For the latest technical updates or manual corrections to the
Extra 300S visit the Great Planes web site at

www

.greatplanes.com

. Open the “Airplanes” link, then
select the Extra 300S 1.60 ARF . If there is new technical
information or changes to this model a “tech notice” box will
appear in the upper left corner of the page.

1. Your Extra 300S should not be considered a toy, but rather a
sophisticated, working model that functions very much like a full­size airplane.Because of its performance capabilities, the Extra
300S, if not assembled and operated correctly, could possibly
cause injury to yourself or spectators and damage to property.

2. You must assemble the model according to the
instructions.Do not alter or modify the model, as doing so may
result in an unsafe or unflyable model. In a few cases the
instructions may differ slightly from the photos.In those instances
the written instructions should be considered as correct.

3. You must take time to build straight, true and strong.

4. You must use an R/C radio system that is in first-class
condition, and a correctly sized engine and components
(fuel tank, wheels, etc.) throughout the building process.

5. You must correctly install all R/C and other components so
that the model operates correctly on the ground and in the air .

6. You must check the operation of the model before every
flight to insure that all equipment is operating and that the
model has remained structurally sound. Be sure to check
clevises or other connectors often and replace them if they
show any signs of wear or fatigue.

7. If you are not already an experienced R/C pilot, you
should fly the model only with the help of a competent,
experienced R/C pilot.

8. While this kit has been flight tested to exceed normal
use, if the plane will be used for extremely high stress
flying, the modeler is responsible for taking steps to
reinforce the high stress points.

9. WARNING: The cowl and wheel pants included in this kit
are made of fiberglass, the fibers of which may cause ey e, skin
and respiratory tract irritation. Never blow into a part (wheel
pant, cowl) to remove fiberglass dust, as the dust will blow
back into your eyes. Always wear safety goggles, a particle
mask and rubber gloves when grinding, drilling and sanding
fiberglass parts. Vacuum the parts and the work area
thoroughly after working with fiberglass parts.

Remember:Take your time and follow the instructions to
end up with a well-built model that is straight and true.

NOTE:W e, as the kit manuf acturer , pro vide you with a top quality

kit and great instructions, but ultimately the quality of your
finished model depends on how you build it;therefore, w e cannot
in any way guarantee the performance of your completed model,
and no representations are expressed or implied as to the
performance or safety of your completed model.

If you have not flown this type of model before, we
recommend that you get the assistance of an experienced
pilot in your R/C club for your first flights. If you’re not a
member of a club, your local hobby shop has information
about clubs in your area whose membership includes
experienced pilots.

In addition to joining an R/C club, we strongly recommend y ou
join the AMA (Academy of Model Aeronautics). AMA
membership is required to fly at AMA sanctioned clubs.There
are over 2,500 AMA chartered clubs across the country.
Among other benefits, the AMA provides insurance to its
members who fly at sanctioned sites and events. Additionally,

When you see the term

test fit

in the instructions, it
means that you should first position the part on the
assembly without using any glue, then slightly modify
or

custom fit

the part as necessar y for the best fit.

·

Whenever the term

glue

is written you should rely upon
your experience to decide what type of glue to use.When
a specific type of adhesive works best for that step, the
instructions will make a recommendation.

·

Whenever just

epoxy

is specified you may use

either

30­minute (or 45-minute) epoxy or6-minute epoxy. When
30-minute epoxy is specified it is highly recommended
that you use only 30-minute (or 45-minute) epoxy,
because you will need the working time and/or the
additional strength.

Photos and sketches are placed before the step they
refer to. Frequently you can study photos in following

Important Building Notes

Ordering Replacement Parts

❏ 1. If you have not done so already, remove the major

parts of the kit from the box and inspect for damage. If any
parts are damaged or missing, contact Product Suppor t at
the address or telephone number listed in the “Kit
Inspection” section on page 4.

❏ 2. Remove the tape and separate the ailerons and flaps

from the wing and the elevators from the stab. Use a
covering iron with a covering sock on high heat to tighten
the covering if necessary. Apply pressure over sheeted
areas to thoroughly bond the covering to the wood.

Do the right wing first so your work matches the
photos the first time through.You can do one wing at a
time, or work on them together.

❏❏1. Drill a 3/32" [2.4mm] hole, 1/2" [13mm] deep in the

center of each hinge slot to allow the CA to “wick”in.Follow­up with a #11 blade to clean out the slots.
Hint: If you have one, use a high-speed rotary tool to drill
the holes.

❏❏2.Use a sharp #11 blade to cut a strip of covering from

the hinge slots in the wing and aileron.

❏❏3. Cut five 3/4" x 1" [19 x 25mm] hinges from the CA

hinge strip. Snip off the corners so they go in easier.

❏❏4. Test fit the ailerons to the wing with the hinges. If

the hinges don’t remain centered, stick a pin through the
middle of the hinge to hold it in position.

❏❏5. Remove any pins you may have inserted into the

hinges. Adjust the aileron so there is a small gap between the
LE of the aileron and the wing. The gap should be small, just
enough to see light through or to slip a piece of paper through.

❏❏6. Apply six drops of thin CA to the top and bottom of

each hinge. Do not use CA accelerator. After the CA has
fully hardened, test the hinges by pulling on the aileron.

Install the Ailerons

ASSEMBLE THE WING

PREPARATIONS

6

❏❏7. Cut the covering 1/8" [3mm] inside the opening in

the wing for the aileron servo. Use a trim iron to seal the
covering to the inner edges of the opening.

