IMPORTANT INFORMATION ABOUT EPP FOAM

The P-51D Mustang EP is constructed of molded EPP foam. While we suggest using 5 minute epoxy for assembly, you can use C/A to make building time quicker.

We don't suggest using any type of C/A accelerant or "Zip-Kicker" since these products can damage the factory-applied paint.

Do not use any harsh solvents to clean the airframe, such as Acetone. Harsh solvents will damage the factory-applied paint and most likely melt the foam. It is okay to use rubbing alcohol. If you want to add more painted details to your airplane, use water-based acrylic paints and test on a scrap piece first.

TIPS FROM THE PROS

Test-Fitting the Parts

Make sure to test-fit the parts together before applying glue. This will ensure that the parts fit properly before gluing them together.

Storage and Transport

We do not suggest storing your airplane in an extremely hot environment (like the back of your car in direct sunlight) for any length of time. The extreme heat could damage the foam parts and possibly damage the fragile components of the radio control system or the battery.

Cutting the Hinge Slots

When cutting the hinge slots in the control surfaces, hold a straight edge against the side of the control surface to keep it from flexing and bending. Keeping the control surface straight will make it easier to cut the hinge slots along the centerline.

Gluing Smooth Surfaces

When gluing anything that has a smooth surface, like plastic or metal, roughen the gluing surface lightly with 220 grit sandpaper. This will allow the glue to stick better.

Motor Downthrust

We suggest adding approximately 2º of motor downthrust. Follow the motor mounting section carefully, so that you don't overlook this important step.

Elevator Center-Trim

We suggest that you center the elevator by holding a straight edge along the bottom of the elevator and adjusting the pushrod so that the elevator is level with the bottom of the stabilizer. This will make the airplane trim better in flight. Follow the Balancing and Control Throws section carefully, so that you don't overlook this important step.

KIT CONTENTS

We have organized the parts as they come out of the box for easier identification during assembly. Before you begin assembly, group the parts as we list them below. This will ensure that you have all of the parts before you begin assembly and it will also help you become familiar with each part.

FUSELAGE ASSEMBLY

YOU'LL NEED THE FOLLOWING PARTS FROM THE KIT:

❑ (1) Left and Right Fuselage Halves with Rudder ❑ (2) Pushrod Support Tubes

YOU'LL NEED THE FOLLOWING TOOLS AND SUPPLIES:

❑ Thin C/A ❑ 5 Minute Epoxy ❑ Modeling Knife ❑ Scissors ❑ Electric or Hand Drill ❑ 1/8" (3.2mm) Drill Bit ❑ Ruler

STEP 1: INSTALLING THE PUSHROD SUPPORT TUBES

❑ (1) Hex Nut Mounting Plate ❑ (1) M3 Hex Nut

❑ 220 Grit Sandpaper with Sanding Block ❑ Rubber Bands ❑ Paper Towels ❑ Rubbing Alcohol ❑ Epoxy Mixing Sticks ❑ Epoxy Mixing Cups

❑ Using a pair of curved scissors, carefully cut away the flashing from

the edges of the fuselage sides that is left over from the molding process.

PRO TIP Scissors work better than using sandpaper to sand the flashing away. Sandpaper will tear the foam and remove the paint from areas that you don't want.

❑ Cut one pushrod support tube to a length of 11-1/2" (292mm) and one to a length of 9" (229mm).

❑ Using a 1/8" (3.2mm) drill bit, carefully drill a pushrod exit hole through

each fuselage half, using the molded slots as your guide.

IMPORTANT Angle the drill bit toward the side of the fuselage halves, so that you make the hole at as shallow an angle as possible. This will allow the pushrod to exit the fuselage as straight as possible and therefore prevent binding.

CONTINUED

IMPORTANT Make sure to glue the longer pushrod support tube into the fuselage half with the rudder.

❑ Glue the one pushrod support tube into the hole that you drilled in

each fuselage half. Leave about 1/4" (6mm) of the pushrod support tubes sticking out from the side of each fuselage half.

STEP 2: JOINING THE FUSELAGE HALVES

PRO TIP To hold the fuselage halves together while the epoxy cures, we suggest using rubber bands. If put over the fuselage sides carefully, they won't damage the foam or the paint. Don't use masking tape to hold the fuselage sides together, because the masking tape will pull away the paint when you remove it.

❑ Test-fit the fuselage halves together. They should fit together with

few or no gaps between the two, and the outside edges of each half should line up evenly.

