During the course of building your model, we

suggest you use a soft base for the building surface.

Such things as a foam stand, large piece of

bedding foam or a thick bath towel will work well

and help protect the model from damage during

assembly. This is not shown in the instructions

to provide the greatest detail in the photos.

When referencing directions (up, down, left,

right top and bottom), these directions are in

relationship to the pilot sitting in the cockpit

of the aircraft, unless noted otherwise.

Aileron Servo Installation

Required Parts

Wing panel (right and left)
Servo with hardware (2)

Required Tools and Adhesives

Thin CA Phillips screwdriver: #1

 1. Use a #1 Phillips screwdriver to thread a

servo mounting screw into each of the holes to
cut threads in the surrounding wood. Remove the
screw before moving to the next step.

 3. Insert the servo lead into the wing. Hold the

wing with the tip in the air and guide the lead out
of the wing at the wing root. Secure the servo in
the wing using the screws provided with the servo
and a #1 Phillips screwdriver. The output shaft of
the servo faces toward the aileron as shown.

Before starting the assembly of your model, we

recommend preparing your radio system for

installation. This includes charging the transmitter and

receiver batteries, as well as centering the trims and
sticks on your transmitter. If using a computer radio,

make sure to reset a model memory and name it for

this particular model. We also recommend binding

the transmitter and receiver at this time, following

the instructions provided with your radio system.

 We highly recommend re-binding the radio

system once all the control throws are set. This will

keep the servos from moving to their endpoints

until the transmitter and receiver connect.

 2. Apply 1–2 drops of thin CA in each of the holes

to harden the surrounding wood. This will prevent
the screws from stripping surrounding wood.

 4. Repeat steps 1 through 3 to install the remaining

aileron servo.

5E-flite Twist 3D 480 ARF Assembly Manual

Hinging the Ailerons

Required Parts

Wing panel (right and left)
Aileron (right and left
CA hinge (8)

Required Tools and Adhesives

Thin CA T-pins
Pin vise Drill bit: 1/16-inch (1.5mm)

 1. Use a pin vise and 1/16-inch (1.5mm) drill bit

to drill a hole in the center of each hinge slot in the
aileron and wing to create a tunnel for the CA to
wick into. This will allow the CA to penetrate the
hinge, creating a better bond between the hinge
and surrounding wood.

 3. Insert the hinges in the ailerons. The T-pin should

rest on the edge of the aileron bevel.

 4. Slide the aileron back into position. Make sure the

tip of the aileron is flush with the tip of the wing.

 5. Remove the T-pins from the hinges. Saturate

each hinge with thin CA. Apply CA to both the top
and bottom of the hinge.

Do not use CA accelerator when gluing the hinges.

The CA must be allowed to soak into the hinge for the

best bond between the hinge and surrounding wood.

If you are in a humid environment, it is possible that

after the CA cures, a white “fog” will be visible. In

most cases, this can be wiped off with acetone or CA

debonder on a paper towel. In the event that the fog

 2. Place a T-pin in the center of each of the five

hinges. This will center the hinges equally in the
aileron and wing when they are installed.

Placing a #11 hobby blade between the aileron
leading edge and wing trailing edge to position

the aileron will result in a nice free moving

hinge for 3D throws without any binding.

6 E-flite Twist 3D 480 ARF Assembly Manual

forms UNDER the transparent covering, often times a

heat gun can be used to carefully heat the covering to

minimize or eliminate the appearance of the CA fog.
If accelerator is used to cure the CA, the fog that forms
will likely be permanent and this method will not work.

 6. Once the CA has cured, gently pull on the

control surface and wing to make sure the hinges
are glued securely. If not, apply CA to those hinges
that are not glued and recheck. Move the aileron
through its range of motion several times to break
in the hinges. This will reduce the initial load on the
servo when it is attached for the first time.

Aileron Linkage Installation

Required Parts

Wing assembly (right and left)
Pushrod connector (2)
Transmitter Receiver
Flight battery 3D servo horn
Electronic speed control
Nylon control horn with backplate (2)

2.0mm x 170mm pushrod with Z-bend (2)

Required Tools and Adhesives

Thin CA Pin vise
Side cutters Hex wrench: 1.5mm
Toothpick Phillips screwdriver: #0
Drill bit: 5/64-inch (2mm)

 1. Insert the control horn in the slot in the aileron.

 2. Slide the control horn backplate over the end

of the control horn from the opposite side of the
control surface. Snap the backplate so the horn is
held tight against the control surface. Apply 2–3
drops of thin CA to the top and bottom of the horn
backplate to keep it from accidentally coming loose
in flight.

