from the wing into the fuselage.

3. Check that the wing fi ts tightly against the fuselage.

4. Secure the wing panels to the fuselage using M3 x 12

socket head cap screws and M3 washers. Use a 2.5mm hex wrench to tighten the screws.. Use a drop of canopy glue on the screw to prevent it from vibrating loose.

2. Measure from the tip of the stabilizer to the wing. Position

the stabilizer so both measurements are equal. (Cowling has not been installed at this time.)

3. Check the alignment of the stabilizer to the wing. It

should be equal on both sides of the fuselage.

4. Check all alignments. Mark the outline of the fuselage on

the top and bottom of the stabilizer.

5. Use a ruler and carefully cut the covering 1/8 inch (3

mm) inside the line drawn on the stabilizer to remove the covering from the center of the stabilizer. Remove the top and bottom covering. Use care not to cut into the underlying wood, weakening the stabilizer.

1. Slide the stabilizer into the slot in the fuselage. Center the

7. Fit the joiner wire into the elevator halves.

6. Lightly sand the elevator joiner wire where it contacts

the elevators. Use a paper towel and isopropyl alcohol to remove any oil or debris from the joiner.

8. The elevator joiner wire must be fl ush with the leading

edge of the elevator as shown.

9. Check to make sure the elevator halves are in alignment

10. If the elevators are not in alignment, use pliers to bend

the joiner wire slightly to bring the halves into alignment. Î Poorly aligned elevators will cause problems with trimming your model in flight.

11. Continue the assembly of your model once joiner wire has

been correctly checked and adjusted.

12. Remove the elevators from the joiner wire. Fit the joiner

wire into the fuselage, noting the position from the previous step. This will guarantee the joiner is placed correctly so the elevators will be oriented as prepared in the previous step. Î The slot for the elevator horn will be located on the bottom right of the fuselage when the elevators are installed.

13. Slide the stabilizer partially into the fuselage so the

wood at the center is exposed. Mix 1/2 ounce (15ml) of 30-minute epoxy. Use an epoxy brush to apply the epoxy to the exposed wood on the top of the stabilizer.

14. Carefully turn the model over and apply epoxy to the

exposed wood on the bottom of the stabilizer. Slide the stabilizer back into position. Î Use care not to get epoxy on the elevator joiner wire.

15. Once the alignment of the stabilizer has been verifi ed, use

a paper towel and isopropyl alcohol to remove any excess epoxy from the fuselage and stabilizer. Allow the epoxy to fully cure before proceeding. Î If you find epoxy on the joiner wire, use the paper towel and isopropyl alcohol to clean the joiner.

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

hole in the center of each hinge slot to allow the CA to wick into the hinge. Drill holes in both the elevators and stabilizer surfaces at this time. Place a T-pin in the center of each hinge along side the slot in the hinge. This will help center the hinge when it is placed in the elevators. Slide the hinges into position with the T-pin resting against the edge of the control surface.

17. Fit the elevator into position on the stabilizer. Guide the

joiner wire and hinges into position.

19. Check the fi t of both elevators at this time. Once checked,

remove the elevators.

20. Use a small strip of the clear packaging material and

slide it between the joiner wire and stabilizer. Make sure the packing material is cut so it does not obstruct the hinge slot. Use a small piece of low-tack tape to hold the packing material in position. Î The clear packing material is used to prevent accidentally gluing the elevators or joiner wire to the stabilizer.

21. Mix a small amount of 15-minute epoxy. Use a toothpick

to apply epoxy to the joiner wire.

22. Use a toothpick to apply epoxy to the stabilizer where it

contacts the joiner wire.

18. Fit the elevator so the leading edge fi ts tightly against the

trailing edge of the stabilizer.

24. Check the alignment of the elevators in relationship to

the stabilizer at the tips. There should be enough gap between the balance tab and stabilizer to they can move freely. Î Do not use CA accelerator when gluing hinges. The CA must be allowed to soak into each hinge to provide the greatest bond between the hinges and surrounding wood.

25. Flex the elevator slightly, making sure to keep the gap

between the elevator and stabilizer as narrow as possible. Saturate each of the hinges using thin CA. Apply CA to the top of the hinges.

