Use a felt-tipped pen to mark the center of the slot in the hinges on both the wing and control surface. 3. Place a T-pin in the center of each hinge. This will keep the hinges centered when they are installed. 2. Separate the aileron from the wing. Set the hinges aside. Use a pin vise or rotary tool and 1/16-inch (1.5mm) drill bit to drill the center location in the trailing edge and control surface previously marked. 5 EN J-3 Cub 10cc ARF/PNP REMOVING WRINKLES The covering of your model may develop wrinkles during shipping. Use a sealing iron (HAN1017) with a sealing iron sock (HAN1018) to remove them. Start with a lower heat setting and use caution while working around areas where the colors overlap to prevent separating the colors. It is also advised to use caution around the canopy as it is plastic and could distort with excessive heat. Avoid using too much heat, especially near seams, which could also separate the fi lm. Placing a cool damp cloth on adjacent colors will also help prevent the separation of the colors while removing wrinkles. A heat gun (HAN100) can also be used, but with caution as it produces extreme heat and it is easy to damage the covering. BUILDING PRECAUTIONS Prepare the work surface prior to beginning the build. The surface should be soft and free of any sharp objects. We recommend resting the airframe parts on a soft towel or pit mat to prevent scratching or denting the surface of the aircraft. TRANSPORTATION AND STORAGE When transporting and storing your model, you will need a minimum of 85 in (2.2 m) in length, and 29 inches (74cm) in height to accommodate the size of the fuselage. We also recommend the use of wing and stabilizer bags to help protect these surfaces during transport and storage. The control horns and linkages can cause damage to other surfaces even when placed in storage bags. Always transport and store the wings and stabilizer so the linkages do not contact other panels to prevent damage. REPLACEMENT COVERING Your model is covered with UltraCote® fi lm in the following colors. If repairs are required, order these coverings to make those repairs. HANU884 Cub Yellow (Oracover 30) HANU874 Black (Oracover 71) CHECKING BLIND NUTS When building the aircraft, you will be required to thread machine screws into blind nuts. We recommend pre-threading the screws to make sure the blind nuts are clear of any debris. If the screws do not thread in easily, clear the threads using the appropriate tap and tap handle. USING THIS MANUAL This manual covers the assembly of both the ARF and PNP versions of this aircraft. Please read through the manual to identify which sections pertain to your particular model. The section on Page 5 starting with “Aileron Hinging” covers the ARF build. The section on Page 23 starting with “Empennage Installation” covers the PNP build. The section starting on Page 26 starting with “Battery and Receiver Installation” covers items for both the ARF and PNP versions of the model. 4. Fit the hinge in the hinge slot. Align the slot in the hinge with the hole in the wing. 5. Fit the aileron into position on the hinges. Remove the T-pins from the hinges. 6. Check the gap between the wing and aileron at both ends. Adjust so the gap is identical. 7. Apply several drops of thin CA to each of the hinges, both on the top and bottom of the hinge.  Do not use accelerator. The CA must be allowed to wick into the hinge to provide the best bond between the hinge and surrounding wood.  Check the opposite side of the surfaces to ensure that excess CA hasn’t run. If this has occurred, use CA debonder or acetone to remove it before it cures completely. Keeping the wing horizontal will help avoid this. 8. Once the CA has fully cured, gently pull on the wing and aileron to make sure the hinges are secure.  Reapply CA to any hinges that are not glued securely. AILERON SERVO INSTALLATION 10. Thread an M2 x 10mm self-tapping screw into each of the three holes for securing the aileron control horn to the aileron. Remove the screws before proceeding. 9. Break in the hinges by flexing the control surface through its range of motion in both directions.  Repeat this section to install the remaining aileron. 6 EN 11. Apply 1–2 drops of thin CA in each hole to harden the surrounding wood. Allow the CA to fully cure before proceeding. 12. Secure the control horn to the aileron using three M2 x 10mm self-tapping screws and a #1 Phillips screwdriver. 14. Install the rubber grommets and eyelets in the servo mounting tabs following the instructions provided with the servo. 15. Use a pin vise or drill and 5/64-inch (2mm) drill bit to drill through the holes in the servo mount. 