Using This Manual Kit Contents This manual is divided into sections to make assembly of the model easier to understand and to provide breaks between each major section. In addition, check boxes have been placed next to each step to keep track of each step completed. Steps with a single circle (Ο) are performed once, while steps with two circles (Ο Ο) indicate that the step will require repeating, such as for a right or left wing panel, two servos, etc.
Required Equipment Radio You will need a minimum of a 4-channel radio for this model. A complete radio system can be purchased or, if you have a suitable transmitter, just the airborne components will be required. Complete System Spektrum DX6i 2.
Landing Gear Assembly and Installation Required parts: Fuselage Main landing gear (wheels installed) Wheel pants (2) 6-32 x 1/2" socket head bolts (2) #6 steel washers (4) #2 x 3/8” sheet metal screws Required tools and adhesives: 7/64” balldriver Dremel rotary tool w/ cutoff wheel 1/16 in (1.5mm) drill bit Pin drill Ο 2. Use a 7/64” balldriver to install the landing gear on the fuselage with two 6-32” x 1/2” socket head bolts and #6 steel washers.
Ο Ο 4. Using a 1/16 in (1.5mm) drill bit in a pin drill, drill two holes where marked on the wheel pant. Apply a drop of thin CA in each hole to strengthen the wood. An accurate method of aligning the wheel pants to the fuselage is to level the fuselage with a block under the rear end, then support the wheel pant with another block while marking the location holes for the attachment screws with a felt-tip marker. Ο Ο 5.
Tail Installation Required Parts Fuselage Vertical stabilizer Horizontal stabilizer (2) 4-40 x 1/4" locknuts (2) #4 steel washers Ο 2. Slide the vertical stabilizer into place. It will be necessary to deflect the rudder to the right in order for the rudder horn to clear the elevator. The 4-40 rods will pass through the horizontal stabilizer and the fuselage. The forward end of the vertical stabilizer assembly will slide over the turtledeck tab, and the fin post will slide between the aft fuselage sides.
Fuselage Servo Installation Required Items (2) Servos and hardware (2) 23 5/8” rudder and elevator pushrods (2) nylon clevises and silicone keepers (2) pushrod keepers Fuselage Radio system (Tx, Rx, battery) JR MatchMaker (optional) Required Tools 1/16 in (1.5mm) drill bit Pin drill 5/64 in (2mm) drill bit #0 Philips screwdriver Thin CA Sidecutters #1 Philips screwdriver Low-tack tape Tongue depressors/popsicle sticks Clothespins Felt-tip pen Ο Ο 1.
Ο Ο 4. Remove the servo arm using a #1 philips screwdriver. Using sidecutters, trim three of the arms from a standard four arm servo horn, leaving one long arm. Drill a 5/64 in (2mm) hole in the outermost hole using a pin drill. Center the servo using a JR MatchMaker or your radio system, and install the arm as shown using a #1 Philips screwdriver. JR’s MatchMaker is a great tool for setting up a model because it allows you to center and cycle servos without the need for a transmitter and receiver.
Ο Ο 6. Attach the clevises to the control horn on the elevator at the third hole from the mounting surface, and on the rudder at the second hole from the mounting surface. Do not install the silicone keepers at this time. We will do that later in construction on Page 27. Here are a couple of methods that work well to center the control surfaces for setup. One technique is to use a pair of tongue depressors and clothespins. Another is to use low-tack tape.
Receiver Installation Required Parts Fuselage Spektrum AR6200 Receiver Adhesive backed hook and loop tape Ο 1. Install the main and satellite receiver in the fuselage as shown with adhesive backed hook and loop tape. An alternate location for the satellite receiver is also shown. The rudder and elevator servos can be plugged in at this time.
Ο 2. Using a 3/32” balldriver, install the motor on the firewall with four 4-40 x 1/2" socket head bolts. The motor wires should exit towards the bottom of the fuselage. You may use threadlock to prevent these screws from vibrating loose in flight. Ο 3. Remove the battery hatch by sliding it forward to disengage the magnets, and lifting at the rear. It can then be pulled rearwards and off the model. 12 Ο 4. Install the battery with two hook and loop straps.
Motor and Battery Installation E-flite Power 32 Required Parts E-flite Power 32 Motor with hardware E-flite 60A ESC E-flite Battery Propeller (4) 4-40 x 3/4" socket head bolts Adhesive backed hook and loop tape (2) Hook and loop straps (4) 4mm aluminum motor mount spacers Ο 2.. Using a 3/32” balldriver, install the motor on the firewall with four 4-40 x 3/4" socket head bolts and four 4mm aluminum spacers. The motor wires should exit towards the bottom of the fuselage.
Ο 4. Install the battery with two hook and loop straps. Slots are provided on the floor of the battery compartment for the straps to pass through. The natural curl of the straps will allow them to be fed down one slot, under the battery compartment floor, then up through the opposite slot. Should you find that the rotation direction of your E-flite Power Brushless Outrunner is opposite to that needed, reversing it is just a matter of switching any two of the motor wires.
Cowling, Propeller and Spinner Installation Required Parts Fuselage Cowling (4) 4-40 x 1/4" socket head bolts (4) #4 steel washers Spinner with screws Propeller Propeller adapter (supplied with motor) Ο 2. The spinner backplate requires the hole to be enlarged to suit the propeller adapter. For a snug fit on the prop adapter the hole should be approximately 9.5mm diameter. This is best done with a tapered reamer. Proceed carefully and check the fit on the shaft as you enlarge the hole.
