INTRODUCTION
The Factor 3D EP ARF was designed from the ground up to
provide one of the best flying 3D airplanes available today.
Whether you are just learning to fly 3D or are already an
expert, you will love this airplane.
For the latest technical updates or manual corrections to the
Factor 3D EP ARF visit the Great Planes web site at www.

Academy of Model Aeronautics
We urge you to join the AMA (Academy of Model Aeronautics)
and a local R/C club.The AMA is the governing body of model
aviation and membership is required to fly at AMA clubs.
Though joining the AMA provides many benefits, one of the
primary reasons to join is liability protection. Coverage is not
limited to flying at contests or on the club field. It even applies
to flying at public demonstrations and air shows. Failure to
comply with the Safety Code (excerpts printed in the back of
the manual) may endanger insurance coverage. Additionally,
training programs and instructors are available at AMA club
sites to help you get started the right way. There are over 2,500
AMA chartered clubs across the country. Contact the AMA at
the address or toll-free phone number below:

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.
SAFETY PRECAUTIONS
PROTECT YOUR MODEL, YOURSELF & OTHERS...
FOLLOW THESE IMPORTANT SAFETY PRECAUTIONS
1. Your Factor 3D EP ARF should not be considered a toy,

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 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 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 representa-
tions 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.

IMPORTANT BUILDING NOTES
●There are two types of screws used in this kit:
Sheet Metal Screws are designated by a number and a
length. For example #6 3/4" [19mm].
This is a number six screw
that is 3/4" [19 mm] long.
Machine Screws are designated by a number,
threads per inch, and a length. For example
4-40 3/4" [19mm].
This is a number four screw
that is 3/4" [19 mm] 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
fi t the part as necessary 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.
●We recommend 30-minute epoxy only, because you will
need the working time 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.

PREPARATIONS
❏ 1. If you have not done so already, remove the major
parts of the kit from the box and inspect for damage. If any
parts are damaged or missing, contact Product Support at
the address or telephone number listed in the “Kit Inspection”
section on page 4.
❏ 2. Remove the tape and separate the elevators from the
stab. Use a covering iron with a covering sock on medium
heat to tighten the covering on the wings, fuselage, etc. if
necessary. Apply pressure over sheeted areas to thoroughly
bond the covering to the wood. Caution: The Factor 3D EP
ARF was designed to be strong where needed, but light weight
for excellent flight performance. Care must be taken when
assembling the plane to avoid damage.
ASSEMBLE THE WINGS
Install the Ailerons
Do the right wing first so your work matches the photos
the first time through.
Install the Aileron Servos and Pushrods
❏ ❏
1. Inside the servo bay a string is taped. Carefully
remove the tape and string from the servo bay. Tie the string
to the servo lead. Pull the string and the servo lead through
the wing. Untie the string from the lead.
❏ ❏ 2. Install the servo into the servo opening. Drill a 1/16"
[1.6 mm] hole though the servo mount, into the wood in the
wing. Install and then remove a servo mounting screw into
each of the holes you have drilled. Apply a drop of thin CA
into the holes to harden the threads. Once the glue has cured
install the servo into the servo opening. Center the servo and
then install a servo arm as shown.The arm should be pointing
towards the wing root.
❏ ❏
3. Drill a 5/64" [ 2 mm ] hole through the hole in the servo
arm as shown.
❏ ❏ 4. Thread a nylon clevis, 20 turns, onto a 6" [152 mm]
wire pushrod.
Hinge Line Hinge Line
Correct Incorrect
Refer to this picture for steps 5-7.
❏ ❏ 5. Cut the
mounting plate from
the control horn.
Attach the clevis in the
outer hole of a nylon
control horn. Place
the control horn in line
with hole you drilled in
the servo arm. When
positioned properly
the control horn will
rest on a hardwood
plate in the aileron.
Mark the location of
the mounting holes
onto the aileron. Drill
a 1/16" [1.6 mm] hole
on the marks, drilling
through the plywood
plate but not through
the top of the aileron.