 7. Repeat steps 1 through 6 to hinge the

remaining aileron.

 3. Use a #0 Phillips screwdriver to remove the

servo included with the servo. Set the screw aside
in a safe location. Place a long 3D servo horn
on the servo. Use the radio system to center the
aileron servo. Make sure to position the horn so
it is parallel to the hinge line. If the horn can’t be
installed parallel, use the sub-trim feature of the
radio system to fine-tune the position of the horn.
Use side cutters to remove the side of the horn
facing the root of the wing.

7E-flite Twist 3D 480 ARF Assembly Manual

 4. Use a pin vise and 5/64-inch (2mm) drill bit

to enlarge the hole in the arm that is 3/4 inch
(19mm) from the center of the arm. Attach the
pushrod connector to the servo arm. The included
washers may be used to reduce the amount of play
in the connector when it is installed. Tighten the nut
so that it is secure on the arm but is not too tight.
There should be a small amount of play between
the arm and the connector, and the connector
should be able to rotate freely on the arm. Use a
very small amount of medium CA on a toothpick
to secure the nut to the bottom of the connector
threads. Do not use thin CA for this step as it can
wick through the nut and glue the connector to the
arm. Make sure the connector still rotates freely in
the arm after the glue is cured.

Always use threadlock on metal-to-metal fasteners

to prevent them from vibrating loose.

 6. The pushrod wire will pass through the hole in

the micro screw-lock connector. With the servo
centered, secure the horn to the servo using the
screw provided with the servo and a #0 Phillips
screwdriver. With the control surface and servo
centered, use a 1.5mm hex wrench to tighten the
setscrew in the connector to secure the pushrod
wire. Use side cutters to trim the pushrod so it is
1/4 inch (6mm) past the connector as shown.

up at the rear. The rear is held in position using a
magnet and the front has tabs that lock the hatch to
the fuselage. Set the hatch aside in a safe location
until later.

Always use threadlock on metal-to-metal fasteners.

 2. Prepare your motor by attaching the mount to the

motor using the hardware provided.

 4. Attach the landing gear to the fuselage using

two M3 x 10 socket head bolts, two M3 washers
and two M3 lock washers. Slide the lock washer on
the bolt, then the washer, before securing the gear.
Use a 2.5mm hex wrench to tighten the bolts.

There are multiple holes located on the firewall to

mount a variety of motors. The Park 480 will mount

with a 45 degree orientation of the X-mount and

the Park 450 will mount with a vertical/horizontal

orientation as shown in the following photos.

9E-flite Twist 3D 480 ARF Assembly Manual

 3. Install the M3 blind nuts by using an M3 x 10

socket head bolt and M3 washer. Use a 2.5mm
hex wrench to tighten the bolt, drawing the prongs
of the blind nut into the back side of the firewall.

Always use threadlock on metal-to-metal fasteners

to prevent them from vibrating loose.

 4. Secure the motor to the firewall using four M3

x 10 socket head bolts, four M3 washers and four
M3 lock washers. Tighten the bolts using a 2.5mm
hex wrench.

If using all E-flite components, match the

wire colors between the ESC and motor

to ensure correct motor direction.

 5. Connect the leads from the motor to the leads

from the speed control. Cut a small piece of hook
and loop tape to secure the speed control inside
the fuselage as shown. Neatly tuck the motor leads
so the battery can be installed. Route the lead to
the receiver under the battery tray so it can be
retrieved when installing the receiver.

 6. Route the lead from the speed control through

the fuselage and plug it into the throttle channel of
the receiver. Cut a small section of hook and loop
tape to secure the receiver in the fuselage. Set the
receiver back from the wing tube so the aileron
servo leads can be inserted into the fuselage
without interference from the receiver.

 7. Apply a piece of hook and loop tape to the

battery tray. Insert the hook and loop strap through
the slot in the battery tray. Make sure not to get the
motor and receiver leads inside the straps as they
may come accidentally disconnected when you
strap down the battery.