13. Remove the aileron servo hatch from the wing. 16. Thread a servo mounting screw into each hole, then remove all the screws. 17. Apply 1–2 drops of thin CA in each hole to harden the surrounding wood. Allow the CA to fully cure before proceeding. 19. Mount the servo using the screws provided with the servo. Note the orientation of the servo on the servo cover 20. Center the servo using a screwdriver or the radio system. Place the control horn on the servo so it is perpendicular to the servo. Remove any arms from the servo horn that will interfere with the operation of the servo. 18. Position the servo with the servo output shaft centered in the opening for the servo arm. 7 EN J-3 Cub 10cc ARF/PNP 21. When attaching the linkage to the servo arm, use the hole that is 5/8 inch (16mm) from the center of the servo horn. This hole will need to be enlarged using a pin vise and 5/64- inch (2mm) drill bit. 22. Secure a 9-inch (225mm) servo extension to the servo lead using a commercially available retainer (Servo Connector Clips, SPMA3054). 24. Thread an M2 x 10mm self-tapping screw into each of the holes for securing the aileron servo cover to the wing. Remove the screws before proceeding. Apply 1–2 drops of thin CA in each hole to harden the surrounding wood. Allow the CA to fully cure before proceeding. 25. Tie or tape the string located inside the wing to the end of the servo lead. 23. Use a toothpick or hobby knife with a #11 blade to puncture the servo cover for the mounting screws. 26. Guide the servo lead for the aileron through the wing to the wing root. 27. Place an M2 washer on each of the four M2 x 10mm self- tapping screws that will be used to secure the aileron servo cover. 28. Secure the aileron servo cover using a #1 Phillips screwdriver and four M2 x 10mm self-tapping screws. 29. Apply a small piece of low-tack tape to the aileron to keep it centered when preparing the aileron linkage. 30. Locate the 7 1 /8 inch (181mm) aileron linkage. Thread the clevis on threaded rod until the end of the threaded rod is visible between the forks of the clevis. 8 EN 5/8 inch (16mm) 31. Attach the clevis to the outer hole of the aileron control horn. 32. Use a felt-tipped pen to mark the linkage where it crossed the hole in the servo arm prepared earlier in this section. 34. Trim the wire 1/4-inch (6mm) above the bend in the wire. Use a fl at fi le to remove any sharp edges that remain from cutting the wire. 35. Remove the tape holding the aileron in position. Attach the clevis to the control horn. Insert the wire into the hole in the aileron servo arm. 33. Remove the linkage and make a 90-degree bend in the wire at the mark made in the previous step. 36. Check the alignment between the wing and aileron. Adjust the clevis if necessary so they are aligned. 37. Slide the nylon retainer on the wire. 39. Slide the silicone retainer over the forks of the clevis. 40. Tighten the nut against the clevis to prevent it from vibrating loose, then apply a very small amount of medium-strength threadlock.  Repeat this section for the remaining aileron servo. 38. Use pliers to snap the retainer on the wire, securing the wire to the servo arm. 9 EN J-3 Cub 10cc ARF/PNP WING STRUT INSTALLATION 41. Attach the strut fitting near the aileron to the bottom of the wing using four M3 x 12 socket head cap screws and four M3 lock washers. Apply a drop of threadlock on each screw before tightening them using a 2.5mm hex wrench.  Do not tighten the screws so much that the wing sheeting is compressed. 42. Thread the strut ends on the wing struts. There are two front struts (slightly shorter) and two rear struts (longer) for each wing panel. 43. Attach the struts to the brackets using an M3 x 15mm socket head cap screw and M3 lock nut. 44. Check the position on the holes in the struts in comparison to the jury strut holes in the wing. The holes in the strut will be close to the holes in the wing when installed correctly. 45. Attach the jury strut to the main struts using two nylon straps and four M3 x 10 socket head cap screws. Tighten the screws using a 2.5mm hex wrench. 46. Thread an M3 lock nut on each of the screws to secure their position. Tighten the nuts using a an M5.5 nut driver.  Repeat this section to install the remaining strut assembly. WING INSTALLATION 47. Attach the strut mounting tabs to the fuselage using four M3 x 10mm button head screws and a 1.5mm hex wrench. 10 EN   48. Slide the wing tube into the wing tube socket. 49. Remove the windshield hatch from the fuselage. It is secured quite fi rmly with four magnet retainers. You may fi nd it easier to grip each side of the windshield towards the top, and pull forward.Another good method is to separate the top of the hatch with a thin plastic wedge.  