INTRODUCTION
High in the skies over war-torn Europe during WW1 lurked a
man and machine combination that struck terror in the hearts
and minds of the allied forces.The man–Baron Manfred Von
Richtofen; the machine–the Fokker DR-1. Together they
forged the legend of the bloody “Red Baron”!
The Fokker DR-1 is to this day, nearly a century after the
record-setting exploits of the “Red Baron,” one of the most
highly recognized airplanes in the world. Now you can have
this great looking and flying model as an electric, without the
mess and fuss of a glow-powered engine.
With today’s LiPo (Lithium-Polymer) batteries and micro
servos, small electrics have become very popular. Now
Great Planes brings you the Fokker DR-1 in a small, easy to
fly, ARF electric. So if you want to impress your glow-flying
buddies with an electric, the Great Planes Fokker DR-1 EP
ARF is just what you need.
For the latest technical updates to the Fokker DR-1 EP ARF,
visit the Great Planes web site at www.greatplanes.com.
Open the “Airplanes” link and select the Fokker DR-1 EP
ARF.IF there is new technical information or changes to this
model, a “tech notice” box will appear in the upper left corner
of the page.

IMPORTANT!! Two of the most important things you can do
to preserve the radio controlled aircraft hobby are to avoid
flying near full-scale aircraft and avoid flying near or over
groups of people.

PROTECTYOUR MODEL,YOURSELF
& OTHERS....FOLLOWTHESE
IMPORTANT SAFETY PRECAUTIONS
1.Your Fokker DR-1 EP ARF should not be considered a toy,
but rather a sophisticated, working model that functions very
much like a full-size airplane. Because of its performance
capabilities, the Fokker DR-1 EP ARF, if not assembled and
operated correctly, could possibly cause injury to yourself or
spectators and damage to property.
2.Youmustassemblethemodelaccordingtotheinstructions.
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.Take your time to build straight, true and strong.
4. You must use an R/C radio system that is in
first-class condition.
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 an experienced pilot or have not flown
this type of model before, we recommend that you get the
assistance of an experienced pilot in your local 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.
We, as the kit manufacturer, provide you with a top quality,
thoroughly tested kit and instructions, but ultimately the
quality and flyability of your finished model depends
on how you build it: therefore, we cannot in any way
guarantee the performance of your completed model,
and no representations are expressed or implied as to the
performance or safety of your completed model.
Remember:Take your time and follow the instructions to
end up with a well-built model that is straight and true.

PREPARATIONS
❏1. If you have not done so already, carefully remove the
major parts of the kit from the box (wing, fuselage (fuse),
tail parts, etc.) and inspect them for damage. If any parts
are damaged or missing, contact Product Support at the
address or telephone number listed on page 5.
❏2. Carefully separate the ailerons from the wing, the
rudder from the fin and the elevator from the stabilizer (stab).
If necessary, use a covering iron set on medium/high to
carefully tighten the covering. Lay the control surface on
a flat surface and apply pressure over sheeted areas to
thoroughly bond the covering to the wood.Hint: Poke three
or four pin holes in the covering over the open structure in
the tail surfaces. This will allow the hot air to escape while
tightening the covering.
WARNING: DO NOT OVER-SHRINK THE COVERING OR
ITWILL CAUSE THE CONTROL SURFACESTOTWIST.
❏3. Check the pre-cut hinge slots of all control surfaces
using a hobby knife with a #11 blade. This will help when
installing the hinges.
ASSEMBLETHE WING
Install the Ailerons
❏1.Test fit the right aileron to the top wing with three 5mm
x 10mm [13/64" x 3/8"] hinges. If the hinges don’t stay
centered, stick a pin through the middle of the hinges to hold
them in position while fitting the aileron to the wing.
❏2. Remove any pins you may have inserted into the hinges.
Install theaileron so thereis a very smallgap betweenthe LE of
the aileronand the wing.The gap shouldbe small –just enough
to see light through or to slip a piece of paper through.
❏3. Apply three drops of thin CA to the top and bottom of
each hinge. Do not use CA accelerator. After the CA has
cured, test the hinges by pulling on the ailerons.
❏4. Repeat steps 1 to 3 for the left aileron.
6

