Recommended Radio Equipment You will need a minimum of a 6-channel transmitter, receiver and four servos. You can choose to purchase a complete radio system. If you are using an existing transmitter, just purchase the other required equipment separately. We recommend the crystalfree, interference-free Spektrum™ DX6i 2.4GHz DSM® 6-channel system. If using your own transmitter, we recommend the E-flite S75 Sub-Micro servos.
Landing Gear Installation 3. Slide a 3mm x 25mm machine screw through one of the 13/4-inch wheels. Thread a 3mm nylon lock nut on the screw as shown.
Optional Wheel Pants Installation Make sure the wheel can rotate freely. If not, loosen the 3mm lock nut so the 3mm nut can be backed away from the wheel. Retighten the assembly and check that the wheel can rotate freely. 5. Repeat Steps 2 through 4 for the remaining wheel. Required Parts Fuselage assembly Wheel pant (left and right) (EFL2863) 2mm x 4mm wood screw (4) Required Tools and Adhesives Phillips screwdriver: #1 1. Slide the wheel pant over the wheel.
2. Attach the Outrunner motor to the front of the firewall using two plywood X-mount spacers, four #4 washers and four 4-40 x 5/8-inch socket head screws. Tighten the screws using a 3/32-inch ball driver or hex wrench. Important Information about Your Brushless ESC 4. Connect the leads from the ESC to the leads from the motor. Use a tie wrap (not included) to secure the motor leads so they will not interfere with the operation of the motor. 5.
Cowling Installation Required Parts Fuselage w/motor installed 2mm x 8mm wood screw (4) Cowling Propeller Prop adapter (for outrunner motor) Dummy motor (optional) E-flite 13/4-inch aluminum spinner (optional) 2. Use thin CA to harden the holes in the hardwood cowl mounts. This will help to prevent the screws from vibrating loose in flight. 4. Slide the cowling onto the fuselage. Use a #1 Phillips screwdriver to secure the cowl using four 2mm x 8mm sheet metal screws.
6. An optional 13/4-inch spinner is also available for your model. It can be installed at this time. Aileron Hinging Required Parts Wing (left and right) Aileron (left and right) CA hinges (8) 2. Slide four hinges into the slits in the aileron. Center the slot in the hinge with the hole drilled in Step 1. Place a T-pin in each hinge to prevent it from being pushed into the wing when installing the aileron.
4. Firmly grasp the wing and aileron and gently pull on the aileron to ensure the hinges are secure and cannot be pulled apart. Use caution when gripping the wing and aileron to avoid crushing the structure. Placing a #11 hobby blade between the aileron leading edge and wing trailing edge to position the aileron will result in a nice free-moving hinge for 3D throws without any binding.
2. Place the servo in the wing. Guide the servo lead out through the opening at the wing root. 3. Use a pin drill and 1/16-inch (1.5mm) drill bit to drill two holes through the servo mounting tabs into the wing. Use care not to drill through the top of the wing by accident. 10 4. Apply 2–3 drops of thin CA into each hole to harden the surrounding wood. This will make the screws more secure and less likely to vibrate loose. 5.
8. Place a 3D servo horn on the aileron servo. 10. Use a pin drill and 1/16-inch (1.5mm) drill bit The horn should align with the hinge line when the to enlarge the outer hole of the aileron servo horn. radio is on and the aileron servo plugged into the receiver. There are an odd number of splines on the servo, so you may need to remove the horn and rotate it 180 degrees to get it to align correctly. 13. With the radio system on, make sure to center the aileron trim and stick.
Wing Installation Required Parts Fuselage Wing (right and left) Wing tube #4 washer (2) 4-40 x 3/8-inch machine screw (2) 3. Secure the panels using a 4-40 x 3/8-inch machine screws and #4 washers. Use a 3/32-inch hex wrench to tighten the socket head screw.
2. View the airframe from the rear and make sure the wing and stab are parallel. If not, lightly sand the stab saddle until they are. 5. Use a sharp hobby knife to cut the covering slightly inside the lines drawn. Be very careful not to cut into the underlying wood, as this will weaken the stab and cause it to fail in flight. 6. Insert the micro control horn into the slot in the elevator.