26. Flex the elevator slightly, making sure to keep the gap

between the elevator and stabilizer as narrow as possible. Saturate each of the hinges using thin CA. Apply CA to the bottom of the hinges. Allow the CA to cure before proceeding.

27. Gently pull on the fi xed and moving surface to make sure

the hinges are glued securely. If not, reapply thin CA to any hinges that are found loose.

23. Fit the elevators back into position. Remove the T-pins

and slide the elevators tightly against the stabilizer. Use a paper towel and isopropyl alcohol to remove any excess epoxy before it begins to cure.

28. Flex the control surface through its range of motion a few

times to break-in the hinges. This will reduce the initial load on the servo when the surface is fi rst actuated.

2. Check the fi t of the rudder to the fuselage. Make sure

the tail wheel wire fi ts into the rudder, and that the notch fi ts over the tail wheel bushing. There should be no gap between the fi n and rudder.

3. Once the epoxy fully cures, apply thin CA to both sides of

each hinge. Once the CA cures, gently pull on the fi xed surface and control surface to make sure the hinges are glued securely. If not, apply additional CA to secure each of the hinges.

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

hole in the center of each hinge slot. This allows the CA to wick into the hinge. Drill holes in both the rudder and fi n surfaces at this time. Place a T-pin in the center of the hinge. Slide the hinges into position with the T-pin resting against the edge of the control surface. RUDDER INSTALLATION

1. Position the steering tiller on the bottom of the rudder.

The arms of the tiller will be perpendicular to the rudder centerline. Make sure the tiller is as far forward as possible, yet doesn’t interfere with the operation of the rudder. Use a felt-tipped pen to mark the locations for the tiller mounting screws on the bottom of the rudder.

3. Use a #2 Phillips screwdriver to thread an M3 x 10 self-

tapping screw into each of the holes. Remove the screws, then apply a few drops of thin CA in each hole to harden the surrounding wood.

2. Use a pin vise and 5/64-inch (2mm) drill bit to drill

the two holes in the bottom of the rudder for the tiller mounting screws.

4. Secure the tiller arm on the bottom of the rudder using

two M3 x 10 self-tapping screws. Tighten the screws using a #2 Phillips screwdriver.

5. Before installing the tail wheel bracket, thread an M3 x 12

socket head screw into each blind nut. If the screw does not thread in easily, use a 3mm tap to clean the threads in the blind nut.

6. Place the tail gear bracing bracket in the notch in the

fuselage. Use two M3 x 20 socket head caps screws to secure the tail wheel bracket. Apply a small amount of threadlock on each screw and use a 2.5mm hex wrench to tighten the screws. Use threadlock on all metal-to- metal fasteners to prevent them from vibrating loose.

1. Use pliers to bend each of the fi ttings to about a

45-degree angle. Bias the bend toward the smaller hole in the fi tting.

2. Attach the fi ttings to the stabilizer using two M3 x 12

screws and two M3 nuts. Fittings are placed on the top and bottom of the stabilizer. Use threadlock on all the nuts to prevent them from vibrating loose.

3. Attach the fi ttings to the fi n using an M3 x 12 screws and

M3 nut. Fittings are placed on both sides of the rudder. Use threadlock on all the nuts to prevent them from vibrating loose.

7. Use side cutters to rim the excess wire from the springs.

Use small pliers to bend the last coil to form a loop that can be connected to the tail wheel arm and tiller arm.

4. Thread a cable end into the clevis. The threads of the

cable end will protrude 1/8-inch (3mm) between the forks of the clevis. Prepare four of these connectors. Use threadlock on all metal-to-metal fasteners to prevent them from vibrating loose.

5. Prepare one cable by sliding the cable through a sleeve,

through the cable end, then back through the sleeve.

8. Place the springs on the tiller arm and tail wheel steering

arm. It may be necessary to adjust the springs slightly so the tail wheel aligns with the rudder.

6. Pull the excess cable tight and use a crimping tool to

complete the job. Repeat for all four of the ends.

7. Attach the four connectors to the fi ttings on the top and

8. Repeat steps 5 and 6, only passing the cable through the

fi ttings instead of the cable ends. The cables should have very light tension. Make sure the rudder and stabilizer are square as illustrated in the stabilizer installation section of this manual.