10 E-flite Twist 3D 480 ARF Assembly Manual

 8. Apply the matching hook and loop tape from

step 5 to the bottom of the battery. This will keep
the battery from moving forward or aft in the
fuselage. Use the hook and loop strap to secure the
battery to the battery tray.

 9. Turn on the transmitter. Connect the battery

to the power lead of the speed control. Check
the rotation of the motor to make sure it rotates
counterclockwise when viewed from the front of the
fuselage. If not, swap any two of the motor leads to
correct the direction of rotation.

 10. Use the propeller adapter to secure the

propeller to the motor. Slide a 2.5mm hex wrench
through the hole in the adapter to tighten it,
securing the propeller.

Wing Installation

Required Parts

Assembled wing panel (right and left)

M3 washer (2)

Required Tools and Adhesives

Hex wrench: 2.5mm
Hobby knife with #11 blade

 1. Slide the carbon fiber wing tube into the socket

in the wing panel. The socket has a cap on it, so
do not force the wing tube in the wing any farther
than it will easily slide.

Always balance your propeller. An unbalanced
propeller can cause vibrations to be transmitted

into the airframe, which could damage the

airframe or other components, as well as

produce unwanted flight characteristics.

 2. Slide the tube into the socket in the fuselage.

Make sure to guide the lead for the aileron servo in
the fuselage when positioning the wing.

a 2.5mm hex wrench to tighten the screw. Plug the
aileron servo into the receiver if you are preparing
your model for flight.

 4. Repeat steps 2 and 3 to install the second wing

panel.

Stabilizer Installation

Required Parts

Fuselage assembly Stabilizer

Required Tools and Adhesives

Thin CA Ruler
Hobby knife with #11 blade
Medium grit sandpaper

It is important to check the alignment of the

stabilizer in relationship to the wing. Not doing

so may cause your airplane to require excessive

amounts of trim to correct for poor alignment,

resulting in poor flight performance.

When cutting through the covering, use a new

#11 blade and light pressure to avoid cutting into

the underlying wood, which could weaken the

underlying structure, causing it to fail in flight. We

also recommend using a hot knife to melt through

the covering to help reduce damaging the wood.

 1. Remove the elevators from the stabilizer. Set the

elevators, joiner wire and four CA hinges aside
until later. Align a ruler tangent to the edges of the
lightening holes in the stabilizer center section and
use this as a guide to cut the covering for removal,
erring to the inside slightly. Remove covering from
both the top and bottom of the stabilizer.

 2. Fit the joiner wire into the elevators. Check to

make sure the elevators are in alignment with each
other by placing the assembly on a flat surface. It
may be necessary to bend the joiner wire slightly to
align both elevator halves. Make sure to mark the
elevators and joiner wire so they can be oriented
later in this section of the manual.

Align with top of wing

medium grit sandpaper to roughen the joiner rod
where it will contact the elevators.

 4. Place the joiner wire in the slot for the stabilizer.

Once the joiner is in position, slide the stabilizer
into the slot in the fuselage.

 5. Slide the stabilizer into the slot at the rear of the

fuselage. Measure the distance from each stabilizer
tip to the fuselage centerline to make sure the
stabilizer is centered.

 6. Measure the distance from each stabilizer tip to

the outside corner of the aileron hinge line. These
measurements must match as close as possible.
Adjust the position of the stabilizer if necessary to
position the stabilizer.

 7. Stand back 8–10 feet (2–3 meters) and view

the aircraft from the rear. Check the alignment
between the wing and stabilizer. They must be
equal distance on each side as shown. If not,
lightly sand the stabilizer saddle to correct any
alignment problems.

Do not use CA accelerator when gluing the

stabilizer to the fuselage. The CA must be

allowed to soak into the fuselage and stabilizer

for the best bond between the two surfaces.

 8. Recheck recheck all of your measurements

to make sure everything is in alignment. Once
satisfied, wick thin CA into the joint between the
stabilizer and fuselage. Allow the CA to fully cure
before proceeding. Use care not to accidentally
glue the joiner wire.

Required Tools and Adhesives

Felt-tipped pen Thin CA
Square Hobby knife with #11 blade
Straight edge

The wing can be removed at this time to allow

the fuselage to be easier to manage during the

remainder of the assembly of your model.

