INTRODUCTION

E-flite takes ARF ducted fan performance and engineering to new heights with the Habu 32 DF. Designed around the E-flite fan unit and 2150Kv DF32 brushless motor, its hyper-efficient intake and exhaust ducting allows this potent combo to produce large amounts of thrust when powered with an E-flite 6S 5000 30C Li-Po pack. And it does so without resorting to drag-inducing cheater holes. The result is a sport EDF with exhilarating speed that will give even experienced jet jockeys goose bumps.

As the first Platinum Series E-flite ducted fan, the Habu 32 DF also boasts a level of fit and finish that is every bit as impressive as its performance. Its sleek fiberglass fuselage comes pre-painted and integrates the vertical stabilizer. The fully-sheeted wings and horizontal stabilizers are mounted with carbon blade spars and covered with genuine UltraCote The control surfaces are hinged for you. Just add the optional E-flite electric retracts (sold separately), and you’ve got a sport jet that truly stands out from the crowd.

Required Tools and Adhesives

Felt-tipped pen 5-minute epoxy Mixing stick Mixing cup Low-tack tape Medium grit sandpaper

E-tips

We used low-tack tape to tape the aileron at the tip and to tape the ﬂap to the aileron so they don’t move during the control horn installation.

 1. Check the fit of the fiberglass control horn in the slot in the aileron. The hole in the control horn will align with the hinge line, and the horn will fit flush in the hole. Use a felt-tipped pen to mark the front and rear edge of the control horn on the aileron.

E-tips

During the course of building your model we suggest you use a soft base for the building surface. Such things as a foam stand, large piece of bedding foam or a thick bath towel will work well and help protect the model from damage during assembly. This is not shown in the instructions to provide the greatest detail in the photos.

When referencing directions (up, down, left, right top and bottom) these directions are in relationship to the pilot sitting in the cockpit of the aircraft unless noted otherwise.

 2. Apply low-tack tape around the opening for the flap and aileron control horn. Position the tape so it is 1/32-inch (1mm) away from the sides of the hole, as well as from the marks made in the previous step.

 3. Use medium grit sandpaper to lightly sand the control horns where they fit into the openings in the flap and aileron.

 4. Use 5-minute epoxy to glue the control horns into the holes for the flap and aileron. Use a square to make sure the control horn is perpendicular to the control surface. Also check again to make sure the hole in the control horn is directly over the hinge line.

 7. Sand a slight angle on the fiberglass control horn for the elevator. This is so the top of the horn does not distort the covering on the top of the elevator. Test fit the fiberglass control horn in the slot in the elevator, making sure the horn does not distort the covering on the top of the elevator.

 8. Repeat steps 1 through 5 to glue the control horns in both elevator halves.

 5. After around 3 minutes, before the epoxy cures, carefully remove the tape from around the control horns. Pull the tape away from the horn, being careful not to disturb the position of the control horn. This will allow the epoxy to flow out slightly, leaving a fillet between the control horn and control surface.

 6. Repeat Steps 1 through 5 to install the remaining aileron and flap control horn.

 9. Repeat steps 1 through 5 to glue the control horn in the rudder.

AILERON SERVO INSTALLATION

Required Parts

13mm x 10mm x 7mm (4)

Required Tools and Adhesives

Ruler Phillips screwdriver: #1 Scissors Hobby knife with #11 blade String Pencil Thin CA 5-minute epoxy Mixing cup Mixing stick Drill Drill bit: 5/64-inch (2mm) Rotary tool Sanding drum Medium grit sandpaper

2mm x 8mm self-tapping screw (8)

 2. Secure a 3-inch (76mm) servo extension to the aileron servo lead using string or a commercially available connector.

 3. Repeat steps 1 and 2 to prepare a second aileron servo. Note the servos will be mirror images of each other.

E-tips

Before starting the installation of the servos, we recommend centering the trims and sticks on your transmitter. If using a computer radio, make sure to reset a model memory and name it for this particular model. We also recommend binding the transmitter and receiver at this time following the instructions provided with your radio system.

 1. Prepare the aileron servo by installing the rubber grommets and brass eyelets as shown in the radio or servo instructions. Center the aileron servo using the radio system. Use side cutters to remove any arms from the horn that may interfere with the operation of the servo.

 4. Remove the cover from the wing for the flap and aileron servos. Set the cover aside for the flap servo at this time.

E-tips

The aileron linkage will be connected to the hole in the servo horn 3/8inch (10mm) from the center of the arm as illustrated in the photo above.