ASSEMBLETHE FUSE
Mount the BottomWing
❏1.Locate two of the 3mm x 24mm [1/8" x 15/16"] dowel rods
and insert them into the bottom wing as shown, so that only
about 9mm [11/32"] sticks out.Secure them with medium CA.
❏2. Test fit the bottom wing to the fuse and secure it with
two 3mm x 24mm [1/8" x 15/16"] machine screws and 3mm
[1/8"] washers.The flat side of the wing is the bottom.
Mount the Stab & Fin
❏1. Using a sharp hobby knife, remove the covering from
the stab cut-out at the aft end of the fuse.
❏2. Mark the center of the TE of the stab. Place the stab
onto the stab saddle.
❏3.Stick aT-pin into the center of the top of the firewall.Tie
a small loop in one end of a 900mm [35"] piece of non-elastic
string such as K&S #801 Kevlar thread. Slip the loop in the
string over the T-pin.
❏4. Fold a piece of masking tape over the other end of the
string and draw an arrow on it.With the stab centered on the
fuse and the TE of the stab flush with the aft end of the fuse,
slidethetapealong the stringandalignthearrowwith one tip of
the stab.Swing the string over to the same position at the other
end of the stab.If the arrow doesn’t align with the tip, adjust the
stab and the arrow slightly and check both tips again. Adjust
the stab until the stab tips and the TE are centered.
❏5. View the stab from approximately 3m [10'] behind the
plane. Check that the stab is parallel with the wing. If it is
not, lightly sand the stab saddle until the stab is parallel with
the wing.
7

❏6. Use a fine-point felt-tip pen to mark the outline of the
fuse onto the bottom of the stab.
❏7.Remove the stab from the fuse.Use a sharp #11 hobby
knife or the “ExpertTip” that follows to cut the covering from
the stab just inside the lines you marked. Use care to cut
only the covering and not the wood. Cutting the wood will
weaken the stab and it may break in flight.
HOWTO CUT COVERING FROM BALSA
Use a 25-watt soldering iron to cut the covering from the
stab.The tip of the soldering iron doesn’t have to be sharp,
but a fine-tip does work best. Allow the iron to heat fully.
Use a metal straightedge to guide the soldering iron at a
rate that will just melt the covering and not burn into the
wood.The hotter the soldering iron, the faster it must travel
to melt a fine cut. Allow the heat to melt the covering. Do
not apply much pressure or the wood may be damaged.
Peel off the covering.
❏8.Reinstall the stab onto the fuse.Use the string method to
align the stab and glue it in place with thin CA.
❏9.Temporarily attach the elevator to the stab with four CA
hinges. IMPORTANT: There is a left and right side to the
elevator. The bottom, right side of the elevator has a small
slot for the elevator control horn. Be sure the elevator half
with the slot is on the bottom, right side of the fuse. Use
T-pins to hold the CA hinges centered in the elevator as you
did when installing the ailerons on the Top wing. Apply 3
drops of thin CA on the top and bottom of each hinge.
❏10. Install the 10mm x 21mm [3/8" x 13/16"] CA hinge
in the rudder and test fit it into the rear of the fuse. Adjust
the rudder so that the bottom is even with the bottom of the
fuse. Use a small modeling square to make sure that it is
perpendicular to the stab. Apply 3 drops of thin CA on each
side of the hinge.
❏11. Test fit the tail skid at the rear of the fuse. When
satisfied with the fit, attach the tail skid to the bottom of the
fuse using medium CA.
RADIO INSTALLATION
Install the Motor & ESC
Note: You will need to have your motor battery charged later in
this section. We recommend that you start charging it now so
youdo nothave towaitforit to chargelater.Make sureto closely
follow the charging instructions for charging LiPo batteries.We
also recommend that you remove the bottom wing for this
procedure for better access to the inside of the fuse.
❏1. Use epoxy to join the two piece motor mount. Make
sure all openings align.
8