 1. Remove the rudder from the fin. Set the rudder

and two CA hinges aside until later. Place the fin in
the slot on the top of the fuselage. Use a felt-tipped
pen to trace the outline of the fuselage on the
bottom of the fin.

 2. Remove the fin from the fuselage. Use a hobby

knife and #11 blade to trim the covering below
the lines drawn in the previous step by 1/16 inch
(1.5mm). Remove the covering, exposing the bare
wood. Leave a 1/4-inch (6mm) piece of covering
at the hinge line to add a finished look to your
model when the fin is installed. The lines can be
removed using a paper towel and rubbing alcohol.

 3. Place the fin back in the slot on top of the

fuselage. Use a square to make sure the fin is
positioned 90 degrees to the stabilizer. If not,
lightly sand the inside of the filler blocks that form
the slot to correct its alignment.

 4. Use a straight edge to make sure the fin is

aligned with the rear of the fuselage.

Do not use CA accelerator when gluing the

fin to the fuselage. The CA must be allowed

to soak into the fuselage and fin for the

best bond between the two surfaces.

 5. Once aligned, wick thin CA into the joint

between the fin and fuselage. Allow the CA to fully
cure before proceeding.

When cutting through the covering, use a new

#11 blade and light pressure to avoid cutting into

the underlying wood, which could weaken the

underlying structure, causing it to fail in flight. We

also recommend using a hot knife to melt through

the covering to help reduce damaging the wood.

a better bond between the hinge and surrounding
wood. Prepare all of the hinge slots for the vertical
fin, rudder, horizontal stabilizer, and elevators.

 2. Place a T-pin in the center of four CA hinges.

Insert the hinges into the elevator as shown. The
T-pin will rest on the edge of the bevel of the
control surface. Prepare both elevators at this time.

 3. Mix a small amount of 5-minute epoxy and

apply it to the joiner wire and into the hole and slot
in the elevator using a toothpick.

 4. Place both elevators into position once the epoxy

has been applied. Use a paper towel and rubbing
alcohol to remove any excess epoxy before it
begins to cure. Make sure to check the alignment
of the elevators to make sure they are in alignment
while the epoxy cures.

 5. Remove the T-pins from the hinges. Position

the elevators so they move freely without the
counterbalances hitting the ends of the stabilizer.

15E-flite Twist 3D 480 ARF Assembly Manual

 6. Saturate each of the hinges with thin CA on both

the top and bottom of the hinge. Set the assembly
aside to cure.

Do not use CA accelerator when gluing the hinges.

The CA must be allowed to soak into the hinge for the

best bond between the hinge and surrounding wood.

 7. Once the CA and epoxy has cured, check

that all the hinges are secure by gently trying to
separate the elevators from the stabilizer. If any
hinges are loose, re-apply CA to the loose hinges.
Break in the hinges by working the stabilizer up
and down a number of times. This will reduce
the initial load on the servo when the servo is
connected for the first time.

 8. Place a drop of light machine oil so it wicks into

the hinge knuckle along the tail gear wire. This
will keep the epoxy from entering the knuckle and
gluing the wire inside of it.

 9. Fit the tail wheel assembly into the slot at the

bottom of the rudder. The bushing will rest in fully
in the slot. If not, use a hobby knife and #11 blade
to trim the slot until the knuckle fits. Once fit, lightly
sand the wire where it enters the rudder. Use a
small amount of 5-minute epoxy to glue the tail
wheel into position in the rudder.

 10. Use a pin vise and 1/16-inch (1.5mm) drill

bit to drill a hole in the center of each hinge
slot to create a tunnel for the CA to wick into.
This will allow the CA to penetrate the hinge,
creating a better bond between the hinge and
surrounding wood. Prepare the rudder and
vertical fin at this time.

 11. Insert the hinges in the fin. The T-pin will rest

flat on the trailing edge of the fin. Use a hobby
knife to remove the covering from the slot at the
bottom of the fuselage for the tail wheel bearing.

16 E-flite Twist 3D 480 ARF Assembly Manual

 12. Slide the rudder into position, guiding the tab

on the tail wheel knuckle into the slot at the bottom
of the rudder.

 14. Once the CA has cured, gently pull on the

control surfaces and fin to make sure the hinges
are glued securely. If not, apply CA to those hinges
that are not glued and recheck.

