Introduction

Congratulations on buying the Shoestring 15e. You
have purchased what is arguably one of the most
fun airplanes in the marketplace today. Originally
designed as a fast sport flyer to bring an adrenaline
rush to mid- to advanced-level pilots, the project
quickly advanced to an even greater purpose. Working
with legendary designers Dan Kane and Jerry
Small, we developed the airplane into the standard
for the upcoming Electric Formula One racing class
from the NMPRA (National Miniature Pylon Racing
Association).

We have designed a unique cowl system that includes
all the graceful curves of the front of the fuselage into
one piece that stretches back to the mid canopy point.
This allows for very easy maintenance, easy mounting
of equipment, and great cooling for the EP power
system. We also elected to use mini servos throughout
to save weight and expense.

Power for your airplane can be anything from our
Power 15 motor on a 3S setup and 10 x 10E prop
(prop clearance limits anything longer) to a full blown
race setup with our new Power 25 1250Kv on 4S and
an 8 x 8E prop turning about 15,000 rpm. The sport
setup will put you in the 80 mph range while the race
setup has been clocked at about 115 mph.

The airplane is a smooth flyer and goes exactly
where you point it. Make sure all your friends pick up
one of these kits, then challenge each other to some
impromptu racing for bragging rights at your local
field. You’ll have a blast!

4 E-flite Shoestring 15e ARF Assembly Manual

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), take note that these are

in relationship to the pilot sitting in the cockpit

of the aircraft unless noted otherwise.

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.

Threadlock Flat blade screwdriver
Hobby scissors Hobby knife with #11 blade
Open-end wrench: 10mm
Hex wrench or ball driver: 2.5mm, 3mm

Always use threadlock on metal-to-metal fasteners

to prevent them from vibrating loose.

 1. Secure the landing gear to the bottom of the

aircraft using two 4mm x 15mm socket head bolts,
two 4mm washers and two 4mm lock washers. The
straight side of the gear faces to the front of the
aircraft. Use a 3mm hex wrench or ball driver to
tighten the bolts.

 2. Use hobby scissors and a hobby knife with

a #11 blade to trim the landing gear fairings.
Leave the size of the fairings slightly over-sized.

 3. Fit the landing gear fairings over the gear.

Slowly trim the fairings to fit to the fuselage. When
installed, they will cover the area where the landing
gear attaches to the fuselage. Use clear tape to
secure the fairings to the fuselage.

 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.

5E-flite Shoestring 15e ARF Assembly Manual

 4. Remove the hardware from the axle. Place a

drop of light machine oil on the axle to help the

Right wing panel with aileron

Required Tools and Adhesives

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

 1. Remove the aileron and hinges from the wing

panel. Use a pin vise and 1/16-inch (1.5mm) drill
bit to drill a hole in the center of each hinge slot.
Drill holes in both the aileron and wing. This creates
a tunnel for the CA to wick into, making a better
bond between the hinge and surrounding wood.

 3. Place the hinges in the aileron as shown.

 4. Slide the aileron back into position.

 5. Remove the T-pins, then press the aileron tightly

against the wing. Center the aileron in the opening
and check that it can move freely without binding
at the root or tip. Wick thin CA into the top and
bottom of all three hinges.

 6. Once the CA has fully cured. Gently pull on the

aileron to make sure the hinges are secure. If any
hinges are loose, reapply CA to the hinge. Flex the
aileron through its range of motion a number of
times to break in the aileron hinges.

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

hinges. This will center the hinges when installed in
the aileron.

When gluing the hinges, do not use CA

accelerator. The CA must be allowed to

soak into the hinge to provide the best bond

between the hinge and surrounding wood.

 7. Repeat Steps 1 through 7 to hinge the

remaining aileron.

drill the holes for the servo mounting screws.

 4. 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.

 5. Apply 2–3 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.

8 E-flite Shoestring 15e ARF Assembly Manual

 6. Secure the servo using the screws provided with

the servo and a #1 Phillips screwdriver. The output
shaft of the servo will align with the opening in the
cover. Center the aileron servo using the radio system.

 8. Fit the servo horn to the servo so it is

perpendicular to the servo. Use side cutters
to remove the arms that do not protrude
through the cover.

 10. Tie the string around the extension. Use the

string to pull the extension through the wing root.

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

to enlarge the hole in the servo arm 1/2 inch

and a #1 Phillips screwdriver.

