• The covering used on your model has the coloring and markings printed directly on the covering.

• The covering has a self-adhesive backing, and it is not recommended to use heat as it may damage the covering.

• Use only mild cleaning agents on the printed fi nish. Denatured alcohol is the most aggressive agent we recommend, but test on an inconspicuous area fi rst. Prolonged use will remove the paint.

• Use tape with care. Anything other than low-tack tape can remove the fi nish, particularly on edges.

• Avoid contact with raw fuel, especially alcohol-based fuels containing nitro methane.

• Remove exhaust residue as soon as practical to avoid staining or damaging of the fi nish. There are two areas on your aircraft that will receive wear under normal use. The fi rst area is where the cowling fi ts over the fuselage hatch, and where the wing fi ts into the fuselage. Placing a piece of clear tape on the wing where it fi ts into the fuselage, and on the hatch underneath the cowling, will reduce the wear on the covering in these areas. Sanding the inside of the cowling smooth will also help prevent wear of the covering under the cowling. BUILDING PRECAUTIONS Prepare the work surface prior to beginning the build. The surface should be soft and free of any sharp objects. We recommend resting the airframe parts on a soft towel or pit mat to prevent scratching or denting the surface of the aircraft.

TRANSPORTATION AND STORAGE

When transporting and storing your model, you will need a minimum of 70 inches (1.8m) in length, and 28 inches (54cm) in height to accommodate the size of the fuselage. We also recommend the use of wing and stabilizer bags to help protect these surfaces during transport and storage. The control horns and linkages can cause damage to other surfaces even when placed in storage bags. Always transport and store the wings and stabilizer so the linkages do not contact other panels to prevent damage.

When building the aircraft, you will be required to thread machine screws into blind nuts. We recommend pre-threading the screws to make sure the blind nuts are clear of any debris. If the screws do not thread in easily, clear the threads using the appropriate tap and tap handle. NOSE WEIGHT This model will likely require the addition of nose weight to properly balance. Testing has been performed on all power options. Using a heavier engine or motor will help in reducing the amount of weight required. Make sure to use proper throttle management when fl ying with these larger and more powerful options. Our test aircraft with the recommended Evolution® 62cc engine and muffl er, and receiver and ignition batteries under the fuel tank. Using engines other than those recommended may require the additional weight to properly balance. This may vary from plane to plane. Add this weight as far forward in the fuselage as possible to reduce the amount required to balance. This weight must be secure so it does not come loose in fl ight, causing an unsafe model which could result in the loss of the aircraft.

FOR THE VISUALLY CHALLENGED

A copy of this manual can be found at www.horizonhobby.com under the tab for this particular model. Feel free to download this manual and use a PDF viewer to zoom in on any text or images that may be in question when building from the printed manual.4. Use a hobby knife and #11 blade to remove the covering from the retract openings in the wing. Trim the covering inside the opening.

5. Use low-tack tape to secure a piece of cardboard over the wing. This

will provide a place to rest the retract when routing the air lines and prevent damage to the underside of the wing.

7. Cut a 19-inch (482mm) piece of the orange and blue air line. Attach

each air line to the retract. Using different colors makes connecting the retracts correctly much easier when assembling the model. Use a heat gun on low to soften the air lines slightly so they will slide on the fittings. Make sure to orient the air line colors the same on both the left and right retracts so they operate in the same manner.

8. Route the air lines into the wing.

6. Use a pin vise and 1/8-inch (3mm) drill bit to make a hole in the

retract well for the air line.

9. Both air lines can be retrieved at the fl ap servo opening. Use a piece

of low-tack tape to secure the lines together so they don’t fall back into the wing.

10. Fit the retract in the wing. Trim as necessary to provide clearance.

12. Place a lock washer on the M4 x 25 button head cap screw. Prepare

four screws at this time.

13. Use the M4 x 25 button head cap screws to secure the retract in the

wing. Place a drop of threadlock on each of the screws before their installation. Tighten the screws using a 2.5mm hex wrench. The cardboard can be removed from the wing after the retract has been secured. It may be necessary to use spacers under the retract frame to make sure there is no torsional stress when tightened into position. Torsional stress can cause intermittent operation of the retract unit.

11. The air lines can now be retrieved at the wing root.

6EN14. Place a drop of light machine oil on the M6 x 55 socket head cap screw that will function as the wheel axle.

15. Slide the M6 x 55 socket head cap screw through the wheel. Make

sure the wheel spins freely on the screw.

17. Position the gear door mount near the wheel as close to the wheel

as possible. The fl at area will align with the bottom of the wing. Use an M3 x 5 setscrew and 1.5mm hex wrench to secure the position of the gear door mount. Do not over tighten the screws or use threadlock as it will damage the composite material of the mounts.

inches (70mm) from the lower mount.

