1. Locate the wing panel. Separate the aileron from
the wing panel. Set the four hinges aside at this time.
2. 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
wing panel. This will provide a tunnel for the CA to
wick into, making the bond between the hinge and
wood stronger.
4 E-flite Advance 25e ARF Assembly Manual
3. Prepare the aileron for hinging following the
procedure described in Step 2.
5. Slide the hinges in the aileron into the slots on
the wing. Check that the gap at each end of the
aileron is equal.
7. Once the CA has fully cured, gently pull on the
wing and aileron to make sure the hinges are glued
securely. If not, reapply thin CA to any hinges that
are not secure.
4. Slide the hinges into the aileron. Insert the
hinges so the holes in the hinge are at the hinge
line. Insert a T-pin through one of the holes to keep
the hinge centered when the aileron is installed on
the wing panel.
When gluing the hinges, do not use a CA
accelerator. The CA must be allowed time to
soak into the hinges to provide the best bond
between the hinge and surrounding wood.
6. Remove the T-pins from the hinges. Make sure
the aileron is tight against the wing. Wick thin CA
into each hinge, both top and bottom, until the
hinge is saturated with CA. Allow the CA to fully
cure before proceeding.
8. Flex the aileron through its range of motion
a number of times to break in the hinges. This
will reduce the initial load on the servo for your
first flights.
9. Repeat Steps 1 through 8 to install the remaining
aileron and hinges.

1. Prepare the aileron servo by installing the rubber
grommets and brass eyelets as described in the
servo instructions.
2. Use a #1 Phillips screwdriver to thread a
servo mounting screw in each of the four servo
mounting holes. This will cut threads into the
surrounding wood.
3. Apply 2–3 drops of thin CA in each of the servo
mounting holes. This will harden the threads in
the surrounding wood, which will help prevent the
screws from vibrating loose.
4. Carefully remove the string from the servo
pocket. Make sure not to pull the string loose from
the center of the wing. Tie the end of the string
around the servo lead near the connector.
Before starting the installation of the servos, it is
recommended to center the trims and sticks on your
transmitter. If you are 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.

the wing and out of the hole in the top of the
wing panel.
7. Use the radio system to center the aileron servo.
Position the servo horn parallel to the hinge line
of the aileron. Enlarge the hole in the servo horn
facing toward the wing tip that is 1/2-inch (13mm)
from the center of the horn using a pin vise and
5/64-inch drill bit. Use side cutters to remove any
unused arms from the servo horn so they don’t
interfere with the operation of the aileron servo.
8. Position a square so it is aligned with the edge of
the wing and the hole in the servo horn enlarged in
Step 6. Use a felt-tipped pen to mark the aileron for
the aileron control horn. This aligns the horn and
linkage correctly for your model.
Leave a small amount of string tied to the servo lead.
Tape the string to the top of the wing to prevent
the servo lead from falling back into the wing.
6. Use the screws provided with the servo to secure
it in the wing. The output shaft of the servo will face
the aileron. Use a #1 Phillips screwdriver to tighten
the servo mounting screws.
9. Position the control horn on the aileron. The holes
in the control horn will align with the hinge line of
the aileron, and with the mark made in the previous
step. Use a felt-tipped pen to transfer the locations
for the control horn mounting screws on the aileron.
When installing the aileron servos, the
linkages must connect to the side of the
servo facing the wing tips as shown.
7E-flite Advance 25e ARF Assembly Manual
10. Use a pin vise and 5/64-inch (2mm) drill
bit to drill the two holes for the control horn
mounting screws.
11. Apply 2–3 drops on thin CA in each of the
holes to harden the surrounding wood. This will keep
the control horn secure and prevent the surrounding
wood from becoming damaged over time.
12. Attach the control horn to the aileron using two
2mm x 12mm machine screws and the control horn
backplate. Use a #1 Phillips screwdriver to tighten
the screws. Make sure not to over-tighten the screws
and damage the underlying wood.
14. Slide the small piece of tubing in a nylon clevis.
Thread the clevis 12-turns on a 117/8-inch (302mm)
threaded pushrod wire. This will provide enough
threads in the clevis to be secure and allow for
adjustment of the linkage.
15. Wrap a small piece of low-tack tape around
the aileron and trailing edge to keep the aileron
centered. Attach the clevis to the outer hole of the
control horn.
13. Use a hobby knife with a #11 blade to cut a
1/4-inch (6mm) piece from the silicone tube.

