assembly instructions - Global Hobby Distributors

The Fokker Dr.1 is one of the most famous and recognizable fighter planes of World War One. The Fokker Dr.1 (Dr standing for Dreidecker or 3
wings) was designed by Reinhold Platz and was ordered into production on July 14, 1917, in response to the success of the British Sopwith Triplane
earlier in the year. The first production model of the Fokker Dr.1 was delivered personally by Tony Fokker to the Red Baron, Rittmeister Manfred
von Richthofen, and shortly after that in August of 1917 it made its first appearance in combat.
Pilots were impressed with its maneuverability and soon scored victories with the nimble triplane. In the hands of an experienced pilot, the Fokker
Dr.1 was a formidable dogfighter. The three wings produce tremendous lift which, combined with its small size and weight, meant it could out climb
and out-turn almost any opponent.

●
recommended radio, receiver and servos
You will need to use a 4 or more channel transmitter with a 4 or more channel
micro receiver. You can use just a basic transmitter, although one that features
dual rates would be better. The receiver should be as light as possible,
preferably around 9 grams
The servos you use should be the lightest available, yet still have an adequate
amount of torque. We suggest using servos that weigh no more than 5 grams. For the ailerons, we suggest two 4 gram 10oz/in servos and for the elevator and rudder we suggest two 5 gram 12oz/in servos. Cirrus CS101 micro servos will work well for the ailerons and CS201 micro servos will work well for the elevator and the rudder.

