Beautifully detailed and expertly built, the WattAge P-47 Thunderbolt EP ARF will impress with its fully-rounded scale fuselage,
panel lines and detailed finish. The model is "Almost Ready-to-Fly", so the building, covering and painting have already been
done for you. The airplane features a scale molded fuselage with strategically placed light-plywood formers for strength and
weight savings. The wing and tail surfaces are built-up balsa and all parts are laser cut, resulting in superior fit and alignment.
Small touches that add to the scale realism of your new P-47 Thunderbolt EP ARF include a molded dummy radial engine, landing
gear strut covers and radiator scoop. Also included is a generous hardware package - lightweight foam wheels, prebent tail wheel
assembly, pushrods, control horns and clevises, and more! Just finish the assembly, install your radio gear, motor, battery and
ESC, and you're ready to fly sorties over your favorite flying field!

  • Page 9 IMPORTANT The wing joiner is cut in a shallow "V" shape. When you test-fit the wing joiner in the next procedure, make sure that the "V" shape is toward the TOP of the wing panels. Test-fit the wing joiner into each wing panel. It should slide easily into each wing panel, up to the centerline you drew.

  • Page 10: Section 7: Wing Mounting And Belly Pan Installation

    Mix a generous amount of 5 minute epoxy and apply a thin layer to the exposed half of the wing joiner, the inside of the wing joiner box in the second wing panel, and the entire surface of BOTH root ribs. Make sure to use enough epoxy to fill any gaps. IMPORTANT It is of the utmost importance to the integrity of the wing center-section joint that you apply a generous amount of epoxy to both root ribs and the wing joiner.
  • Page 11 STEP 2: ALIGNING THE BELLY PAN Cut a hole in the bottom of the belly pan to access the wing hold- down screw. Position the hole on the centerline of the belly pan, 5/8" in front of the back edge. With the wing installed onto the fuselage, position the belly pan onto the wing.

  • Page 12: Section 8: Stabilizer Installation

    SECTION 8: STABILIZER INSTALLATION YOU'LL NEED THE FOLLOWING PARTS FROM THE KIT: (1) Vertical Stabilizer w/Rudder (1) Horizontal Stabilizer w/Elevator Halves YOU'LL NEED THE FOLLOWING TOOLS AND SUPPLIES: Kwik Bond 5 Minute Epoxy Masking Tape Excel Modeling Knife Paper Towels Ruler Rubbing Alcohol Pencil...
  • Page 13 When you are satisfied that the stabilizer is square to the wing, draw a couple of marks on each side of the front of the stabilizer where it and the fuselage sides meet, then use a couple of small pieces of masking tape to hold the stabilizer firmly in place and aligned.

  • Page 14: Section 9: Control Surface Hinging

    Use the hinges supplied in the hardware bag to hinge the control surfaces. The P-47 Thunderbolt EP ARF uses C/A-style hinges to hinge the control surfaces. These hinges are designed to be glued into place using thin C/A. Do not glue these hinges into place using any other type of glue, such as thick C/A or epoxy. Use of any adhesive other than thin C/A could result in failure of the hinges during flight.
  • Page 15 Push one T-Pin through the center of three C/A-style aileron hinges, as shown. The T-Pin will keep the hinges centered while you are hinging the aileron. Slide one hinge into each hinge slot in one aileron, making sure that you push each hinge in up to the T-Pin. Don't glue the hinges into the aileron yet.

  • Page 16: Section 10: Aileron Control System Installation

    STEP 3: INSTALLING THE TAIL WHEEL ASSEMBLY Measure 3/4" up from the bottom of the rudder (at the leading edge) and drill a 1/16" diameter hole for the tail wheel wire. IMPORTANT Make sure to drill the hole perpendicular to the leading edge and be careful not to drill out through the sides of the rudder.
  • Page 17 STEP 1: INSTALLING THE AILERON SERVOS Install the rubber grommets and brass collets onto one aileron servo, making sure to install the collets with the flanges toward the bottom of the servo, then plug a 12" servo extension lead to the servo lead. Pull the servo lead through the wing and out the hole in the top of the wing, using the piece of string that's installed in the wing.