16. Use a felt-tipped pen to mark the pushrod
where it crosses the hole in the servo horn that was
enlarged in Step 6.
Making a Z-bend takes some skill. There is
plenty of excess wire to experiment with. We
recommend using Z-bend pliers (HAN119) to
make the perfect Z-bend in your pushrod wire.
1. Locate the hardwood wing joiner. Mark the joiner
and wing panels with an “R” and “L” so the joiner
can be associated with a particular wing panel for
test fitting.
18. Insert the bend in the hole of the servo
horn. Reconnect the clevis to the outer hole of
the control horn. Slide the silicone tube over
the forks of the clevis to prevent it from opening
accidentally in flight.
2. Slide the wing joiner into one of the wing panels.
Use a pencil to draw a line on the joiner against the
wing as shown. The joiner should easily slide into
the wing panel. If not, use medium grit sandpaper
to lightly sand the joiner so it slides in easily.
19. Repeat Steps 1 through 19 to install the
remaining aileron servo and linkage. Remove the
low-tack tape securing the aileron before joining the
wing panels.
9E-flite Advance 25e ARF Assembly Manual
3. Slide the joiner into the opposite wing panel.
It should slide in up to or past the line drawn in
the previous step. If not, you will need to sand the
joiner using medium grit sandpaper so it fits.
4. Slide the two wing panels together. They should
fit together tightly with no gaps. If there are
gaps, use medium grit sandpaper to make any
necessary adjustments.
5. Separate the wing panels and remove the joiner.
Mix 1/2 ounce (15mL) of 30-minute epoxy. Use a
mixing stick to apply epoxy into the joiner pocket of
one of the wing panels.
Before applying epoxy, wrap low-tack tape 1/32inch (1mm) from the root edge of the wing to help
prevent the epoxy from running onto the wing.
7. Use an epoxy brush to apply the epoxy to one
half of the joiner. Make sure to coat the front, back,
top and bottom of the joiner with epoxy.
8. Slide the wing joiner into the wing panel. Use
a paper towel and rubbing alcohol to remove any
excess epoxy.
6. Use an epoxy brush to apply a thin coat of epoxy
to the exposed wood on the wing root as shown.
The following steps must be completed
before the epoxy begins to cure. Make
sure to read through and understand the
following steps before mixing any epoxy.
10 E-flite Advance 25e ARF Assembly Manual
9. Repeat Steps 5 through 8 to apply epoxy to the
exposed joiner and to the remaining wing panel.
Slide the panels together and use low-tack tape to
hold them tightly together until the epoxy fully cures.
Make sure to use a paper towel and rubbing alcohol
to remove any excess epoxy before it begins to cure.
10. Once the epoxy has fully cured, remove the
tape from the wing.

3. Use the radio system to center the rudder servo.
Enlarge the hole in the servo arm that is 1/2-inch
(13mm) from the center of the servo for the rudder
pushrod. Use side cutters to remove the shorter
arms from the horn so they don’t interfere with the
operation of the servo. Make sure to leave the two
arms as shown: one connects to the rudder, the
other connects to the nose gear steering. Do not
enlarge any of the holes on the side of the arm for
the steering pushrod.
We recommend working through the next two sections
of the manual to allow the epoxy to fully cure.
4. Use a #1 Phillips screwdriver to thread a
servo mounting screw in each of the eight servo
mounting holes. This will cut threads into the
surrounding wood.
2. Use the radio system to center the elevator
servo. Enlarge the hole in the servo arm that is
1/2-inch (13mm) from the center of the servo. Use
side cutters to remove the remaining arms from
the horn so they don’t interfere with the operation
of the servo.
11E-flite Advance 25e ARF Assembly Manual