If the fuselage halves don't fit together properly, carefully remove

☞

any irregularities in the foam using 220 grit sandpaper with a sanding block.

❑ Mix a generous amount of 5 minute epoxy and apply a thin layer to the gluing surfaces on both fuselage halves.

❑ Join the fuselage halves and secure them together firmly, using

rubber bands. Allow the epoxy to set up before proceeding.

WARNING Don't use masking tape to hold the fuselage sides together, because the masking tape will pull away the paint when you remove it.

STEP 3: INSTALLING THE WING MOUNTING PLATE

IMPORTANT During the next two procedures, be careful not to get any glue in the threads of the hex nut.

❑ Press the 3mm hex nut into the wing mounting plate, then apply a

couple of drops of thin C/A to the hex nut to glue it into place.

❑ Glue the mounting plate into the matching molded recess in the

fuselage.

IMPORTANT Remember to lightly sand the gluing surfaces of the mounting plate, so that the glue will stick to it.

TAIL WHEEL INSTALLATION

YOU'LL NEED THE FOLLOWING PARTS FROM THE KIT:

❑ (1) Prebent Tail Wheel Wire ❑ (1) Tail Wheel ❑ (1) Tail Wheel Mounting Bracket

YOU'LL NEED THE FOLLOWING TOOLS AND SUPPLIES:

❑ 5 Minute Epoxy ❑ Modeling Knife ❑ Electric or Hand Drill ❑ 1/16" (1.6mm) Drill Bit ❑ Ruler ❑ Pencil

STEP 1: INSTALLING THE TAIL WHEEL ASSEMBLY

❑ (1) Wheel Retainer ❑ (2) C/A-Style Hinges

❑ 220 Grit Sandpaper with Sanding Block ❑ Rubber Bands ❑ Paper Towels ❑ Rubbing Alcohol ❑ Epoxy Mixing Sticks ❑ Epoxy Mixing Cups

❑ Cut the rudder from the fuselage along the molded hinge line, using

a sharp modeling knife and a straight edge ruler.

❑ Sand a 45º bevel into each side of the leading edge of the rudder.

❑ Drill a 1/16" (1.6mm) diameter hole in the leading edge of the rudder,

2" (51mm) up from the bottom of the rudder.

IMPORTANT Be careful to make sure that you drill the hole perpendicular to the leading edge and be careful not to drill out through the sides of the rudder. If the hole is not perpendicular to the leading edge, the tail wheel will not line up with the rudder.

❑ Cut a shallow groove in the leading edge of the rudder from the hole

down to the bottom of the rudder.

CONTINUED

STEP 2: HINGING THE RUDDER

❑ Slide the tail wheel mounting bracket over the end of the tail wheel

wire.

IMPORTANT Note the orientation of the tail wheel mounting bracket. The mounting tab should face up, as shown.

❑ Test-fit and glue the tail wheel wire into the hole you drilled. When

properly aligned, the tail wheel wire should rest within the groove and the front edge of the tail wheel wire should be flush with the leading edge of the rudder.

❑ Carefully cut two hinge slots in the leading edge of the rudder and

the corresponding locations in the fuselage. Cut one hinge slot 1/2" (13mm) down from the top of the rudder and the other hinge slot 1/2" (13mm) up from the top of the tail wheel wire.

IMPORTANT

centerline.

❑ Apply a thin layer of 5 minute epoxy to one half of each hinge, then

slide the hinges halfway into the rudder, making sure that the hinges are centered and straight. Allow the epoxy to set up before continuing.

IMPORTANT

they're being glued directly into foam, we've found that using 5 minute epoxy to glue them into place works better than C/A.

❑ After the epoxy sets up, apply a thin layer of 5 minute epoxy to the

exposed half of each hinge and to the tail wheel mounting bracket slot in the bottom of the fuselage. Hinge the rudder to the fuselage and push the tail wheel mounting bracket into position. Hold the assembly in place until the epoxy sets up.

❑ After the epoxy sets up, pivot the rudder right and left several times

to ensure free hinge movement.

Make sure that you cut the hinge slots on the

Even though C/A-style hinges are included, because

❑ Slide the tail wheel onto the tail wheel wire, then firmly push the

wheel retainer onto the wire, to hold the tail wheel in place.