16. Thread the screw into the retract. Tighten the screw enough that the

wheel can spin freely, yet there isn’t any excess movement of the wheel on the screw. Once set, use an M3 x 5 setscrew and 2mm hex wrench to tighten the setscrew. Use a drop of threadlock on both the M6 x 55 socket head cap screw and M3 x 5 setscrew to prevent them from vibrating loose.

19. Use an M3 x 5 setscrew and 1.5mm hex wrench to secure the

position of the gear door mount. Do not over tighten the screws or use threadlock as it will damage the composite material of the mounts.

20. Tape a piece of paper to the wing that will go over the upper mount.

Rub a pencil on the paper to reveal the locations for the mounting holes.

22. Attach the gear door to the mount using two M3 x 12 button head

screws and a 2mm hex wrench. Check the positioning of the door to make sure it is centered in the opening and aligns with the opening near the wheel. Do not over tighten the screws or use threadlock as it will damage the composite material of the mounts.

23. Use a felt-tipped pen to mark the location for the upper gear door

mounting screws on the gear door.

21. Use a drill and 1/8-inch (3mm) drill bit to drill the holes for the lower

gear mounting holes in the gear door. 7 EN Ki-43 Oscar 60cc ARF24. Remove the cover and use a drill and 1/8-inch (3mm) drill bit to drill the two holes for the upper gear door mounting screws. The door can now be attached to the mounts using the four M3 x 12 button head screws and 2mm hex wrench.

25. If the gear door is not fl ush with the bottom of the wing, the mounts

may need to be adjusted. The mounting area for the lower mount can also be sanded using medium grit sandpaper to make any adjustments to the gear door alignment.

27. Place the cover into position. Use a felt-tipped pen to mark the

locations for the mounting screws

28. Use a pin vise and 1/16-inch (1.5mm) drill bit to drill the mounts for

26. Use a hobby knife or other sharp tool to puncture the covering at the

screw holes that will secure the cover to the wing. Also remove the covering to clear the retract mechanism.

29. Thread an M2 x 10 sheet metal screw into each hole using a #1

Phillips screwdriver. Remove the screws before proceeding.

30. Apply a small amount of thin CA to harden the threads made in the

previous step. Allow the CA to fully cure before installing the retract cover.

31. Secure the retract cover to the wing using four M2 x 10 sheet metal

screws. Use a #1 Phillips screwdriver to tighten the screws.

32. Check that the retract can be fully extended without the gear door

hitting the cover. Trim the gear door as necessary if it hits the cover. There will be movement in the gear during their operation so make sure there is a gap between the gear door and wing so they do not contact each other during the operation of the gear.

33. Use hobby scissors and medium grit sandpaper to prepare the hub

caps for installation. The hub caps can be painted if desired. Be sure to fully scuff and prepare the surface. Applying paint directly to the hub cap with no preparation will result in flaking paint. Always test paint on a piece of scrap material to check its compatibility to the plastic. 8EN34. Use contact adhesive to glue the hub cap to the wheel. Use low-tack tape to hold the hub cap in position until the adhesive fully cures. Repeat this section to install the remaining retract assembly. AILERON INSTALLATION

1. Use medium-grit sandpaper to lightly sand the control horn where

it fi ts into the control surface. Clean the sanded area using a paper towel and isopropyl alcohol to remove any debris or oils. This provides the surface texture necessary for the epoxy to bond to. Use tape on the painted area to help prevent removing the exposed portion of the control horn. Remove the tape once the control horn has been sanded.

2. Insert the M3 x 10 button head screw into the hole in the control

horn. Remove any paint using a hobby knife and #11 blade so the screw fi ts into the hole easily. Check all the control horns. The hole should be just large enough for the screw to slide through, yet still fit snugly in the hole and not move excessively.

4. Test fi t the control horn in the slot. Do not force the control horn into

the slot. Use a square to make sure the control horn is square to the control surface. Do not force the control horn in the slot. If the control horn fits tight, or is not square, use a rotary tool 3/32-inch (2.5mm) drill bit to carefully enlarge and reshape the hole. Wrap a piece of low-tack tape around the drill bit to set the depth of the drill bit so it won’t accidentally pass through the opposite side of the control surface.

3. Run your fi nger along the bottom of the aileron to locate the area

for the control horn. Use a hobby knife and #11 blade to remove the covering, exposing the slots for the control horn. 9 EN Ki-43 Oscar 60cc ARF5. Place tape around the slot in the aileron for the aileron control horn.

6. Remove the control horns from the control surfaces. Apply epoxy to

the slot in the aileron. Make sure the epoxy gets into the slot for a good bond between the surfaces and control horn.

8. Before the epoxy fully cures, remove the tape from around the

control horn. This will allow the epoxy to fl ow around the control horn, creating a small fi llet between the control horn and surface for a fi nished look and secure bond. Allow the epoxy to fully cure before proceeding.