❏2. Attach the RimFire motor to the back of the plywood
motor mount with three 3mm x 6mm [1/8" x 15/64"] machine
screws. Apply a drop of threadlocker on the threads of the
machine screws. Insert each of three 3mm x 30mm [1/8" x
1-3/16"] machine screws through a 3mm [1/8"] washer, the
outer holes of the motor mount, another 3mm [1/8"] washer, a
17mm[21/32"]tube,andanother 3mm [1/8"] washerasshown
in the drawing.Apply a drop of threadlocker on the threads of
each screw and install the motor mount to the firewall.
❏3.Cut a 20mm [3/4"] long piece of hook and loop material
(not included). Glue the 20mm [3/4"] soft piece (loop side)
to the back of the ESC. Glue the rough piece (hook side) to
the side of the fuse, next to the battery tray. Insert the ESC
into the battery door and through the cut-out just to the rear
of the firewall and secure it in place by joining the hook and
loop material. Route the servo lead into the wing opening
area and the three motor leads out the front of the firewall.
❏4. Install a 3.5mm [9/64"] Bullet (male) to 2mm [5/64"]
Bullet (female) connector adapter (GPMM3122) on each of
the motor leads. Connect the motor leads to the ESC. Push
the wires up into the fuse to prevent them from contacting the
rotating motor case.Check the motor for proper rotation.
❏5. Cut another 20mm [3/4"] long piece of hook and loop
material (not included) and glue the 20mm [3/4"] soft piece
(loop side) to the back of the receiver. Glue the rough piece
(hook side) to the top of the inside of the fuse on the ledge by
the cockpit opening.Insert the receiver and secure it in place
by joining the hook and loop material.
Install the Linkages
❏1. Insert a control horn into the rudder slot and elevator
slot as shown. Use a hobby knife to enlarge the hole if
necessary. Once satisfied with the fit, use CA to secure the
control horns in place.
❏2. Insert the two 460mm [18"] wire pushrods into the
pushrod exits at the rear of the fuse as shown below.
❏3. Insert the 90° bends of the 460mm [18"] pushrods into
the outer hole of the control horns and secure them with
the plastic retainers as shown. Place a drop of CA on the
outer surface of the plastic retainers.
Install the Servos
❏1. Install the servo mounting hardware and servo arms
on the rudder and elevator servos.Trim off the unused servo
9

arms. Insert a screw-lock pushrod connector in the hole of
each servo arm approximately 9mm [11/32"] from the center
of the servo.Secure the screw-lock pushrod connector to the
servo arm with a nylon retainer.
❏2.Position the servoson the servorails,aligning them with
the pushrod wires. Drill a 1.6mm [1/16"] hole through each
of the mounting holes in the servo. Install and then remove
a servo mounting screw into each of the holes you drilled.
Apply thin CA into each hole to harden the threads.After the
gluehashardened,plug the ESC,rudderand elevatorservos
into the receiver. Switch on the transmitter and then plug a
battery pack into the ESC.Center the trims on the transmitter
and re-center the servo arms on the servos if necessary so
that the arm is perpendicular to the centerline of the servo.
Insert the rudder and elevator pushrod wires into the screw-
lock pushrod connectors and install the rudder and elevator
servos on the servo rails.Use the hardware included with the
servos to mount the servos to the rails.
❏3. Center the elevator control surface and tighten the
set screw in the screw-lock pushrod connector against the
elevator pushrod.
❏4.Follow the same procedure to secure the rudder pushrod.
❏5. Clean the cases of both aileron servos with denatured
alcohol. Use CA to glue the aileron servos on the bottom of
the aileron servo hatches so that the servo arm is centered
in the opening. Cut off all of the unused servo arms as you
did in Step 1.If you prefer, wrap electrical tape or heat-shrink
tubing around the servos before gluing them to the servo
hatch.This will allow the servos to be removed easily.
❏6. Inside the aileron servo bays of the top wing, there is
a string that runs from one bay to the other. Plug the left
aileron servo into a 610mm [24"]Y-harness and tie the string
around the right aileron servo plug.Be sure to secure the left
aileron servo connection with heat-shrink tubing.
TIP: After tying the string to the right aileron servo plug,
use tape to keep the string and plug headed in the same
direction. This accomplishes two things; it keeps the plug
from doubling back over itself and keeps the string securely
fastened to the plug.
❏7.Carefully pull the other end of the string until theY-harness
is near the small opening near the center of the top wing.
Note: Standard size servo connectors have to be worked
through the wing slowly and carefully so as not to damage
the structure of the wing. Be patient. This can be a rather
long step.
❏8.Carefully use a bent paper clip or some type of grasping
device to carefully pull out the connector for the receiver.
Leave the right aileron servo connector tied to the string.
❏9. Continue pulling the string until the right aileron connector
enters the right aileron bay. Disconnect the string and plug in the
right aileron servo.Secure the connection with heat-shrink tubing.
10