Avoid picking at the top edge, as it may be possible to separate the windshield from the frame. 50. The top hatch has an internal spring-loaded latch. Release the hatch by pulling the latch forward, then pushing upwards. 51. Slide the wing tube in the socket in the fuselage. 52. Slide the wing panel tight against the fuselage, guiding the aileron lead into the fuselage. Secure the wing panel using the 1/4-20 nylon wing bolt. 53. The jury strut ends will fit into the holes in the underside of the wing. 54. Adjust the strut end so the hole in the strut end aligns with the hole in the mounting tab. The strut ends fi t above the tab. Insert the pin from the fuselage side and slide the retaining clip through the hole in the pin.  When the fuselage is supported inverted, the weight of the wings will naturally set the correct dihedral. Adjust the strut ends in this position. When/if assembling the model upright, this will cause the strut ends to not quite align, which is normal. Use slight pressure to align the holes, then insert the pins. 55. Repeat the above process for the remaining strut. 56. With the strut attached, use needle nose pliers to tighten the nuts against the strut end fi ttings to keep them from vibrating loose.  Use threadlock on all metal-to-metal fasteners.  Install the remaining wing panel before proceeding. ELEVATOR INSTALLATION 57. Separate the elevators from the stabilizer. Set the hinges, joiner wire and elevators aside.  Make sure to prepare the hinge slots in the elevators and stabilizer as outing in the aileron installation section. 11 EN J-3 Cub 10cc ARF/PNP 58. Place the stabilizer on the fuselage. Center the stabilizer on the fuselage.  The elevator can be left in position to aid in centering the stabilizer. 59. Stand back 8-10 feet (2-3 meters) and check that the stabilizer is aligned with the wing. Lightly sand the stabilizer saddle on the fuselage, if necessary, to correct any misalignment. 61. Use a felt-tipped pen to transfer the fuselage outline onto the top and bottom of the stabilizer. 60. Measure from each wing tip to each stabilizer tip. Adjust the stabilizer so the measurements are the same for both sides. 62. 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, which may weaken the stabilizer. Remove any lines from the stabilizer using a paper towel and isopropyl alcohol. 63. Mix 20g of 30-minute epoxy. Use an epoxy brush to apply epoxy to the exposed wood on the top and bottom of the stabilizer. 64. Slide the stabilizer into position. Remove any epoxy from the fuselage and stabilizer using a paper towel and isopropyl alcohol. There will be excess epoxy, so use a few paper towels to properly remove it from the outside of the model.  Check the alignment as the epoxy cures. 65. Use medium grit sandpaper to roughen the joiner wire where it will contact the elevators. 66. Use isopropyl alcohol and a paper towel to remove any oils or debris from the joiner wire. 12 EN A A A=A A A A=A A=A A A 67. Use a toothpick or hobby knife to puncture the covering so the control horn mounting screws can be installed. 68. Use a hobby knife with a #11 blade to separate the control horn back plate from the control horn. 70. Slide the control horn on the screws, then secure the control horn using three M2 nuts. Tighten the nuts, avoiding crushing the underlying structure. 71. Apply a drop of thin CA to a toothpick., Use the toothpick to apply the CA to the exposed threads of the screws. 69. Insert three M2 x 15mm machine screws through the back plate, then into the holes in the elevator. Note the positioning of the back plate in relationship to the elevator. 72. Place a T-pin in the center of each hinge. This will keep the hinges centered when they are installed. Insert the hinges in the elevator 73. Tape a piece of clear packaging or waxed paper to the area where the joiner will fit to avoid gluing it to the stabilizer during its installation. 75. Apply epoxy to the area of the elevators where the joiner wire will fit.  Make sure to read through and test fit the elevators in the following steps before mixing any epoxy. 74. Slide the joiner wire into position. Apply a small amount of 30-minute epoxy to the joiner wire where it will contact the elevators. 76. Fit the elevators in position with the hinges. The joiner wire will fi t fully into the elevators. Allow the epoxy fully cure before proceeding. 13 EN J-3 Cub 10cc ARF/PNP 77. Remove the clear packaging (or waxed paper). Use a hobby knife to remove any excess epoxy if necessary. 81. Use the technique outlined for the elevator joiner wire to prepare and glue the tail gear wire into position using 5-minute epoxy. 