2. Check the fi t of the elevator control horn. Make sure

the horn does not protrude through the top, deforming the covering. If so, lightly sand the horn so it is fl ush on the top when installed. Use 5-minute epoxy to glue the elevator horn in position. Use the technique outlined earlier when installing the horns.

3. Check the fi t of the rudder control horn. Make sure

the horn does not protrude through the opposite side, deforming the covering. If so, lightly sand the horn so it is fl ush on the opposite side when installed. Use 5-minute epoxy to glue the rudder horn in position. Use the technique outlined earlier when installing the horns.

Place the cowl back on the fuselage and secure it using the screws listed. Use a #1 Phillips screwdriver to tighten the screws. Important Information About Your Propeller Î Always ensure the propeller is balanced before installing it onto the shaft. An unbalanced propeller may cause poor flight characteristics. Î If it is necessary to enlarge the hole in the propeller, make sure to check the balance of the propeller afterwards.

3. Use a pin vise and 1/16-inch (1.5mm) drill bit to drill

four holes in the cowl using the paper templates as a guide. Make sure to drill into the 1/4-inch (6mm) wide sub-fi rewall.

2. Slide the cowling on the fuselage, making sure the

paper markers are on the outside of the cowl. With the spinner backplate and propeller attached to the motor shaft, position the cowl so there is a 3/32-inch (2mm) gap between the backplate and cowl. Also make sure the cowl is aligned with the backplate and trim scheme. Use low-tack tape to keep the cowl attached to the fuselage for the following steps.

6. Attach the spinner to the motor. Make sure the spinner

cutouts do not contact the propeller blades.

5. Attach the muffl er to the engine and connect any items

from the ignition module to their locations on the engine.

2. Connect the rudder and elevator servo leads to the

receiver. Connect an 18-inch (460mm) lead for the fl aps and ailerons to the receiver. Î Longer 24-inch (600mm) leads can be used for the ailerons and flaps and then routed underneath the cockpit floor for a clean installation of the radio system.

3. Mount the receiver and receiver battery in the fuselage

using hook and loop tape (not included). Route the servo leads neatly underneath the radio tray.

1. Use a hobby knife with a #11 blade to remove the

material from the aft edge of the receiver and battery cover. Drill two holes for the switch mounting screws using a 5/64-inch (2mm) drill bit. Mount the switch to the cover using the hardware included with the switch. Î Use the switch plate as a template when preparing the cover for the switch.

5. Holes can be made in the fl oor of the servo tray using

a hobby knife and #11 blade to route 24-inch (600mm) aileron and fl ap servo leads underneath the cockpit fl oor and up the inside of the formers.

4. Secure the remote receiver inside the fuselage using

hook and loop tape (not included). Make sure to orient the antenna on the remote receiver at a different angle than that of the main receiver for the best operation of your radio system.

7. Secure the receiver cover inside the fuselage using an

M3 x 12 socket head cap screw and M3 washer. When using the shorter fl ap and aileron extensions, a notch will need to be made in the cover to route the leads from the receiver to plug into the leads from the wing.

6. Use small tie wraps to secure the leads to the inside

edges of the formers so the windows can be installed in the next section of the manual.

2. Use canopy glue to glue the side and rear windows to the

inside of the fuselage. Use tape to hold the windows in position until the glue has fully cured.

1. Use a hobby knife to trim the bottom of the windows

that fi t into the door. Trim the bottom so there is 1/16- inch (1mm) of material below the edge of the fl at area below the window. The fl at area is where the window will contact the door frame, allowing you to glue it into position. WINDOW INSTALLATION

5. Use hobby scissors to carefully trim the ends from the

landing light lenses. Leave plenty of material so they can be glued to the wing surface.

4. Use 15-minute epoxy to glue the seats inside the

fuselage. Use scale references to correctly position the seats. Î If flying your model using an electric power system, use hook and loop tape to secure the front seat so it can be easily removed to change the motor battery.

3. Fit the front/top window into position. The top window

folds over the fuselage. Use canopy glue and low-tack tape to glue the windows into position. Î You can add scale details to the interior of your model before gluing the windows in position. There are numerous avenues for finding additional information as a guide to increase the scale appearance of your model available.