9. Test fi t the remaining control horn. When gluing the control horn,

place the ball end between the horns and insert the M3 x 10 button head screw through the control horns and rod ends. This will align the horns correctly, making the linkage installation easier later.

7. Apply epoxy to the area of the control horn that fi ts into the slot. Use

enough epoxy so the control horn will be fully bonded to the control surfaces.

10. Once the epoxy has fully cured, pull on the control horn to make

sure it is glued securely in the aileron. If not, remove the control horn and sand off any adhesives. Repeat this section to glue the control horn in the aileron.

10ENHINGING THE AILERONS

Do not mix any epoxy until instructed to do so. Use the short hinges for the ailerons. The longer hinges are used for the flaps due to the hinging technique used.

1. Apply a small amount of oil to the fl ex point of the hinge to prevent

epoxy from entering the hinge.

2. Insert the hinge so the center of the hinge point aligns with the front

edge of the bevel on the control surface. Check that the hinge can move freely.

3. Position the hinge so it is perpendicular to the hinge line when fully

6. Insert the hinges into the control surface. Verify the hinge position

is correct. Use a paper towel and isopropyl alcohol to remove any excess epoxy. Allow the epoxy to fully cure before proceeding.

7. Mix 1/2 ounces (15mL) of 30-minute epoxy. Use a toothpick to apply

epoxy inside each of the holes for the hinges.

4. Mix 1/2 ounces (15mL) of 30-minute epoxy. Remove the hinges,

then use a toothpick to apply epoxy inside each of the holes for the hinges.

5. Apply epoxy to the outside of the hinge using a toothpick

9. Fit the aileron to the wing. Check that the aileron can move freely,

and the hinges are all aligned properly.

8. Apply epoxy to the outside of the hinge using a toothpick

10. Use a paper towel and isopropyl alcohol to remove any excess

epoxy. Use low-tack tape to hold the aileron in position until the epoxy fully cures. 11 EN Ki-43 Oscar 60cc ARF11. Once the epoxy has fully cured, pull on the wing and aileron to make sure the hinges are glued securely. If not, remove the aileron and sand off any adhesives. Repeat this section to glue the hinges.

AILERON SERVO INSTALLATION

1. Use a hobby knife and #11 blade to remove the covering for the

inches (80mm). 12EN 5/8 inch (16mm)6. Secure the servo ball link to the servo arm using an M3 x 10 button head screw, M3 washer and M3 lock nut. Use a 2.5mm hex wrench and 5.5mm nut driver to tighten the hardware.

11. Secure the servo ball link to the control horn using an M3 x 10

button head screw, M3 washer and M3 lock nut. Use a 2.5mm hex wrench and 5.5mm nut driver to tighten the hardware. Connect the servo to the radio system to hold the aileron servo in the centered position. Disconnect the ball from the control horn and adjust the linkage so the aileron is in the neutral position. Reinstall the hardware once the linkage has been adjusted.

12. Use the steps outlined for the retract cover to install the aileron

7. Secure a 6-inch (150mm) servo extension to the servo using a

commercially available retainer (SPMA3054). The length of the extension may vary depending on servo selection. The extension listed works with the recommended servos.

8. Tie or tape the string located inside the wing to the end of the servo

9. Use the string to pull the servo lead through the wing and out at the

root. We left a small amount of the string on the aileron servo lead so it can be quickly differentiated between the flap servo lead that will be installed later.

10. Install the aileron servo in the wing with the output facing the

leading edge. Make sure to prepare the servo mounting holes by threading a servo mounting screw into each hole and removing them. Harden the mounting screw locations with thin CA before installing the servo. 13 EN Ki-43 Oscar 60cc ARFHINGING THE FLAPS The flaps must be positioned to the wing before the epoxy begins to cure. Make sure to read through all the steps before mixing any epoxy. Glue only one flap at a time to allow enough working time to properly install the hinges.

1. Locate the fl ap control horns. When installed, the concave portion of

the horn (as indicated in the drawing) will face toward the top of the fl aps.

6. The fl ap will also align to the bottom of the wing when the hinges

are positioned correctly.

8. Apply epoxy to each hinge where it will be inserted into the fl ap.

Insert the hinges in the fl ap. Use 15-minute or 30-minute epoxy to allow enough working time during the hinge installation.

7. Remove the fl ap from the wing and remove the hinges. Apply epoxy

into each of the holes in the fl ap. Do not use an excessive amount of epoxy when gluing the hinges. Use enough epoxy to securely adhere the hinges to the surfaces.

2. Run your fi nger down the leading edge of the fl ap to locate the

area for the fl ap control horns. Use a hobby knife and #11 blade to remove the covering, exposing the slots for the control horn. Use 15-minute epoxy to glue the fl ap control horns in position. Remove any excess epoxy using a paper towel and isopropyl alcohol. Use the steps outlined for the aileron control horns to install the flap control horns. Make sure to check that the flap control horns are glued securely in the flaps once the adhesive fully cures.