7
❏ ❏ 6. Install and then remove a #2 3/8" [10 mm] screw
into each of the holes you have drilled. Apply a drop of thin
CA into the holes to harden the threads. Once the glue has
cured, secure the control horn to the aileron with the screws.
❏ ❏ 7. Slide a silicone clevis retainer over the clevis. With
the aileron servo and the aileron centered, mark the aileron
pushrod where it crosses the aileron servo arm. Make a 90°
bend at the mark. Cut the pushrod 3/8" [9.5 mm] past the bend.
Attach the pushrod to the aileron servo arm with a nylon Faslink.
❏ ❏ 8. Locate a 1/8" ½" [ 3 13 mm] nylon pin. Glue it into
the hole at the trailing edge of the root rib. Approximately ¼"
[ 6 mm ] of the pin should extend from the root rib.
❏ 9. Repeat steps 1- 8 for the left wing panel.
ASSEMBLE THE FUSELAGE
Install the Main Landing Gear
❏ 1. Attach the two main landing gear legs to the fuselage
with four 4- 40 3/8" [3 10 mm] screws, #4 lock washers
and #4 flat washers.
You will complete the installation of the wheels and wheel
pants in a later step. Installing the landing gear legs now will
make handling the fuselage easier during the assembly of
the fuselage.
Install the Elevator & Rudder Servos
❏
1. Install a 16" [ 400 mm] servo extension to both the elevator
servo and the rudder servo. Secure the extension to the lead
with tape, a piece of shrink tube (not included) or some other
method to keep them from coming unplugged.
❏ 2. Inside the fuselage there is a string running through the
fuselage from the back to the front.The string is taped in place

8
in the back of the fuselage. Take the string from the back of
the fuselage and pull it through the lower servo opening on
the left side of the fuselage. From the right side of the fuselage
install the elevator servo lead through the servo opening and
out of the fuselage through the rudder servo opening on the
left side of the fuselage.Tie both the rudder and elevator servo
leads with the string.
❏ 3. From the front of the fuselage pull the servo leads
through the fuselage with the string. Tape the servo leads to
the fuselage to prevent them from falling back into the fuselage.
❏ ❏
4. Install the elevator servo into the servo opening on the
right side of the fuselage. Drill a 1/16" [1.6 mm] hole through
the mounting holes of the servo into the servo mounting rails
in the fuselage.
❏ ❏ 5. Install and then remove a servo mounting screw into
each of the holes. Apply a drop of thin CA into the holes to
harden the threads. Once the glue has hardened, install the
servo into the servo opening. Center the servo and then install
a servo arm as shown.
❏ ❏
6. Drill a 5/64" [ 2 mm] hole through the hole in the servo
arm as shown.
❏ 7. Repeat steps 4 - 6 for the rudder servo.
Install the Stab and Elevator
If you have not yet removed the canopy, remove it by sliding
it forward and then lifting the back.
❏ 1. Temporarily install the wing tube into the fuselage and
the wings onto the wing tubes. Secure the wing panels to the
fuselage with the nylon wing bolts.
❏ 2. Temporarily install the horizontal stabilizer into the
opening in the back of the fuselage. Position it so that the
distance from the tip of the wing to the tip of the stab is of
equal distance.

9
❏
3. Once properly positioned mark the sides of the fuselage
onto the top and bottom of the stab with a fine tip felt tip marker.
Remove the stab from the fuselage and cut the covering from
the center of the stab as shown. When cutting the covering
DO NOT CUT INTO THE HORIZONTAL STAB! THIS WILL
WEAKEN THE STRUCTURE. You may want to use the
EXPERT TIP that follows for cutting the covering away.
HOW TO CUT COVERING FROM BALSA
Use a 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 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. Peel off the covering.
❏ 4. Install the elevator into the slot in the back of the fuselage.
Re-install the stab back into the fuselage.
❏ 5. Glue the stab to the fuselage. Check to be sure the
stab is aligned with the wing before the glue dries. Leave the
fuselage undisturbed until the glue dries.

