The nimble Leader 480 park flyer is a fun-to-fly
sport plane that is ideal for anyone interested in
precision aerobatics. Its light wing loading will put any
intermediate pilot at ease when flying the slow side of
the envelope. But if you really want to wring it out, its
symmetrical airfoil and classic pattern plane lines will
allow you to fly precision aerobatics with the best of
them.

Assembly is so simple, you could easily have it flight­ready in a single evening. Plus, it’s small enough you
can put it in the backseat or trunk of your car and fly it
most anywhere park flyers are allowed.

Before beginning the assembly of your model, remove
each part from its bag for inspection. Closely inspect
the fuselage, wing panels, rudder and stabilizer for
damage. If you find any damaged or missing parts,
contact the place of purchase.

If you find any wrinkles in the covering, use a heat gun
(HAN100) and covering glove (HAN150) or covering
iron (HAN101) with a sealing iron sock (HAN141) to
remove them. Use caution while working around areas
where the colors overlap to prevent separating the
colors.

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.

 3. 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.

 4. 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.

 5. Once the stabilizer has been aligned to the wing,

use a felt-tipped pen to trace the outline of the
fuselage on the bottom of the stabilizer.

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.

Vertical Fin Installation

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 underlying wood.

 6. Remove the stabilizer from the fuselage. Use a

hobby knife and #11 blade to trim the covering

inside the lines drawn in the previous step by 1/16-

inch (1.5mm). Remove the covering, exposing the

bare wood. The lines can be removed using a

paper towel and rubbing alcohol.

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.

 7. Place the stabilizer back on the fuselage. Recheck

the alignment. Wick thin CA into the joint between
the stabilizer and fuselage. Allow the CA to fully
cure before proceeding.

 3. 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. The lines can be removed using a paper

towel and rubbing alcohol.

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

fuselage. Use a square to make sure the fin is
positioned 90-degrees to the stabilizer. If not, lightly
sand the exposed wood on the bottom of the fin to
correct its alignment.

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

Rudder and Elevator Installation

Required Parts

Fuselage assembly Rudder
Elevator Control horn with backplate (2)
CA hinge (7)

Required Tools and Adhesives

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

 1. 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 fin at this time.

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

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

 2. Place T-pin in the center of each of the three rudder

(or four elevator) hinges. This will center the hinges
equally in each surface when they are installed.

19E-flite Leader 480 ARF Assembly Manual

 3. Insert the hinges in the rudder (or elevator).

The T-pin will rest on the edge of the bevel of the

control surface.

 4. Slide the rudder (or elevator) into position. Make

sure the tip of the control surface is aligned with the

tip of the fixed surface.

 5. Saturate each hinge with thin CA. Apply CA to

both side 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.

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

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

 7. 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 during your
first flights.

 8. Pass the Z-bend in the rudder (or elevator) pushrod

through the outer hole of the control horn.

20 E-flite Leader 480 ARF Assembly Manual

 9. Insert the control horn in the slit in the rudder

(or elevator).

 10. 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

tightly in position. 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.

Before gluing the backplate in position, trim the
front edge of the backplate so it does not cause

binding in extreme throws. Temporarily snap the

backplate into position and mark the backplate

along the bevel with a felt tipped pin. Remove

the backplate and use side cutters to trim the

backplate. Use sandpaper to sand the backplate

to its to final shape before gluing it in position.

 12. Repeat steps 1 through 11 to install the elevator

and associated hardware.

Always use threadlock on metal-to-metal fasteners

to prevent them from vibrating loose.

 11. Use the radio system to center the rudder servo.

Center the rudder so it is aligned with the fin (or
the elevator to the stabilizer). Tighten the screw in
the pushrod connector to secure the pushrod wire.
Use side cutters to trim the excess length of wire that
extends beyond the connector as shown.

Required Parts

Fuselage assembly Motor battery
Hook and loop strap (not included) (2)
Hook and loop tape (not included)

 1. Secure the motor battery in the fuselage using two

hook and loop straps (not included). We recommend

using hook and loop tape between the battery and

battery tray to keep the battery from sliding on the

tray during flight.

Required Parts

Canopy Pilot (optional)
Balsa stiffener (2)

Required Tools and Adhesives

Felt-tipped pen Ruler
Razor saw Medium CA
Sanding block Medium grit sandpaper
Hobby knife with #11 blade

 1. Use a felt-tipped pen to mark the pilot 1/2-inch

(13mm) up from the bottom as shown.

 3. Remove the balsa plate from the inside of the

portion of the pilot trimmed in the previous step. Fit
the plate into the bottom of the pilot. You may need
to lightly sand the plate to fit. Once fit, use medium
CA to glue the plate in the pilot. Allow the CA to fully
cure before proceeding.