9. Apply epoxy to each hinge where it will be inserted into the wing.

10. Apply epoxy into each of the holes in the wing.

3. Wrap a piece of low-tack tape around the fl ap to create a tab so the

fl ap can be lifted and lowered into position when fi tting the hinges. Use the long hinges when installing the flaps to the wing.

4. Test fi t the hinges to the fl ap. Do not use any adhesives now. Slide

the hinge into position. Position as shown, checking to make sure it can move freely.

5. Check the fi t of the fl ap to the wing. It will fi t centered in the

opening. The hinge pin will be positioned directly over the gap between the leading edge of the fl ap and the aft edge of the wing opening. Test the operation of the fl ap to make sure the hinges are properly aligned and the fl ap movies freely. 14EN11. Fit the fl ap to the wing. Check that the fl ap can move freely, and the hinges are all aligned properly. Use low-tack tape to hold the fl ap in position until the epoxy fully cures.

12. Use a paper towel and isopropyl alcohol to remove any excess epoxy

before it can fully cure. Use care not to get epoxy in the moving part of the hinge or between the fl ap and wing. Continue once the epoxy has fully cured for both sets of fl ap hinges. Make sure to check that the flap hinges are glued securely once the adhesive has fully cured. Repeat this section for the remaining flap hinge installation.

perpendicular to the servo centerline. We recommend setting the throws to 0% for radios using a three-position switch to prevent damaging the servo if the linkage is not the correct length.

2. When attaching the linkage to the aileron servo arm, use the hole in

the arm that is 5/8-inch (16mm) from the center of the arm.

4. Assemble the linkage for the fl ap using two ball ends and the 4

inch (120mm) threaded rod. Thread each ball end 12 turns on the link. Adjust the length so the distance between the ball ends measures 4

3. Prepare both the left and right fl ap servos at this time.

15 EN Ki-43 Oscar 60cc ARF 5/8 inch (16mm)6. The ball link will be attached to the underside of the servo arm as shown.

11. Move the servo to the UP fl ap position using the radio system. Adjust

the throws at the radio system to bring the fl ap in alignment with the bottom of the wing.

12. Move the servo to the FULL fl ap position of

50–60mm) using the radio system. Adjust the throws in the radio system to obtain the measurements listed.

13. The linkage may rub against the wing structure depending on servo

selection. Use a hobby knife with a #11 blade or a rotary tool and sanding drum to trim the wing structure as necessary to clear the linkage.

7. Install the fl ap servo in the wing with the output facing the leading

edge. Make sure to prepare the servo mounting holes by threading a servo mounting screw into each hole and removing them. Harden the mounting screw locations with thin CA before installing the servo. The flap servos can be positioned in the wing to allow the use of a Y-harness to connect the servos to the receiver.

8. Secure the servo ball link to the control horn using an M3 x 10

DROP TANK INSTALLATION

1. Run your fi nger along the bottom of the wing to locate the blind nuts

for the drop tank mount. Use a hobby knife and #11 blade to remove the covering, exposing the blind nuts. Thread a screw into the blind nuts by hand first to make sure the threads are clear. Cross threading, stripping, or damaging the blind nuts withing the wing will require considerable work to rectify.

2. Thread the drop tank mounts into the blind nuts in the pylons. Do not

over-tighten the mounts and damage the pylon.

3. Attach the pylon to the wing using two M4 x 15 socket head cap

screws and two M4 lock washers. Use a 3mm hex wrench to tighten the screws. Place a drop of canopy glue on each screw before their installation. This will keep them from vibrating loose yet leave them easily removable.

4. Attach the drop tank to the mounts using four M3 x 12 button head

screws. Use a 2mm hex wrench to tighten the screws. Place a drop of canopy glue on each screw before their installation. This will keep them from vibrating loose yet leave them easily removable.

for the stabilizer. Use a hobby knife and #11 blade to remove the covering from the fuselage.

6. Use a razor saw to remove the section of the tail post from the

stabilizer slot. The tail post is left in position at the factory to prevent damage and maintain the structural integrity of the fuselage during shipping and must be removed to install the stabilizer.

7. Use medium grit sandpaper to sand the fuselage smooth with the

3. Separate the elevators from the stabilizer. 8. Run your fi nger along the top of the wing to locate the blind nut

for the wing retaining bolt. Use a hobby knife with a #11 blade to remove the covering from the wing to expose the blind nut for the wing retaining bolt. For additional security, glue can be applied to the blind nut on the inside of the wing. Epoxy with micro balloons to thicken it works well for this task. Make sure not to get any adhesive inside the threads of the blind nut.