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

drill the two holes completely through the aileron for
the aileron control horn mounting screws. The holes
have already been started and are easily found on
the bottom of the aileron

 14. Attach the control horn to the aileron using two

2mm x 12mm sheet metal screws and a control
horn backplate. Use a #1 Phillips screwdriver to
tighten the screws.

 15. With the aileron servo centered, attach the

Z-bend of the 2-inch (52mm) pushrod to the aileron
servo horn. Thread a clevis on the pushrod. Adjust
the clevis so when it is attached to the control horn
the aileron is centered. Tighten the 2mm nut against
the clevis using needle nose pliers to prevent the
clevis from vibrating loose.

the fuselage. Position the servo so the edge toward
the center is centered in the opening. Use a pencil
to transfer the positions for the mounting screws on
the servo tray.

17E-flite Shoestring 15e ARF Assembly Manual

 2. Remove the servo from the fuselage. Use a pin

vise and 1/16-inch (1.5mm) drill bit to drill the four
holes for the servo mounting screws.

 4. Place 2–3 drops of thin CA in each hole to

harden the surrounding wood. This harder surface
makes the screws more secure when installed.

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

to enlarge the hole in the servo arm 3/8 inch
(10mm) from the center of the servo horn. Remove
the arms from the servo horn that will not be used
using side cutters.

 3. 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. Prepare all four mounting
holes at this time.

 5. Return the servo to the fuselage. Use a #1 Phillips

screwdriver and the screws provided with the servo
to secure it in the fuselage.

 7. Insert the Z-bend from the pushrod wire through

the hole in the servo horn. Use the radio system to
center the rudder servo. Install the servo horn so
it is perpendicular to the servo center line. Secure
the horn using the screw from the servo and a #1
Phillips screwdriver.

18 E-flite Shoestring 15e ARF Assembly Manual

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

bit to drill the two locations for the control horn
mounting screws. The locations have been pre­drilled at the factory.

 9. Secure the control horn to the rudder using two

2mm x 12mm sheet metal screws and a control
horn backplate. Tighten the screws using a #1
Phillips screwdriver.

 10. Use a square or straight edge to make sure

the rudder is in alignment with the fin. The clevis
attaches to the outer hole on the control horn.
Adjust the clevis as necessary so the rudder is
aligned with the fin when the rudder servo is
centered. Once aligned, use needle nose pliers to
tighten the nut against the clevis to keep it from
vibrating loose.

 12. Use hook and loop tape to install the receiver in

the fuselage. Connect the rudder and elevator servo
to the receiver. Secure the remote receiver in the
fuselage using hook and loop tape.

 11. Repeat steps 3 through 10 to connect

the elevator pushrod wire. The positions and
measurements for the elevator connections are the
same as the rudder.

When flying in extreme High-G racing, it may

be a good idea to use a tie-wrap (not included)

to secure the position of the receiver.

holes should be drilled.

 2. Place the canopy back on the fuselage and

attach the wings. Slide the cowl on the fuselage.
You will need to flex the cowl to fit it over the
landing gear fairings on the bottom of the fuselage.

 4. Slide the propeller adapter and spinner

backplate on the motor shaft. Check that the cowl
is aligned with the spinner backplate. There should
also be a 5/64 inch (2mm) gap between the
backplate and cowl. Use two pieces of low-tack
tape to hold the cowl in position on the fuselage.

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.

 3. Prepare the spinner assembly by sliding the

propeller on the adapter shaft. Place the adapter
nut on the shaft, but do not tighten it at this time.

 6. Once aligned, use a pin vise and 1/32-inch

Required Tools and Adhesives

Felt-tipped pen Ruler
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 23/8 to 25/8 inches (60
to 66mm) 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.

24 E-flite Shoestring 15e ARF Assembly Manual

 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.

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 should make the airplane
elevator move up.

 3. Check the movement of the ailerons with the

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

Rudder

High Rate
Right: 11/16-inch 17mm
Left: 11/16-inch 17mm
Low Rate
Right: 19/32-inch 15mm
Left: 19/32-inch 15mm

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.

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.

 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:

Aileron

High Rate
Up: 3/8-inch 10mm
Down: 1/4-inch 6mm
Low Rate
Up: 5/16-inch 8mm
Down: 3/16-inch 5mm

Elevator

High Rate
Up: 9/32-inch 7mm
Down: 1/4-inch 6mm
Low Rate
Up: 3/16-inch 5mm
Down: 5/32-inch 4mm

Travel Adjust and Sub-Trims are not listed

and should be adjusted according to each

individual model and preference.