TIPS FROM THE PROS
Covering Material:
The covering material used on your airplane is real iron-on, heat-shrink covering material. 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. To remove
any wrinkles that might be visible you will need to use a heat-sealing covering iron.
Follow this simple procedure to remove the wrinkles:
❑ Plug in and turn on the sealing iron to the medium-high temperature setting. Allow the sealing iron to heat up for approximately
5 - 7 minutes.
❑ After the sealing iron has reached temperature, lightly apply the sealing iron to the wrinkled section of the covering. Move the
sealing iron slowly over the wrinkled section until the covering tightens and the wrinkles disappear. If the color layer smears from any
of the seams you can remove the color streaks using a paper towel soaked with a small quantity of acetone.
Checking the Wings for Warps:
While many precautions have been taken during the production process to ensure that your airplane is constructed error-free, you
should check the wings to ensure that they have no warps. Warps can develop from the different temperature and humidity extremes
seen during the transport and shipping processes. To check for warps, look at each wing from the tip of the wing. Look carefully
down both the leading edge and the trailing edge. They should be straight. If you see a warp, you can remove it by twisting the wing
in the opposite direction of the warp, then by reshrinking the covering material tightly.
Storage and Transport:
We do not suggest storing your airplane in an extremely hot environment (like the back of your car in direct sunlight) for any length
of time. The extreme heat could cause the covering material to wrinkle and possibly damage the fragile components of the radio
control system or battery.
Page MOTOR AND COWLING INSTALLATION
You'll Need the following parts FROM THE KIT:
❑ (1) Fuselage
❑ (1) Plywood Motor Mount Plate
❑ (1) Cowling
❑ (3) M2 x 8mm Wood Screws
❑ (1) Motor Mount Stick
You'll Need the following TOOLS AND SUPPLIES:
❑ Kwik Bond 5 Minute Epoxy
❑ Pencil
❑ Kwik Bond Thin C/A
❑ Masking Tape
❑ # 0 and # 2 Phillips Head Screwdrivers
❑ Paper Towels
❑ Excel Modeling Knife
❑ Rubbing Alcohol
❑ Electric or Hand Drill
❑ NHP Epoxy Mixing Sticks
❑ 1/16" (1.6mm) and 1/8" (3.1mm) Drill Bits
❑ NHP Epoxy Mixing Cups
❑ Ruler
sTEP 1A: INSTALLING THE MOTOR - KMS BRUSHLESS OUTRUNNER OR SIMILAR
❑ Using the scribe lines on the plywood motor mount plate, position and
drill holes through the motor mount plate to install your motor.
❑ Install your motor onto the plywood motor mount plate, using the screws
provided with your motor.
IMPORTANT Use pan head screws to install your motor, so that when
tightened, they'll be flush with the surface of the motor mount plate. This
will prevent the screw heads from interfering with the installation of the
motor assembly onto the firewall.
❑ Glue the motor mount plate to the firewall, making sure that the radius
along the top of the motor mount plate matches the radius along the top of
the cutout in the firewall.
PRO TIP Depending on the length of the motor wires, you might want to
connect your ESC now, before installing the motor. If the motor wires are
too short, it can be difficult to reach them through the cockpit later.
sTEP 1B: INSTALLING THE MOTOR - Brushed stick mount motor
❑ Carefully cut out the three mounting squares and the circle that are etched
on the firewall. A sharp modeling knife works well for this.
Page ❑ Glue the motor mount stick to the firewall from the back.
❑ Slide your motor assembly firmly onto the motor mount stick. When
positioned correctly, the back of the nut that the propeller fits over should be
1-3/4" (44mm) in front of the firewall (A). This will ensure that the cowling
will line up when it's installed.
☞Depending on the motor assembly that you're using, you may need to
cut the motor mount stick shorter to achieve the correct measurement.
IMPORTANT The back of the motor is supposed to slide into the cutout near the bottom of the firewall. It might be necessary
for you to enlarge the hole slightly so that your motor will fit without rubbing against the firewall.
❑ When satisfied with the alignment, secure the motor assembly to the
motor mount stick using two short wood screws (not included).
sTEP 2: INSTALLING THE cowling
❑ Align the cowling on the fuselage and hold it in place with pieces of
masking tape. When aligned properly, the molded lip on the back of the
cowling should overlap the front of the fuselage evenly and the edges of the
cutout in the bottom of the cowling should line up equally over the bottom
sides of the fuselage. The hole in the front of the cowling should be centered
around the motor shaft, too.
❑ The cowling is held in place with three wood screws - one at each bottom
corner and one at the top. Drill 1/16" (1.6mm) pilot holes into the cowling
and through the fuselage, then install the wood screws.
PRO TIP Before installing the wood screws, apply a drop of thin C/A into
the pilot holes to strengthen the surrounding plywood.
☞Plywood plates have been preglued into the fuselage to thread the wood
screws into.
Page STABILIZER AND RUDDER INSTALLATION
You'll Need the following parts FROM THE KIT:
❑ (1) Horizontal Stabilizer with Elevator
❑ (2) Plywood Control Horns (Large)
❑ (1) Rudder
❑ (2) M3 x 25mm Machine Screws
❑ (6) C/A-Style Hinges
You'll Need the following TOOLS AND SUPPLIES:
❑ Kwik Bond Thin and Thick C/A
❑ Ruler
❑ # 2 Phillips Head Screwdriver
❑ Pencil
❑ Excel Modeling Knife
❑ T-Pins
sTEP 1: HINGING THE ELEVATOR
❑ Mark the four locations for the elevator hinges onto the elevator.
❑ Carefully cut four hinge slots in the leading edge of the elevator at the
marks that you drew.
IMPORTANT Make sure that you cut the hinge slots on the centerline
of the leading edge.
❑ Push one T-pin through the center of four hinges, then slide the hinges into
the hinge slots, making sure that you push each hinge in up to the T-Pins.
☞Don't glue the hinges into the elevator yet.
PRO TIP The T-pins will keep the hinges centered when you hinge the
elevator.
❑ Cut the corresponding hinge slots in the trailing edge of the stabilizer,
then push the elevator and its hinges into place.
IMPORTANT Again, make sure to cut the hinge slots on the centerline
of the trailing edge.
❑ Remove the T-Pins and push the elevator up against the trailing edge. There should be no more than 1/32" wide hinge gap and the tips of the
elevator should not rub against the ends of the stabilizer.
❑ While holding the elevator tight against the trailing edge, pivot the elevator
down 45º and apply 3-4 drops of thin C/A to the exposed area of each hinge. Turn the stabilizer over and repeat for the other side of the hinges.
Page sTEP 2: installing the elevator control horn
IMPORTANT The elevator pushrod exit slot is on the right side of the fuselage. When installing the control horn in the next
procedure, it's important to install the control horn so that it's toward the bottom of the elevator and will be on the RIGHT SIDE of
the fuselage when the stabilizer assembly is mounted.
❑ Cut away the covering material from over only the bottom of the control
horn mounting slot in the elevator. Please see the important note above.
❑ Glue one control horn into the mounting slot, making sure that the control
horn is facing forward.
sTEP 3: mounting the stabilizer assembly
❑ Cut away the covering material from over the stabilizer mounting holes
in the fuselage and from over the top and bottom of the mounting holes in
the stabilizer.
IMPORTANT Don't skip the next procedure. The C/A will harden the surrounding plywood, preventing the threads from stripping
when you install the machine screws.
❑ Apply a couple of drops of thin C/A into the stabilizer mounting holes in
the fuselage and let it dry completely.
❑ Mount the stabilizer to the fuselage, using the two M3 x 25mm machine
screws provided.
IMPORTANT Be careful not to overtighten the machine screws or you'll
crush the stabilizer. The screws need only be tightened snugly.
sTEP 4: hinging the rudder
❑ Cut away the covering material from over the control horn mounting slot
in only the left side of the rudder.
❑ Glue the control horn into the mounting slot, making sure that the control
horn is facing forward.
Page 10
❑ Cut two hinge slots in the leading edge of the rudder, equally spaced
between the top and bottom, then slide the hinges into place, using the same
techniques that you did to install the hinges in the elevator.
IMPORTANT As with the elevator, make sure to cut the hinge slots on
the centerline of the leading edge.
❑ Cut the corresponding hinge slots in the back of the fuselage, then hinge
the rudder to the fuselage, using the same techniques that you used to hinge
the elevator to the stabilizer.
❑ After allowing the C/A to completely cure, gently pull on the elevator and rudder to check the integrity of the hinges. The hinges
should hold securely. If one or more hinges is loose, apply more C/A to the hinge(s).