9. Slide the wing tube into the wing tube socket.

The wing tube may be a tight fit in the socket. Polishing the wing tube with fine sand paper or steel wool will help ease the installation of the wing tube. Do not force the wing tube in the socket as it can damage the structure inside the wing.

4. Run your fi nger along the bottom of the stabilizer to locate the

center. Use a hobby knife and #11 blade to remove the covering from the center section. 18EN10. Slide the wing panel into position. Guide the fl ap and aileron leads, as well as the retract air lines, into the fuselage.

bolt. Repeat the steps to secure the remaining wing panel on the fuselage.

15. Use a felt-tipped pen to transfer the fuselage outline onto the top of

16. Use a ruler and a hobby knife with a #11 blade to carefully cut the

covering 1/8 inch (3 mm) inside the line drawn on the top of the stabilizer to remove the covering from the center of the stabilizer. Use care not to cut into the underlying wood, weakening the stabilizer.

18. Use an epoxy brush to apply epoxy to the exposed wood on the

bottom of the stabilizer as well.

17. Mix 3/4 ounce (25ml) of 30-minute epoxy. Use an epoxy brush to

apply epoxy to the exposed wood on the top of the stabilizer.

12. Place the stabilizer in position. Use a straight edge to align the rear

of the stabilizer and fi n.

13. Stand back 8-10 feet (2-3 meters) and check that the stabilizer

is aligned with the wing. Lightly sand the stabilizer saddle on the fuselage to correct any misalignment.

14. Measure from each wing tip to each stabilizer tip. Adjust the

stabilizer so the measurements are the same for both sides.

19. Use an epoxy brush to apply epoxy to the stabilizer mounting surface

for the stabilizer. Position the stabilizer back on the fuselage and check its alignment. Use a paper towel and a small amount of isopropyl alcohol to remove any excess epoxy from the fuselage and stabilizer before the epoxy fully cures. Allow the epoxy to fully cure before proceeding. Check the position of the stabilizer repeatedly during the curing process to make sure it has not moved. 19 EN Ki-43 Oscar 60cc ARF A=A

1. Install the elevator control horns. Their installation is the same as the

aileron control horns. Make sure to check that the control horns are securely glued before proceeding.

2. Glue the hinges in the elevator using 30-minute epoxy. The

installation of the elevator hinges is similar to the aileron hinges. Use the short hinges to hinge the elevators

3. Glue the hinges to the stabilizer using 30-minute epoxy.

Make sure to check that the elevator hinges are glued securely once the adhesive has fully cured.

6. Use a hobby knife with a #11 blade to trim the covering so the

9. Place a drop of threadlock on each of the screws. Secure the tail

wheel bracket in the fuselage using the screws from the previous step and a 2.5mm hex wrench.

10. Slide the cables into the tubes in the fuselage. Retrieve the cables

inside the fuselage. 23 EN Ki-43 Oscar 60cc ARF15. Glue the tail wheel fairing to the tail wheel cover using contact adhesive. Make sure not to glue the cover to the fuselage in case the cover requires removal to access the tail gear.

2. Carefully remove the lower instrument panel using a hobby knife

3. Use contact adhesive to glue the pilot in the cockpit. Allow the

adhesive to fully cure before proceeding.

PILOT AND CANOPY INSTALLATION

1. When fi tting the pilot in the cockpit, the lower portion of the

instrument panel must be removed. Production models may not need the lower portion of the instrument panel removed.

4. Glue the head rest in position using medium CA or contact adhesive.

5. Glue the control stick in the cockpit using medium CA or 5-minute

epoxy. Position the control stick near the hands of the pilot when a pilot has been installed. 24EN6. It may be necessary to trim excess material from the canopy. Use hobby scissors to trim the canopy, then use medium grit sandpaper to smooth the edges.

ELECTRIC MOTOR INSTALLATION

As with many scale warbirds, the Ki-43 Oscar has a short nose moment. It maybe necessary to add nose weight depending on what power system is used. Be aware of this when assembling and try to keep all components as far forward in the fuselage as possible.

7. Use medium-grit sandpaper to lightly sand the inside edge of the

canopy where it contacts the canopy hatch. Clean the sanded area using a paper towel and isopropyl alcohol to remove any debris or oils. This provides the surface texture necessary for the adhesive to bond to.

1. Place the mounting template on the fi rewall. Use low-tack tape to

hold the template in position. Use a drill and 1/4-inch (6mm) drill bit to drill the four holes in the fi rewall to attach the motor. When using power systems other than the recommended choices, we advise using the mounting template as a test to ensure hole alignment before drilling the firewall.

8. Use canopy glue or contact adhesive to glue the canopy to the

canopy hatch. Use tape to hold the canopy in position until the adhesive fully cures. Do not use CA when gluing the canopy. When CA cures, it releases gases that can fog the canopy and detract from its appearance.

2. Use the screws and standoffs to draw the blind nuts into the fi rewall

from inside the fuselage.