1. Use medium grit sandpaper to lightly sand a
1/4-inch (6mm) wide section of the 117/8-inch
(302mm) pushrod tube. This provides a surface for
the CA to bond to when the pushrod is glued in the
fuselage. Use the photo to locate the areas that are
21/4-inch (57mm) and 6-inches (147mm) from the
end of the tube.
2. Remove the battery cover by rotating the knob on
the cover 90-degrees. Lift the cover and set it aside
in a safe location.
3. Slide the pushrod tube into the fuselage
through the oval hole in the firewall with the
21/4-inch (57mm) sanded end first. The tube
will be routed up through the battery tray, then
through the hole in the former near the servo
tray. With the end of the tube flush with the
firewall, use medium CA to glue the tube where
it crosses the formers inside the fuselage.
Always use threadlock on metal-to-metal fasteners.
4. Attach the nose gear mount to the firewall using
four 3mm x 15mm machine screws and a #1

Always use threadlock on metal-to-metal fasteners.
5. Position the steering arm in the nose gear mount.
Slide the nose gear wire through the mount and
steering arm so it is flush with the top of the nose
gear mount. The steering arm will angle away from
the firewall so the nose wheel can operate properly.
Use a #1 Phillips screwdriver to tighten the screw in
the steering arm so it rests on the flat area on the
nose gear wire.
9. Use pliers to make a 90-degree bend in the wire.
Use side cutters to trim the wire 3/8-inch (9mm)
past the bend as shown.
Use the rudder trim on the radio to trim the
model in flight. If the model does not track
straight on the runway, adjust the clevis on
the steering linkage. Do not use the rudder
trim to correct the steering on your model.
7. Slide the steering pushrod wire into the tube from
the inside of the fuselage. Connect the clevis to the
outer hole of the rudder servo horn.
10. Insert the wire through the outer hole in the
steering arm. You may have to disassemble the nose
gear assembly to fit the wire through the hole.
8. Center the nose gear wire. The axle (where the

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.
9. Use the propeller adapter to secure the
propeller to the motor. Slide a 2.5mm-inch hex
wrench through the hole in the adapter to tighten
it, securing the propeller.
7. Use the hook and loop straps to secure the
battery to the battery tray.
8. 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.
We recommend using the optional spinner
to enhance the looks of your model.

4mm x 25mm machine screws
Plywood wing bolt plate
Required Tools and Adhesives
Felt-tipped pen Hobby knife with #11 blade
Medium CA Phillips screwdriver: #2
Paper towel Rubbing alcohol
Before installing the wing bolt plate, draw a centerline
on the underside of the plate and lightly score the
plate so it can easily conform to the dihedral angle
of the wing. Use care not to cut through the plate.
1. Place the plywood wing bolt plate on the bottom
of the wing. Trace the outline of the wing bolt plate
on the bottom of the wing. We used the two 4mm
x 25mm machine screws to keep the plate in the
correct position.
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.
2. Remove the plate from the wing. 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.
4. Connect the leads between the aileron Y-harness
and aileron servos.
5. Place the wing on the fuselage. Make sure
the aileron servo leads are tucked in and not
exposed between the wing and fuselage. Use two
4mm x 25mm machine screws and a #2 Phillips
screwdriver to secure the wing to the fuselage.
3. Use medium CA to glue the wing bolt plate to the
bottom of the wing. Make sure the holes are aligned
before the CA fully cures.