❏10. Secure each aileron servo hatch to the wing with four
2mm x 6mm [5/64" x 15/64"] self-tapping washer head screws.
❏11. Test fit the control horns into the small rectangular
holes along the LE of the bottom of each aileron as shown.
When satisfied with their fit, CA them in place as shown.
❏12. Install one 35mm [1-3/8"] aileron pushrod in the outer
hole of the aileron servo arm and another in the outer hole of
the aileron control horn. Slide one of the included pieces of
heat-shrink tubing over the pushrods.With the radio system
on and the aileron servo trim lever centered, shrink the heat-
shrink tubing over the pushrods and apply a couple of drops
of thin CA to the tubing. Note: A hot soldering iron works
great for shrinking the heat-shrink tubing. Place the top wing
aside for the time being.
❏13. Make a small hole in the bottom sheeting. Route the
antenna out of the hole and tape it to the bottom of the fuse
with clear tape.
❏14. Run the Y-harness receiver plug from the top wing
through the slot on the top of the fuse and plug it into the
appropriate receiver channel.Re-install the bottom wing.

❏1. Locate the two remaining 3mm x 24mm [1/8" x 15/16"]
dowel rods and insert them into the middle wing as shown,
so that only about 9mm [11/32"] sticks out.Secure them with
medium CA.
❏2. Place the middle wing on the wing saddle as shown
and secure it with two 3mm x 24mm [1/8" x 15/16"] machine
screws and 3mm [1/8"] washers.The flat side of the wing is