COCKPIT DECK INSTALLATION

YOU'LL NEED THE FOLLOWING PARTS FROM THE KIT:

❑ (1) Cockpit Deck ❑ (1) Dowel Mount ❑ (1) Dowel Plate

YOU'LL NEED THE FOLLOWING TOOLS AND SUPPLIES:

❑ 5 Minute Epoxy ❑ Scissors ❑ Electric or Hand Drill ❑ 7/64" (2.75mm) and 1/8" (3.2mm) Drill Bits ❑ 220 Grit Sandpaper with Sanding Block

❑ (1) Metal Plate ❑ (1) Magnet

❑ Paper Towels ❑ Rubbing Alcohol ❑ Epoxy Mixing Sticks ❑ Epoxy Mixing Cups

STEP 1: INSTALLING THE DOWEL PLATE ASSEMBLY

❑ Carefully cut away the flashing from the edges of the cockpit deck that is left over from the molding process.

❑ Glue the dowel mount into the molded recess at the front of the

cockpit deck.

IMPORTANT You'll need to firmly push the dowel mount into position so that the mounting plate is flush with the front of the cockpit deck.

❑ Glue the dowel plate into the molded recess in the fuselage at the

front of the cockpit opening. Again, make sure that the mounting plate is flush with the surface of the fuselage.

❑ After the glue sets up, drill two shallow 7/64" (2.75mm) diameter holes

into the fuselage for the plastic dowel pins.

STEP 2: INSTALLING THE MAGNETIC LATCH ASSEMBLY

❑ Glue the metal plate into the molded recess in the fuselage at the

back of the cockpit opening.

IMPORTANT Make sure to roughen the gluing surface so that the glue will stick to the metal.

CONTINUED

❑ Glue the magnet into the molded recess in the bottom of the cockpit

deck. Again, roughen the gluing surface so that the glue sticks.

❑ Install the cockpit deck onto the fuselage and double-check that it's

aligned and fits correctly. The magnet should hold the cockpit deck securely in place.

IMPORTANT It's possible that there will be a slight bow in the base of the cockpit deck when it's installed. Don't worry about this. It will be straightened out when you glue the canopy into place later.

WING ASSEMBLY

YOU'LL NEED THE FOLLOWING PARTS FROM THE KIT:

❑ (1) Wing with Ailerons ❑ (2) Prebent Aileron Torque Rods

YOU'LL NEED THE FOLLOWING TOOLS AND SUPPLIES:

❑ 5 Minute Epoxy ❑ Thick C/A ❑ Modeling Knife ❑ Scissors ❑ Electric or Hand Drill ❑ 1/16" (1.6mm) Drill Bit ❑ Ruler

STEP 1: INSTALLING THE AILERON TORQUE RODS

❑ (2) Control Horns ❑ (6) C/A-Style Hinges

❑ Pencil ❑ 220 Grit Sandpaper with Sanding Block ❑ Paper Towels ❑ Waxed Paper ❑ Rubbing Alcohol ❑ Epoxy Mixing Sticks ❑ Epoxy Mixing Cups

❑ Carefully cut away the flashing from the edges of the wing that is left

over from the molding process.

❑ Cut the ailerons from the wing along the molded hinge lines, using a

sharp modeling knife and a straight edge ruler.

❑ Glue one control horn onto one end of each torque rod wire. Make

sure to roughen the gluing surfaces of the torque rod wire first.

IMPORTANT Double-check the orientation of the control horns. When the torque rods are installed into the molded channels in the bottom of the wing, the control horns should be lined up straight, so that you'll be able to install the pushrods and clevises.

CONTINUED

STEP 2: HINGING THE AILERONS

❑ Apply a couple of drops of machine oil between the torque rod wires

and the nylon bearings. This will help prevent you from accidentally gluing the torque rod wires solid if any glue gets between them and the nylon bearings.

❑ Glue the torque rods into the molded channels in the bottom of the

wing, being careful not to get any glue between the nylon bearings and the torque rod wires.

❑ Sand a 45º bevel into the top and bottom of the leading edge of

each aileron.

❑ Drill a 1/16" (1.6mm) diameter hole in the leading edge of each

aileron, 13/16" (20mm) from the inboard edge, then cut a shallow groove from the hole out to the inboard edge for the torque rod wire.

IMPORTANT Notice that the hole should be drilled slightly below the centerline of the aileron. This is okay because the torque rod is positioned lower, too.

