INTRODUCTION

Thank you for choosing the Global Fokker D-VII ARF and welcome to the exciting world of WWI R/C airplanes! W e are sure that you will appreciate the high quality , easy assembly and excellent flight characteristics of the Fokker D-VII ARF.

The full size Fokker D-VII was a single seat fighter that featured fabric-covered wings with plywood ribs and plywood leading edges. The fuselage was wire-braced steel tubing, completely fabric-covered except for the cowling, which was sheet steel. The two most successful engines used in the Fokker D-VII were the Mercedes 160 H.P. and the BMW 185 H.P. engines. The Fokker D-VII, designed by Reinhold Platz, was a clean, simple-looking biplane, equipped with two Maxim 08/15 7.92mm machine guns.

The Fokker D-VIIs were so successful that, in August of 1918 alone, they shot down 565 Allied aircraft. One thing that made the Fokker D-VII such a formidable opponent was the fact that it could hang 45 degrees on its prop and shoot without stalling. By doing this, the Fokker D-VII could fly up under the bellies of enemy aircraft and shoot them down. The Fokker D-VII could climb 5000 meters in 16 minutes, fly at a ceiling of 19,685 feet, and had an insurance of 90 minutes. The aircraft had an approximate top speed of 124 mph.

Now you too can feel what that was like with your own Stand-Off Scale R/C model of the Fokker D-VII. When you open up the box, you'll notice that you won't have much left to do or to purchase to finish your new airplane. The Fokker D-VII is a complete kit. Wire Spoke wheels, fuel tank, pushrods, clevises and other hardware are all included. The airframe is completely prebuilt and covered by master craftsmen, who take their time to ensure that every part is straight and properly glued.

A NOTE ABOUT COVERING

The covering material used on the Fokker D-VII is a heat shrink polyester material. Because of this, it is possible with heat and humidity changes that the covering on your airplane may wrinkle or sag. This trait is inherent in all types of heat shrink material. T o remove the wrinkles you will need to purchase, or borrow from a fellow modeler, a heat iron. If you need to purchase one, the Global Sealing Iron # 360900 is recommended.

Follow these simple steps to remove the wrinkles:

❑ 1) Plug in and turn on the sealing iron to the medium temperature setting. Allow the iron to heat up for approximately 5 - 7 minutes.

❑ 2) After the iron has reached temperature, lightly apply the iron to the wrinkled section of the covering. Move the iron slowly over the wrinkled section until the covering tightens and the wrinkles disappear. You will notice that the color of the covering will darken when it is heated. When the covering cools back down, it will return to its normal color.

If the color layer smears from any of the seams, the temperature of the iron is too hot. Turn the tempera-

☛

ture dial down and wait about 5 minutes for the iron to adjust to the lower temperature. You can remove any excess color streaks using a paper towel soaked with a small quantity of acetone.

BOTTOM WING ASSEMBLY

PARTS REQUIRED

❑ {1} Bottom Wing - Right & Left Halves ❑ {1} Bottom Wing Dihedral Brace (W-26)

TOOLS AND SUPPLIES REQUIRED

❑ Kwik Bond 30 Minute Epoxy ❑ Excel Modeling Knife ❑ Masking Tape ❑ Straight Edge Ruler ❑ Pen or Pencil ❑ 220 Grit Sandpaper w/Sanding Block ❑ Paper Towels ❑ Rubbing Alcohol ❑ NHP Epoxy Mixing Sticks ❑ NHP Epoxy Mixing Cups

INSTALLING THE DIHEDRAL BRACE

❑ 1) Look carefully at the surface of each root rib on both wing halves. Notice how the excess covering material overlaps onto them. Using a modeling knife, carefully trim and remove the excess from both of the root ribs, leaving about 1/16" of covering material overlapping so it does not pull away later.

❑ 2) Using a straight edge ruler and a pen, locate and mark the centerline of the plywood dihedral brace (W-26). Draw one vertical line, on each side of the brace, at this location. See photo # 1 below.

Photo # 1

❑ 3) Test fit the plywood dihedral brace into the plywood dihedral brace box in each wing half. The brace should slide into each wing half up to its centerline. If it does not, remove the brace and lightly sand the edges and tips until the proper fit is obtained.

See photo # 2 below.

root ribs will expose more of the wood. This will result in a stronger joint when the wing halves are epoxied together later.

The dihedral brace is cut in the shape of a "V".

☛

The "V" shape should face the top surface of the wing when the brace is installed.

❑ 4) T est fit both of the wing halves together with the dihedral brace temporarily installed (without using glue). Look carefully at the center section joint: the wing halves should fit together tightly with few or no gaps in the joint. See photo # 3 below.