15

Warning! Once the battery is connected to the ESC, stay
clear of the propeller even if the ESC has not been armed.
Set the ControlThrows
Use a Great Planes AccuThrow (or a ruler) to accurately
measure and set the control throw of each control surface
as indicated in the chart that follows. If your radio does not
have dual rates, we recommend setting the throws at the
low rate setting.
Note: The throws are measured at the widest part of the
elevators, rudder and ailerons.
These are the recommended control surface throws:
High Rate Low Rate
ELEVATOR: 3/8" [10mm] up 1/4" [6.4mm] up
3/8" [10mm] down 1/4" [6.4mm] down
RUDDER: 1" [25mm] right 5/8" [16mm] right
1" [25mm] left 5/8" [16mm] left
AILERONS: 3/8" [10mm] up 1/4" [6.4mm] up
3/8" [10mm] down 1/4" [6.4mm] down
IMPORTANT: The Fokker DR-1 EP ARF has been
extensively flown and tested to arrive at the throws at
which it flies best. Flying your model at these throws will
provide you with the greatest chance for successful first
flights. If, after you have become accustomed to the way
the Fokker DR-1 EP ARF flies, you would like to change
thethrowstosuit yourtaste,that is fine.However, toomuch
control throw could make the model difficult to control, so
remember, “more is not always better.”
Balance the Model (C.G.)
More than any other factor, the C.G. (balance point) can
have the greatest effect on how a model flies, and may
determine whether or not your first flight will be successful.
If you value this model and wish to enjoy it for many flights,
DO NOT OVERLOOK THIS IMPORTANT PROCEDURE.
A model that is not properly balanced will be unstable and
possibly unflyable.
At this stage the model should be in ready-to-fly condition
with all of the systems in place including the motor, landing
gear, motor battery, and the radio system.
❏1.Use a felt-tip pen or 3mm-wide [1/8"] tape to accurately
mark the C.G. on the bottom of the top wing on both sides
of the fuse.The C.G. is located 51mm [2"] back from the LE
of the top wing.
Thisis where yourmodel shouldbalance forthefirst flights.
Later, youmaywish to experimentbyshiftingtheC.G.upto
3mm [1/8"] forward or 3mm [1/8"] back to change the flying
characteristics. Moving the C.G. forward may improve the
smoothness and stability, but the model may then require
more speed for takeoff and make it more difficult to slow
for landing. Moving the C.G. aft makes the model more
maneuverable, but could also cause it to become too
difficult to control. In any case, start at the recommended
balance point and do not at any time balance the model
outside the specified range.
❏2. If you are balancing the Fokker DR-1 EP ARF on the
Great Planes CG Machine, you will find that the angle of
the supports does not allow you to rest the plane forward
enough to reach the balance point. To remedy this, simply
place the front of the CG Machine on a raised surface
(approx. 2" [51mm]). This will allow the plane to be placed
further forward on the balancer.
❏3. If the tail drops, the model is “tail heavy” and the motor
batteryand/orreceivermustbeshiftedforwardorweightmust
be added to the nose to balance.If the nose drops, the model
is “nose heavy” and the motor battery and/or receiver must
be shifted aft or weight must be added to the tail to balance.
If possible, move the receiver forward or aft to minimize or
eliminate any additional ballast required. If additional weight
is required, use Great Planes“stick-on”lead (GPMQ4485).A
good place to add stick-on nose weight is under the battery
cover (don’t attach weight to the cowl–it is not intended to
support weight). Begin by placing incrementally increasing
amounts of weight on the bottom of the fuse over the firewall
until the model balances. Once you have determined the
amount of weight required, it can be permanently attached.
If required, tail weight may be added by cutting open the
bottom of the fuse and gluing it permanently inside.
IMPORTANT: If you found it necessary to add any weight,
recheck the C.G. after the weight has been installed.
16