Rudder and Elevator Servo Installation

Required Parts

Fuselage Servo with hardware (2)
Flight battery Pushrod connector (2)
Transmitter
9-inch (228mm) servo extension (2)
Nylon control horn with backplate (2)

2.0mm x 170mm pushrod with Z-bend (2)

Required Tools and Adhesives

Medium CA Thin CA
Side cutters String or dental floss
Hex wrench: 1.5mm
Pin vise Phillips screwdriver: #0, #1
Drill bit: 5/64-inch (2mm)

 13. Check to make sure the counterbalance can

move freely without hitting the top of the fin.
Remove the t-pins from the hinges and apply
thin CA to each of the hinges. Make sure to fully
saturate both sides of the hinges.

Do not use CA accelerator when gluing the hinges.

The CA must be allowed to soak into the hinge for the

best bond between the hinge and surrounding wood.

 15. Move the rudder through its range of motion

a number of times to break in the hinges. This will
reduce the initial load on the servo when the servo
is connected for the first time.

 1. Use string or dental floss to secure a 9-inch

(228mm) servo extension to one of the servos.

17E-flite Twist 3D 480 ARF Assembly Manual

 2. Fit the servo in the opening on the left side of

the fuselage for the elevator with the output shaft
facing the rear of the fuselage. Guide the lead
into the fuselage toward the receiver. Plug the lead
into the elevator port of the receiver. Use a #1
Phillips screwdriver to thread a servo mounting
screw into each of the holes to cut threads in
the surrounding wood. Remove the screw before
moving to the next step.

 3. Apply 1–2 drops of thin CA in each of the holes

to harden the surrounding wood. This will harden
the threads so the screws do not easily strip the
surrounding wood.

 4. Secure the elevator servo in the fuselage using

the screws provided with the servo and a #1
Phillips screwdriver.

 5. Use a pin vise and 5/64-inch (2mm) drill bit

to enlarge the hole in the arm that is 3/4 inch
(19mm) from the center of the arm. Attach the
pushrod connector to servo arm. The included
washers may be used to reduce the amount of play
in the connector when it is installed. Tighten the nut
so that it is secure on the arm, but is not too tight.
There should be a small amount of play between
the arm and the connector, and the connector
should be able to rotate freely on the arm. Use a
very small amount of medium CA on a toothpick
to secure the nut to the bottom of the connector
threads. Do not use thin CA for this step as it can
wick through the nut and glue the connector to the
arm. Make sure the connector still rotates freely in
the arm after the glue is cured.

 6. Remove the attached servo horn from the servo

using a #0 Phillips screwdriver. Attach the servo
arm prepared in step 7 on the elevator servos
using the screw removed from the servos and a #0
Phillips screwdriver.

 7. Pass the Z-bend in the elevator pushrod through

the center hole (inner hole for the rudder) of the
control horn.

18 E-flite Twist 3D 480 ARF Assembly Manual

 8. Slide the pushrod into the hole in the pushrod

connector. Insert the control horn in the slot in
the elevator.

 9. Slide the control horn backplate over the end

of the control horn from the opposite side of the
control surface. Snap the backplate so the horn is
held tight against the control surface. Apply 2–3
drops of thin CA to the backplate where it contacts
the control horn to keep it from accidentally coming
loose in flight.

Always use threadlock on metal-to-metal fasteners

to prevent them from vibrating loose.

 10. Use the radio system to center the elevator

servo. Center the elevator so it is aligned with
the stabilizer. Tighten the setscrew in the pushrod
connector using a 1.5mm hex wrench to secure
the pushrod wire. Use side cutters to trim the
excess length of wire 1/4 inch (6mm) beyond the
connector as shown.

Canopy Installation

Required Parts

Fuselage assembly Canopy
Pilot (optional)

Required Tools and Adhesives

Low-tack tape Canopy glue

 1. (Optional Pilot) Use silicone adhesive to glue the

pilot figure in the cockpit. The pilot will be centered
13/8 inches (52mm) forward of the back of the
cockpit as shown.

 11. Repeat steps 1 through 10 to install the rudder

servo and hardware.

 2. Thoroughly clean the inside of the canopy with

window cleaner and a paper towel. Avoid touching
the inside of the canopy after it has been cleaned
to prevent fingerprints and debris from being
inaccessible after the canopy is glued on.