reference line down the center of the stabilizer
saddle.
3. Use a hobby knife and a #11 blade to remove
the covering from the center slot of the stabilizer.
4. Place the stabilizer on the fuselage. Use the
line drawn on the stabilizer saddle in Step 1 to
help align the slot in the stabilizer on the stabilizer
saddle. With the stabilizer as far forward on the
saddle as possible, use two T-pins to keep the
stabilizer in position to check its alignment.
5. Measure the distance from each stabilizer tip to
the fuselage centerline to make sure the stabilizer
is centered on the fuselage (A=A). Measure the
distance from each stabilizer tip to its respective
wing tip (B=B). These measurements must match
as close as possible. Adjust the position of the
stabilizer if necessary to position the stabilizer.
2. Separate the elevator and stabilizer. Leave the six
hinges in the elevator so they don’t get lost. Set the
elevator aside in a safe location to be installed later.
6. 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.
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.
21E-flite Advance 25e ARF Assembly Manual
7. 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.
The following steps must be completed
before the epoxy begins to cure. Make
sure to read through and understand the
following steps before mixing any epoxy.
9. Mix 1/2 ounce (15mL) of 30-minute epoxy.
Apply a thin coat of epoxy on the stabilizer saddle
with an epoxy brush.
11. Place the stabilizer back on the fuselage.
Recheck the alignment, then use T-pins to hold
the stabilizer in position. Use a paper towel and
rubbing alcohol to remove any excess epoxy before
it cures. Set the fuselage aside until the epoxy fully
cures.
Use care not to get epoxy in the slot at the
center of the stabilizer. This will change the fit
of the fin in the slot when it is installed.
12. Once the epoxy has fully cured, use a #2
Phillips screwdriver to remove the wing from the
fuselage. Set the wing aside in a safe location until
instructed to install it again.
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.
8. 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 1/16inch (1.5mm). Remove the covering, exposing the
bare wood. The lines can be removed using a
paper towel and rubbing alcohol.
13. Separate the rudder from the fin. Leave the
three hinges in the rudder so they don’t get lost.
Set the rudder aside in a safe location to be
installed later.
10. Use an epoxy brush to apply a thin coat of
epoxy to the exposed wood on the stabilizer.
22 E-flite Advance 25e ARF Assembly Manual
14. Remove the T-pins from the stabilizer. Position
the fin in the slot in the stabilizer. It must rest tightly
against the stabilizer. Use a felt-tipped pen to
transfer the top edge of the stabilizer on the bottom
of the fin.
15. Use a felt-tipped pen to trace the outline of the
fin on the top of the stabilizer.
16. Use a hobby knife and #11 blade to remove
the covering from the fin 1/16-inch (1.5mm) below
the line drawn in the previous steps.
17. Use a hobby knife and #11 blade to trim the
covering inside the lines drawn on the stabilizer by
1/16-inch (1.5mm). Remove the covering, exposing
the bare wood. The lines can be removed using a

19. Apply a thin coat of epoxy to the exposed
wood at the bottom of the fin.
20. Place the fin in position in the slot. Use
a square to make sure the fin is perpendicular
to the stabilizer.
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.
The following steps must be completed
before the epoxy begins to cure. Make
sure to read through and understand the

Hinging the Elevator and Rudder
Required Parts
Fuselage assembly Rudder with hinges
Elevator with hinges
Required Tools and Adhesives
Pin vise Drill bit: 1/16-inch
Thin CA T-pins
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
stabilizer. This will provide a tunnel for the CA to
wick into, making the bond between the hinge and
wood stronger.
3. Slide the hinges into the elevator. Insert the
hinges so the holes in the hinge are at the hinge
line. Insert a T-pin through one of the holes to keep
the hinge centered when the elevator is installed on
the stabilizer.
4. Slide the six hinges in the elevator into the slots
on the stabilizer. Check that the ends of the elevator
are aligned with the ends of the stabilizer.
When gluing the hinges, do not use a CA
accelerator. The CA must be allowed time to
soak into the hinges to provide the best bond
between the hinge and surrounding wood.
5. Remove the T-pins from the hinges. Make sure
the elevator is tight against the stabilizer. Wick thin
CA into each hinge, both top and bottom, until the
hinge is saturated with CA. Allow the CA to fully
cure before proceeding.
6. Once the CA has fully cured, gently pull on the
elevator and stabilizer to make sure the hinges are
2. Remove the hinges from the elevator. Prepare
the elevator for hinging following the procedure
described in Step 1.

