P-47 THUNDERBOLT 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. P47 - THUNDERBOLT. 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. Important: before you start construction Even if you have already 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. 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 warp: Hold the panel twisted gently in the opposite direction to the warp, and apply warm air to remove the creases from the covering. Caution! do not heat the film more than is absolutely 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. 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. 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.

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. It should not touch the top of the tank. Tygon gas tubing not included. FUEL TANK. INSTALLING THE ST OPPER 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. 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. Vent tube Fuel pick- up tube Fuel fill tube 5) Test fit the stopper assembly into the tank. It may be necessary to remove some of the flashing around the tank opening using a modeling knife. If flashing is present, make sure none of it falls into the tank. 6) When satisfied with the alignment of the stopper assembly tighten the 3mm x 20mm machine screw until the rubber stopper expands and seals the tank opening. Do not over tighten the assembly as this could cause the tank to split. 7) Using a modeling knife, cut 3 lengths of fuel line 150mm long. Connect 2 lines to the 2 vent tubes and 1 line to the fuel pickup tube in the stopper. 15 P47 - THUNDERBOLT.

BALANCING. 1) It is critical that your airplane be balanced correctly. Improper balance will cause your plane to lose control and crash. THE CENTER OF GRA VITY IS LOCA TED 90mm BACK FROM THE LEADING EDGE OF THE WING, AT THE FUSELAGE. 2) Mount the wing to the fuselage. Using a couple of pieces of masking tape, place them on the top side of the wing 90 mm back from the leading edge, at the fuselage sides. Accurately mark the balance point on the top of the wing on both sides of the fuselage. The balance point is located90 mm 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 . 3. Turn the airplane up side down. Place your fingers on the masking tape and carefully lift the plane . 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. 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. 26 INSTRUCTION MANUAL. 1) We highly recommend setting up a plane using the control throws listed. 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.