83. Hinge the rudder to the fin using three hinges. The hinging process has been outlined earlier in this manual. Make sure there is enough clearance between the fin and rudder at the top of the fin so it can move without interference. 84. Secure the tail wheel bracket using two M3 x 10 sheet metal screws. The rigging wire bracket will fi t between the fuselage and tail wheel bracket as shown. 82. Install the rudder control horn using three M2 x 15mm machine screws and three M2 nuts. Use the instructions from the elevator control horn installation as a guide. 85. Slide the wheel collar against the tail wheel bracket and tighten the setscrew. 78. Apply several drops of thin CA to each of the hinges, both on the top and bottom of the hinge.  Do not use accelerator. The CA must be allowed to wick into the hinge to provide the best bond between the hinge and surrounding wood.  Check the opposite side of the surfaces to ensure that excess CA hasn’t run. If this has occurred, use CA debonder or acetone to remove it before it cures completely. RUDDER INSTALLATION 80. Loosen the setscrew in the wheel collar using a 1.5mm hex wrench. Slide the tail wheel bracket (small hole) onto the tail gear wire. 79. Remove the wing panels from the fuselage. Place the foam tubing on the jury struts to prevent damage to the wing during transport or storage. 14 EN TAIL RIGGING 86. Bend each of the aluminum cable tabs slightly using pliers. 87. Slide an M3 x 14mm machine screw through the pre-bent aluminum cable tab. Slide the screw through the hole in the top side of the stabilizer. 89. Thread a clevis on the cable fitting so the threaded end is barely visible between the forks of the clevis. Prepare all four of the cable fi tting end. 90. Slide the sleeve on the end of the cable. 88. Slide a second tab on the screw from the bottom of the stabilizer. Secure the tabs using an M3 nut. Use threadlock on all metal-to-metal fasteners.  Install tabs on the left and right of the stabilizer, and near the top of the fin.  Do not overtighten the hardware and compress the wood structure of the stabilizer or fin. 91. Slide the cable through the hole in the fitting 92. Pass the cable back through the sleeve. Use crimping pliers to secure the sleeve to the cable. Prepare four of the cables at this time so each has a fitting on one end of the cable. 94. Slide the sleeve on the end of the cable. Slide the cable through the hole in the bracket. Pass the cable back through the sleeve. Apply light tension on the cable and use crimping pliers to secure the sleeve to the cable. 95. Use side cutters to trim any excess wire that may interfere with the operation of your model. 93. Attach the clevis to the tabs located on the elevator.  When installing the cable ends, make sure the cable does not loop over and get stuck on the fitting. 15 EN J-3 Cub 10cc ARF/PNP 96. Install the remaining rigging to complete the tail installation. LANDING GEAR INSTALLATION  Skip to Step 103 if wheel pants are not going to be installed. 97. Install the wheel pant bracket using two M3 x 10mm button head screws. Tighten the screws using a 2mm hex wrench.  Use a drop of threadlock on all metal-to-metal fasteners. 99. Slide the wheel pant, then a wheel collar, onto the axle. 100. Slide the wheel on the axle. The assembly can then be slid fully onto the axle. 102. Tighten the setscrew in the wheel pant bracket to secure the wheel pant to the axle. The wheel pant center line will be parallel to the top edge of the landing gear.  It may be necessary to alter the flat area slightly to achieve the correct alignment of the wheel pant.  Use a drop of threadlock on all metal-to-metal fasteners. 101. Secure the wheel using a wheel collar and setscrew on the outside edge of the wheel. Make sure the wheel can rotate freely on the axle.  Use a very small drop of threadlock on the wheel collar setscrews. An excessive amount can make them difficult to remove. 98. Use a fi le to make two 1/2-inch (13mm) wide fl at areas on the bottom of the axle. The fi rst area is near the gear, and the second is near the end of the axle. 16 EN 108. Slide the inside wheel collar against the wheel and tighten the setscrew. Make sure the wheel; can rotate freely. 111. Attach the landing gear to the fuselage using two flat landing gear straps at the rear and two saddle straps at the front. Secure the straps using eight M3 x 10 sheet metal screws. RUDDER AND ELEVATOR SERVO INSTALLATION 112. Mount the rudder and elevator servos in the fuselage. Follow the same procedure as mounting the aileron servos. The output shaft of the servos will face toward the front of the fuselage. 110. DuBro J-3 wheels can be installed as an option. Make sure to follow the instructions included with the wheels.  