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.

installing the rubber grommets and brass eyelets.
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.