Balance the Model Laterally
❏1. With the wing level, lift the model by the prop shaft
and the bottom of the fuse under the TE of the fuse. Do this
several times.
❏2. If one wing always drops when you lift the model, it
means that side is heavy. Balance the airplane by adding
weighttotheotherwingtip.Anairplanethathasbeenlaterally
balanced will track better in loops and other maneuvers.
PREFLIGHT
IdentifyYour Model
No matter if you fly at an AMA sanctioned R/C club site or
if you fly somewhere on your own, you should always have
your name, address, telephone number and AMA number
on or inside your model. It is required at all AMA R/C club
flying sites and AMA sanctioned flying events. Fill out the
identification tag on the back cover page of this manual and
place it on or inside your model.
Charge theTransmitter Batteries
Follow the battery charging instructions that came with your
radiocontrolsystemtochargethetransmitter.Youshouldalways
charge your transmitter the night before you go flying, and at
other times as recommended by the radio manufacturer.
CAUTION: Unless the instructions that came with your
radio system state differently, the initial charge on new
transmitter batteries should be done for 15 hours using
the slow-charger that came with the radio system.
This will “condition” the batteries so that the next charge
may be done using the fast-charger of your choice. If the
initial charge is done with a fast-charger, the batteries may
not reach their full capacity and you may be flying with
batteries that are only partially charged.
Balance the Propellers
Carefully balance your propeller and spare propellers before
youfly.An unbalanced prop can bethe singlemost significant
cause of vibration that can damage your model. Not only
will motor mounting screws and bolts loosen, possibly with
disastrous effect, but vibration may also damage your radio
receiver and servos.
We use a Top Flite Precision Magnetic Prop Balancer™
(TOPQ5700) in the workshop and keep a Great Planes
Fingertip Prop Balancer (GPMQ5000) in our flight box.
Proper Care ofYour Motor
Using multiple battery packs to run the motor for successive
flights may cause the motor to become excessively hot.We
recommend at least a 10-minute motor cool-down period
between flights.
Ground Check
Before the first flight, inspect the model closely to make sure
all screws remained tight, the hinges are secure, the prop is
secure and all pushrods and connectors are secure.
Range Check
Ground check the operational range of your radio before the
first flight of the day.With the transmitter antenna collapsed
and the receiver and transmitter on, you should be able to
walk at least 30m [100'] away from the model and still have
control. Have an assistant stand by your model and, while
you work the controls, tell you what the control surfaces are
doing. Repeat this test with the motor running at various
speeds with an assistant holding the model, using hand
signals to show you what is happening.If the control surfaces
do not respond correctly, do not fly! Find and correct the
problem first. Look for loose servo connections or broken
wires, corroded wires on old servo connectors, poor solder
joints in your battery pack or a defective cell, or a damaged
receiver crystal from a previous crash.
MOTOR & BATTERY SAFETY PRECAUTIONS
Failure to follow these safety precautions may result
in severe injury to yourself and others.
Use safety glasses when running the motor.
Do not run the motor in an area of loose gravel or sand; the
propeller may throw such material in your face or eyes.
Keep your face and body as well as all spectators away from
the plane of rotation of the propeller as you run the motor.
Keep these items away from the prop: loose clothing, shirt
sleeves, ties, scarfs, long hair or loose objects such as
pencils or screwdrivers that may fall out of shirt or jacket
pockets into the prop.
Always remove the LiPo (Lithium-Polymer) battery from the
plane before charging.
Always use a charger designed to charge LiPo batteries for
charging the LiPo flight battery.
17

Never leave the LiPo battery unattended while charging.If the
battery becomes more than just warm, discontinue charging.