6. Trim the lenses as necessary so they fi t to the contour of

the wing. Use canopy glue to glue the lenses into position. A small amount of low-tack tape is used to hold the lenses in position until the glue fully cures.

2. Attach the strut bracket to the bottom the wing using two

M3 x 12 socket head cap screws for each bracket. Make sure to use threadlock on each of the screws to prevent them from vibrating loose.

1. Before installing the strut brackets, thread an M3 x 12

socket head screw into each blind nut. If the screw does not thread in easily, use a 3mm tap to clean the threads in the blind nut.

5. Thread the ends on the struts so there is roughly

1/8 inch (3mm) of thread exposed between the end of the strut and the fi tting. The exact position of the end will be adjusted when the struts are installed.

4. Thread the jury strut mounts into the holes in the wing.

The upper lip of the mount will be fl ush with the bottom of the wing.

3. Use a pin vise and 1/8-inch (3 mm) drill bit to remove any

excess paint from the hole in the jury strut mounts.

WING STRUT INSTALLATION

head cap screws and M3 locknuts.

8. Attach the jury struts to the jury strut mount using M3

x 12 socket head cap screws and M3 locknuts. Attach the spreader bar to the front and rear struts using M3 x 15 socket head cap screws and M3 locknuts. The strut bracket and spreader bar are inside the jury strut.

9. Check the positioning of the jury struts and hardware

using the photos 9 and 10.

10. Use a square to check that the jury struts are

perpendicular to the bottom of the wing. If not, the jury strut mounts on the struts can be repositioned to adjust the jury struts.

6. Measure the distance between the end of the strut and

the jury strut mount. The mounts are not centered on the strut: the side where the bracket is positioned 12

inches (317mm) from the end of the strut will be the side that attaches to the bracket.28EN

11. Position the wing back on the fuselage as outlined earlier

in this manual. Adjust the ends on the struts so the holes in the ends line up with the holes in the strut mounting tab. Slide the pin through the end and tab, then fi t a silicone tube on the pin. The pins are secured using the clips as shown in the photo.

12. Check the positioning of the pins and clips as shown in

photos 12 and 13. Î Use a hobby knife to trim the silicone tube into 1/8- inch (3mm) thick pieces so the clips are easier to install.

1. Apply the decals to your model using the photos located in this section of the manual and the box art from your

model. Use a spray bottle and a drop of dish washing liquid or glass cleaner sprayed in the location of the decal to allow repositioning of the decal. Use a paper towel as a squeegee to remove excess water from under the decal. Allow the model to rest overnight so the remaining water can evaporate. DECAL INSTALLATION CAUTION: You must adjust your aircraft’s center of gravity and balance your model properly before attempting fl ights.

An important part of preparing the aircraft for fl ight is properly balancing the model.

1. Attach the wing panels to the fuselage. Make sure to connect the leads from the aileron to the appropriate leads

from the receiver. Make sure the leads 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 3

inches (100–120mm) back from the leading edge at the center of the wing.

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

marks made on the wing with your fi ngers or a commercially available balancing stand. This is the correct balance point for your model.29 EN Carbon Cub 15cc 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 throw meter to adjust the throw of the elevator, ailerons and rudder.

inches (33mm) Flaps: Mid 7/8 inches (22mm) Landing Adjust the maximum throw without binding the servo or linkage. These are general guidelines measured from our own fl ight tests. You can experiment with different 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. We highly recommend re-binding the radio system once all of the control throws are set. This will keep the servos from moving to their endpoints until the transmitter and receiver connect.

• Charge the transmitter, receiver and motor battery for your airplane. Use the recommended charger supplied with your radio system. Follow the instructions provided with the radio. Charge the radio system the night before each fl ying session. Charge the transmitter and receiver batteries using only included or manufacturer-recommended chargers. Follow all manufacturer’s instructions for your electronic components.

• Check the radio installation and make sure all control surfaces (aileron, elevator, rudder and throttle) 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.

• Run the motor. With the model securely anchored, repeat the range check procedure. The range should not be signifi cantly affected. If it is, do not attempt to fl y! Remove the radio equipment and have it inspected by the manufacturer.