❑ Working with one aileron for now, carefully cut three hinge slots in

the leading edge of the aileron and the corresponding locations in the wing. Space the hinges as shown, then glue them into the aileron, making sure that they're centered and straight.

Allow the epoxy to set up before proceeding

☞

❑ Cut out a piece of waxed paper and slide it between the torque rod

wire and the wing.

The waxed paper will prevent gluing the aileron to the wing when

☞

you hinge it.

CONTINUED

❑ Apply a thin layer of 5 minute epoxy to the exposed half of each

hinge and to the end of the torque rod wire and into the hole and groove in the leading edge of the aileron. Hinge the aileron to the wing and hold the assembly in place until the epoxy sets up.

❑ After the epoxy sets up, pivot the aileron up and down several times to ensure free hinge movement, then repeat the previous

procedures to hinge the second aileron to the wing.

WING MOUNTING

YOU'LL NEED THE FOLLOWING PARTS FROM THE KIT:

❑ (1) Dowel Mount ❑ (1) Dowel Plate

YOU'LL NEED THE FOLLOWING TOOLS AND SUPPLIES:

❑ 5 Minute Epoxy ❑ Modeling Knife ❑ Electric or Hand Drill ❑ 7/64" (2.75mm) Drill Bit ❑ 220 Grit Sandpaper with Sanding Block

STEP 1: INSTALLING THE DOWEL PLATE ASSEMBLY

❑ (1) Wing-Screw Doubler Plate ❑ (1) M3 x 40mm Machine Screw

❑ Paper Towels ❑ Rubbing Alcohol ❑ Epoxy Mixing Sticks ❑ Epoxy Mixing Cups

❑ Glue the dowel mount into the molded recess at the back of the

radiator scoop on the wing.

IMPORTANT Firmly push the dowel mount into position, so that the mounting plate is flush with the back of the radiator scoop.

❑ Glue the dowel plate into the molded recess in the fuselage, at the

back of the wing saddle. Again, make sure that the mounting plate is flush with the surface of the fuselage.

❑ After the glue sets up, drill two shallow 7/64" (2.75mm) diameter

holes in the fuselage for the plastic dowel pins.

CONTINUED

STEP 2: MOUNTING THE WING

❑ Glue the wing-screw doubler plate into the molded recess in the

leading edge of the wing.

❑ Drill a 7/64" (2.75mm) diameter hole through the wing, using the

hole in the wing-screw doubler plate as a guide.

IMPORTANT Make sure to drill the hole straight down and not at an angle.

YOU'LL NEED THE FOLLOWING PARTS FROM THE KIT:

❑ (1) Horizontal Stabilizer with Elevator Halves ❑ (6) C/A-Style Hinges

❑ Cut a hole through the wing saddle to open up access to the hex nut

in the wing mounting plate.

❑ Place the wing into the wing saddle and secure it into place, using

the M3 x 40mm machine screw provided.

STABILIZER INSTALLATION

❑ (1) Prebent Elevator Joiner Wire

YOU'LL NEED THE FOLLOWING TOOLS AND SUPPLIES:

❑ 5 Minute Epoxy ❑ Modeling Knife ❑ Electric or Hand Drill ❑ 1/16" (1.6mm) Drill Bit ❑ Ruler ❑ Pencil

❑ 220 Grit Sandpaper with Sanding Block ❑ Paper Towels ❑ Rubbing Alcohol ❑ Epoxy Mixing Sticks ❑ Epoxy Mixing Cups

CONTINUED

STEP 1: ALIGNING AND INSTALLING THE STABILIZER

❑ Carefully cut away the flashing from the edges of the stabilizer that is

left over from the molding process.

❑ Cut the elevator halves from the stabilizer along the molded hinge

lines, using a sharp modeling knife and a straight edge ruler.

❑ Slide the stabilizer into the fuselage and center it by carefully

measuring out from each side of the fuselage to each end of the stabilizer (at the trailing edge only for now). When the stabilizer is centered, both measurements will be equal.

❑ While holding the back of the stabilizer in place, to keep it from

moving side-to-side, measure the distance between the tips of the stabilizer and the tips of the wing. Pivot the front of the stabilizer until both of these measurements are equal.

When both of these measurements are equal, you're assured that

☞

the stabilizer is square to the wing.

❑ When satisfied with the alignment, place a couple of marks on the stabilizer, so that you can realign it easily when you glue it

back into place.

❑ Remove the stabilizer and cut a shallow notch in the back of the

stabilizer mounting slot for the elevator joiner wire.