pushrod wire will help aligning the horn. Use a
felt-tipped pen to mark the locations for the control
horn screws.
5. Use a pin vise and 5/64-inch (2mm) drill bit
to drill the two holes for the elevator control horn
mounting screws.
6. Apply 2–3 drops on thin CA in each of the holes
to harden the surrounding wood. This will keep the
control horn secure and prevent the surrounding
wood from becoming damaged over time.
7. Attach the control horn to the elevator using two
2mm x 12mm machine screws and the control horn
backplate. Use a #1 Phillips screwdriver to tighten
the screws. Make sure not to over-tighten the screws
and damage the underlying wood.
8. Use a ruler to check that the elevator and
stabilizer are in alignment with one another.
9. Use the radio system to center the elevator servo.
Use a felt-tipped pen to mark the pushrod where it
crosses the hole in the elevator servo horn that was
enlarged previously.
Making a Z-bend takes some skill. There is
plenty of excess wire to experiment with. We
recommend using Z-bend pliers (HAN119) to
make the perfect Z-bend in your pushrod wire.
26 E-flite Advance 25e ARF Assembly Manual
10. Make a Z-bend in the pushrod wire using a
pair of pliers. It may be necessary to disconnect the
clevis from the control horn to make the bend in the
pushrod wire.
11. Remove the servo horn from the servo. Insert
the bend in the hole of the servo horn. Secure the
control horn back on the servo using a #1 Phillips
screwdriver. Reconnect the clevis to the outer hole
of the control horn. Slide the silicone tube over
the forks of the clevis to prevent it from opening
accidentally in flight. Use side cutters to remove
any excess pushrod that might interfere with the
operation of the radio system.

Center of Gravity
Balancing Stand
Required Parts
Assembled airframe
Required Tools and Adhesives
Felt-tipped pen Ruler
Phillips screwdriver: #2
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.
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.
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 3 to 31/2 inches (76 to
89mm) 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.
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.
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%) (20% Exponential)
Up 19/32-inch (15mm) 23 degrees
Down 23/32-inch (18mm) 25 degrees

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.
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.
Flying Your Advance 25e ARF
The Advance 25e is a very spirited flyer yet is gentle
and forgiving during takeoff and landing.
Ground handling is easy due to the tricycle landing
gear. When on the runway, set the throttle trim to so
the motor is spinning low RPM. Then smoothly apply
power and apply a small amount of up elevator during
your takeoff roll. Make small corrections with the
rudder to keep the airplane tracking straight down the
runway. The Advance will lift off of the ground gently
and smoothly and settle into a gentle climb angle.
Once at altitude, trim the airplane at a cruise power
setting of ½ to ¾ throttle. After trimming and making a
few passes, try some slow speed flight at altitude. The
airplane is very stable at low airspeeds and during a
stall; it will break very gently straight ahead.
The Advance is easily capable of aerobatics such
as loops, rolls, spins, inverted flight and even knife
edge. Combine these to create an endless amount of
aerobatic maneuvers.
When setting up to land, reduce power and begin to
bleed off airspeed. Fly a traffic pattern and continue to
lose altitude. Line up to the runway on final approach
and allow the Advance to continue to descend. When
a few feet above the runway, begin to flare with up
elevator. Once the airplane settles into ground effect, it
will set down gently at a slightly nose-high attitude. If
the nose is kept high on roll out, the airplane will bleed
off speed much quicker. Use small corrections to keep
the airplane tracking straight down the runway.
Congratulations, you have just successfully flown
your Advance 25e! We hope you have many more
enjoyable flights with this model.
Happy Landings!

Daily Flight Checks
Warranty and Repair Policy
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.
1. Check the battery voltage of the transmitter
battery. Do not fly below the manufacturer’s
recommended voltage. To do so can crash
your aircraft.
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
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 at this time.