3. Solder any connectors necessary to connect the speed control to

the motor and battery. Secure the speed control to the fi rewall using screws or tie wraps.

interfere with the operation of the throttle servo.

17. Use 15-minute epoxy to glue the pushrod tube support to the rear

edge of the inner fuselage side.

12. Prepare the holes in the fuselage for the throttle servo by threading

a screw into each hole. Remove the screws and place 2 to 3 drops of thin CA in each hole to harden the surrounding wood. Once the CA has fully cured, install the throttle servo with the servo shaft toward the rear of the fuselage.

13. Mount the throttle servo connector in the throttle servo arm so it is

7/16-inch (11mm) from the center of the servo arm. Place a drop of canopy glue on the M2 nut, then install it on the underside of the arm to secure the connector.

28ENFUEL TANK INSTALLATION

1. Cut a piece of fuel tubing that will result in the end of the clunk

inches (143mm) from the back of the aluminum plate.

6. Secure the fuel tank to the fuel tank tray using hook and loop straps

inch ((190mm) pieces of fuel line to the three lines exiting the tank. Use tie wraps to prevent the lines from sliding loose.

2. Secure the tubing to the clunk and stopper using thin wire. This will

keep the tubing from sliding loose inside the tank. Make sure to use the clunk supplied with your engine. A second clunk can be installed to provide a line to fuel/de-fuel your aircraft. We recommend using a clunk with a filter for all engine installations.

7. Prepare and harden the holes in the fuselage for the fuel tank tray

screws using an M3 x 15 sheet metal screw and thin CA. Secure the fuel tank tray in the fuselage using four M3 x 15 sheet metal screws and four M3 washers.

3. Insert the clunks into the tank. Install the larger clunk, then the small

clunk. The vent line will angle toward the top of the fuel tank.

8. Pass the fi ll line through the fi tting in the fuselage. Insert the fi ll plug

in the fi ll line from the tank.

4. Mark the lines from the tank so the fuel lines can be identifi ed from

outside the tank. Tighten the screw in the stopper using a #1 Phillips screwdriver. Check that both clunks can move freely inside the tank. If not, adjust the tubing from outside the tank so they can move freely to ensure consistent fuel flow to the engine.

9. Press the plug into the fi tting to secure the fi ll line. Route the vent

line from the tank to the bottom of the fuselage. Use a fi tting at the underneath the fuselage to secure the vent line.

10. Connect the line from the fi ltered clunk to the carburetor. Use a tie

wrap to secure the line to the carburetor. Use a filter between the fuel tank and carburetor to avoid the potential of debris that could be in the fuel from entering the carburetor and engine.

5. Use a hobby knife with a #11 blade to remove the covering from the

fuselage for the fi ll line fi tting. Install the fi tting in the fuselage. The fill line can also be left inside the fuselage to retain the scale look of the model. The removal of the canopy hatch will be required to add fuel to the fuel tank. 29 EN Ki-43 Oscar 60cc ARF11. Mount the ignition module to the fi rewall. Use the instructions provided with the engine to connect the module to the engine and ignition battery.

RETRACT AIR SYSTEM INSTALLATION

1. Cut a 12-inch (305mm) piece of air line and attach it to the air tank.

Use a heat gun on low to soften the air lines slightly so they will slide on the fittings.

2. Remove the servo arm from the rudder servo. Place straps around

the tank in the fuselage.

3. Apply a small amount of contact adhesive on the tray. Use the straps

to secure the air tank in the fuselage.

4. Route the air line under the servo tray to the location for the air

5. Cut two 4 inch (102mm) pieces of orange air line and one 4 inch

(102mm) piece of blue air line. Attach the orange air lines to the fi tting near the end and center fi ttings of the air valve, and the blue air line to the fi tting near the actuator. Do not remove the actuator from the valve body as it will damage the O-rings and cause an air leak in the valve. Use a heat gun on low to soften the air lines slightly so they will slide on the fittings. 30EN6. Secure the air valve in the fuselage. Use a 14mm wrench to tighten the nut, securing the valve in place.

7. Prepare the holes in the fuselage for the retract valve servo by

threading a screw into each hole. Remove the screws and place 2 to 3 drops of thin CA in each hole to harden the surrounding wood. Once the CA has fully cured, install the retract valve servo with the servo shaft toward the rear of the fuselage.

11. Toggle the switch at the radio and slowly increase the throw until

the edge of the actuator is fl ush with the edge of the valve body. Make sure not to pull the actuator out of the valve body and damage the O-rings.

9. Mount the servo connector in the servo arm so it is 11/32-inch

(9mm) from the center of the servo arm. Place a drop of canopy glue on the M2 nut, then install it on the underside of the arm to secure the connector. Set the throws for the retract servo to 0% in both directions. Center the actuator as close to center as possible, then tighten the setscrew securing the pushrod in the connector.

