Thank you for purchasing the Great Planes F okk er Dr. I ARF.
The original Fokker Dr. I was designed in 1915 by Anthony
Fokker. He wanted an aircraft that could out-maneuver any
other fighter of the day and to do so he knew he needed
maximum lift with minimum weight. To accomplish this he
designed an airplane with three wings and an auxiliary fourth
wing on the landing gear with a total empty weight of 827 lb
(376 kg).Because of the sturdiness of the three-wing design,
flying wires were eliminated with the exception of the aileron
control wires that run from the fuselage up to the top wing.
The Fokker Dr. I could turn so sharply that if forced, it could
cause a blackout to the pilots at the controls. The rate of
climb was nearly 2,000 fpm (10.2 m/s) with a service ceiling
of 18,000 feet (5,487 m).Top speed was 97 mph (155 kph)
while stall speed was 30mph (48 kph).

Perhaps the most famous pilot to fly this aircraft was Manfred
Von Richthofen, otherwise known as the Red Baron. He
regularly flew at least four different triplanes and while all of
them had a dark red base color, they all had slightly different
trim schemes. The aircraft Great Planes chose to model was
the one with the serial number FI 102/17, which is the one the
Red Baron used when he was visiting other wings under his
command or when he was visiting the Fokker factory.

The full-size Fokker Dr. I had a total wingspan of 23 ft, 7 in
(7.2 m).The Great Planes model has a total wingspan of 60­1/4" (1524 mm).This wingspan makes this model eligible to
participate in IMAA events.The scale of the model is 1: 4.7.

For the latest technical updates or manual corrections for
the Great Planes Fokker Dr. I ARF, visit the web site listed
below and select the Great Planes Fokker Dr. I ARF. If there
is new technical information or changes to this kit, a “tech
notice” box will appear in the upper left corner of the page.

http://www.greatplanes.com/airplanes/index.html

1.Your Fokker Dr .I should not be considered a toy , b ut rather
a sophisticated, working model that functions very much like
a full-size airplane. Because of its performance capabilities,
the Fokker Dr. I, if not assembled and operated correctly,
could possibly cause injury to yourself or spectators and
damage to property.

2.You must assemble the model according to the instructions.
Do not alter or modify the model, as doing so may result in an
unsafe or unflyable model. In a few cases the instructions may
differ slightly from the photos. In those instances the written
instructions should be considered as correct.

3.You must take time to build straight, true and strong.

4. You must use an R/C radio system that is in first-class
condition, and a correctly sized engine and components
(fuel tank, wheels, etc.) throughout the building process.

5.You must correctly install all R/C and other components so
that the model operates correctly on the ground and in the air .

6.You must check the operation of the model before every
flight to insure that all equipment is operating and that the
model has remained structurally sound. Be sure to check
clevises or other connectors often and replace them if they
show any signs of wear or fatigue.

7. If you are not already an experienced R/C pilot, you
should fly the model only with the help of a competent,
experienced R/C pilot.

8. While this kit has been flight tested to exceed normal use,
if the plane will be used for extremely high stress flying, such
as dogfighting, the modeler is responsible for taking steps to
reinforce the high stress points.

Remember:T ake your time and f ollow the instructions to
end up with a well-built model that is straight and true.

If you have not flo wn this type of model before , we recommend
that you get the assistance of an experienced pilot in your R/C
club for your first flights.If you're not a member of a club, your
local hobby shop has information about clubs in your area
whose membership includes experienced pilots.

In addition to joining an R/C club, we strongly recommend
you join the AMA (Academy of Model Aeronautics). AMA
membership is required to fly at AMA sanctioned clubs.There
are over 2,500 AMA chartered clubs across the country.
Among other benefits, the AMA provides insurance to its
members who fly at sanctioned sites and events .Additionally,
training programs and instructors are available at AMA club
sites to help you get started the right way. Contact the AMA

The Great Planes Fokker Dr. I ARF is an excellent sport-scale
model.Though it is not par ticularly large, its 60-1/4" wingspan
makes it eligible to fly in IMAA events.The IMAA (International
Miniature Aircraft Association) is an organization that promotes
non-competitive flying of giant-scale models. If you plan to
attend an IMAA event, contact the IMAA f or a copy of theIMAA

If you plan to use a 2-stroke .46 or .60 size engine, you will
need to use a Pitts style muffler.The B.C .M.(Bisson Custom
Mufflers) #04061 (BISG4061) Pitts muffler or the Slimline
#3217 (SLIG2217) Pitts Style will work well for the O.S. .61
SF, FP and FX. Use the B.C.M. # 04046 (BISG4046) or the
Slimline # 3218 (SLIG2218) for the O .S .46 SF of FX.To use

• There are two types of screws used in this kit:
Sheet metal screws are designated by a number and a

length. For example #6 x 3/4"

This is a number six screw that is 3/4" long.

