SUGGESTION To avoid scratching your new airplane, do not unwrap the pieces until they are needed for assembly. Cover your workbench with an old towel or brown paper, both to protect the aircraft and to protect the table. Keep a couple of jars or bowls handy to hold the small parts after you open the bag. NOTE Please trial fit all the parts. Make sure you have the correct parts and that they fit and are aligned properly before gluing! This will assure proper assembly. SEA FURY ARF is hand made from natural materials, every plane is unique and minor adjustments may have to be made. However, you should find the fit superior and assembly simple. The painted and plastic parts used in this kit are fuel proof. However, they are not tolerant of many harsh chemicals including the following: paint thinner, C/A glue accelerator, C/A glue debonder and acetone. Do not let these chemicals come in contact with the colors on the covering and the plastic parts. SEA FURY Item code: BH148. Instruction Manual Caution: This model is not a toy! If you are a beginner to this type of powered model, please ask an experienced model flyer for help and support. If you attempt to operate the model without knowing what you are doing you could easily injure yourself or somebody else. Please keep your safety and well-being in mind at all times. necessary. If the air or the iron is too hot, the film may melt and holes may be formed. This model is highly pre-fabricated and can be built in a very short time. However, the work which you have to carry out is important and must be done carefully. The model will only be strong and fly well if you complete your tasks competently - so please work slowly and accurately. Important: Before you start construction Even if you have built a large number of RC models please read right through these instructions and check all the kit components against the parts list. We have taken great trouble to keep construction as simple as possible, without making any compromises in the area of safety. When self-tapping screws have to be screwed into wood, apply a little white glue to prevent them shaking loose: just squirt white glue into the hole and fit the screw. Note regarding the film covering Minor creases or bubbles may develop in the film covering due to major fluctuations in weather conditions (temperature, humidity etc.); in rare cases you may even find a slight warp in a component. These minor faults are in the nature of film-covered built-up wooden structures, and can easily be corrected using a heat gun, as commonly used for modelling. Creases: Blow warm air over the area and rub down with a soft cloth. Wing wrap: Hold the panel twisted gently in the opposite direction to the wrap,and apply warm air to remove the creases from the covering. Caution! do not heat the film more than is absolutely SAFETY PRECAUTION + This is not a toy. + Be sure that no other flyers are using your radio frequency. + Do not smoke near fuel. + Store fuel in a cool, dry place, away from children and pets. + Wear safety glasses. +The glow plug clip must be securely attached to the glow plug. + Do not flip the propeller with your fingers. + Keep loose clothing and wires away from the propeller. + Do not start the engine if people are near. Do not stand in line with the side of the propeller. + Make engine adjustments from behind the propeller only. Do not reach around the spinning propeller.

VI. fuel tank INSTALLING THE STOPPER ASSEMBLY 1) The stopper has been pre-assembled at the factory. 2) Using a modeling knife, cut one length of silicon fuel line (the length of silicon fuel line is calculated by how the weighted clunk should rest about 8mm away from the rear of the tank and move freely inside the tank). Connect one end of the line to the weighted clunk and the other end to the nylon pick up tube in the stopper. 3) Carefully bend the second nylon tube up at a 45 degree angle (using a cigarette lighter). This tube will be the vent tube to the muffler. 8) Feed three lines through the fuel tank compartment and through the pre-drilled hole in the firewall. Pull the lines out from behind the engine, while guiding the fuel tank into place. Push the fuel tank as far forward as possible, the front of the tank should just about touch the back of the firewall. Blow through one of the lines to ensure the fuel lines have not become kinked inside the fuel tank compartment. Air should flow through easily. 9) To secure the fuel tank in place, apply a bead of silicon sealer to the forward area of the tank, where it exits the fuselage behind the engine mounting box and to the rear of the tank at the forward bulkhead. Do not secure the tank into place permanently until after balancing the airplane. You may need to remove the tank to mount the battery in the fuel tank compartment. 4) Carefully bend the third nylon tube down at a 45 degree angle (using a cigarette lighter). This tube will be vent tube to the fueling valve. Tie wrap When the stopper assembly is installed in the tank, the top of the vent tube should rest just below the top surface of the tank.

Instruction Manual BALANCING CONTROL THROWS 1) It is critical that your airplane be balanced correctly. Improper balance will cause your plane to lose control and crash. 1) We highly recommend setting up a plane using the control throws listed. THE CENTER OF GRAVITY IS LOCATED 107MM BACK FROM THE LEADING EDGE OF THE WING. 2) Mount the wing to the fuselage. Using a couple of pieces of masking tape, place them on the top side of the wing 107mm back from the leading edge, at the fuselage sides. 3) Turn the airplane upside down. Place your fingers on the masking tape and carefully lift the plane. 2) The control throws should be measured at the widest point of each control surface. 3) Check to be sure the control surfaces move in the correct directions. Control throw Ailerons: Low: 10mm up / downo. High: 12mm up / down. Control throw Flaps: Mid: 16mm down. Accurately mark the balance point on the top of the wing on both sides of the fuselage. The balance point is located 107mm back from the leading edge. This is the balance point at which your model should balance for your first flights. Later, you may wish to experiment by shifting the balance up to 10mm forward or back to change the flying characteristics. Moving the balance forward may improve the smoothness and arrow- like tracking, but it may then require more speed for take off and make it more difficult to slow down for landing. Moving the balance aft makes the model more agile with a lighter and snappier ”feel”. In any case, please start at the location we recommend. Control throw Elevators: Low: 8mm up / down. High: 10mm up / down. With the wing attached to the fuselage, all parts of the model installed ( ready to fly), and empty fuel tanks, hold the model at the marked balance point with the stabilizer level. Flap control Lift the model. If the tail drops when you lift, the model is “tail heavy” and you must add weigh* to the nose. If the nose drops, it is “nose heavy” and you must add weight* to the tail to balance. *If possible, first attempt to balance the model by changing the position of the receiver battery and receiver. If you are unable to obtain good balance by doing so, then it will be necessary to add weight to the nose or tail to achieve the proper balance point. Control throw Rudder: Low: 20mm left / right. High: 22mm left / right. 10mm Aileron control 10mm 16mm 8mm Elevator control 8mm 20mm Rudder control 20mm PRE-FLIGHT CHECK 1) Completely charge your transmitter and receiver batteries before your first day of flying. 2) Check every bolt and every glue joint in your plane to ensure that everything is tight and well bonded. CG 107mm 3) Double check the balance of the airplane. 4) Check the control surface. 5) Check the receiver antenna. It should be fully extended and not coiled up inside the fuselage. 6) Properly balance the propeller. We wish you many safe and enjoyable flights with your SEA FURY. 15 SEA FURY Item code: BH148.
