Dornier Do X Flugschiff (Flying Ship) As It Was Called, Was Conceived by Dr

DDOORRNNIIEERR DDO XX ""FFLLYYIINNGG SSHHIIPP"" SPORT-SCALE ARF R/C MODEL AIRPLANE

The Dornier Do X Flugschiff (flying ship) as it was called, was conceived by Dr. Claude Dornier in 1924, financed by the German Transport Ministry, and produced by the Dornier company of Germany in June of 1929. With its crew of 14, wingspan greater than 157 feet, 12 engines mounted above the wing on pylons in a push-pull configuration, and a maximum takeoff weight of 123,460 pounds, it was by far the largest heavier-than-air aircraft of its time. With a smoking room that had its own wet bar, a dining salon, and seating for 66 passengers – which could be converted to sleeping berths for night flights, its passenger accommodations approached the luxurious standards of transatlantic ocean liners. To introduce the Do X to the world, it took off on November 3, 1930 from Germany to visit the Netherlands, England, France, Spain and Portugal. It arrived at New York City on August 27, 1931, where thousands of sightseers visited the Glenn Curtiss Airport (now LaGuardia Airport) to tour this leviathan of the air. Although very popular with the public, numerous non-fatal accidents and other factors prevented more than three from ever being built. Two were broken up for scrap in 1937. The remaining Do X eventually became the centerpiece of Germany's aviation museum Deutsche Luftfahrt-Sammlung (German Aviation Collection) until it was destroyed during WWII by an RAF air raid the night of November 23, 1943. This RC Dornier is about 1/20 scale and took us almost 2 years to design. Although it is flying boat, we offer an optional landing gear set with steerable tail wheel so our customers may enjoy more flights with their Dornier Do X. We invite you to enjoy the pride of ownership and the joy of flying this beautiful ARF sport-scale model.

Due to its size, weight, power, and the number of engines, this airplane is recommended only for advanced- level builders and pilots. Please read all instructions carefully even if you are an experienced builder. Any assembling, testing or flying of this airplane is done entirely at your own risk. 2. Use a receiver battery to power your radio system. Do not use the battery eliminator circuits built into the ESCs. (NOTE: Our optional custom made 2-conductor 1-to-6 multi-harness is made especially for this ARF with no red wire so you may connect six ESCs to each harness and each harness to a throttle port on your receiver. If you do not use our optional custom made 2-conductor 1-to-6 multi-harness you must ‘open’ the red wire in the throttle lead of each of the twelve electronic speed controls. 3. During early tests we verified the Dornier Do X might fly on only 10 motors without nacelles installed (only the motor boxes). However, for safety we strongly recommend using 12 motors with a minimum 25A ESC and 3S LiPo battery for each propeller to minimize the chance of any unexpected major power loss in the air. 4. Based on our extensive testing, the Maxford USA 25A ESCs may be located either under the hatch in the nose (close to the batteries for shorter battery wires) or inside the motor boxes (close to the motors for better cooling). This ARF comes pre-wired for locating the ESCs in the nacelles for better cooling. If you prefer to locate the ESCs in the nose you could add one more wire into the wing’s center section. If you do so, we recommend using 16 AWG silicon wire. 5. Placing the LiPo flight batteries in the forward section of the fuselage under the nose hatch simplifies removal of the batteries for recharging. The overall flying weight is also reduced since carrying the batteries in the nose means little or no extra weight is needed to balance at the recommended CG. 6. We recommend using 12 stand-alone power systems for this ARF. However, to reduce the number of batteries to plug in before and after each flight, the customer has the option to use 2 or 4 LiPo batteries with mAh and C ratings high enough to supply power to 6 or 3 of the motors at the same time. However, using 2 or 4 LiPo battery packs increases the flying risk: if any battery has a problem, you will lose all 3 or 6 motors attached to that battery at the same time. V. STORAGE, FIELD SETUP & PREFLIGHT CHECKS 1. Check the Mylar covering material’s joints and surfaces. If necessary, carefully use an iron on medium heat to secure the edges and to tighten any loosened areas. Recheck and retighten from time to time; be careful to not apply too much heat as you secure edges or tighten the Mylar. If any trim becomes loosened, press it down and/or apply clear tape. Never apply heat to any trim, insignia, marking or plastic part. (NOTE: A conservative modeler may wish to carefully apply a thin coat of epoxy to seal all seams to help protect against water leakage. Do not apply excess heat at the seams where you have applied epoxy to the Mylar covering material.) 2. Ensure the propellers are securely attached to your motors and that they remain undamaged and correctly balanced. 3. As with all radio-controlled model airplanes, your Dornier Do X must pass the radio-range ground check recommended by your radio’s manufacturer or you may not fly safely. 4. To remove the outer wing panels: a. Remove and set aside the bolt that secures each wing panel to the wing’s center section. Slide the wing panels approx. 2-inches away from the wing’s center section, disconnect the aileron servo extensions, then slide the wing panels away from the wing’s center section and off the wing rod. The wing rod may also be removed from the wing’s center section if desired for transport or storage. Carefully secure the removed screw(s), optional Maxford USA servo-extension safety clips if installed, and wing rod. b. Reverse the above procedure to reattach the wing panels. As each wing panel nears the wing’s center section, reconnect the aileron servo extensions and optional Maxford USA servo-extension safety clips, guide the alignment pins into their openings in the outer ribs of the wing’s center section, slide the tab into its slot, and insert and secure the bolt through the mounting tab and into the blind nut inside the wing’s center section.