❑ Slide the elevator joiner wire into the slot, then glue the stabilizer

into place, making sure to realign it with the marks you drew previously.

PRO TIP Because the stabilizer has to slide into place through the fuselage, apply epoxy only to the stabilizer. This will prevent the epoxy from spreading over the entire length of one half of the stabilizer when you slide it into place.

STEP 2: HINGING THE ELEVATOR HALVES

❑ Sand a 45º bevel into the top and bottom of the leading edge of both

elevator halves.

CONTINUED

❑ Drill a 1/16" (1.6mm) diameter hole in the center of the leading edge

of each elevator half, 1" (25mm) from the inboard edge, then cut a shallow groove from the hole out to the inboard edge for the elevator joiner wire.

❑ Carefully cut three hinge slots in the leading edge of each elevator

half and the corresponding locations in the stabilizer. Space the hinges as shown, then glue them into the elevator halves, making sure that they're centered and straight.

Allow the epoxy to set up before continuing.

☞

❑ Hinge the elevator halves to the stabilizer, using the same techniques

that you used to hinge the ailerons to the wing.

IMPORTANT Remember to sand the elevator joiner wire to roughen the smooth surface and to slide pieces of waxed paper between the elevator joiner wire and the stabilizer to prevent gluing the elevator halves to the stabilizer.

MOTOR INSTALLATION

YOU'LL NEED THE FOLLOWING PARTS FROM THE KIT:

❑ (1) Spinner ❑ (1) Motor Mounting Stick

YOU'LL NEED THE FOLLOWING TOOLS AND SUPPLIES:

❑ 5 Minute Epoxy ❑ 1.5mm Hex Wrench ❑ Adjustable Wrench ❑ Modeling Knife

IMPORTANT This section shows mounting two different types of brushless motors. Step 1A shows the installation of the KMS 31/09 brushless Outrunner motor, using the KMS stick mount adapter. Step 1B shows the installation of the radial mounted Xtra brushless motor. Follow the step that matches the motor type you're using. If you're using the Phase3 Models 370 motor and gear box, installation of that motor onto the motor mounting stick is similar to step 1A.

STEP 1A: INSTALLING THE MOTOR - KMS BRUSHLESS OUTRUNNER OR SIMILAR

❑ (1) Motor Mounting Plate

❑ Ruler ❑ Pencil ❑ Epoxy Mixing Sticks ❑ Epoxy Mixing Cups

❑ Loosen the grub screw from the side of the motor mount, then

carefully, but firmly, pull the motor mount off the motor.

IMPORTANT Be careful not to damage the motor wires.

CONTINUED

❑ Install the KMS motor mount adapter (available separately) onto the

motor, using the machine screw, hex nut and washer included with the adapter.

❑ Carefully trim one end of the motor mounting stick at a slight angle

(about 1/16" (1.5mm)), so that when the motor assembly is mounted, the motor will have approximately 2º of downthrust.

❑ Install the motor assembly onto the end of the motor mounting stick,

using two small wood screws (not included). You may also need to use glue if the screws don't hold the motor assembly tight enough.

❑ Install your propeller onto the motor, then push the spinner over the

end of the motor shaft, making sure that it fits securely into place.

IMPORTANT There are two molded channels in the fuselage that the motor assembly can be installed in. Most users will need to install the motor assembly into the upper channel. Install the motor assembly so that the spinner lines up with the top of the fuselage.

❑ Slide the motor mounting stick assembly into the upper molded

channel in the fuselage. When aligned properly, there should be a 1/8" (3mm) wide gap between the front of the fuselage and the back of the spinner. You may need to cut the motor mounting stick shorter to achieve the correct fit.

IMPORTANT You'll need to solder extensions onto the motor wires to reach into the cockpit area where your ESC will be mounted.

❑ When satisfied with the fit and alignment, glue the motor mounting stick into the fuselage.

STEP 1B: INSTALLING THE MOTOR - XTRA BRUSHLESS OR SIMILAR

The Xtra brushless motor features a rear-mounted propeller adapter and an aluminum radial mount that's compatible with the predrilled holes in the motor mounting plate. The spinner that's included is only compatible with 3mm threaded propeller shafts. When using the Xtra or similar motor, you will need to purchase an after-market compatible 1-3/4" (45mm) diameter spinner.

❑ Install the propeller adapter and the radial motor mounting plate onto

your motor, using the screws provided with your motor.