The axle will need to be shimmed. This can be done with a wrap of aluminum tape, in the forward-rotation direction. Another option is thin-wall tubing. The axle will also require trimming to length, approximately 37mm, to allow installation of the hubcap. 103. Use a fi le to make two 1/2-inch (13mm) wide fl at areas on the bottom of the axle. The fi rst area is near the gear, and the second is near the end of the axle. 104. Slide a wheel collar on the axle. 106. Slide the wheel on the axle. 105. Inspect the wheel. One side has three holes to attach the hub cap to the wheel. These holes need to face outboard. 107. Slide a wheel collar on the axle. Tighten the setscrew so the wheel collar is flush with the end of the axle. 109. Attach the hub cap using three M2 x 6mm countersunk screws. Use a #1 Phillips screwdriver to tighten the screws. 17 EN J-3 Cub 10cc ARF/PNP 118. Use a felt-tipped pen to mark the pushrod wire where it crosses the servo arm. 119. Remove the clevis from the pushrod wire. Prepare the wire by bending it and securing it to the control horn as outline with the aileron servo installation. 120. Slide the pushrod wire back into the pushrod tube. Reinstall the servo arm and secure it using the hardware included with the servo. 113. Center the servos using the radio system. Place the servo arm on the servos so they are 90-degrees to the servo center line. Remove any arms that may interfere with the operation of the linkages. 114. Remove the clevis and nut from the long pushrod. Insert the pushrod into the tube from inside the fuselage. 115. Attach the clevis to the rudder control horn. 116. Use tape or clamps to hold the rudder in alignment with the fi n. 117. When attaching the linkage to the rudder and elevator servo arms, use the hole that is 13/16 inch in (21mm) from the center of the servo horn.

Tighten the setscrew so the wheel collar is flush with the end of the axle. LANDING GEAR INSTALLATION 182. Use a fi le to make two 1/2-inch (13mm) wide fl at areas on the bottom of the axle. The fi rst area is near the gear, and the second is near the end of the axle. 187. Slide the inside wheel collar against the wheel and tighten the setscrew. Make sure the wheel; can rotate freely. 183. Slide a wheel collar on the axle. 188. Attach the hub cap using three M2 x 6mm countersunk screws. Use a #1 Phillips screwdriver to tighten the screws. 184. Inspect the wheel. One side has three holes to attach the hub cap to the wheel. These holes need to face toward the outside of the landing gear. 189. DuBro J-3 wheels can be installed as an option. Make sure to follow the instructions included with the wheels.  The axle will need to be shimmed. This can be done with a wrap of aluminum tape, in the forward-rotation direction. Another option is thin-wall tubing. The axle will also require trimming to length, approximately 37mm, to allow installation of the hubcap. 185. Slide the wheel on the axle. 190. Attach the landing gear to the fuselage using two flat landing gear straps at the rear and two saddle straps at the front. Secure the straps using eight M3 x 10 sheet metal screws. 26 EN BATTERY AND RECEIVER INSTALLATION 191. Place the battery in the fuselage, and use the hook and loop strap to secure the battery. Make sure not to cover any warning labels on the battery.  The placement of the battery can be changed to adjust the Center of Gravity. Once adjusted, mark the location of the battery so it can be returned to the correct location when installed after charging. 196. Three struts are installed in the rear bracket. From front to back these are; diagonal strut, rear strut with bushing, spreader bar. 192. Install the receiver in the fuselage using double-sided foam tape. Refer to the receiver instructions for more details on mounting the receiver and routing the antenna. Connect the leads to the appropriate channels of the receiver.  The rear strut uses a bushing to allow the strut to properly fit to the correct diameter in the bracket. These bushings are supplied with the float strut set. This step is for the ARF only. 193. Plug the extensions for the aileron servos into the receiver. Route the leads for the ailerons through the holes in the formers and through the openings in the sides of the fuselage. 197. The forward bracket receives the forward strut, and a spreader bar, in that order. 194. Glue the seat(s) in the cockpit using contact adhesive, or hook and loop tape. Position the seats between the battery and receiver. 198. Use a hobby knife and #11 blade to cut a slit in the covering for the rear strut. Use a covering iron to seal the covering into the slot. FLOAT INSTALLATION 195. Assemble the floats following the instructions included with the fl oats. Use the mounting positions shown for the strut mounting locations.  