FLYING
The Fokker DR-1 EP ARF is a great-flying model that flies
smoothly and predictably. The Fokker DR-1 EP ARF does
not, however, possess the self-recovery characteristics of a
primary R/C trainer and should be flown only by experienced
R/C pilots.
CAUTION (THIS APPLIES TO ALL R/C AIRPLANES): If,
while flying, you notice an alarming or unusual sound such
as a low pitched “buzz,” this may indicate control surface
flutter. Flutter occurs when a control surface (such as an
aileron or elevator) or a flying surface (such as a wing or
stab)rapidlyvibratesupanddown(thuscausingthenoise).
In extreme cases, if not detected immediately, flutter can
actually cause the control surface to detach or the flying
surface to fail, thus causing loss of control followed by
an impending crash. The best thing to do when flutter is
detected is to slow the model immediately by reducing
power, then land as soon as safely possible.Identify which
surface fluttered (so the problem may be resolved) by
checkingalltheservogrommetsfordeteriorationorsignsof
vibration.Makecertainall pushrodlinkagesaresecureand
free of play.If it fluttered once, under similar circumstances
it will probably flutter again unless the problem is fixed.
Some things which can cause flutter are; Excessive hinge
gap; Not mounting control horns solidly; Poor fit of clevis
pin in horn; Side-play of wire pushrods caused by large
bends; Excessive free play in servo gears; Insecure servo
mounting; and one of the most prevalent causes of flutter;
Flying an over-powered model at excessive speeds.
Takeoff
The Fokker DR-1 EP ARF has a tail skid rather than a
conventional tailwheel. This prevents you from having
complete control while trying to taxi. If your field has short
grassor is paved,it is recommendedthat yousetthe airplane
on the runway pointed into the wind to ready the plane for
takeoff. If your field has very thick or tall grass you should
consider hand-launching the airplane.
With the plane pointed into the wind, arm the motor as per
the ESC instructions and slowly advance the throttle. Apply
full power and launch the model into the wind with the wings
level with the horizon. Gradually add “up elevator” when the
plane picks up speed to begin a gentle climb.At this moment
it is likely that you will need to apply more right rudder to
counteract motor torque. Be smooth on the elevator stick,
allowing the model to establish a gentle climb to a safe
altitude before turning into the traffic pattern.
Flight
For reassurance and to keep an eye on other traffic, it is a
good idea to have an assistant on the flight line with you.Tell
him to remind you to throttle back once the plane gets to a
comfortable altitude.Take it easy with the Fokker DR-1 EP
ARF for the first few flights, gradually getting acquainted with
it as you gain confidence.
Adjust the trims to maintain straight and level flight. After
flying around for a while, and while still at a safe altitude
with plenty of battery power remaining, practice slow flight
and execute practice landing approaches by reducing the
throttle to see how the model handles at slower speeds.Add
power to see how she climbs as well.Continue to fly around,
executing various maneuvers and making mental notes (or
having your assistant write them down) of what trim or C.G.
changes may be required to fine tune the model so it flies the
way you like. The Fokker DR-1 EP ARF will perform loops,
hammerheads, inverted flight and rolls.
When performing rolls you will find that the rolls are more
of a barrel roll. It is recommended you are at a safe altitude
before attempting the roll until you have become familiar with
the characteristics of the airplane. Mind your battery power
but use this first flight to become familiar with your model
before landing.
Landing
WWI planes like the Fokker DR-1 are notorious for their
poor ground handling. Your model has been designed for
maximum control without excessively deviating from scale
lines.This said, the airplane is a little trickier on the ground
than other models you may have flown. We have specified
a high and low rate for the elevator. For normal flying you
will find the low rate elevator is more than adequate. You
might want to switch to the high rate for landing.The airplane
has a tendency to nose over. The additional throw provided
by the high rate elevator will help to minimize nose-overs
when landing. The Fokker DR-1 EP ARF has lots of drag
and slows down quickly when power is reduced.Practice the
landing procedure with more altitude first, then try landing!
To initiate a landing approach, lower the throttle while on
the downwind leg. Allow the nose of the model to pitch
downward to gradually bleed off altitude. Continue to lose
altitude, but maintain airspeed by keeping the nose down
as you turn onto the crosswind leg. Make your final turn
toward the runway (into the wind) keeping the nose down to
maintain airspeed and control. Level the attitude when the
model reaches the runway threshold. At this point it is best
to keep up the air speed and the RPM of the motor, flying the
plane to the ground.The plane will land best if you fly it to the
ground landing first on the main wheels and allowing the tail
to naturally settle as the speed decreases. Three point stall
landings will also work but are trickier to do on a consistent
19

basis. If you are going to overshoot, smoothly advance the
throttle (always ready on the right rudder to counteract
torque) and climb out to make another attempt. But, if your
battery power is low, do not attempt to go around again. It is
better to land long than risk stalling the plane by flying too
slow because the motor battery is low on power.
One final note about flying your model: Have a goal or flight
plan in mind for every flight. This can be learning a new
maneuver(s), improving a maneuver(s) you already know,
or learning how the model behaves in certain conditions
(such as on high or low rates). This is not necessarily to
improve your skills (though it is never a bad idea!), but more
importantly so you do not surprise yourself by impulsively
attempting a maneuver and suddenly finding that you’ve run
out of time, altitude or airspeed. Every maneuver should be
deliberate, not impulsive.For example, if you’re going to do a
loop,checkyouraltitude,mindthewinddirection(anticipating
rudder corrections that will be required to maintain heading),
remember to throttle back at the top, and make certain you
are on the desired rates (high/low rates).A flight plan greatly
reduces the chances of crashing your model just because of
poor planning and impulsive moves. Remember to think.
Have a ball! But always stay in control and fly in a
safe manner.
GOOD LUCK AND GREAT FLYING!