CONTINUED

❑ Install your motor onto the motor mounting plate, using three wood

screws (not included).

IMPORTANT Place a 1/16" (1.5mm) thick washer (not included) between the two top mounting arms and the plywood plate (A), to angle the motor down. This will give the motor approximately 2º of required downthrust.

IMPORTANT There are two molded channels that the motor assembly can be installed in. Most users will need to install the motor assembly into the upper channel. Install the motor assembly so that your spinner lines up with the top of the fuselage. It's a very tight fit between the edges of the motor mounting plate and the inside of the fuselage. You may need to enlarge the opening slightly in the front of the fuselage, so that you can slide the motor mounting plate assembly into place.

❑ Slide the motor mounting plate assembly into the upper molded

channel inside the fuselage. When positioned properly, the front edge of the propeller mount should be 1/8" (3mm) in front of the front of the fuselage. You may need to cut the motor mounting plate assembly shorter to achieve the correct fit.

IMPORTANT You'll need to solder extensions onto the motor wires to reach into the cockpit area where your ESC will be mounted.

CONTROL SYSTEMS INSTALLATION

YOU'LL NEED THE FOLLOWING PARTS FROM THE KIT:

❑ (3) Pushrod Wires ❑ (2) Control Horns with Backplates

YOU'LL NEED THE FOLLOWING TOOLS AND SUPPLIES:

❑ Thin C/A ❑ 5 Minute Epoxy ❑ # 1 Phillips Head Screwdriver ❑ Wire Cutters ❑ Needle Nose Pliers ❑ Z-Bend Pliers ❑ Modeling Knife ❑ Electric or Hand Drill

STEP 1: INSTALLING THE ELEVATOR AND RUDDER SERVOS

❑ Install the elevator and rudder servos into the fuselage. Use a couple

of dabs of 5 minute epoxy to secure them into place.

❑ (4) Clevises ❑ (6) M2 x 16mm Wood Screws

❑ 1/16" (1.6mm) and 5/64" (2mm) Drill Bits ❑ Airplane Stand ❑ Ruler ❑ Pencil ❑ 220 Grit Sandpaper with Sanding Block ❑ Epoxy Mixing Sticks ❑ Epoxy Mixing Cups

Because the size of servos differ, you may need to cut the servo mounting hole larger to fit your particular servos.

☞

IMPORTANT Both servo output shafts should be toward the front of the fuselage.

CONTINUED

STEP 2: INSTALLING THE ELEVATOR AND RUDDER CONTROL LINKAGE ASSEMBLIES

❑ Make a Z-Bend in one end of one pushrod wire.

❑ So that you can adjust the length of the pushrod after it's installed,

carefully make a V-Shaped bend in the pushrod wire 2-1/4" (57mm) behind the Z-Bend.

❑ Cut away all but one arm from a servo horn, then attach the pushrod

wire into the outermost hole in the servo arm.

You may need to enlarge the hole, using a 1/16" (1.6mm) drill bit,

☞

to fit the pushrod wire.

❑ Center the elevator servo (right-side servo), then slide the pushrod

wire into the pushrod support tube and attach the servo arm to the servo, making sure that it's centered.

IMPORTANT You may need to cut the pushrod support tube shorter so that it doesn't interfere with the V-Shaped bend in the pushrod wire.

❑ Repeat the previous procedures to bend and install the rudder

pushrod wire.

❑ Cut a support plate for the two pushrod support tubes from a scrap

piece of balsa, then glue it to the sides of the fuselage and the pushrod tubes.

❑ Install one control horn onto the bottom of the right elevator half, in

the molded recess, using the wood screws and backplate provided.

IMPORTANT Be careful not to overtighten the wood screws. You don't want to crush the foam.

CONTINUED

❑ With both the elevator and the servo arm centered, cut off the pushrod

wire 1/8" (3mm) in front of the control horn.

❑ Double-check that both the elevator and the servo arm are still

centered, then slide one clevis over the end of the pushrod wire and snap it into the outermost hole in the control horn.

❑ Glue the clevis to the pushrod wire, using a couple of drops of thin C/A.

IMPORTANT Before installing the clevis, make sure to sand the gluing surfaces of the pushrod wire, so that the glue will stick securely.

❑ Repeat the previous procedures to install the rudder control horn

and clevis.

Like with the elevator control linkage assembly, the clevis for the

☞

rudder should be installed into the outermost hole in the control horn.