10
❏ 6. Locate six hinges. Insert a T-pin through the center of
each hinge.
❏ 7. Install the hinges into the slots in the elevator and then
slide the elevator onto the stab.
❏ 8. Apply a couple of drops of thin CA glue onto the top
and bottom of each of the hinges. Allow the glue to harden.
After the glue has dried, pull on the elevator to be sure the
hinges are secure.
❏ ❏ 9. Cut the mounting plate from the control horn. Place
the control horn in line with the elevator servo arm. Position the
horn on the elevator the same as was done with the ailerons.
Mark the location of the mounting holes onto the aileron. Drill a
1/16" [1.6 mm] hole on the marks, drilling through the elevator.
Install two 1/16" 3/8" machine screws through the control
horn and the elevator, securing them with the nylon plate on
the top of the elevator.
❏ ❏ 10.Thread a nylon clevis, 20 turns, onto a 6" [152 mm]
wire pushrod.
❏ ❏ 11. Slide a silicone clevis retainer over the clevis. With
the elevator servo and the elevator centered, mark the aileron

11
pushrod where it crosses the aileron servo arm. Make a 90°
bend at the mark. Cut the pushrod 3/8" [9.5 mm] past the
bend. Attach the pushrod to the elevator servo arm with a
nylon Faslink.
❏ 12. Repeat steps 9-11 for the rudder pushrod installation.
Install the Motor, Speed Control
and Receiver
❏ 1. Assemble your motor following the instructions that came
with it. Install the motor to the firewall with four 4-40 3/8" [3
10 mm] machine screws, #4 [ 3 mm] lock washers and #4
[3 mm] flat washers. Be sure to apply a drop of thread locker
to the threads on each screw.
❏
2. Cut a piece of the adhesive-backed hook and loop
fastener to fit the speed control and apply one side of it to
one side of the speed control and the other half to the bottom
of the battery tray in the fuselage. Install the Velcro strap
(without adhesive backing) through the slots in the battery
and around the speed control. Plug the leads from the motor
into the speed control.

12
❏ 3. Cut the remaining adhesive-backed hook and loop
fastener to fit the receiver. Apply the receiver inside the fuselage.
Orient the antenna according to the receiver's instructions.
❏ 4. Plug the servo leads, aileron “Y” harness and the speed
control into the appropriate channels in the receiver.
❏ 5. Test run the motor to be sure the propeller is turning in
the correct direction.
Install the Cowl
❏ 1.There is a small plywood plate inside the fuselage for the
cowl mounting screws. The photo illustrates the approximate
position of the plywood plates.
❏ 2. From the center of the plywood plate draw a line back
1" [ 25 mm] with a felt tip pen.
❏ 3. Slide the cowl onto the fuselage. Slide the spinner back
plate onto the motor shaft. Depending on your brand of motor
you may need to enlarge the hole in the back plate.When the
cowl is properly positioned the distance between the spinner
back plate and the front of the cowl should be 3/32" [2.4 mm].
❏ 4. Using the lines you put on the fuselage as a reference,
drill a 1/16" [1.6 mm] hole through the cowl and into the
plywood plate in the fuselage. Secure the cowl with four 3/32"
5/16" [2.5 8 mm] washer head screws.
❏ 5. Do not install the propeller at this time. For safety, this
will be done after the plane is completed.

13
Install the Wheel and Wheel Pants
❏ ❏
1. Secure the wheel pant to the landing gear with a 2-56
1" [2 25 mm] screw and 2-56 nylon stop nut.
❏ ❏ 2. Slide the wheel onto screw. Install another nylon stop
nut onto the end of the screw to secure the wheel.
❏ ❏ 3. Set the position of the wheel pants and secure the
pant to the landing gear with a 1/16" 1/4" [1.6 6 mm] wood
screw. Do this for both wheel pants.
❏ 3. Locate the parts shown. Install the set screw into the
wheel collar.
❏ 4. Install the nylon bushing into the fuselage.
❏ 5. Assemble the remaining components as shown here.