back of the fuselage.
+Depending on the size of your servos, you may need to enlarge the
servo mounting holes.
sTEP 2: INSTALLING THE ELEVATOR linkage assembly
❑ Cut away all but one arm from a servo horn, then attach one pushrod into
the outermost hole in the servo arm.
Page 11
❑ Cut away the covering material from over the elevator pushrod exit slot
in the right side of the fuselage.
❑ Center the elevator servo (the right-side servo).
q Slide the plain end of the pushrod through the fuselage and out the
elevator pushrod exit slot, then attach the servo horn to the servo, making
sure that it's centered and pointing toward the fuselage side.
☞Don't forget to install the servo horn retaining screw.
❑ With both the elevator and the elevator servo centered, cut off the pushrod
right at the front of the control horn.
❑ Slide a piece of heat-shrink tubing over the pushrod, then attach one
prebent wire to the outermost hole in the control horn.
❑ Center both the elevator servo and the elevator, then slide the heat-shrink
tubing over the wire.
❑ Double-check that both the elevator servo and the elevator are centered,
then use a heat gun to shrink the heat-shrink tubing.
sTEP 3: INSTALLING THE rudder linkage assembly

sTEP 2: INSTALLING THE landing gear struts
❑ Cut away the covering material from over the landing gear strut mounting
slots in the top of the gear wing.
IMPORTANT The landing gear struts are not the same. One is narrower and one is wider. The narrower strut should be toward
the back of the gear wing (A) and the wider strut should be toward the front of the gear wing (B).
❑ Install the landing gear struts into the predrilled holes in the mounting
slots.
❑ Secure the landing gear struts to the gear wing using the two straight
aluminum brackets and four M2 x 8mm wood screws. Center the brackets
over the landing gear struts, then mark and drill 1/16" (1.6mm) pilot holes
for the wood screws.
PRO TIP Apply a drop of thin C/A into each pilot hole to strengthen the
surrounding plywood.
sTEP 3: INSTALLING THE gear wing assembly
IMPORTANT Pilot holes have been predrilled into the fuselage at the landing gear strut bracket mounting locations. You should
be able to see the pilot holes underneath the covering material if you look carefully. After you remove the covering material from