  • Page 18: Section 11: Elevator And Rudder Control Systems Installation

    Install the control horn and backplate, using two M2 x 14mm machine screws, being careful not to overtighten them. Thread one nylon clevis onto the pushrod wire and snap the clevis into the outermost hole in the control horn. Hold the pushrod wire with a pair of pliers to prevent it from turning or twisting when installing the clevis.
  • Page 19 Position one nylon control horn onto the bottom of one elevator half, then mark the locations of the mounting holes. When aligned properly, the centerline of the control horn should be 7/8" out from the inside edge of the elevator half (at the hinge line) and the clevis attachment holes should be lined up over the hinge line.
  • Page 20 Slide the adjustable servo connector/servo horn assembly over the plain end of the pushrod wire, then attach the servo horn to the servo, making sure that the servo horn is centered and points toward the middle of the fuselage. Double-check that both elevator halves are centered, then carefully install and tighten the machine screw in the top of the adjustable servo connector to secure the elevator pushrod wire into place.

  • Page 21: Section 12: Motor And Cowling Installation

    Remove the masking tape from the rudder and double-check that the servo horn and rudder are still centered. If the rudder is not centered, adjust the clevis until it is. Move the rudder right and left several times to ensure that the linkage assembly does not bind. It should operate smoothly in both directions.
  • Page 22 Install the propeller adapter onto your motor. So that the dummy radial engine and the cowling will line up with the spinner backplate when it's installed later, the front of the propeller adapter should be 3/4" in front of the motor plate. STEP 1B: INSTALLING A BRUSHLESS OUTRUNNER MOTOR Slide the motor into position and line up the holes in the front of the motor with the matching holes in the motor plate.
  • Page 23 STEP 3: INSTALLING THE COWLING IMPORTANT Before lining up the cowling and drilling the pilot holes for the cowling mounting screws in the next few procedures, look carefully at the inside of the cowling mounting flange on the fuselage. You will notice three reinforced cowling mounting positions - one at the top and one at both the 4 o'clock and the 8 o'clock positions.

  • Page 24: Section 13: Landing Gear Installation

    SECTION 13: LANDING GEAR INSTALLATION YOU'LL NEED THE FOLLOWING PARTS FROM THE KIT: (2) Prebent Landing Gear Wires (4) M2 x 8mm Wood Screws (2) Main Gear Wheels (2) Wheel Collars w/Grub Screws (2) Plastic Landing Gear Strut Covers (2) U-Shaped Plastic Straps (2) Nylon Mounting Straps YOU'LL NEED THE FOLLOWING TOOLS AND SUPPLIES: Kwik Bond Thick C/A...

  • Page 25: Section 14: Final Assembly

    Cut one U-Shaped plastic strap in half so that you have two separate straps. Working with one landing gear strut cover, line up the strut cover on the outside of the landing gear wire, then carefully glue the two plastic straps over the landing gear wire and to the strut cover, to secure the strut cover into place.
  • Page 26 STEP 2: INSTALLING THE ELECTRONIC SPEED CONTROL Connect your ESC to your motor, being careful that the polarity is correct. Make sure to use heat-shrink tubing to insulate any solder joints that you make. Mount your ESC to the side of the fuselage, in front of the forward bulkhead, using a piece of double-sided foam tape (not included).

  • Page 27: Section 15: Balancing The P-47 Thunderbolt Ep Arf

    3" (76mm). IMPORTANT Balance the P-47 Thunderbolt EP ARF with the battery installed and the airplane fully assembled. Install the wing onto the fuselage. Apply two short pieces of masking tape onto the top of the wing, 2-3/4" (70mm) back from the leading edge, measured at the fuselage sides.

  • Page 28: Section 17: Preflight Check And Safety

    SECTION 17: PREFLIGHT CHECK AND SAFETY Check the operation of the throttle. To do this, do the following: A) Plug the flight battery into the ESC and turn on the radio system.