Copyright 2016 Page 4 of 14 S161222 5. To remove the wing’s center section (or the entire wing): a. Remove and set aside the six screws that attach the struts to the bottom of the wing’s center section and the two bolts that secure the wing’s center section to the fuselage. Slide the wing’s center section backward, toward the tail, approx. 3-inches, raise the trailing edge of the wing above the wing saddle and disconnect the aileron servo and throttle extensions from your receiver. Carefully lift the wing free of the fuselage and safely secure all removed screws. b. To reattach the wing to the fuselage, position the wing center section above the wing saddle and carefully reconnect the aileron servo and throttle extensions to the correct ports on your receiver. Guide the wing center section’s leading-edge mounting pins into their openings in the fuselage former at the front of the wing saddle, then reinstall and snugly tighten the two wing mounting bolts and reattach the struts to the bottom of the wing’s center section with the supplied wood screws. 6. Preflight checks: a. If any weight was added in the nose or tail to adjust the CG, ensure it remains secure. b. Double check the security of the motor-mounting boxes, motors and nacelle covers. c. Make certain all screws, clevises and other mechanical and electrical connections are secure. d. Double-check all control directions and the amounts of control throws. e. Double- or even triple-check all connections. Do not attempt to fly with a damaged or frayed connection or wire. f. As with all radio-controlled model airplanes, this model must pass the radio range ground check recommended by your radio’s manufacturer or you may not fly safely. g. We suggest you make it a habit to set your transmitter’s throttle control safely to minimum before turning ON your transmitter and receiver and connecting your flight batteries. Carefully setup and operate your radio-control and power systems according to the manufacturer’s instructions and follow the guidelines and hints offered by the Academy of Model Aeronautics, your local R/C club, and concerned manufacturers, all wishing to help ensure your safe enjoyment of this hobby.