19E-flite Twist 3D 480 ARF Assembly Manual

 3. Apply a thin bead of canopy glue around the

perimeter of the canopy.

Center of Gravity

Required Parts

Assembled airframe

Required Tools and Adhesives

Felt-tipped pen Ruler
Phillips screwdriver: #2
Balancing stand (optional)

An important part of preparing the aircraft for flight is
properly balancing the model.

CAUTION: Do not inadvertently skip this step or

property damage and injury could occur.

 3. When balancing your model, support the plane

upright at the marks made on the bottom of the
wing with your fingers or a commercially available
balancing stand. This is the correct balance
point for your model. Make sure your model is
assembled and ready for flight before balancing.

 4. Use low-tack tape to hold the canopy in position

on the fuselage as shown with the front edge of the
painted rear portion aligned with the front edge of
the turtle deck. Make sure it is centered left-to-right
on the fuselage.

To give your airplane a professional appearance,

apply the striping tape around the edge of the

canopy. Work slowly, pulling the tape to stretch

it around the curves at the front of the canopy.

 1. Assemble your model in preparation for flight,

making sure the wing is on securely and the motor
battery is installed as instructed in this manual.

 2. The recommended Center of Gravity (CG)

location for your model is 3
back from the leading edge of the wing as
shown with the battery pack installed. Mark the
location of the CG on the bottom of the wing
with a felt-tipped pen.

1

/2 inches (89mm)

Adjust the motor battery as necessary so the model is

level or slightly nose down. You should find the CG to

be very close with the battery installed as shown in this

manual. Mark the location of the battery on the battery

tray using a felt-tipped pen so it can be returned to this

position if it is removed from your model.

After the first flights, the CG position can be adjusted

for your personal preference.

20 E-flite Twist 3D 480 ARF Assembly Manual

Control Throws

 1. Turn on the transmitter and receiver of your

model. Check the movement of the rudder using
the transmitter. When the stick is moved right,
the rudder should also move right. Reverse the
direction of the servo at the transmitter if necessary.

 2. Check the movement of the elevator with the

radio system. Moving the elevator stick toward
the bottom of the transmitter makes the airplane
elevator move up.

 3. Check the movement of the ailerons with the

radio system. Moving the aileron stick right makes
the right aileron move up and the left aileron
move down.

 4. Use a ruler to adjust the throw of the elevator,

ailerons and rudder. Adjust the position of
the pushrod at the control horn to achieve the
following measurements when moving the sticks to
their endpoints.

Measurements are taken at the

widest point on the surface.

ELEVATOR

High Rate (100%) (30% Exponential)

Up 2.75 inch (70.0mm)
Down 2.75 inch (70.0mm)

AILERON

High Rate (100%) (30% Exponential)

Up 2.00 inch (51.0mm)
Down 2.00 inch (51.0mm)

Low Rate (25% Exponential)

Up 1.25 inch (32.0mm)
Down 1.25 inch (32.0mm)

RUDDER

High Rate (100%) (30% Exponential)

Right 1.50 inch (38.0mm)
Left 1.50 inch (38.0mm)

Low Rate (20% Exponential)

Right 2.75 inch (70.0mm)
Left 2.75 inch (70.0mm)

These are general guidelines measured from our own
flight tests. You can experiment with higher rates to
match your preferred style of flying.

Travel Adjust and Sub-Trims are not listed

and should be adjusted according to each

individual model and preference.

NOTICE: Always re-bind the radio system

once all the control throws are set. This will

keep the servos from moving to their endpoints

until the transmitter and receiver connect.

Preflight

Check Your Radio

Before going to the field, make sure your batteries

are fully charged per the instructions included with

your radio. Charge the transmitter and motor battery

for your airplane. Use the recommended charger

supplied with your particular radio system, following

the instructions provided with the radio. In most

cases, the radio should be charged the night before

going out flying.

Before each flying session, be sure to range check your

radio. See your radio manual for the recommended

range and instructions for your radio system. Each

radio manufacturer specifies different procedures for

their radio systems. Next, run the motor. With the

model securely anchored, check the range again. The

range test should not be significantly affected. If it

is, do not attempt to fly! Have your radio equipment

checked out by the manufacturer.

Double-check that all controls (aileron, elevator, rudder

and throttle) move in the correct direction.

Check the radio installation and make sure all the

control surfaces are moving correctly (i.e., the correct

direction and with the recommended throws).