Machine screws are designated by a number, threads per
inch and a length. (SHCS is just an abbreviation for “Socket
Head Cap Screw” and that is a michine screw with a socket
head.) For example 4-40 x 3/4"

This is a number four screw that is 3/4" long with

forty threads per inch.

• When you see the term

test fit

in the instructions, it
means that you should first position the part on the
assembly without using any glue, then slightly modify or

custom fit

the part as necessar y for the best fit.

• Whenever the term

glue

is written you should rely upon
your experience to decide what type of glue to use.When a
specific type of adhesive works best for that step, the
instructions will make a recommendation.

• Whenever just

epoxy

is specified you may use

either

30-minute (or 45-minute) epoxy or6-minute epoxy. When
30-minute epoxy is specified it is highly recommended that
you use only 30-minute (or 45-minute) epoxy, because you
will need the working time and/or the additional strength.

• Photos and sketches are placed before the step they
refer to. Frequently you can study photos in following steps
to get another view of the same parts.

• The Fokker Dr. I ARF is factory-covered with Top Flite
MonoKote®film. Should repairs ever be required, MonoKote
can be patched with additional MonoKote purchased
separately. MonoKote is packaged in six-foot rolls, but some
hobby shops also sell it by the foot. If only a small piece of
MonoKote is needed for a minor patch, perhaps a fellow
modeler would give you some. MonoKote is applied with a
model airplane covering iron, but in an emergency a regular
iron could be used. A roll of MonoKote includes full
instructions for application.Following are the colors used on
this model and order numbers for six-foot rolls.

❏ 1. If you have not done so already, remove the major

parts of the kit from the box (wings, fuselage, cowl, tail parts,
etc.) and inspect them for damage.If any parts are damaged
or missing, contact Product Support at the address or
telephone listed in the front cover.

❏ 2. Remove the masking tape and separate the ailerons

from the wing and the elevators from the stab. Use a
covering iron with a covering soc k on high heat to tighten the
model's covering if necessary. It is easy to check the wings
for dihedral at this point. Place the wings on a flat surface,
bottom side down. Each wing should lay completely flat. If
your wing does not sit flat, use a heat gun to shrink the
convex side of the wing until the wing flattens. Do not forget
to check all three wings.

❏ 1. Securely hold the Fokker's fuselage up side down.

Find the landing gear slots at the bottom of the airplane, in
between the firewall and the bottom wing's mounting f ormer .
Make a line with a felt-tip marker along the slots as sho wn in
the picture, across the fuselage. Draw a mark on each line
3/4" [19mm] away from the fuselage's edge and then
another mark 1-7/8" [48mm] away from the edge.

❏ 2. Cut the covering along the slot's centerline as shown

above. Iron down the covering into the slot and then fuel
proof the wood exposed with epoxy.

❏ 3. Using the lines as a guide, mark and drill with a 1/16"

[1.6mm] drill bit the holes for each of the landing gear strap
screws.Harden each hole with thin CA.

❏ 4. Use sixteen #2 x 3/8" [9.5mm] screws to install all the

landing gear straps in place, to hold the main landing gear
as shown above. Your Fokker’s landing gear has been
improved from what you see in this picture .It now has cross­bracing and it is pre-painted.

BUILD THE FUSELAGE

PREPARATIONS

7

❏ 5.The scale wheels in this model have been updated and

preassembled, so it won't be necessary to glue the metal
hub to the wheel cover.

❏ 6. Temporarily mount the main wheels on the landing

gear, using two 5/32" [4mm] wheel collars with 6-32 socket
head set screws (one wheel collar is used for each wheel).
File a flat spot for the wheel collar's set screws.

❏ 7. Feel through the MonoKote to find the tailskid slot on

the aft part of the fuselage and cut it away. Use an iron to
seal the edges.

❏ 8. Sand the base of the tailskid to fit the fuselage's

tailskid slot. Once you get a good fit, mix a small amount of
epoxy and glue the tailskid in place as shown above.

Note: During the assemby and installation of the wings on the
fuselage, we will be referring to 90 degree and 60 degree
metal brackets. These brackets are permanently attached to
the wings or fuselage with screws and temporarily attached
(when the airplane is ready to fly) to the wood struts and to the
metal cabanes with socket head cap screws. One of the pre­drilled holes on each of the brackets has 4-40 threads. This
threaded hole is to be used for the socket head cap screws
that hold the wood struts and metal cabanes.The unthreaded
hole is to be used for the permanent sheet metal screws.

❏ 1. Find the bottom wing (the one that has two Maltese

crosses on the bottom surface), two 90 degree brac kets and
two #4 x 3/8" [9.5mm] screws.

❏ 2. There is one 1/16" [1.6mm] hole drilled out on the top

surface of the bottom wing between the tip rib and the
second rib at each end.This is where the 90 degree bracket
is installed. Harden the hole with thin CA. Check the image
shown for bracket orientation. Leave the bracket slightly
loose, as it may need to be adjusted when the wing struts
are installed.You should install a bracket on the left side and
another one on the right side of the wing.