14 8. Slide the elevator into position, then the stabilizer. 9. Check the alignment and make sure everything lines up. Wick thin CA into the joint between the fuselage and stabilizer. Make sure to glue both top and bottom. Do not use accelerator—to allow the CA to wick in the joint, providing the best bond possible. 10. Slide six hinges into the slits in the elevator. Place a T-pin in each hinge to prevent it from being pushed into the elevator when attaching it to the stabilizer.
Placing a #11 hobby blade between the elevator and stabilizer to position the two will result in a nice freemoving hinge for 3D throws without any binding. E-flite Sukhoi SU-26m 480 ARF Assembly Manual 13. Work the elevator up and down several times to work in the hinges and check for proper movement. Do not use CA accelerator during the hinging process. The CA must be allowed to soak into the hinge to provide the best bond. Using accelerator will not provide enough time for this process. 11.
Rudder and Fin 2. Apply a small amount of petroleum jelly to the top and bottom of the tail wheel bushing. Work the jelly into the bushing to prevent the CA from seeping in between them and gluing them together. 3. Use 6-minute epoxy to glue the wire into the hole in the bottom of the rudder. Take care not to get epoxy on the bushing that could accidentally glue it to the rudder. Required Parts Fuselage Rudder Fin CA hinge (3) Micro control horn with backplate Tail wheel assembly 4.
6. Slide the rudder tight against the fin. Make sure to guide the tail wheel bearing into the slot at the bottom of the fin. Placing a #11 hobby blade between the elevator and stabilizer to position the two will result in a nice freemoving hinge for 3D throws without any binding. 8. Firmly grasp the rudder and gently pull on the fin to ensure the hinges are secure and cannot be pulled apart. Use caution when gripping the rudder and fin to avoid crushing the structure. 10.
12. Position the fin back onto the fuselage. Use a square to check the alignment between the fin and stabilizer. Lightly sand the bottom of the fin until the alignment is correct. Use thin CA to glue the fin to the fuselage. Also apply CA to the rudder post at the back edge of the fuselage. 13. Insert the micro control horn into the slot in the rudder. Make sure the holes in the control horn face forward and that the horn is on the side opposite the elevator control horn.
2. Use a pin drill and 1/16-inch (1.5mm) drill bit to drill holes through the servo mounting tabs and into the fuselage. 4. Use a #0 Phillips screwdriver and the screws provided with the servo to secure the elevator servo in the fuselage. 3. Apply 2–3 drops of thin CA into each of the two holes to harden the surrounding wood. 5. Use side cutters to remove one of the arms from a 3D servo horn. Use a pin drill and 1/16-inch (1.5mm) drill bit to enlarge the outer hole of the servo horn. 6.
8. Insert the bend in the 41/2-inch (115mm) pushrod wire into the middle hole of the elevator control horn. 14. Repeat Steps 1 though 13 to install the rudder servo and linkage. The linkage will also connect to the center hole of the rudder control horn and to the outside hole of the 3D servo horn. 15. Use hook and loop tape to mount the receiver and remote receiver in the fuselage. Plug the elevator, rudder and speed control leads into the appropriate ports of the receiver. 13.
Final Assembly 2. Use medium CA to glue the pilot (optional) to the canopy hatch as shown. 3. Place the canopy hatch on the fuselage. Make sure to place a piece of waxed paper or part of a bag from the packaging of your model between the hatch and fuselage so when the canopy is glued to the hatch it won’t accidentally be glued to the fuselage. Make sure that the hatch is fully seated on the fuselage, and the magnet in engaged during this step.
Control Throws 1. Turn on the transmitter and receiver of your Sukhoi SU-26m. Check the movement of the rudder using the transmitter. When the stick is moved 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.
Preflight Check Your Radio Before going to the field, be sure that your batteries are fully charged per the instructions included with your radio. Charge both the transmitter and receiver pack 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. Range Test Your Radio Before each flying session, be sure to range check your radio.