13. Cut a 2-inch (51mm) piece of air line and connect the fi ll valve. The

arrow will point to the fi tting/valve. Attach the line from the air tank to the fi tting. The arrow indicates the flow of air from the external fill pump into the retract system. There is a check valve inside the valve that stops air from flowing the other way and emptying the air tank.

14. Connect the remaining Y fi ttings for the up and down air lines. Use

air line colors that match those from the valve to differentiate the operation of the retracts. Route the air lines in the fuselage along the edges of the radio tray toward the openings for the wing. Secure all the air lines and fi ttings in the fuselage. Add fi ttings at the ends of the air lines to connect the air lines from the retracts in the wing panels. With the push-in type pneumatic connectors it is important to make sure the air line is pushed all the way into the air connectors to seal the air lines. Failure to do so will result in air leaks.

8. Insert the Z-bend of the retract valve pushrod through the hole in the

12. Connect a Y fi tting to the tube from the center of the valve. Fully

press the air line into the fi tting. The air lines can be removed by pressing the shoulder against the body of the fitting and pulling the air lines free. It does not require much throw to operate the valve. Make sure not to damage the valve using too much throw at the servo.

10. Slowly increase the servo throw at the radio system to move the

actuator into the valve. Make sure not to bottom out the actuator and damage the valve. 31 EN Ki-43 Oscar 60cc ARFRECEIVER INSTALLATION

1. Install the receiver in the fuselage. Secure the receiver using the

methods included in the receiver or radio instructions.

COWLING AND SPINNER INSTALLATION

The spinner cone has been prepared with the slots for the propeller. Most engines of this size use four bolts to retain the propeller. Careful positioning of the drilled holes is required to make sure the propeller aligns with the cutouts in the spinner cone. We recommend preparing at least two propellers in case a new propeller is required when out flying the model.

2. Mount any remote receivers in the fuselage using hook and loop

tape. Use the instructions provided with the receiver to orient the remote receivers in the fuselage for the optimum operation of the receiver. Apply a small amount of 5-minute epoxy to the hook and loop tape to secure them in the fuselage.

1. Place the washer from the engine on the spinner backplate. Mark

the locations for the propeller mounting screws using a felt-tipped pen.

3. Use a stepped reamer or bolt through the spinner back plate and

propeller to hold them in alignment so the bolt holes for attaching the propeller can be marked.

4. Use the four M3 x 10 socket head cap screws to secure the spinner

cone to the back plate. Use a 3mm hex wrench to tighten the screws. Position the propeller so it does not contact the spinner cone. Use a pin vise and 3/16-inch (4.5mm) drill bit to drill and indent or marker for the mounting bolt locations. It may be necessary to trim the spinner cone to clear the propeller depending on the choice of propellers.

2. Remove the washer from the backplate. Use a drill and 7/32-inch

(5mm) drill bit to drill the holes for the propeller mounting screws. A drill press is highly recommended for drilling the holes to guarantee the holes are properly aligned when installing the propeller. 32EN5. Disassemble the spinner and remove the propeller. Use a drill and 7/32-inch (5mm) drill bit to drill the holes in the propeller for the mounting screws. A drill press is highly recommended for drilling the holes to guarantee the holes are properly aligned when installing the propeller.

10. Place a piece of clear plastic between the cowl mounts and the cowl

ring. Secure the cowl mounts to the fuselage using the M4 x 15 socket head cap screws, M4 lock washer and M4 washer. Align the mount with the cowl ring and tighten the hardware using a 3mm hex wrench.

6. Remove the material in the center of the dummy radial for the

propeller shaft and drive washer for your particular motor. The dummy engine is supplied unpainted. It is functional as an air baffle which helps direct air over the gas engines cylinder head. Failure to fit the dummy engine may result in your gas engine overheating due to poor airflow through the cowling vents.

11. Slide the cowling into position. Center the drive washer in the

7. The top of the radial engine is indicated by two indentations that will

align with the gun exits in the cowling. Use this as a reference when trimming the engine.

12. Attach the propeller to the motor shaft using the hardware included

with the engine. Position the cowling so the propeller is equal distance from the cowling when rotated.

8. Gas: Trim the dummy radial engine to allow air to pass over the

engine and to clear the carburetor if necessary. EP: Trim the material between the cylinders of the dummy radial engine to allow cooling air to pass across the motor and ESC. The photo shows the radial engine prepared for the gas engine installation.

13. Use thin CA to tack glue the mounts to the cowling.

The mounts will be removed to be glued securely in the following steps. Do not use excessive amounts of glue in this step. The dummy radial engine can be detailed using paint before securing it in the cowling. Make sure to test any paints on the trimmed pieces to make sure they are compatible with the plastic.