2010 Official Academy of Model
Aeronautics Safety Code
GENERAL
1. A model aircraft shall be defined as a non-humancarrying device capable of sustained flight in
the atmosphere. It shall not exceed limitations
established in this code and is intended to be used
exclusively for recreational or competition activity.
2. The maximum takeoff weight of a model aircraft,
including fuel, is 55 pounds, except for those flown
under the AMA Experimental Aircraft Rules.
3. I will abide by this Safety Code and all rules
established for the flying site I use. I will not
willfully fly my model aircraft in a reckless and/or
dangerous manner.
4. I will not fly my model aircraft in sanctioned events,
air shows, or model demonstrations until it has been
proven airworthy.
5. I will not fly my model aircraft higher than
approximately 400 feet above ground level, when
within three (3) miles of an airport without notifying
the airport operator. I will yield the right-of-way and
avoid flying in the proximity of full-scale aircraft,
utilizing a spotter when appropriate.
6. I will not fly my model aircraft unless it is
identified with my name and address, or AMA
number, inside or affixed to the outside of the
model aircraft. This does not apply to model
aircraft flown indoors.
7. I will not operate model aircraft with metal-blade
propellers or with gaseous boosts (other than
air), nor will I operate model aircraft with fuels
containing tetranitromethane or hydrazine.
8. I will not operate model aircraft carrying
pyrotechnic devices which explode burn, or
propel a projectile of any kind. Exceptions
include Free Flight fuses or devices that burn
producing smoke and are securely attached to
the model aircraft during flight. Rocket motors
up to a G-series size may be used, provided
they remain firmly attached to the model aircraft
during flight. Model rockets may be flown in
accordance with the National Model Rocketry
Safety Code; however, they may not be launched
from model aircraft. Officially designated AMA
Air Show Teams (AST) are authorized to use
devices and practices as defined within the Air
Show Advisory Committee Document.
9. I will not operate my model aircraft while under
the influence of alcohol or within eight (8) hours of
having consumed alcohol.
10. I will not operate my model aircraft while using
any drug which could adversely affect my ability to
safely control my model aircraft.
11. Children under six (6) years old are only allowed
on a flightline or in a flight area as a pilot or while
under flight instruction.
12. When and where required by rule, helmets must be
properly worn and fastened. They must be OSHA,
DOT, ANSI, SNELL or NOCSAE approved or
comply with comparable standards.
RADIO CONTROL
1. All model flying shall be conducted in a manner to
avoid over flight of unprotected people.
2. I will have completed a successful radio equipment
ground-range check before the first flight of a new
or repaired model aircraft.
34 E-flite Advance 25e ARF Assembly Manual
3. I will not fly my model aircraft in the presence of
spectators until I become a proficient flier, unless I
am assisted by an experienced pilot.
8. Under no circumstances may a pilot or other person
touch a model aircraft in flight while it is still under
power, except to divert it from striking an individual.
4. At all flying sites a line must be established, in front
of which all flying takes place. Only personnel
associated with flying the model aircraft are allowed
at or in front of the line. In the case of airshows
demonstrations straight line must be established.
An area away from the line must be maintained
for spectators. Intentional flying behind the line is
prohibited.
5. I will operate my model aircraft using only
radio-control frequencies currently allowed by
the Federal Communications Commission (FCC).
Only individuals properly licensed by the FCC
are authorized to operate equipment on Amateur
Band frequencies.
6. I will not knowingly operate my model aircraft
within three (3) miles of any preexisting flying
site without a frequency-management agreement.
A frequency management agreement may be
an allocation of frequencies for each site, a
day-use agreement between sites, or testing
which determines that no interference exists. A
frequency-management agreement may exist
between two or more AMA chartered clubs, AMA
clubs and individual AMA members, or individual
AMA members. Frequency-management
agreements, including an interference test report if
the agreement indicates no interference exists, will
be signed by all parties and copies provided to
AMA Headquarters.
9. Radio-controlled night flying is limited to lowperformance model aircraft (less than 100 mph).
The model aircraft must be equipped with a lighting
system which clearly defines the aircraft’s attitude
and direction at all times.
10. The operator of a radio-controlled model aircraft
shall control it during the entire flight, maintaining
visual contact without enhancement other than by
corrective lenses that are prescribed for the pilot.
No model aircraft shall be equipped with devices
which allow it to be flown to a selected location
which is beyond the visual range of the pilot.
Advance 25e
Safe Operating Recommendations
- Inspect your model before every flight to make
certain it is airworthy.
- Be aware of any other radio frequency user who
may present an interference problem.
- Always be courteous and respectful of other
users of your selected flight area.
- Choose an area clear of obstacles and large
enough to safely accommodate your flying
activity.
- Make certain this area is clear of friends and
spectators prior to launching your aircraft.
- Be aware of other activities in the vicinity of your
flight path that could cause potential conflict.
- Carefully plan your flight path prior to launch.
7. With the exception of events flown under official
AMA rules, no powered model may be flown
outdoors closer than 25 feet to any individual,
except for the pilot and located at the flightline.
- Abide by any and all established AMA National
Model Aircraft Safety Code.