❑ With the servo arms centered, double-check that both the elevator and the rudder are centered. If they aren't centered, you can

center them by adjusting the width of the V-Shaped bend in the pushrods. Opening the bend will lengthen the pushrod and closing the bend will shorten the pushrod. Use a pair of needle nose pliers to make your adjustments. Move the control surfaces back and forth several times to ensure that the control linkage assemblies do not bind. They should operate smoothly in both directions.

STEP 3: INSTALLING THE AILERON SERVO

❑ Install the aileron servo into the wing. Use a couple of dabs of 5

minute epoxy to secure it into place.

IMPORTANT The servo output shaft should be toward the trailing edge of the wing.

Because the size of servos differ, you may need to cut the servo

☞

mounting hole larger to fit your particular servo.

STEP 4: INSTALLING THE AILERON CONTROL LINKAGE ASSEMBLY

❑ Cut the remaining pushrod wire in half, then make a Z-Bend in one

end of each pushrod wire.

❑ Carefully make a V-Shaped bend in each pushrod wire 1" (25mm)

behind the Z-Bends.

❑ Install the pushrod wires into the outermost holes in your servo arm.

❑ Center the aileron servo and attach the servo arm to the servo,

making sure that it's centered.

CONTINUED

❑ Install the clevises onto the pushrod wires, using the same technique

that you used to install the clevises onto the elevator and rudder pushrod wires.

MAIN LANDING GEAR INSTALLATION

YOU'LL NEED THE FOLLOWING PARTS FROM THE KIT:

❑ (2) Prebent Landing Gear Wires ❑ (2) Main Gear Wheels ❑ (2) Landing Gear Mounting Brackets

YOU'LL NEED THE FOLLOWING TOOLS AND SUPPLIES:

❑ 5 Minute Epoxy ❑ # 0 Phillips Head screwdriver ❑ 220 Grit Sandpaper with Sanding Block ❑ Paper Towels

❑ (2) Wheel Retainers ❑ (4) M1.5 x 4mm Wood Screws

❑ Rubbing Alcohol ❑ Epoxy Mixing Sticks ❑ Epoxy Mixing Cups

STEP 1: INSTALLING THE LANDING GEAR MOUNTING BRACKETS

❑ Glue the landing gear mounting brackets into the bottom of the wing.

IMPORTANT Make sure that the predrilled hole in each mounting bracket is toward the center of the wing.

STEP 2: INSTALLING THE LANDING GEAR WIRES

❑ Firmly push the landing gear wires into the slot in the mounting

brackets.

IMPORTANT The landing gear wires are bent forward slightly at the base. Make sure that you install them with the bend facing forward.

❑ Install the M1.5 x 4mm wood screws to hold the landing gear wires to

the mounting bracket.

CONTINUED

STEP 3: INSTALLING THE WHEELS

❑ Slide the wheels onto the landing gear wires, then firmly push the

wheel retainers onto the wires to hold the wheels in place.

FINAL ASSEMBLY

YOU'LL NEED THE FOLLOWING PARTS FROM THE KIT:

❑ (1) Clear Canopy

YOU'LL NEED THE FOLLOWING TOOLS AND SUPPLIES:

❑ 5 Minute Epoxy ❑ Modeling Knife ❑ Scissors ❑ Electric or Hand Drill ❑ 5/64" (2mm) Drill Bit ❑ Airplane Stand ❑ 220 Grit Sandpaper with Sanding Block

❑ (1) Decal Set

❑ Paper Towels ❑ Rubbing Alcohol ❑ Epoxy Mixing Sticks ❑ Epoxy Mixing Cups ❑ Soldering Iron ❑ Solder ❑ Heat-Shrink Tubing (Assorted Sizes)

IMPORTANT The mounting locations of the airborne equipment shown in this section are based on our particular setup. The mounting locations for your setup may differ. The final mounting locations will depend on where your airplane balances. In most cases, you'll want to mount the battery at the front of the cockpit floor and the receiver and ESC right behind the battery.

STEP 1: INSTALLING THE ELECTRONIC SPEED CONTROL

❑ Connect your ESC to your motor. Make sure to use heat-shrink

tubing to insulate the solder joints.

❑ Mount your ESC to the cockpit floor, using a piece of double-sided

foam tape (not included).

STEP 2: INSTALLING THE RECEIVER

❑ Run the antenna out the bottom of the fuselage and secure it into place, using pieces of clear tape (not included).