 5. Use a pencil to draw two lines on the cover. The first line is along the bottom of the cover, 3/32-inch (2.5mm) from the edge. The second line is 7/8-inch (22mm) from the side of the cover as shown. This will center the servo horn in the slot when using the recommended servos.

 6. Sand the 10mm x 7mm end of the block using medium grit sandpaper. This will be the end glued to the plate in the next step.

 8. Use a rotary tool and small sanding drum to make a notch in the block for the servo lead. Check the fit of the servo to make sure the servo lead can clear the mounting block.

 7. Use 5-minute epoxy to glue the 13mm x 10mm x 7mm hardwood block to the servo cover. Make sure to glue the 10mm x 7mm end to the surface of the plate. Allow the epoxy to fully cure before proceeding.

 9. Position the aileron servo with the grommets resting on the first mounting block and the servo parallel to the line on the cover. Use a pencil to mark the location for the remaining servo mounting block.

 10. Use 5-minute epoxy to glue the remaining block to the cover. Don’t forget to roughen the end of the block as shown in step 6.

 11. Position the servo between the two blocks. Leave a small gap between the servo and servo cover so vibrations from the airframe are not transferred directly into the servo. Use a pencil to mark the locations for the four servo mounting screws on the blocks.

 12. Use a drill and 5/64-inch (2mm) drill bit to drill the holes for the mounting screws. Use care not to enlarge the holes any larger than the drill bit.

 14. Use the screws provided with the servo and a #1 Phillips screwdriver to attach the servo to the mounting blocks.

 15. Apply 2–3 drops of thin CA in each of the aileron servo cover mounting holes. This will harden the surrounding wood, making the screws more secure when they are installed.

 13. Apply 2–3 drops of thin CA in each hole drilled. Also saturate the front and rear of the block using thin CA to harden the block. This will help keep the block from splitting when the servo mounting screws are installed.

E-tips

Do not use a CA accelerator. Using an accelerator will not allow the CA to soak into the ﬁbers of the wood, hardening the blocks.

 16. Tie the end of the string around the end of the aileron servo lead. Use the string to pull the aileron servo lead into the flap servo bay.

 17. Use four 2mm x 8mm self-tapping screws and a #1 Phillips screwdriver to secure the aileron servo cover to the wing.

 18. Use a hobby knife with a #11 blade to trim two 1/4-inch (6mm) pieces from the silicone tubing.

 20. Remove the tape holding the flap and aileron in position. Use the radio system to center the aileron servo. Connect the metal clevis to the inner hole of aileron servo horn. The remaining clevis connects to the aileron control horn. Adjust the length of the linkage so the aileron is centered when the servo is centered. Once the length of the linkage has been adjusted, slide the tubing over the forks of the clevises to keep them from accidentally opening in flight. Use needle nose pliers to tighten the nuts against the metal clevises.

 21. Repeat steps 4 through 20 to install the remaining aileron servo and linkage.

E-tips

Always use threadlock on metal-to-metal fasteners to prevent them from vibrating loose.

 19. Assemble the aileron linkage using the two pieces of tubing from the previous step, two 2mm nuts, two metal clevises and the 2mm x 25mm threaded rod. The length of the rod will be adjusted in the following steps.

 2. Repeat step 1 to prepare a second flap servo. Note the servos will be identical.

 3. Use a pencil to draw two lines on the cover. The first line is along the bottom of the cover, 3/32-inch (2.5mm) from the edge. The second line is 7/8-inch (22mm) from the side of the cover as shown. This will center the servo horn in the slot when using the recommended servos.

E-tips

When centering the ﬂap servo, begin by setting the throws at the transmitter to 0% for both the up and down ﬂap positions. This is done for both 2- and 3-position ﬂap switches.

 1. Prepare the flap servo by installing the rubber grommets and brass eyelets as shown in the radio or servo instructions. Center the flap servo using the radio system. Use side cutters to remove any arms from the horn that may interfere with the operation of the servo.

E-tips

The ﬂap linkage will be connected to the hole in the servo horn 1/2-inch (13mm) from the center of the arm as illustrated in the photo above.

 4. Sand the 10mm x 7mm end of the block using medium grit sandpaper. This will be the end glued to the plate in the following step.

 5. Use 5-minute epoxy to glue the 13mm x 10mm x 7mm hardwood block to the servo cover. Make sure to glue the 10mm x 7mm end to the surface of the plate. Allow the epoxy to fully cure before proceeding.

 8. Use 5-minute epoxy to glue the remaining block to the cover. Don’t forget to roughen the end of the block as shown in step 6.