Recheck the operation of this model airplane before every flight to ensure that all equipment is still operating correctly and that the model remains structurally sound. Before every flight, check all electrical, control and structural connections; do not fly without replacing any that you find damaged or worn. 7. Before you begin assembly of this model airplane, study all the instructions and test-fit each part to ensure you fully understand the instructions and that no parts are missing, damaged or unsatisfactory. Temperature and/or humidity differences between the factory, our warehouse and your home or workshop may dictate the need for slight adjustments to some mounting surfaces to ensure proper alignment; we recommend you contact us before attempting any such adjustments. 8. To help ensure the security of your servo connections, we recommend using optional Maxford USA servo-extension safety clips as pictured at the right. (For information about safety clips see http://www.maxfordusa.com/servoextensionsafetyclip.aspx.) 9. Assemble any included or optionally installed EZ-Link connectors as shown at the far right. Clamping bolt When applying threadlock compound, do NOT Connector body glue the EZ-Link connector to the control arm Control arm (or tab) or mounting tab. Also be careful to not let the Washer pushrod bind against nearby surface. Mounting nut 10. Use your radio or a servo tester to center your servos before installation. (You may be interested to learn more about servo testers at http://www.maxfordusa.com/servo.aspx.) 11. String may be supplied to pull your servo’s leads and/or servo extensions through the wing; however, you may find it easier to use masking tape to temporarily attach the connector to the end of a length of coat hanger wire, then use the wire to pull the lead through the airframe as shown at the right. 12. After you determine each wood-screw’s location, drill a small guide hole and apply thin CA adhesive to harden and strengthen the wood where the screws are to be installed. 13. If Mylar hides a CA hinge’s slot, find and open the slot by carefully pressing with a fingernail or sharp hobby knife. 14. If you are not an experienced ARF assembler or R/C pilot, we strongly urge you to get assistance from an experienced R/C assembler and pilot. 15. Apply threadlock compound or CA adhesive to secure hardware from vibration. 16. Use epoxy to permanently attach and reinforce critical airframe assemblies. 17. If you have concern about the security of any factory fabrication procedure(s), you may apply extra epoxy adhesive around the perimeter of such part(s) as a safety precaution. 18. Production details (such as included hardware items and/or Mylar or paint colors) may vary. 19. After adjusting a clevis, secure the clevis to its threaded rod with threadlock compound, epoxy, or CA adhesive. For additional safety, you may hold the clevis closed by adding a small piece of tubing (not supplied) as shown at the right. (NOTE: If included with this model, clevises may be made of plastic or metal.) 20. Since this model includes some plastic, fiberglass and/or carbon-fiber-reinforced parts, be reminded that if you ever drill, grind or sand any such part, wear safety goggles, a particle mask and rubber gloves to guard yourself from eye, skin and respiratory-tract irritation; never blow into such a part as the dust may blow back into your face. 21. Periodically check the Mylar covering material’s joints and surfaces; if necessary, carefully use an iron (do NOT set the iron’s temperature too high) to secure the edges and to tighten any loosened areas. 22. Our extensive testing has shown the recommended Maxford USA Uranus 28309 motors and Uranus 25A ESCs may be installed in the Dornier Do X’s nacelles with the LiPo flight batteries mounted in the nose. With this one exception, we recommend that you carefully read and consider the full text of the remaining “IMPORTANT THINGS TO CONSIDER WHEN INSTALLING AND OPERATING YOUR MODEL AIRPLANE’S ELECTRIC POWER SYSTEM” on the Maxford USA Website at Copyright 2016 Page 6 of 14 S161222 http://www.maxfordusa.com/brushlessmotorandcontroller.aspx and any instructions that may be included with your motors, electronic speed controls, batteries and charger.

IX. INITIAL SETUP & ADJUSTMENTS 1. Center of gravity (CG): For your initial flight we recommend the Dornier Do X should balance when lifted at a point approx. 4 5/8 to 5 1/4-inches (about 12 to 13 cm) behind the leading edge of the wing. When correctly balanced, it should hang level, neither nose up nor nose down. 2. Recommended initial deflections: Initial control surface throws for your first flights: Recommended Initial Deflections Ailerons ...... 3/4-inch (15 degrees) at the trailing edge, up and down from center.

Elevators ...... 3/4-inch (18 degrees) at the trailing edge, up and down from center. Rudder ...... 1-inch (18 degrees) at the trailing edge, left and right from center.

If you like to mix rudder with your ailerons, we recommend an aileron-to-rudder mix of around 50%.