Photo # 3

❑ 10) Mix a generous amount of Kwik Bond 30 Minute Epoxy. Apply a thin layer of epoxy to the exposed half of the dihedral brace, the inside of the second wing half, and the entire surface of both root ribs. Make sure to use enough epoxy to fill any gaps.

❑ 11) Slide the two wing halves together and carefully align them at both the leading and trailing edges. Wipe away any excess epoxy, using a paper towel and rubbing alcohol, and use several pieces of masking tape to hold the two wing halves aligned until the epoxy fully cures.

❑ 12) Once the epoxy has fully cured, doublecheck the center section joint. If any gaps are present, mix a small amount of Kwik Bond 30 Minute Epoxy and carefully fill any remaining gaps. Remove any excess epoxy using a paper towel and rubbing alcohol, and allow the epoxy to thoroughly cure.

❑ 5) If the center section joint is not tight, remove the wing halves and the dihedral brace, and lightly sand the edges and tips of the brace. T est fit the wing halves together with the dihedral brace installed again and repeat until you are satisfied with the fit. Once you are satisfied with the fit, remove the wing halves and the dihedral brace.

properly. The better the fit, the stronger the center section joint will be.

❑ 6) Following the instructions on the packaging, mix a generous amount of Kwik Bond 30 Minute Epoxy. Mix the epoxy for about 1 minute. This will ensure that both parts are thoroughly incorporated.

❑ 7) Working with only one wing half for now, apply a thin layer of epoxy inside the plywood dihedral brace box and to only half of the dihedral brace. Make sure to cover the top and bottom, as well as the sides, and use enough epoxy to fill any gaps.

❑ 8) Slide the dihedral brace into the wing half up to its centerline. Remove any excess epoxy before it dries, using a paper towel and rubbing alcohol. Allow the epoxy to fully cure before proceeding.

❑ 13) Once the epoxy has fully cured, carefully remove the masking tape from the wing.

BOTTOM WING MOUNTING

PARTS REQUIRED

❑ 6) Remove the two ailerons from the wing and set them aside for now.

❑ {1} Wing Bolt Doubler (W-30) ❑ {2} 4mm x 25mm Machine Screws ❑ {2} 4mm Flat Washers ❑ {2} 4mm Blind Nuts

TOOLS AND SUPPLIES REQUIRED

❑ Kwik Bond Thick C/A ❑ Excel Modeling Knife ❑ Ernst Airplane Stand ❑ Masking Tape ❑ Electric Drill ❑ 5/32" & 7/32" Drill Bits ❑ Straight Edge Ruler ❑ Phillips Head Screwdriver ❑ Needle Nose Pliers ❑ Pen or Pencil

ALIGNING THE WING

❑ 1) Set the fuselage upside down in your airplane stand and place the bottom wing into the wing saddle. Align the two hardwood dowels in the leading edge of the wing with the two predrilled holes in the fuselage's forward bulkhead.

❑ 2) Carefully slide the wing forward, making sure that the two hardwood dowels fully engage the two predrilled holes in the forward bulkhead.

❑ 3) Using a ruler and a pen, locate the centerline of the fuselage, at the back edge of the wing saddle, and place a mark. See photo # 6 below.

❑ 7) Check that the wing is square to the fuselage. To do this use a ruler and carefully measure from the trailing edge of each wing tip to the back edge of the fuselage. Both of these measurements should be the same. See figure # 1 below.

Figure # 1

A = A-1

❑ 8) If the two measurements are not the same, carefully lift the masking tape and adjust the back of the wing until they are. When you are satisfied with the alignment, reattach the masking tape to hold the wing securely in place.

INSTALLING THE BLIND NUTS

❑ 9) Using a ruler and a pen, measure 3/8" in front of the trailing edge of the wing and place two marks, one on each side of the centerline. Now measure 1-9/32" out from each side of the centerline and place two marks. See photo # 7 below.

Photo # 7

Photo # 6

❑ 4) The joint where the two wing halves were glued together is the centerline of the wing. Align the centerline of the wing with the centerline you drew on the bottom of the fuselage.

❑ 5) While holding the wing in alignment, use a couple of pieces of masking tape to hold the wing securely to the fuselage.

❑ 10) Using a drill with a 5/32" drill bit, carefully drill two holes into the wing and down through the plywood wing hold down block inside the fuselage.

Angle the drill bit so that the holes will be per-

☛

pendicular to the bottom of the wing. ❑ 11) Remove the wing from the wing saddle.