9. Use sandpaper to remove the paint from the dummy radial where

it contacts the inside of the cowling. This will increase the bond of the adhesive to the dummy radial. Use 15-minute epoxy to glue the radial engine inside the cowling. Allow the epoxy to fully cure before proceeding.

14. Carefully remove the screws and cowling from the fuselage. Use a

felt-tipped pen to trace the outline of the mounts on the inside of the cowling. 33 EN Ki-43 Oscar 60cc ARF15. Remove the mounts and use medium grit sandpaper to sand the area inside the cowling where the mounts rest, and an area at least 1/2 inch (13mm) outside of the area marked. Use a paper towel and isopropyl alcohol to remove any oils or debris from the inside of the cowling. Preparation for gluing the mounts is important to guarantee the adhesive can properly bond the mounts to the inside of the cowling.

16. Mix 1/2 ounce (15ml) of 30-minute epoxy. Apply epoxy inside the

cowling in the areas for the mounts.

17. Apply epoxy to the mounts using an epoxy brush.

18. Place the mounts in position in the cowling. Allow the epoxy to fully

cure before proceeding. Create a fillet extending out 1/2 inch (13mm) from the mounts to increase the bond between the mount and cowling.

19. Install the muffl er on the engine. Trim the cowling as necessary to

clear the muffl er or any other parts of the engine that may protrude outside the cowling. Mount the cowling back on the fuselage. Install the spinner backplate, propeller and spinner on the engine. 34EN

An important part of preparing the aircraft for fl ight is properly balancing the model. The Center of Gravity range supplied here is a guideline based on testing. Deviation from the measurements we provide is possible and may result in a model that suits your fl ying style better. Start with the recommended Center of Gravity, then feel free to experiment with different balance points. We advise adjusting progressively and cautiously.

1. Attach the wing panels to the fuselage. Make sure to connect the leads from the aileron and fl aps to the

appropriate leads from the receiver. Make sure the leads, as well as the air lines from the retracts, are not exposed outside the fuselage before tightening the wing bolts. Your model should be fl ight-ready before balancing.

2. The recommended Center of Gravity (CG) location for your model is 6 inches (152.5mm) behind the leading edge

of the wing. Take this measurement against the fuselage where the wheel well extends forward of the leading edge of the wing.

3. When balancing your model, make sure it is assembled and ready for fl ight. Support the plane inverted at the

marks made on the wing with your fi ngers or a commercially available balancing stand. The overall CG range for this model is 5

–7 inches (140–178mm). We recommend starting at the measurement listed above, then adjusting to suit your particular flying style. Nose weight may be required when using lighter weight engines. Move the batteries as far forward in the fuselage to help reduce the amount of weight required. CAUTION: You must adjust your aircraft’s center of gravity and balance your model properly before attempting fl ights. 6 inches (152.5mm)35 EN Ki-43 Oscar 60cc ARF CONTROL THROWS

1. Turn on the transmitter and receiver of your model. Check the movement of the rudder using the transmitter.

When the stick is moved to the right, the rudder should also move right. Reverse the direction of the servo at the transmitter if necessary.

2. Check the movement of the elevator with the radio system. Moving the elevator stick toward the bottom of the

transmitter will make the airplane elevator move up.

3. Check the movement of the ailerons with the radio system. Moving the aileron stick to the right will make the

right aileron move up and the left aileron move down.

4. Use a ruler to adjust the throw of the elevator, ailerons and rudder.

These are general guidelines for general sport and aerobatic fl ying from our own fl ight tests. You can experiment with higher or lower rates to match your preferred style of fl ying. Travel Adjust and Sub-Trims are not listed and should be adjusted according to each individual model and preference. Always install the control horns 90 degrees to the servo center line. Use sub-trim as a last resort to center the servos. Always re-bind the radio system once all the control throws are set to keep the servos from moving to their endpoints until the transmitter and receiver connect. PREFLIGHT CHECKLIST

• Charge the transmitter, receiver and motor batteries. Follow the instructions provided with the charger. Follow all manufacturer’s instructions for your electronic components.

• Check the radio installation and make sure all control surfaces (aileron, elevator, rudder, and fl aps) move correctly (i.e., the correct direction and with the recommended throws).

• Check all the hardware (control horns, servo horns, and clevises) to make sure they are secure and in good condition.

• Prior to each fl ying session (and especially with a new model), perform a range check of your radio system. See your radio manual for the recommended range and instructions for your particular radio system.

• Check the battery voltage of the transmitter battery. Do not fl y below the manufacturer’s recommended voltage. Doing so can cause your aircraft to crash.

• Check all hardware (linkages, screws, nuts, and bolts) prior to each day’s fl ight. Ensure that binding does not occur and that all parts are properly secured.

• Ensure all surfaces are moving in the proper manner.

• Perform a ground range check before each day’s fl ying session.

• All servo leads and switch harness plugs should be secured in the receiver.