IMPORTANT Be careful not to overtighten the machine screws. The
screws need only be tightened snugly.
Page 15
sTEP 2: INSTALLING THE center wing
❑ Cut away the covering material from over the top and bottom of the
wing-screw mounting holes in the center wing, then cut away the covering
material from over the outer wing strut mounting slots in both the top and
the bottom of the wing.
❑ Apply a couple of drops of thin C/A into the center wing mounting holes
in the fuselage and let it dry completely.
IMPORTANT There are a total of four outer wing struts included. For this step, make sure that you are using the two that are
labeled "DOWN". These are for the bottom wing. "DOWN" is lasered on the lower mounting tab.
Before installing the two outer wing struts in the next procedure, make sure that you install them so that they are angled forward
and that mounting tab with the "DOWN" label is glued into the bottom wing.
❑ Fit and glue the two outer wing struts into the mounting slots in the top
of the bottom wing.
IMPORTANT Again, make sure that you install the outer wing struts so
that they are angled forward and that the mounting tab with the "DOWN"
label is glued into the wing.
IMPORTANT In the next two procedures, you'll install the center wing. DO NOT glue the outer wing struts to the center wing. If you do, it will be impossible to remove either the bottom wing or the center wing from the fuselage. The outer wing struts fit into
the center wing without using glue.
❑ Mount the center wing to the fuselage, using the remaining two M3 x 25mm
machine screws.
IMPORTANT Be careful not to overtighten the machine screws. The
screws need only be tightened snugly.
❑ Gently flex the ends of the bottom wing down, then push the mounting
tab in the outer wing struts into the wing strut mounting slots in the bottom
of the center wing.
☞Again, do not glue the outer wing struts to the center wing.

sTEP 3: INSTALLING THE center wing fairing
❑ Cut away the covering material from over the two predrilled center wing
fairing mounting screw pilot holes in the leading edge of the wing.
❑ Apply a couple of drops of thin C/A into the pilot holes and let it dry
completely.
❑ Secure the front of the center wing fairing to the wing, using two M2 x 8mm
wood screws.
❑ If necessary, trim the sides of the cutout in the back of the center wing
fairing to fit around the front of the cockpit.
❑ Press the center wing fairing flat against the surface of the wing, then
use pieces of masking tape to hold it in place.
❑ Install two M2 x 8mm wood screws to secure the back of the center wing
fairing to the wing.

angle cut (A) on each cabane strut should be toward the trailing edge of the wing.
A
❑ Install the right and left cabane struts to the bottom of the wing, using
four M2 x 8mm wood screws. Pilot holes have been predrilled to mount the
cabane struts, just to the outside of the servo lead exit holes.
IMPORTANT Before installing the wood screws, apply a drop of thin
C/A to harden the surrounding plywood.
Page 19
IMPORTANT Before installing the two outer wing struts in the
next procedure, make sure that you install them so that they are angled
backward toward the trailing edge and that mounting tab with the
"ASCENDING" label is glued into the top wing.
❑ Cut away the covering material from over the outer wing strut mounting
slots in the bottom of the wing, then fit and glue the two outer wing struts
into the mounting slots.
sTEP 3: installing the top wing
❑ Set the wing onto the fuselage and push the mounting tab in the outer
wing struts into the wing strut mounting slots in the center wing.
IMPORTANT As with the two lower outer wing struts, don't glue the
upper outer wing struts to the center wing or it will be impossible to
remove the wing if you need to. The outer wing struts fit into the center
wing without using glue.
❑ Secure the cabane struts to the front mounting brackets, using two
M2 x 6mm machine screws and two M2 hex nuts.
IMPORTANT Mount the cabane struts to the outside of the mounting
brackets.
❑ Secure the cabane struts to the rear mounting brackets, using two
M2 x 6mm machine screws and two M2 hex nuts.
IMPORTANT Mount the cabane struts to the outside of the mounting
brackets.
❑ Double-check the alignment of the wings. When viewed from the front, all three wings should be level with each other. Check
the stabilizer, too. It should be level with the wings. If it's not, loosen the mounting screws and install a thin shim under the low side
and retighten the screws. Next, check the wings from the top. They should all be parallel with each other and straight.

