screws. Use care not to drill through the top of the wing when drilling these holes.

 Step 14

Apply 2–3 drops of thin CA into each hole to harden the surrounding wood. This provides a harder surface for the screws making them more secure when installed.

 Step 15

Secure the cover to the wing using two #2 x 3/8-inch sheet metal screws. Tighten the screws using a #1 Phillips screwdriver.

 Step 16

Remove the wheel cover from one of the main wheels.

 Step 17

Check to make sure you have selected the correct strut for your particular wing panel. The scissor mechanism will face to the rear of the aircraft and the flat area on the gear door mount faces out away from the wheel well.

 Step 18

Use a 1.5mm hex wrench or ball driver to loosen the setscrew that secures the axle to the retract strut. Remove the axle from the strut assembly.

 Step 19

Slide the wheel collar from the axle. The axle will now fit into the hole in the wheel. Make sure to install the axle into the side of the wheel with the deeper recess that does not have the screws that hold the wheel assembly together.

Hint: Apply a small drop of machine oil on the axle to allow the wheel to rotate smoothly.

 Step 20

Slide the wheel collar on the axle. Secure the collar using a 2mm setscrew. Make sure to use threadlock on the setscrew to prevent it from vibrating loose.

 Step 21

Slide the axle back in the retract strut. Note that the wheel will face opposite the flat area on the gear door mount. Use a 1.5mm hex wrench or ball driver to secure the axle in position. Make sure to use threadlock on the setscrew to prevent it from vibrating loose in flight.

 Step 22

Snap the wheel cover back on the wheel at this time.

 Step 23

Use the radio system to move the gear to the “down” position. Insert the strut into the retract mechanism and secure it by tightening the screw using a 3mm hex wrench or ball driver. There is a flat area the screw secures to. This will align the strut so the aircraft tracks straight on the runway without excessive wandering.

 Step 24

Use the radio system to move the retract mechanism to the “up” position. Check that the wheel is centered in the wheel well. It may be necessary to adjust the position of the strut in the retract mechanism slightly so the wheel is centered.

 Step 25

Position the gear door as shown in the photo. Use a small drop of medium CA to temporarily tack glue the gear door to the gear door mount. Make sure not to get any CA into the threads of the gear door mount. The CA only needs to hold the gear door in position so it can be marked to drill the two holes for the gear door mounting screws.

 Step 26

Use a pencil to trace the outline of the gear door mount on the gear door.

 Step 27

Carefully remove the gear door from the gear door mount. Use a pencil to draw a center line through the tracing of the mount as shown.

 Step 28

Measure in 1/8-inch (3mm) from each edge of the gear door mount outline and draw a line as shown. The distance between the two lines will be 19/32-inch (15mm) if done correctly.

22 Hangar 9 P-51 Mustang 60 ARF Assembly Manual

 Step 29

Use a drill and 1/8-inch (3mm) drill bit to drill two holes through the gear door as shown. Use care not to tear the covering when drilling through the gear door.

Hint: Placing the gear door on a piece of wood while drilling will minimize any possibility of damaging the covering.

 Step 30

With the gear in the “up” position, attach the gear door to the gear door mount using two 3mm x 8mm machine screws and two 3mm washers. Use a #2 Phillips screwdriver and threadlock to install the screws.

Hint: If the gear door does not align, loosen the screws to reposition the gear door or loosen the setscrew on the gear door mount to align the trim scheme. If that does not work, the holes can be enlarged slightly to make minor adjustment to the alignment.

 Step 31

Repeat Steps 1 through 30 to install the retract mechanism in the remaining wing panel.