14
❏ 6. Place the metal bracket against the plywood plate. Drill
a 1/16" [1.6 mm] hole through the holes in the bracket and
into the plywood plate. Secure the bracket to the fuse with
two 1/16" ½" [1.6 13 mm] screws. Insert the nylon pin on
the tail wheel wire into the hole in the bottom of the rudder.
Glue it to the rudder with a couple of drops of thin CA glue.
❏ 7. Slide the tail wheel onto the tail wheel wire and secure
it with the nylon retainer.
Apply the Decals
This photograph and the box photographs show the location
of the decals on the airplane. Refer to these for the exact
placement of the decals. The following tips may be useful for
applying them.
❏ 1. Be certain the model is clean and free from oily fingerprints
and dust. Prepare a dishpan or small bucket with a mixture
of liquid dish soap and warm water—about one teaspoon of
soap per gallon of water. Submerse the decal in the soap and
water and peel off the paper backing. Note: Even though the
decals have a “sticky-back” and are not the water transfer type,
submersing them in soap & water allows accurate positioning
and reduces air bubbles underneath.
❏ 2. Position decals on the model. Holding the decal down,
use a paper towel to wipe most of the water away.
❏ 3. Use a piece of soft balsa or something similar to squeegee
remaining water from under the decal. Apply the rest of the
decals the same way.
GET THE MODEL READY TO FLY
Check the Control Directions
❏ 1.Turn on the transmitter and receiver and center the trims.
If necessary, remove the servo arms from the servos and
reposition them so they are centered. Reinstall the screws
that hold on the servo arms.
❏ 2. With the transmitter and receiver still on, check all the
control surfaces to see if they are centered. If necessary, adjust
the clevises on the pushrods to center the control surfaces.

❏ 3. Make certain that the control surfaces and the throttle
respond in the correct direction as shown in the diagram. If any
of the controls respond in the wrong direction, use the servo
reversing in the transmitter to reverse the servos connected to
those controls. Be certain the control surfaces have remained
centered. Adjust if necessary.

15
Set the Control Throws
Use 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:

We also put exponential into the High rates and the 3D rates to
make the control throws less sensitive around neutral. These
can be set up to your own preference and flying style. We put
20% to 30% in the high rate and 50% to 60% in the 3D rates.
IMPORTANT: The Factor 3D EP 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 Factor 3D EP flies, you would like to
change the throws to suit your taste, that is fine. However,
too much control throw could make the model difficult to
control, so remember, “more is not always better.”
Finish the Model
❏ 1. Insert a flight battery in the fuselage and use the hook
and loop material to hold the battery in position. Do not connect
the battery to the ESC while balancing the model.
❏ 2. Install the propeller and spinner to the motor shaft.
Balance the Model (C.G.)
More than any other factor, the C.G. (center of gravity/
balance point) can have the greatest effect on how a model
flies and could determine whether or not your first flight will
be successful. If you value your model and wish to enjoy it
for many flights, DO NOT OVERLOOK THIS IMPORTANT
PROCEDURE. A model that is not properly balanced may
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 and battery,
landing gear, covering and paint, and the radio system.
❏
1. Use a felt-tip pen or 1/8" [3 mm]-wide tape to accurately
mark the C.G. on the top of the wing at the side of the fuselage.
The C.G. is located 4-1/4" [108mm] back from the leading
edge of the wing at the side of the fuselage.
This is where your model should balance for the first flights.
Later, you may wish to experiment by shifting the C.G. up
to 3/16" [5 mm] forward or 1/4" [6 mm] 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.