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.

25E-flite Shoestring 15e ARF Assembly Manual

Preflight

Range Test Your Radio

Flying Your Model

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, 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.

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. Ensure 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.

POWER 15 SPORT SETUP

If you followed the suggestions for the sport setup,
you’ll have adequate control throws to do just about
any aerobatic maneuver you want from an airplane
that is designed to fly fast. Balance the airplane at the
23/8 inches (60mm) mark to start with and then adjust
fore and aft from there by moving the motor battery.
The initial CG will provide a very solid feeling airplane
that will readily stall with full up elevator, which gives
good control for landings.

Take-off

Use care with a 10-inch propeller mounted, especially
off the grass. A smooth application of throttle will result
in a fairly straight takeoff run, needing a small amount
of right rudder. When the tailwheel is on the ground
(before the tail has risen) it provides good authority

against any torque-induced yaw.... Once the tailwheel

lifts off the ground, be prepared to apply additional
right rudder to keep the airplane on a straight path.
It takes about 8–10 seconds for the airplane to gain
full speed, but you don’t have to wait for this speed to
have fun. With the light wing loading, you’ll find the
Shoestring 15e to be very maneuverable and fun to fly.

POWER 25 1250KV RACING SETUP

This setup is an entirely different animal. This setup
will raise the top speed from around 80 mph to 115
mph and will provide you with many hours of pure
adrenaline (at 4 minutes or so per flight). The size of
the loops you can do will amaze you. Balance the
airplane at the 2
and then adjust fore and aft from there by moving
the motor battery. The initial CG will provide a very
solid feeling airplane that will readily stall with full
up (high-rate) elevator, which gives good control for
landings. We recommend following the suggestions on
the pushrod attachment in the manual for the racing
setup. Using the inner holes at the servo will result in
the greatest amount of torque being delivered to the
control surface. At these speeds, it is good to have a
reserve of holding power and extra torque.

Take-off

Landing

Daily Flight Checks

With the high Kv motor and a small 8-inch propeller,
there is a ton of torque coming from your motor, so
be prepared on your first takeoff. The airplane will
easily come off the ground at 1/2 throttle, so if you
stop yourself from going full bore and wait to apply
full power until well airborne, your takeoffs will be
easier and a thing of beauty. While the tailwheel is
on the ground it provides good authority against any
torque-induced yaw, but once the tailwheel lifts off, be
prepared to apply additional right rudder to keep the
airplane on a straight path. With an 8-inch pitch prop,
it takes a full 15 seconds for the airplane to gain full
speed.

Racing tips

The key to going fast and maintaining your speed is to
induce the least amount of drag while you are flying
the airplane. Every time you move a flight control you
increase the drag, so use very little control surface
movement to help with this. Get used to using a lot of
stick movement on your transmitter (on all axes) and
your ability to make smooth corrections and fly a faster
line through the air will increase tremendously.

I like to set up my transmitter so almost full elevator
stick movement is required to complete a turn around a
pylon. Ailerons are set up so a complete full roll takes
2–3 seconds (the distance from one end of a racing
course to the other). I usually also set up my rudder so
that full right rudder will provide a straight takeoff run
with a wide open throttle. I also mix in a little rudder
with aileron movement (about 4%); just enough so you
can roll from right knife edge to left knife edge and
back again without gaining any altitude.

Some tips on passing your racing friends. Stay above
their racing line. There is a tremendous amount of
what we call bad air (turbulence) right behind and
below them. While it might seem cool and exciting
to execute a pass below, at these speeds there is
rarely any time to correct from turbulence before your
beloved racer is in the ground. Take heed!

Landing your model is identical whether you are using
the Sport (Power 15) or Racing (Power 25) setups.
With the wing loading at about 21 ounces per square
foot, the landing speeds for this airplane are actually
very slow … if you can get it to slow down. It is a
very clean airplane and if you let the nose drop on
approach, it will pick up all the speed you just worked
so hard to lose. Just go to high rate to make sure you
have adequate elevator once you get the airplane
slowed down when it is least effective. Plan your
approach and be prepared to make a go-around on
the first few tries. You’ll get the hang of it very quickly.

Happy Landings!

 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. Ensure the control
surfaces and linkages are not binding and 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.