Using a drill with a 7/32" drill bit, enlarge only the two holes in the plywood mounting block.

❑ 12) Install the two 4mm blind nuts into the bottom of the plywood mounting plate. Use a pair of needle nose pliers to squeeze the blind nuts up into place. See photo # 8 below.

A balsa filler block has been preinstalled onto

☛

the bottom of the plywood plate to make it easier to install the blind nuts.

❑ 18) Apply a generous amount of Kwik Bond Thick C/A to the bottom of the doubler. Set the doubler back into place and realign it. Hold the doubler firmly in place until the C/A fully cures.

❑ 19) Remove the wing from the wing saddle. Using a drill with a 5/32" drill bit, drill the two wing mounting screw holes through the wing bolt doubler. Use the holes you drilled through the wing as a guide.

MOUNTING THE WING

❑ 20) Place the wing back into the wing saddle and bolt it in place using the two 4mm x 25mm machine screws and two 4mm flat washers. Tighten the screws firmly using a phillips head screwdriver. See

photo # 10 below.

❑ 13) With the blind nuts fully seated, carefully apply a bead of Kwik Bond Thick C/A around the bottom of each blind nut to lock them into place. Be careful not to get any glue into the threads and allow the C/A to fully cure before proceeding.

INSTALLING THE WING BOLT DOUBLER

❑ 14) Place the wing back into the wing saddle and realign it. Use a couple of pieces of masking tape to hold it in place.

❑ 15) Set the wing bolt doubler (W-30) in place on the bottom of the wing. The back edge of the doubler should be about 1/16" in front of the trailing edge and the sides of the doubler should be even with the sides of the fuselage. See photo # 9 below.

❑ 8) When you are satisfied with the alignment, hold the stabilizer firmly in place using a couple of pieces of masking tape. Do not use glue yet!

MOUNTING THE STABILIZER

❑ 9) With the stabilizer held firmly in place, use a pen to draw lines onto the bottom of the stabilizer where it and the fuselage sides meet. Do this on both the right and left sides.

❑ 10) Remove the stabilizer from the fuselage. Using the lines you just drew as a guide, carefully remove the covering from between them using a modeling knife. See photo # 12 below.

❑ 6) With the stabilizer in place, look carefully from the front of the fuselage at both the wing and the stabilizer. When aligned properly, the stabilizer should be level with the wing. If it is not level, use 220 grit sandpaper and a sanding block to sand down the higher stabilizer mounting side until the correct alignment is achieved. See figure # 2 below.

it, cut with only enough pressure to cut through only the covering itself. Cutting into the balsa will weaken the stabilizer.

❑ 11) Mix a generous amount of Kwik Bond 30 Minute Epoxy. Apply a thin layer to the mounting area on the bottom of the stabilizer and to the tops of the stabilizer mounting sides and cross-member on the fuselage.

❑ 12) Set the stabilizer back into place and realign it, double checking all of your measurements once more. When satisfied with the alignment, hold the stabilizer in place using several pieces of masking tape and remove any excess epoxy using a paper towel and rubbing alcohol before it cures. Allow the epoxy to fully cure before proceeding.

ALIGNING THE STABILIZER

❑ 1) Remove the rudder and the hinges from the stabilizer and set them aside for now.

❑ 2) Using a modeling knife, remove the covering from over the top of the precut slot in the horizontal stabilizer.

❑ 3) Set the vertical stabilizer in place, making sure that the tab in the bottom of the stabilizer is pushed down firmly into the precut slot. The front of the stabilizer should also be lined up with the centerline you drew previously on the horizontal stabilizer.

MOUNTING THE STABILIZER

❑ 4) While holding the vertical stabilizer firmly in place, use a pen to draw a line on each side of it where it meets the top of the horizontal stabilizer. Also draw a line on top of the horizontal stabilizer around the base of the vertical stabilizer.

❑ 5) Remove the stabilizer. Using a modeling knife, carefully remove the covering from below the

❑ 7) Mix a generous amount of Kwik Bond 30 Minute Epoxy. Apply a thin layer to the mounting slot in the horizontal stabilizer and to the sides and bottom of the vertical stabilizer mounting area. Also apply epoxy to the top of the horizontal stabilizer.

❑ 8) Set the stabilizer back into place and realign it, double checking all of your measurements. Hold the stabilizer in place using several pieces of masking tape and remove any excess epoxy using a paper towel and rubbing alcohol. Allow the epoxy to fully cure before proceeding.

INSTALLING THE TRIANGLE STOCK

❑ 9) Using a modeling knife, remove the covering that overlaps onto the inner edges of the two pieces of precovered triangle stock.