16
❏ 2. With the wing attached to the fuselage, all parts of the
model installed (ready to fly) and the battery installed, lift it
at the balance point you marked.
❏ 3. If the tail drops, the model is “tail heavy” and the battery
pack and/or receiver must be shifted forward or weight must
be added to the nose to balance. If the nose drops, the model
is “nose heavy” and the battery pack must be shifted aft or
weight must be added to the tail to balance. If additional weight
is required, use Great Planes (GPMQ4485) “stick-on” lead. A
good place to add stick-on nose weight is to the motor box
(don’t attach weight to the cowl—it is not intended to support
weight). Begin by placing incrementally increasing amounts of
weight on the fuse over the motor box until the model balances.
Once you have determined the amount of weight required, it
can be permanently attached.
Note: Do not rely upon the adhesive on the back of the lead
weight to permanently hold it in place. Over time the adhesive
may soften and cause the weight to fall off. Use #2 sheet
metal screws, RTV silicone or epoxy to permanently hold
the weight in place.
❏ 4. IMPORTANT: If you found it necessary to add any weight,
recheck the C.G. after the weight has been installed.
Balance the Model Laterally
❏ 1. With the wing level, have an assistant help you lift the
model by the engine propeller shaft and the bottom of the
fuse under the TE of the fin. 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 weight to the
other wing tip. An airplane that has been laterally balanced
will track better in loops and other maneuvers.
PREFLIGHT
Identify Your 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 page 19 and place it on or inside your model.
Charge the Batteries
Follow the battery charging instructions that came with your
radio control system to charge the batteries.You should always
charge your transmitter batteries the night before you go flying,
and at other times as recommended by the radio manufacturer.
Charge the motor battery following the instructions that came
with the battery. Be sure to use the appropriate charger that
is recommended for the battery.
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 100 feet 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. The problem may be the location of the
antenna. The antenna should be as far away from the ESC
and battery as possible.
MOTOR SAFETY PRECAUTIONS
Failure to follow these safety precautions may result
in severe injury to yourself and others.
●Get help from an experienced pilot when learning to
operate electric motors.
●Use safety glasses when running electric motors.
●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.
●The motor gets hot! Do not touch it during or right
after operation.
●When working on your plane, remove the propeller if the
motor battery will be connected.
●Always remove the motor battery from the plane
when charging.

17
●Follow the charging instructions included with your charger
for charging LiPo batteries. LiPo batteries can cause
serious damage if misused.
●Never charge LiPo batteries unattended.

9) Under no circumstances may a pilot or other person touch
a powered model in flight; nor should any part of the model
other than the landing gear, intentionally touch the ground,
except while landing.
CHECK LIST
During the last few moments of preparation your mind may
be elsewhere anticipating the excitement of the first flight.
Because of this, you may be more likely to overlook certain
checks and procedures that should be performed before the
model is flown. To help avoid this, a check list is provided to
make sure these important areas are not overlooked. Many
are covered in the instruction manual, so where appropriate,
refer to the manual for complete instructions. Be sure to
check the items off as they are completed (that’s why it’s
called a check list!).
❏
1. Check the C.G. according to the measurements
provided in the manual.
❏
2. Be certain the battery and receiver are securely
mounted in the fuse. Simply stuffing them into place
with foam rubber is not sufficient.
❏
3. Extend your receiver antenna and make sure it has
a strain relief inside the fuselage to keep tension off
the solder joint inside the receiver.
❏
4. Balance your model laterally as explained in
the instructions.
❏
5. Use threadlocking compound to secure critical fasteners
such as the motor screws, wheel collar SHC screws
and screw-lock pushrod connectors, etc.
❏
6. Add a drop of oil to the axles so the wheels will
turn freely.
❏
7. Make sure all hinges are securely glued in place.
❏
8. Reinforce holes for wood screws with thin CA where
appropriate (servo mounting screws, control horn
screws, etc.).
❏
9. Confirm that all controls operate in the correct direction
and the throws are set up according to the manual.
❏ 10. Make sure there are silicone retainers on all the clevises
and that all servo arms are secured to the servos with
the screws included with your radio.
❏ 11. Secure connections between servo wires and
Y-connectors or servo extensions with vinyl tape, heat
shrink tubing or special clips suitable for that purpose.
❏ 12. Make sure any servo extension cords you may have
used do not interfere with other systems (servo arms,
pushrods, etc.).
❏ 13. Balance your propeller (and spare propellers).
❏ 14. Tighten the propeller nut and spinner.
❏ 15. Place your name, address, AMA number and telephone
number on or inside your model.
❏ 16. If you wish to photograph your model, do so before
your first flight.
❏ 17. Range check your radio when you get to the
flying field.