Ο 4. Install the spinner cone using a #1 Philips screwdriver and the supplied Philips head screws. An alternate method to drilling completely through the spinner backplate is to grind only the relief necessary to clear the propeller adapter hub.This can be done by hand using a straight cutter in a Dremel rotary tool. The remainder of the hole can be left at its orginal size and will be a good fit on the propeller shaft.
Wing Joining Required Parts Wing halves (L and R) (2) dihedral joiners (2) leading edge dowels (2) 6-32 x 1” socket head bolts (2) #6 steel washers Ο Ο 2.. Upon installation, approximately 5/16” to 3/8” of the dowel should protrude from the leading edge of the wing. Required Tools and Adhesives Low-tack tape 12-minute epoxy Clear tape 7/64” balldriver Mixing cups Mixing sticks Rubbing alcohol Paper towels Ο Ο 1. Install the leading edge dowels in the wing panels with 12-minute epoxy.
Ο 4. Apply low-tack tape to the upper and lower surfaces of the center of the wing panels as shown. This will allow for easy clean up of any excess glue and make for a clean joint. Ο 6. 12-minute epoxy is used to install the dihedral joiners and join the wing. Glue the two dihedral joiners to each other. Ο 5. Apply a piece of clear tape to the front and rear wing saddle area where the wing leading and trailing edges will come in contact with the fuselage. Ο 7.
Ο 8. Install the dihedral joiners in one wing slot and slide the other wing panel onto the joiner. Wipe off any excess epoxy that squeezes out of the joint with rubbing alcohol and a paper towel. Using a 7/64” balldriver, install the wing on the fuselage with two 6-32” x 1” socket head bolts. Tighten the bolts just enough that the wing sits snugly in the wing saddle, and that the two wing panels are exactly aligned with each other along their bottom surface.
Ο 2. A string is provided in each wing half to draw the aileron lead through the wing. Attach the end of the string to the aileron servo lead and pull it carefully through the wing to the center. Once both leads have been pulled through, they can be secured to each other with tape to prevent them falling back into the wing. Ο Ο 3. Place the servos in the wing openings and mark the screw hole locations with a felt-tip pen. 20 Ο Ο 4. Using a 1/16 in (1.
Ο Ο 6. Using a #1 Philips screwdriver remove the servo horn. Using sidecutters remove three of the four arms, leaving one long arm. Using a pin drill, enlarge the outermost hole to 5/64 in (2mm) to accept the pushrod. Center the servo and install the arm towards the wing tip as shown. Ο Ο 8. Center the aileron servo using your radio or JR MatchMaker. Attach the clevis to the aileron horn at the third hole from the surface and mark the length at the servo arm.
Canopy and Cooling Exit Scoop Required Parts Fuselage Canopy Cooling Exit Scoop Ο 2. Follow the same procedure to attach the cooling exit scoop on the lower fuselage behind the wing in the location shown. Note that the opening faces towards the rear of the model. Required Tools and Adhesives Low-tack tape Canopy Glue Ο 1. Trial fit the canopy on the fuselage. Once satisfied with its location, apply glue to the inside of the canopy at the areas of the painted frame, and install on the fuselage.
Optional Float Installation. Required parts: E-flite fiberglass 25-size Float Set Sullivan 36” flex cable Pulse XT 25e (assembled) (4) 1/8” float mount spacers (included in Pulse kit) Required tools and adhesives: #1 Philips screwdriver 7/64 in balldriver 1.5mm Allen wrench 1/16 in (1.5mm) drill bit Pin drill Felt-tip pen Threadlock Ο Ο 2. Using a #1 Philips screwdriver, attach two of the mounting brackets and spacers to each of the floats with 3mm x 12mm sheet metal screws.
Ο Ο 4. Use a file or rotary tool to make a 1/4” wide flat on the top of each of the four axles. The flat should be located approximately 9/16” (14mm) outboard of the hexagonal axle base. Ο Ο 5. Attach the floats using four 5/32” wheel collars and four 3mm setscrews using the 1.5mm Allen wrench provided in the float kit. Make sure to use threadlock when installing the setscrews in the flats made previously. Note: One of the floats has holes drilled in the aft end for the water rudder bracket.
Ο 7. Install the rudder assembly, steering arm and pushrod connector on the nylon bracket. Refer to pages 12 and 13 in the Float Set assembly manual for guidance. The pushrod connector will go in the hole closest to the rudder post. Ο 8. Install a pushrod connector on the outermost hole in the rudder horn as shown. Refer to page 13 of the Float Set assembly manual for guidance. Ο 9. The Sullivan flex cable and tube need to be cut to length prior to installation. The cable length will be approximately 31.
Ο 11. Use the two remaining full brass straps to attach the pushrod tube to the left side of the Pulse fuselage. Locate the straps as shown in the picture below using the following dimensions as a guide. There are fuselage frames at these locations; ensure that the screws are located in the center of the frame and will not interfere with any internal items such as pushrods. Ο 12. Attach the water rudder cable housing to the left float mount strut using the cable tie provided in the Float Set hardware bag.
Flight Preparation Control Directions 1. Connect the throttle lead from the ESC to the receiver. 2. Connect the wing servos to the receiver with two 3” extension leads (JSP98100) if using the dual aileron function in your transmitter, otherwise use a Y-harness (JSP98020). Attach the wing to the model. 3. Connect battery power to the ESC and using your radio verify the correct rotation of the motor. Viewed in the direction of flight, the propeller should rotate clockwise.
Preflight Center of Gravity (CG) The recommended center of gravity range for the Pulse XT 25e is 2.5 - 3.0” (63 - 76mm) behind the leading edge of the wing. Before making this measurement ensure that the model is in a ready-to-fly state, with all components in place including batteries, hatches and radio equipment. Battery Charging Use the recommended charger for the batteries being used in your radio and model, and follow the charging instructions.