 6. Use a rotary tool and small sanding drum to make a notch in the block for the servo lead. Check the fit of the servo to make sure the servo lead can clear the mounting block.

 9. Position the servo between the two blocks. Leave a small gap between the servo and servo cover so vibrations from the airframe are not transferred directly into the servo. Use a pencil to mark the locations for the four servo mounting screws on the blocks.

 10. Use a drill and 5/64-inch (2mm) drill bit to drill the holes for the mounting screws. Use care not to enlarge the holes any larger than the drill bit.

 7. Position the flap servo with the grommets resting on the first mounting block and the servo parallel to the line on the cover. Use a pencil to mark the location for the remaining servo mounting block.

 11. Apply 2–3 drops of thin CA in each hole drilled. Also saturate the front and rear of the block using thin CA to harden the block. This will help keep the block from splitting when the servo mounting screws are installed.

 13. Apply 2–3 drops of thin CA in each of the flap servo cover mounting holes. This will harden the surrounding wood, making the screws more secure when they are installed.

E-tips

Place a piece of low-tack tape on the ﬂap servo lead so it can be identiﬁed easily from the aileron servo lead.

 14. Tie the end of the string around the end of the flap and aileron servo leads. Use the string to pull the leads through the wing and out at the root rib as shown.

E-tips

Do not use a CA accelerator. Using an accelerator will not allow the CA to soak into the ﬁbers of the wood, hardening the blocks.

 12. Use the screws provided with the servo and a #1 Phillips screwdriver to attach the servo to the mounting blocks.

E-tips

Use low-tack tape to tape the ﬂap and aileron servo connectors together. This will make them easier to pull through the wing.

 15. Use four 2mm x 8mm self-tapping screws and a #1 Phillips screwdriver to secure the flap servo cover to the wing.

 16. Use a hobby knife with a #11 blade to trim two 1/4-inch (6mm) pieces from the silicone tubing.

 18. Use the radio system to center the flap servo. Connect the metal clevis to the outer hole of flap servo horn. The remaining clevis connects to the flap control horn. Adjust the length of the linkage so the flap is set to the mid/takeoff position of 11mm. Once the length of the linkage has been adjusted, slide the tubing over the forks of the clevises to keep them from accidentally opening in flight. Use needle nose pliers to tighten the nuts against the metal clevises.

 19. Set the switch at the transmitter to the UP flap position. Adjust the flap system values of the transmitter for the up position until the flap is aligned with the aileron. This will be the UP flap position.

E-tips

Always use threadlock on metal-to-metal fasteners to prevent them from vibrating loose.

 17. Assemble the flap linkage using the two pieces of tubing from the previous step, two 2mm nuts, two metal clevises and the 2mm x 25mm threaded rod. The length of the rod will be adjusted in the following steps.

 20. Set the switch at the transmitter to the DOWN flap position. Adjust the ATV at the transmitter for the down position until the flap is 25mm below the aileron. This will be the DOWN flap position.

E-tips

Because there can be minor differences in control horn and servo positions, do not connect the linkage as described in steps 19 and 20 to the opposite ﬂap until you have checked the throws. Doing so may cause the servo to bind in the UP position, which could cause damage to the ﬂap servo.

 21. Repeat steps 3 through 18 to install the remaining flap servo and assemble the flap linkage. Connect the flap linkage to the flap control horn ONLY at this time.

 22. Set the flap switch to the UP flap position. Connect the linkage to the flap servo and adjust its length until the flap is aligned with the aileron. This will be the UP flap position.

WING SPAR INSTALLATION

Required Parts

Fuselage Carbon wing spar (2) 8-32 x 1/4-inch socket head screw

(4)

Required Tools and Adhesives

Low-tack tape Phillips screwdriver: #1 15-minute epoxy Mixing cup Paper towels Mixing stick Epoxy brush Rubbing alcohol Ruler Medium grit sandpaper Petroleum jelly Felt-tipped pen Ball driver: 9/64-inch

 1. Use a #1 Phillips screwdriver to remove the four 2mm x 8mm screws that hold the fan cover to the fuselage. Set the screws and cover aside in a safe location.

Wing panel assembly (right and left)

E-tips

You may have to ﬁne-tune both ﬂap linkages up or down so they align at all three positions: up, middle, and down. It is very important to use servo arms positioned at the same angle on the splines of the servo so the travel will match in all positions.

 2. Slide the canopy hatch pin rearward and lift the canopy from the fuselage. The canopy is held in place with two pins at the front. Set the canopy aside so it doesn’t get damaged.