Page 20
sTEP 1: installing the wing tip skids
❑ Cut away the covering material from over the wing tip skid mounting slots
in the bottom of the bottom wing, then fit and glue the two wing tip skids into
place.
sTEP 2: installing the electronic speed control
❑ Mount your ESC to the fuselage side, directly behind the firewall, using
a piece of double-sided foam tape (not included).
PRO TIP Depending on the length of your ESCs battery wires, you may
want to solder longer wires into place to make it easier to plug in and
unplug your battery.
❑ If your ESC features an on/off switch, mount it in a convenient place on
the side of the fuselage.
sTEP 3: installing the receiver
❑ Join the two aileron servo leads using a Y-harness and push the excess wires up into the wing through the servo lead exit holes. Use a couple of pieces of clear tape (not included) to secure the aileron servo lead to the cabane strut where it enters the cockpit.
❑ Plug the servo and ESC leads into their proper slots in your receiver, then
mount your receiver to bottom of the cockpit floor, underneath the servos,
using a piece of double-sided foam tape (not included).
❑ Run the antenna out the bottom of the cockpit and secure it along the
bottom of the fuselage, using pieces of clear tape (not included). Do not
cut the antenna shorter. Allow the excess to hang beyond the back of
the fuselage.
sTEP 4: installing the battery
❑ To make it easier to install and remove the battery, make a handle out of
a length of strapping tape (or other type of strong tape) and firmly adhere it
to your battery.
❑ Mount the battery to the fuselage floor, directly behind the firewall, using
a piece of hook and loop material (not included).

BALANCE POINT AND CONTROL THROWS
Balance Point:
The Center of Gravity (C/G or Balance Point) is 1" (25mm) back from the leading edge of the CENTER wing, measured at
the middle of the wing.
WARNING Do not balance the airplane further back than recommended or the airplane will be very difficult to control, especially
in pitch. An uncontrollable crash could result!
CONTROL THROWS:
Ailerons:
1/2" (13mm) Up & Down
Elevator:
5/8" (15mm) Up & Down
Rudder:
3/4" (19mm) Right & Left
These control throws are a good starting point. Once you become more familiar with the flight characteristics of the airplane,
you can increase the control throws a little bit at a time until you're satisfied with the result.
The control throws are measured from the widest point of the control surfaces
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.
WARNING Do not turn the receiver on unless the transmitter is turned on first. Always turn the transmitter on first. Never allow
hands or clothing to get in the way of the propeller when the radio is turned on. Sudden unwanted radio signals, or turning the radio
on with the throttle stick set at full throttle, can turn the motor on unintentionally. Always make sure that the throttle control stick is
set to idle before turning on the transmitter.
B) When the throttle control stick is at the idle position, the motor should be off. Moving the stick forward should turn on the
motor. Gradually moving the stick to the full forward position should result in the motor running at full power.
☞If you're using a computer radio, you may need to increase your throttle channel's EPA setting to result in full power. (Refer to
your radio system's operating guide for further information.)
Check the condition of the transmitter batteries. They should be fully charged.
●
Check every glue joint in the airplane to ensure that everything is tight and well-bonded.
●
Double-check that you've installed and tightened all of the servo horn retaining screws.
●
Double-check that the battery is properly secured into place. There's nothing worse than the battery coming loose during flight.
●
Double-check the balance of the airplane. Do this with the battery installed and the airplane ready to fly.
●
Check the control surfaces. They should all move in the correct direction and not bind.
●
If your radio transmitter is equipped with dual rate switches, double-check that they are on the low-rate setting for your first few
flights.
●
Check to ensure that all of the control surfaces are moving the proper amount in both low and high rate settings.
●
● Check the receiver antenna. It should be fully extended and not coiled up. Do not cut the receiver antenna shorter or the range of
your radio control system will be greatly reduced.
You should complete a successful range check of your radio equipment prior to each new day of flying, or prior to the first flight of
a new or repaired model.
●
● You should not knowingly operate your R/C radio system within 3 miles of a preexisting model club flying field without a frequency
sharing agreement with that club.
