Landing Gear Installation 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.
4. Remove the hardware from the axle. Place a drop of light machine oil on the axle to help the wheel roll freely. Always use threadlock on metal-to-metal fasteners to prevent them from vibrating loose. 6. Use a 2.5mm hex wrench or ball driver to secure the wheel using the shorter 4mm x 5mm button head screw and 4mm washer removed from the axle. 8. Use the longer 4mm x 12mm button head screw and 4mm washer to secure the wheel and wheel pant to the landing gear. Use a 2.

12. Secure the aileron servo cover using the four 2mm x 12mm sheet metal screws remove in step 1 and a #1 Phillips screwdriver. 13. Use a pin vise and 5/64-inch (2mm) drill bit to drill the two holes completely through the aileron for the aileron control horn mounting screws. The holes have already been started and are easily found on the bottom of the aileron 10 14. Attach the control horn to the aileron using two 2mm x 12mm sheet metal screws and a control horn backplate.
Hinging the Elevators Required Parts Stabilizer and elevator assembly Required Tools and Adhesives Pin vise Drill bit: 1/16-inch (1.5mm) Sandpaper Toothpicks 30-minute epoxy Low-tack tape Square Felt-tipped pen Thin CA T-pins Mixing cups Mixing sticks Paper towels Rubbing alcohol Ruler or straightedge 2. Use a pin vise and 1/16-inch (1.5mm) drill bit to drill a hole in the center of each hinge slot. Drill holes in both the elevators and stabilizer.
12 6. Insert the joiner wire into both elevator halves. Use low-tack tape to keep the joiner wire in position while the epoxy cures. Use a straight edge to make sure the elevator halves are in alignment with each other. Also make sure the elevator halves lay flat on your work surface. 8. Place a T-pin in the center of each of the six hinges. This will center the hinges when installed in the stabilizer. 9. Place the hinges in the stabilizer as shown. 10.
13. Once the CA has fully cured. Gently pull on the elevator to make sure the hinges are secure. If any hinges are loose, reapply CA to the hinge. Flex the elevator through its range of motion a number of times to break in the hinges. Wing and Stabilizer Installation Required Parts Fuselage assembly Wing panels (right and left) Clip (2) Stabilizer assembly Aluminum wing tube 3. Slide the tube into the socket in the fuselage.
6. Place the stabilizer in position. Use a T-pin at the rear of the stabilizer and tape at the front so it can be easily repositioned. The line drawn earlier will help in setting the initial alignment. 8. Step back from the model 3–6 feet (1–2 meters) and view the model from the rear. Check that the wing and stabilizer are in alignment with each other. You might need to lightly sand the stabilizer saddle to bring the wing and stabilizer into alignment. Check Alignment 7.
Rudder and Fin Installation 12. Lightly brush epoxy on the exposed wood on the bottom of the stabilizer. Required Parts Fuselage assembly Rudder and fin assembly 2. Use a hobby knife with a new #11 blade to trim the covering 1/16 inch (1.5mm) inside the line drawn in the previous step. Required Tools and Adhesives 30-minute epoxy Epoxy brush Square Felt-tipped pen Mixing cup Mixing sticks Paper towels Rubbing alcohol Low-tack tape Thin CA Pin vise Drill bit: 1/16-inch (1.
4. Brush a thin layer of epoxy on the bottom of the fin as shown. 6. Use a square to make sure the fin is aligned with the stabilizer. 5. Position the fin back on the fuselage. Use a paper towel and rubbing alcohol to remove any excess epoxy. 7. Use low-tack tape to keep the fin in alignment with the stabilizer until the epoxy fully cures. 16 8. Use a pin vise and 1/16-inch (1.5mm) drill bit to drill a hole in the center of each hinge slot.
10. Insert the hinges in the rudder. 12. Once the CA has fully cured. Gently pull on the rudder to make sure the hinges are secure. If any hinges are loose, reapply CA and flex the rudder through its range of motion a number of times to break them in.
2. Remove the servo from the fuselage. Use a pin vise and 1/16-inch (1.5mm) drill bit to drill the four holes for the servo mounting screws. 4. Place 2–3 drops of thin CA in each hole to harden the surrounding wood. This harder surface makes the screws more secure when installed. 3. Use a #1 Phillips screwdriver to thread a servo mounting screw into each of the holes to cut threads in the surrounding wood. Remove the screw before moving to the next step.
8. Use a pin vise and 5/64-inch (2mm) drill bit to drill the two locations for the control horn mounting screws. The locations have been predrilled at the factory. 10. Use a square or straight edge to make sure the rudder is in alignment with the fin. The clevis attaches to the outer hole on the control horn. Adjust the clevis as necessary so the rudder is aligned with the fin when the rudder servo is centered.
Motor and Speed Control Installation 2b. Attach the Power 25 motor to the firewall using four 7mm spacers, 3mm x 20mm button head screws and four 3mm lock washers. Tighten the screws using a 2mm hex wrench or ball driver. 3. Route the leads for the motor through the hole in the firewall.
4. Loop a tie-wrap (not included) through the plate in the fuselage right above the landing gear plate. Make sure the tie-wrap is not looped through the battery mounting plate. 5. Slide the speed control into the fuselage with the battery wires, receiver lead and switch going in and through the tie-wrap. Position the speed control, then tighten the tie-wrap to secure the speed control in the fuselage. The heat sink will face the top of the fuselage. E-flite Shoestring 15e ARF Assembly Manual 7.
Cowling Installation Required Parts Fuselage assembly Cowling Canopy Propeller 2mm x 6mm sheet metal screw (4) Spinner backplate with adapter (not included) 2. Place the canopy back on the fuselage and attach the wings. Slide the cowl on the fuselage. You will need to flex the cowl to fit it over the landing gear fairings on the bottom of the fuselage. 4. Slide the propeller adapter and spinner backplate on the motor shaft. Check that the cowl is aligned with the spinner backplate.
7. Remove the cowl from the fuselage. Use a #1 Phillips screwdriver to thread a 2mm x 6mm sheet metal screw into the cowl mounting holes to cut threads in the surrounding wood. Remove the screw before moving to the next step. Prepare all four mounting holes at this time. 8. Remove the cowl from the fuselage. Place 1–2 drops of thin CA in each hole to harden the surrounding wood. This harder surface makes the screws more secure when installed. E-flite Shoestring 15e ARF Assembly Manual 9.
Decal Installation Required Parts Fuselage assembly Wing assembly Required Tools and Adhesives Spray bottle Dish washing detergent Paper towel Hobby knife with #11 blade 24 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 sprayed in the location of the decal to allow repositioning. Use a paper towel as a squeegee to remove excess water from under the decal.
3. When balancing your model, support the plane upright at the marks made on the bottom of the wing with your fingers or a commercially available balancing stand. This is the correct balance point for your model. Make sure your model is assembled and ready for flight before balancing. 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 right, the rudder should also move right.
Preflight Check Your Radio Before going to the field, make sure your batteries are fully charged per the instructions included with your radio. Charge the transmitter and motor battery for your airplane. Use the recommended charger supplied with your particular radio system, following the instructions provided with the radio. In most cases, the radio should be charged the night before going out flying. Before each flying session, range check your radio.
Take-off Landing With the high Kv motor and a small 8-inch propeller, there is a ton of torque coming from your motor, so be prepared on your first takeoff. The airplane will easily come off the ground at 1/2 throttle, so if you stop yourself from going full bore and wait to apply full power until well airborne, your takeoffs will be easier and a thing of beauty.