 3. Use a 9/64-inch ball driver to start the four 8-32 x 1/4-inch socket head bolts in the aluminum wing sockets inside the fuselage. Only thread the screws in a few turns at this time. Use care not to cross-thread the screws and damage the threads in the aluminum sockets.

 6. Remove the spar from the spar pocket. Use medium grit sandpaper to lightly sand the spar where it fits into the wing. Sand both the front and back of the spar.

 4. Locate the carbon wing spar. Use a straight edge or rest the joiner on a flat surface. The top of the joiner is flat, while the bottom will have a slight angle as shown in the drawing. This is necessary to conform to the dihedral built into the model.

Top

*Not to scale

 5. Slide the carbon wing spar in the spar pocket of the wing, narrow end first. Make sure the top of the spar is to the top of the wing. The spar will slide in easily, so don’t force it in any further than it will slide. Use a felt-tipped pen to mark the spar at the wing root.

 7. Slide the spar into the spar pocket in the fuselage. It will easily slide into the pocket up to the line made in step 5. If not, the screws installed in step 3 may be in the way and will need to be loosened.

 8. Move the string used to pull the retract servo lead through the wing into the wing so it doesn’t interfere with the fit of the wing to the fuselage.

 9. Check the fit of the wing on the fuselage. It must rest tightly against the fuselage. If the spar fits into the wing and fuselage spar pockets without any problems, the fit should be perfect. Make sure to guide the leads for the aileron and flap into the fuselage so they don’t interfere with the fit.

 10. Remove the wing and spar from the fuselage. Apply a thin coat of petroleum jelly to the fuselage around the wing socket. This will keep you from accidentally gluing the wing to the fuselage during the following procedure.

 12. Use an epoxy brush to apply epoxy to the front, back, top and bottom of the spar where it fits into the wing.

 13. Slide the spar into the spar pocket of the wing, making sure it is oriented correctly. Use a paper towel and rubbing alcohol to remove any excess epoxy from the wing and spar.

E-tips

Before mixing any epoxy, make sure to read through and understand the following steps. It is important to perform these steps before the epoxy fully cures.

 11. Mix 1/2 ounce (15mL) of 15-minute epoxy. Apply the epoxy to the spar pocket of the wing using a mixing stick.

E-tips

Epoxy will ooze out from the spar pocket of the wing. If epoxy does not ooze out, not enough epoxy was used to glue the spar into the wing.

 14. Before the epoxy cures, slide the wing into position against the fuselage. Keep the wing tight against the fuselage until the epoxy fully cures. You can use a 9/64-inch ball driver to lightly tighten the screws to secure the wing joiner in the fuselage, and low-tack tape to hold the wing in position until the epoxy has cured.

 15. Once the epoxy has cured, remove the wing panel from the fuselage. Repeat steps 4 through 14 to install the remaining wing panel to the fuselage.

 3. Prepare a 5/64-inch (2mm) drill bit by wrapping a piece of low-tack tape around the drill bit 5/8-inch (16mm) from the end of the bit. This will act as a marker so you don’t accidentally drill through the top of the wing. Place the drill bit in a drill.

 1. Use a hobby knife with a new #11 blade to remove the covering to access the landing gear mounts. Leave 1/32-inch (1mm) of covering around the inside edges. Use a trim seal tool to iron down the covering around the edges to finish the opening.

 2. Place a main landing gear block in the wing. It may distort the covering slightly during its installation. Make sure it is resting flat on the landing gear rails.

 4. Use the drill and drill bit prepared in the previous step to drill the four holes for the landing gear block mounting screws.

 5. Remove the landing gear block from the wing. Use a #1 Phillips screwdriver to thread a 3mm x 14mm countersunk self-tapping screw in each hole to cut threads into the landing gear rails. Remove the screws after threading the holes.

 6. Place 2–3 drops of thin CA in each of the holes. This will harden the threads made by the screws making them more secure when the landing gear block is installed.

 9. With the flap lowered, rest a square against the flap hinge line. Look down on the axle and check that it is perpendicular to the square as shown. If not, it may be necessary to lightly file the flat areas on the landing gear wire to correct for any misalignment.

E-tips

Always use threadlock on metal-to-metal fasteners to prevent them from vibrating loose.

 7. Slide a main gear strut into the main landing gear block. Use the setscrews and a 1.5mm hex wrench to secure the main gear wire in the block. The setscrews will tighten down on each side of the flat at the top of the strut to prevent the strut from rotating in the block. Assemble the right and left main gear assemblies at this time.

 8. Place the correct main gear assembly in position. The axle will face to the root of the wing, and the spring will face to the trailing edge of the wing. Use four 3mm x 14mm countersunk self-tapping screws and a #1 Phillips screwdriver to tighten the screws.