Check all the control horns, servo horns, and clevises

to make sure they are secure and in good condition.

Low Rate (25% Exponential)

Down 1.25 inch (32.0mm)

21E-flite Twist 3D 480 ARF Assembly Manual

Range Test Your Radio

Before each flying session, and especially with a new
model, it is important to perform a range check. It
is helpful to have another person available to assist
during the range check. If you are using a Spektrum™
transmitter, please refer to your transmitter’s manual for
detailed instructions on the range check process.

 1. With the model resting on the ground, stand 30

paces (approximately 90 feet) away from the model.

 2. Face the model with the transmitter in your

normal flying position. Be sure the throttle is in the
full down position and plug the flight battery into
the speed control.

 3. As you move the controls, watch to be sure the

airplane’s motor and controls operate smoothly.
You should have total control of the model at 30
paces (90 feet).

 4. If control issues exist, call the appropriate

Horizon Product Support office (see addresses
listed in the Warranty Services section of this
manual) or go to horizonhobby.com to find a local
Spektrum distributor in your country for service
when using a Spektrum radio system.

Flying Your Model

The Twist 3D 480 shares many of the same flying
qualities of its larger brethren; however, due to its
small size, very low weight and light wing loading, it
is a very capable 3D performer that can be unleashed
practically anywhere!

Before arriving to the field, verify that the airplane
balances within the range specified here in the
manual, as well as control throws and direction have
been set. Once you have arrived to the field, install
your battery and reconfirm that everything is still
in good order. Taxi out to the runway and line up
with the centerline, facing into the wind. You’ll find
that even though the landing gear is a conventional
arrangement, due to the long tail moment, taxiing
is very easy. Once aligned with the runway, set the
throttle trim that the propeller is spinning at a very
low RPM; this will be your flight idle and will be very
important during 3D flight. Smoothly increase the
throttle and use small rudder corrections to keep the
airplane tracking straight down the runway. It will
lift off very quickly due to the low wing loading and
high power. Climb to a comfortable altitude and trim
the airplane to fly hands off at around half throttle.
Limit your use of higher throttle for maneuvering. Due
to the large control surface area, flutter is possible
at higher airspeeds, and this can lead to a crash if
you’re not careful.

You’ll find that the airplane is quite capable of a full
battery of 3D maneuvers; torque rolls, harrier rolls,
waterfalls, you name it and the Twist 3D 480 will
deliver with gusto. After your initial flights, you can
adjust the CG to suite your flying style. You’ll find that
this little dynamo’s flight envelope is limited only by
your imagination!

You’ll want to setup for landing before your battery

gets too low (although the airplane is very easy to fly

dead stick!). Begin by entering the pattern downwind

at about half throttle. Once abeam of your touchdown

point, slowly reduce power and allow the airplane to

descend. You need not fly a base and final leg, simply

make a descending 180-degree pattern to line up with

the runway. Remember to use the throttle to control

altitude and elevator to control airspeed. Once you

have the runway made, slowly come off the throttle

completely and allow the airplane to settle in for a

nice, three point landing. Rollout will be short, because

you won’t be moving very quickly at touchdown.

Congratulations! You have just flown your Twist 3D

480 ARF! We hope you enjoy this model as much as

we do. Now what are you waiting for? Get back out

there and do it again!

22 E-flite Twist 3D 480 ARF Assembly Manual

Daily Flight Checks

 1. Check the battery voltage of the transmitter

battery. Do not fly below the manufacturer’s
recommended voltage. To do so may cause your
aircraft to crash.

When you check these batteries, ensure you have the

polarities correct on your expanded scale voltmeter.

 2. Check all hardware (linkages, screws, nuts,

and bolts) prior to each day’s flight. Be sure that
binding does not occur and that all parts are
properly secured.

 3. Ensure all surfaces are moving in the

proper manner.

 4. Perform a ground range check before each

day’s flying session.

 5. Prior to starting your aircraft, turn off your

transmitter, then turn it back on. Do this each time
you start your aircraft. If any critical switches are
on without your knowledge, the transmitter alarm
will sound a warning.

 6. Check that all trim levers are in the

proper location.

 7. All servo pigtails and switch harness plugs

should be secured in the receiver. Make sure the
switch harness moves freely in both directions.