 2. Use a razor saw to trim the pilot along the line

Make sure not to wrap the hook and loop strap

around any wires or pushrods. Wrapping it
around the steering pushrod will increase the
load on the rudder servo, which could cause

the servo to fail due to the increased loads.

22 E-flite Leader 480 ARF Assembly Manual

made in the previous step. Use a sanding block and
medium grit sandpaper to smooth the bottom of the
pilot flat.

 4. Use medium CA to glue the two balsa stiffeners to

the bottom of the pilot. These will keep the pilot from
falling into the canopy, and provide a way to secure
the pilot.

 5. Use a hobby knife and #11 blade to remove

Balancing Stand

the covering from the canopy. Test fit the pilot into
the canopy. It may be necessary to lightly sand to
opening to fit the pilot.

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.

 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 33/8 to 33/4 inches (85
to 95mm) back from the leading edge of the wing
as shown with the battery pack installed. Mark the
location of the CG on the top of the wing with a
felt-tipped pen.

 3. When balancing your model, support the plane

inverted at the marks made on the top 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.

Adjust the motor battery as necessary so the model is
level or slightly nose down. This is the correct balance
point for your model. 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.

 6. Once satisfied with the fit, use medium CA to glue

the pilot in the canopy. Apply the glue to the stiffeners
to keep the pilot in the canopy.

After the first flights, the CG position can be adjusted
for your personal preference.

23E-flite Leader 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.

Elevator High Rate (100%) (30% Exponential)

Up 23/32-inch (18mm)
Down 25/32-inch (20mm)

Elevator Low Rate (20% Exponential)

Up 5/16-inch (8mm)
Down 11/32-inch (9mm)

Rudder High Rate (100%) (30% Exponential)

Right 13/16-inch (30mm)
Left 13/16-inch (30mm)

Rudder Low Rate (20% Exponential)

Right 25/32-inch (20mm)
Left 25/32-inch (20mm)

Measurements are taken at the inner or

widest point on the control surface.

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. Always install the control

horns 90-degrees to the servo centerline. Use

sub-trim as a last resort to center the servos.

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.

Preflight

Check Your Radio

Before going to the field, be 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, don’t 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.

Aileron High Rate (100%) (40% Exponential)

Up 25/32-inch (20mm)
Down 25/32-inch (20mm)

Aileron Low Rate (33% Exponential)

Up 19/32-inch (15mm)
Down 19/32-inch (15mm)

24 E-flite Leader 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 page 43) or
go to horizonhobby.com to find a local Spektrum
distributor in your country for service if using a
Spektrum radio system.

Flying Your Model

The Leader 480 is an extremely well mannered low­wing park flyer with the heart of a pattern plane.

Its ground handling characteristics are very forgiving
due to the tricycle landing gear arrangement. Set the
throttle trim such that the propeller is spinning over at
a very low RPM. Taxi out to the runway and line up
with the centerline and check to ensure that the controls
are moving in the correct directions and that your rate
switches are set to their proper positions. Smoothly
advance the throttle and hold slight back pressure on
the elevator. Use very small rudder corrections to keep
the airplane tracking straight down the runway, and
the Leader should gently break ground after a short
takeoff roll and settle into a moderate climb angle.
Once at altitude, set cruise power to between ½ to
¾ throttle and trim for straight and level flight. After
trimming and making a few passes, try some slow
flight. Point the nose into the wind and reduce power
and feed up elevator to maintain level flight. The
airplane will slow down to a crawl and break straight
ahead.

Now for the fun part. With the light weight of the
airframe, and the power of the Park 480 motor, the
Leader 480 is a very capable aerobatic performer.
Due to the force arrangement and the generous tail
moment, the Leader tracks incredible lines. Big loops,
slow axial rolls, snap rolls, inverted flight, spins, stall
turns, and more are well within this agile flyer’s realm
of capability. Use your imagination to create your own
aerobatic sequence for endless fun.

When the time comes bring this bird back to earth, fly
parallel to the runway downwind and slowly reduce
power. Begin to bleed off airspeed and descend. Once
lined up with the runway, use the elevator to control
airspeed and power to control rate of descent and
establish a stable glidepath to the approach end of the
runway. Once you are a few feet above the runway,
begin to shallow your descent rate and reduce power
completely. Once you settle into ground effect, it will
settle onto the runway in a slightly nose-high attitude.
If the nose is kept high during the roll out, speed will
bleed off much quicker. Just as with the takeoff, use
small rudder corrections to keep the airplane tracking
straight down the runway.

Congratulations, you have just flown your Leader 480!
We wish you many more happy flights with this model.
Now grab a battery and do it again!

Happy Landings!