FLYING
The Factor 3D EP ARF is a great-flying model that flies smoothly
and predictably. Factor 3D 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. As you
can see the airplane is a very lightly built structure.This
is big reason for the terrific performance of the model.
Because of the structure it is important that landings
are performed at slow speeds.We recommend the Factor
3D ARF be flown from hard surfaces or very short grass
fields to avoid damage.
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) rapidly vibrates up and down (thus causing the noise).
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 checking all
the servo grommets for deterioration or signs of vibration.
Make certain all pushrod linkages are secure and 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
Only attempt takeoffs and landings from a hard surface or
very short grass. Before you get ready to takeoff, see how
the model handles on the ground by doing a few practice runs
at low speeds on the runway. Hold “up” elevator to keep the
tail wheel on the ground. If necessary, adjust the tail wheel
so the model will roll straight down the runway. If you need
to calm your nerves before the maiden flight bring the model
back into the pits, peak the battery and check all fasteners
and control linkages for peace of mind.
Remember to takeoff into the wind. When you’re ready, point
the model straight down the runway, hold a bit of up elevator
to keep the tail on the ground to maintain tail wheel steering,
and then gradually advance the throttle. As the model gains
speed decrease up elevator allowing the tail to come off the
ground. One of the most important things to remember with
a tail dragger is to always be ready to apply right rudder to
counteract engine torque. Gain as much speed as your runway
and flying site will practically allow before gently applying up
elevator, lifting the model into the air. 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. The
Factor 3D EP ARF with the recommended power system will
only require full throttle in short burst. Most aerobatic flight can
be performed at around 1/3 to 1/2 throttle. If you observe the
flight of some of the best aerobatic pilots, they very seldom
use full throttle.
Take it easy with the Factor 3D EP ARF for the first flight,
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, 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. Mind your battery
power level, but use this first flight to become familiar with your
model before landing. With most electric planes it is best to
have a timer set on your transmitter or a separate timer with
an alarm to alert you when the battery may be getting low.
This will require a few flights before determining the maximum
flight time you can achieve with the batteries.This will prevent
the downwind auto motor cutoff over the end of the flying field.
With the plane properly trimmed you will want to get started
with some aerobatics.This plane is capable of just about every
aerobatic maneuver you can do. Become familiar with the high
and low rate settings before using the 3D rates. If you have
not flown an airplane with 3D rates you should work your way
into these higher 3D rates cautiously. The extreme throws can
stall the airplane if you are not careful. Over controlling could
also result in unwanted snaps. If you have not flown 3D you
might want to consider getting help from an experienced 3D
pilot. When executing down line maneuvers it is important to
use good throttle management. Full power down lines could
result in over stressing of the aircraft.
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, modulating the throttle as necessary to
maintain your glide path and airspeed. 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.When you’re ready to make your landing flare

and the model is a foot or so off the deck, smoothly increase
up elevator until it gently touches down. Once the model is
on the runway and has lost flying speed, hold up elevator to
place the tail on the ground, regaining tail wheel control. Try
to land slowly and gently.
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, check your altitude, mind the wind direction (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!