 10. Select the correct adapter that fits to the landing gear strut. Insert two adapters in either side of the hub of the wheel.

 11. Use a flat file to make a 1/4-inch (6mm) wide flat area on the gear near the end of the axle strut for the setscrew to rest. This will keep the wheel collar from vibrating loose in flight.

E-tips

The end of the axles may have a slight bur on them from the factory. If the wheel is hard to install use a ﬁle to remove this bur.

Always use threadlock on metal-to-metal fasteners to prevent them from vibrating loose.

E-tips

We have designed the main gear struts to work with both the ﬁxed gear and the suggested retracts. These struts are designed for the weight and speeds of the Habu. Use the struts supplied with the kit for the retract assemblies.

E-tips

Always use threadlock on metal-to-metal fasteners to prevent them from vibrating loose.

 8. Slide a main gear strut into the retract mechanism. Use the setscrews and a 1.5mm hex wrench to secure the main gear wire in the mechanism. The setscrews will tighten down on the flats at the top of the strut to prevent the strut from rotating in the block. Assemble the right and left main gear retract assemblies at this time.

NOTE: The first shipment of EFL 15–25 size retracts were shipped with only one setscrew holding in the main strut. This is fine for the lower weight limits of the retracts, but for the higher end of the weight limits, we suggest using a setscrew in each side of the strut. Future shipments will have a setscrew in each side of the unit. If your units only have a setscrew in one side of the unit, remove another setscrew for each of the fixed gear units supplied with the kit.

 11. Use the string to pull the lead through the wing and out at the root rib as shown. Remove the string once the lead has been pulled through.

 12. Place the correct retract assembly in position. The axle will face to the root of the wing, and the spring will face to the trailing edge of the wing. Use four 3mm x 14mm countersunk self-tapping screws and a #1 Phillips screwdriver to tighten the screws.

 9. Secure a 3-inch (76mm) servo extension to the lead on the retract mechanism using string or a commercially available connector.

 10. Tie the end of the string around the end of the extension. Use care not to pull the string from the wing.

 14. Select the correct adapter that fits to the landing gear strut. Insert two adapters in either side of the hub of the wheel.

 15. With the flap lowered, rest a square against the flap hinge line. Look down on the axle and check that it is perpendicular to the square as shown. If not, it may be necessary to lightly file the flat areas on the landing gear wire to correct for any misalignment.

The end of the axles may have a slight bur on them from the factory. If the wheel is hard to install use a ﬁle to remove this bur.

 18. Check to make sure the axle is flush with the edge of the outer wheel collar. If not, use a rotary tool and cutoff wheel to trim the axle flush with the wheel collar. Make sure to remove the wheel so the heat generated from the cutting does not melt the bushings in the wheel.

 19. Check the operation of the retract using the radio system. The wheel will retract into the center of the wheel well. If not, slightly bend the strut so it does.

 2. Draw two lines on the door that are 7/8-inch (22mm) and 25/8- inch (65mm) from the top edge of the landing gear door as the center lines for the mounting blocks.

 20. Repeat steps 1 through 19 to install the remaining main landing gear and wheel.

NOTE: The installation of the landing gear doors is optional and they can be installed at any time during the life of your model.

 3. Use a pin vise and 1/16-inch (1.5mm) drill bit to drill four holes in the landing gear door that are 3/16-inch (5mm) from the centerline along the lines drawn in the previous step.

 4. Use a straight edge or ruler to lightly bend the landing gear door so it will rest tightly against the wing when the gear are retracted. Work slowly to avoid cracking the paint on the outside of the landing gear door.

 1. Use a pencil to draw a centerline on the unpainted side of the landing gear door.

 5. Locate the landing gear door blocks. Use a sanding block and medium grit sandpaper to sand an angle on the notched side so the block will rest flat against the angle of the landing gear door. Prepare both blocks at this time.

 6. Rest the landing gear door block on the gear door, centering it on the lines previously drawn. Use a pencil to transfer the mounting holes from the landing gear door onto the block.

 8. Use a sanding block and medium grit sandpaper to round the back of the landing gear door block. This will allow the gear to retract into the wing and help center the gear while it is retracting.

 9. Use a #0 Phillips screwdriver to install a 2mm x 8mm self-tapping screw in each of the mounting holes in the landing gear door block. Remove the screws after cutting the threads in the blocks.

 7. Use a drill and 1/16-inch (1.5mm) drill bit to drill the two mounting holes in the landing gear door block.