Assemble the Bottom Wing

ASSEMBLE THE WINGS

8

❏ 3. Find four 1/4" x 1-9/16" [6mm x 40mm] wood dowels.

Make a mark on the dowels 1/4" [6.3mm] from the end of
each as shown above.

❏ 4. Mix a small amount of epoxy and drop it into the

bottom wing's dowel holes.Also apply some epoxy on two of
the dowels.Insert the dowels up to the mark you just made,
so that just 1/4" [6.3mm] of each dowel protrudes. Clean up
any excess epoxy.

❏ 5. Feel through the MonoKote on the rear center section

of the wing for the wing bolt holes.Remember that there are
two of them. Remove the MonoKote both at the bottom and
top surfaces of the wing.

❏ 1. Find the mid wing, the only wing that does not have any

markings, four 90° brack ets and four #4 x 3/8" [9.5mm] screws.

❏ 2. There are two 1/16" holes drilled out on the top and

bottom surfaces of the mid wing between the second rib and
the third rib in from the tip. This is where the 90 degree
brackets are installed.Harden the holes with thin CA.Check
the images shown above for the bracket's orientation.Leave
the brackets slightly loose, as they may need to be adjusted
when the wing struts are installed.You should install a total
of four 90 degree brackets, one on the top and one on the
bottom of the wing ends.

❏ 3.Find two 60 degree brackets and tw o #4 x 1/2" [12mm]

screws.There are two 1/16" [1.6mm] holes drilled out on the
top sheeting of the center section. That is where the 60
degree brackets are to be installed. Harden the holes with
thin CA. Check the image shown for the bracket's
orientation. Leave the brackets slightly loose as they may
need some minor adjustments when the wing struts are
installed.Two 60 degree brackets should be installed on the
top center section of the mid wing.

Assemble the Mid Wing

9

❏ 4.Feel through the MonoK ote and find the two pre-drilled

wing dowel holes on the leading edge of the center section
of the mid wing. Cut away the MonoKote.

❏ 5. Using the two remaining 1/4" x 1-9/16" [6mm x 40mm]

wood dowels you marked on step 3 of the previous section.
Mix a small amount of epoxy and drop it into the mid wing's
dowel holes.Also apply some epoxy on the dowels .Insert the
dowels up to the mark you just made, so that just 1/4" [6.3mm]
of each dowel protrudes.Clean up the excess epoxy.

❏ 6.Feel through the MonoKote in the center section of the

wing for the wing bolt holes.Remember that there are two of
them. Remove the MonoKote both at the bottom and top
surface of the wing.

❏ 1. The first steps in the construction of this wing will be

the installation of the ailerons and the aileron servos. The
process described here will explain how to install the right
aileron and the right aileron servo. The process has to be
repeated again to install the left aileron and the left aileron
servo, or you can work on both at the same time.

❏ 2. Locate the top wing and the right aileron.

❏ ❏ 3. Locate the pre-cut hinge slots on the top wing's

trailing edge and the leading edge of the aileron.Drill a 3/32"
[2.4 mm ] hole, 1/2" [12mm] deep in the center of each hinge
slot to allow the CA to “wick” in. Follow-up with a #11 blade
to clean-out the slots. Hint: If you have one, use a high­speed rotary tool to drill the holes.

❏ ❏ 4. Use a shar p #11 blade to cut a strip of covering

from the hinge slots in the wing and aileron.

❏ ❏ 5. Cut four 3/4" x 1" [19mm x 25mm] hinges from the

CA hinge strip. Snip off the cor ners so they go in easier.

❏ ❏ 6. Test fit the ailerons to the wing with the hinges. If

the hinges do not remain centered, stick a pin through the
middle of the hinge to hold it in position.

❏ ❏ 7. Remove any pins you may have inserted into the

hinges. Adjust the aileron so that there is a small gap
between the LE of the aileron and the wing.The gap should
be small – just enough to see light through or to slip apiece
of paper through.

❏ ❏ 8. Apply six drops of thin CA to the top and bottom of

each hinge. Do not use CA accelerator. After the CA has
fully hardened, test the hinges by pulling on the aileron.

❏ ❏ 9. Locate the right aileron servo’s cover. Find the

aileron's servo opening on the bottom surface of the wing
(fourth bay in from the wing tip). Cut out the covering 1/8"
[3mm] inside the opening. Use a trim iron to seal the
covering around the edges of the opening.

❏ ❏ 10.Trial fit the aileron servo cover.It should fit snugly.

Drill four 1/16" [1.6mm] holes on the corners of the aileron
servo cover through the wing's structure. Use four #2 x 3/8"
[9.5mm] screws to hold the aileron servo cover in place.
Make sure the slot for the servo arm is nearest the wing tip.

❏ ❏ 11. Take the aileron servo cover off and wick some

thin CA into the screw holes both in the wing's structure and
in the servo covers.