The front bracket will be in the rear position, and the rear bracket will be in the front position. 199. Fit the strut and diagonal strut in the forward slot. Secure the two struts using two landing gear straps and four M3 x 10 sheet metal screws.  The strut and diagonal strut stack in the slot, and use the same saddle clamps as the landing gear. 27 EN J-3 Cub 10cc ARF/PNP 200. Locate the four holes for the landing gear straps on the bottom of the fuselage. Use a hobby knife and #11 blade to expose the holes. Secure the rear strut using two landing gear straps and four M3 x 10 sheet metal screws. 201. Use tape to secure the lead for the water rudder to the float and strut so it doesn’t interfere with the operation of the model. 202. The fl oat steering servo lead will reach the receiver without an extension lead in most installations. One option to route the lead is to simply cut a small slit in the covering above the fl oat strut. Apply a piece of Blenderm™ tape before cutting, this will prevent the covering from tearing. Another option is to use a receptacle in the opening, and plug the float servo into the receptacle. Plug the fl oat servo into an open channel in the receiver. Mix the rudder servo to the fl oat servo for correct operation. DECAL INSTALLATION 203. Apply the decals to your model using the box art from your model as a guide to location. The internet is also a great resource for decal placement. 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.  When cleaning your model, do not use harsh chemicals on the provided decals. Test on unused decals first. 28 EN CENTER OF GRAVITY 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 flight is properly balancing the model. The Center of Gravity range supplied here is a guideline based on testing. Deviation from the measurements we provide is possible and may result in a model that suits your fl ying style better. Start with the recommended Center of Gravity, then feel free to experiment with different balance points. We advise adjusting progressively and cautiously. 1. Attach the wing panels to the fuselage. Make sure to connect the leads from the aileron and flaps 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 33 / 8 inches (85mm) behind the leading edge of the wing against the fuselage for sport fl ying. 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 fingers or a commercially available balancing stand. Use the radio system to move the gear to the up position.  The overall CG range for this model is 3–33 /4 inches (76–95mm) as shown below. We recommend starting at the measurement listed above, then adjusting to suit your particular flying style.  Nose weight may be required when using lighter engines or when floats are installed. 3–33 / 4 Inches 76–95 mm 29 EN J-3 Cub 10cc ARF/PNP 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 ruler to adjust the throw of the elevator, ailerons and rudder. Surface Rate Direction Throw Aileron High Up 1 3 /16 inch (30 mm) Down 13/16 inch (20 mm) Low Up 7/8 inch (22 mm) Down 5/8 inch (15 mm) Elevator High Up 2 3 /16 inch (55 mm) Down 23 /16 inch (55 mm) Low Up 1 1 /2 inch (38 mm) Down 11 /2 inch (38 mm) Rudder High Left 2 3 /8 inch (60 mm) Right 23 /8 inch (60 mm) Low Left 19 /16 inch (40 mm) Right 19 /16 inch (40 mm) These are guidelines from general flying from our own fl ight tests. You can experiment with higher or lower rates to match your preferred style of fl ying. Travel Adjust should be adjusted according to each individual model and preference. Always install the control horns 90 degrees to the pushrod at the servo. Use sub-trim as a last resort to center the servos. Always re-bind the radio system once all the control throws are set to keep the servos from moving to their endpoints until the transmitter and receiver connect. PREFLIGHT CHECKLIST • Charge the transmitter, receiver and motor batteries. Follow the instructions provided with the charger. Follow all manufacturer’s instructions for your electronic components. • Check the radio installation and make sure all control surfaces (aileron, elevator, rudder, and fl aps) 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. DAILY FLIGHT CHECKS • Check the battery voltage of the transmitter battery. Do not fl y below the manufacturer’s recommended voltage. Doing so can cause your aircraft to crash. • Check all hardware (linkages, screws, nuts, and bolts) prior to each day’s fl ight. Ensure that binding does not occur and that all parts are properly secured. • Ensure all surfaces are moving in the proper manner. • Perform a ground range check before each day’s fl ying session. • All servo leads and switch harness plugs should be secured in the receiver.