❑ If your ESC features an on/off switch, mount it in a convenient place

on the side of the fuselage.

❑ Plug the elevator, rudder and ESC leads into their proper slots in

your receiver, then mount your receiver to the cockpit floor, using a piece of double-sided foam tape (not included).

IMPORTANT You'll need to make a hole in the cockpit floor for the aileron servo wire.

CONTINUED

STEP 3: INSTALLING THE BATTERY

STEP 4: INSTALLING THE CANOPY

❑ Mount the battery to cockpit floor, in front of the ESC and the

receiver, using a piece of hook and loop material (not included).

IMPORTANT In most cases, the battery will need to mounted as far forward in the cockpit floor as possible.

❑ Using a pair of scissors, carefully cut out the canopy along the molded

scribe line.

❑ Using 220 grit sandpaper with a sanding block, carefully sand the

edges of the canopy smooth and straight.

❑ Cut out and apply the instrument panel decal to the cockpit deck.

❑ Glue the canopy to the cockpit deck.

IMPORTANT Make sure that the cockpit deck is flat when you glue the canopy into place. This will ensure that there are no gaps between the cockpit deck and the fuselage.

STEP 5: APPLYING THE DECALS

❑ Using a clean cloth, wipe the airframe down completely to remove any dust, debris and oil. We suggest using rubbing alcohol to

wipe the airframe down in the areas where the decals will be applied.

❑ Cut out each of the decals and apply them using the box cover photos for reference.

If any air bubbles form under the decals when you apply them, use a T-Pin to puncture the bubble and release the trapped air,

☞

then press the decal down.

THIS COMPLETES THE ASSEMBLY OF YOUR NEW P-51D MUSTANG EP.

PLEASE READ THE NEXT FEW PAGES FOR INFORMATION ON BALANCING,

CONTROL THROWS AND SETUP TIPS.

BALANCE POINT AND CONTROL THROWS

BALANCE POINT:

The Center of Gravity (C/G or Balance Point) is 3" to 3-1/4" (76mm to 83mm) back from the leading edge of the wing, measured at the fuselage sides.

IMPORTANT It might be necessary to add some weight to the front of the airplane to get it to balance. We suggest using a small amount of self-adhesive lead weight stuck to the inside of the fuselage, right behind the front of the motor opening. This small amount of weight does not affect the overall performance of the airplane. Do not fly the airplane tail heavy.

WARNING Do not balance the airplane further back than recommended or the airplane will be very difficult to control, especially in pitch. An uncontrollable crash could result!

A NOTE ABOUT TRIMMING THE ELEVATOR:

CONTROL THROWS:

Test Flying

Ailerons: 1/2" (13mm) Up & Down

Elevator: 5/8" (16mm) Up & Down

Rudder: 1" (25mm) Right & Left

For Sport Flying, we suggest simply increasing the

Test Flying control throws in 1/8" (3mm) increments,

until you're satisfied with the result.

Sport Flying

THE CONTROL THROWS ARE MEASURED FROM THE WIDEST POINT OF THE CONTROL SURFACES

PREFLIGHT CHECK AND SAFETY

●

Check the operation of the throttle

If you're using a computer radio, you may need to increase your throttle channel's EPA setting to result in full power. (Refer to

☞

your radio system's operating guide for further information.)

●

Check the condition of the transmitter batteries. They should be fully charged.

●

Check every glue joint in the airplane to ensure that everything is tight and well-bonded.

●

Double-check that you've installed and tightened all of the servo horn retaining screws.

●

Double-check that the battery is properly secured into place. There's nothing worse than the battery coming loose during flight.

●

Double-check the balance of the airplane. Do this with the battery installed and the airplane ready to fly.

●

Check the control surfaces. They should all move in the correct direction and not bind.

●

If your radio transmitter is equipped with dual rate switches, double-check that they are on the low-rate setting for your first few flights.

●

Check to ensure that all of the control surfaces are moving the proper amount in both low and high rate settings.

●

Check the receiver antenna. It should be fully extended and not coiled up. Do not cut the receiver antenna shorter or the range of your radio control system will be greatly reduced.

●

You should complete a successful range check of your radio equipment prior to each new day of flying, or prior to the first flight of a new or repaired model.

●

You should not knowingly operate your R/C radio system within 3 miles of a preexisting model club flying field without a frequency sharing agreement with that club.
