Introduction
Using the Manual
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.
This manual is divided into sections to help make
assembly easier to understand, and to provide breaks
between each major section. In addition, check boxes
have been placed next to each step to keep track
of its completion. Steps with a single circle () are
performed once, while steps with two or more circles
() indicate the step will require repeating, such as
for a right or left wing panel, two servos, etc.
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.
Remember to take your time and follow the directions.

Before Starting Assembly
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.

 9. Insert the control horn in the slit in the rudder
(or elevator).
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.
 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.
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.

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.
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.

Balancing stand (optional)

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.
An important part of preparing the aircraft for flight is
properly balancing the model.

5. Use a hobby knife and #11 blade to remove
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.
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.
Balancing Stand
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.
After the first flights, the CG position can be adjusted
for your personal preference.

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.

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)

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.

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.
E-flite Leader 480 ARF Assembly Manual
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.
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!
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.