❏❏8. On the top of the wing, cut the covering away from

the hole at the wing center section. This hole is for the
aileron servo wire to come through, into the fuselage.

❏❏9. On the top and bottom of the wing, cut the covering

away from the hole near the wing trailing edge.This hole is
for the wing bolt.

❏❏10. Remove the string from inside of the aileron servo

bay and tape it to the wing. Do not pull the string out of
the wing!

❏ 11. Repeat steps 1-10 for the left wing panel.

❏❏1. Installing the servos in the wing will require the use

of one 12" [305mm] servo extension for each aileron servo.
One Y-harness connector is required and is used to allow
the aileron servos to plug into one slot in your receiver.You
may have a computer radio that allows you to plug the
servos into separate slots and then mix them together
through the radio transmitter .If you choose to mix them with
the radio rather than the Y-harness, refer to the instructions
with your particular brand of radio.

❏❏2. Attach the servo extension to the aileron servo.

Secure the connectors together using a large piece of heat
shrink tubing, tape or other method for securing the
connectors together.

❏❏3.Tie the string from inside the wing to the end of the

servo wire. Pull the servo wire through the wing with the
string.Feed the servo wire out the hole in the top of the wing
center section.Tape the servo wire to the wing to prevent it
from falling back into the wing.

❏❏4.Temporarily position the aileron servo into the servo

bay. Drill a 1/16" [1.6mm] hole through the four mounting
holes of the servo, drilling through the plywood mounting
plate in the wing. Install and remove a servo mounting
screw into each of the four holes. Insert a drop of thin CA
into the holes to harden the wood.After the glue has cured,
install the servo into the servo bay using the hardware that
came with your servo. Center the servo and install a servo
arm as shown.

Install the Aileron servos & pushrods

7

❏❏5. The aileron has a plywood plate for mounting the

control horn. Using a T-pin, lightly puncture the covering to
be sure you are over the plywood plate. Position a large
nylon control horn on the aileron, positioning it as shown
in the sketch and aligning it with the servo.Mark the location
for the screw holes.Dr ill through the marks you made with
a 3/32" [2.4mm] drill bit. (Be sure you are drilling into the
plywood plate mounted in the bottom of the aileron. Drill
through the plate only. Do not drill all the way through the
aileron!) Using a #4 x 5/8" 16mm] sheet metal screw, install
and then remove a screw into each of the holes .Harden the
holes with thin CA.Install the control horn with four #4 x 5/8"
[16mm] sheet metal screws.

❏❏6.Locate a .095" x 12" [.095" x 305mm] pushrod wire

threaded on one end. Screw a 4-40 nut, a silicone clevis
keeper and a threaded metal clevis onto the threaded end
of the wire 20 turns. Tighten the nut against the clevis and
then install the clevis on the aileron control horn.

❏❏7. Be sure the aileron ser vo is centered. Enlarge the

outer most hole in the servo arm with a Hobbico Servo Horn
Drill (or a #48 or 5/64" [2mm] drill bit). Install a 4-40 metal
solder clevis onto the outer most hole in the servo arm.
Center the servo arm and center the aileron. Using the

solder clevis as a guide, mark where to cut the pushrod
wire. Remove the pushrod and clevis from the control horn
and the solder clevis from the servo arm. Solder the clevis
to the pushrod using the “Expert Tip” that follows.

❏❏8. Install a silicone clevis retainer over the solder clevis.

Install the pushrod and clevises to the servo arm and the
control horn. Adjust the linkage until the aileron and the servo
arm are both centered then tighten the nut against the clevis.

❏ 9. Repeat steps 1-8 for the left wing panel

HOW TO SOLDER THE CLEVIS

TO THE PUSHROD

1. Where the pushrod will make contact with the solder
clevis, roughen the wire with 220-grit sandpaper.

2. Use denatured alcohol to remove any oil residue from
the pushrod wire.

Note: Soldering should be done with silver solder not an
electrical solder. Great Planes®has a convenient Silver
solder kit (GPMR8070) that includes flux and solder.

3. Apply a couple of drop of flux to the wire. Slide the
solder clevis onto the wire. Using a small torch or
soldering iron heat the wire, allowing the heated wire
to heat the solder clevis. Apply a small amount of
solder to the joint.When the wire and the clevis are hot
enough the solder will flow into the joint. Avoid using
too much solder causing solder to flow out of the joint
and clump. Use just enough solder to make a good
joint. Allow the wire and clevis to cool.

4. Put a couple of drops of oil onto a rag and wipe the
joint.This will prevent rust from forming on the joint.

❏ 1. Locate three nylon anti-rotation pins.Using 6-minute

epoxy, glue one into the root on one wing half and one into
each of the holes in the wing’s center section. The pin
should extend approximately 1/2" [13mm]. Clean any
excess epoxy away from the pins with rubbing alcohol
before the epoxy cures.

❏ 2. Using 6-minute epoxy, glue the remaining anti-rotation

pin into the hole in the leading edge of the belly pan.The pin
should extend approximately 1/2" [13mm] from the belly
pan. Clean any excess epoxy away from the pins with
rubbing alcohol before the epoxy cures.

❏ 3. At the rear of the wing saddle you will find a hole. Cut

the covering away from this hole.

❏ 4. Slide the two wing halves together onto the aluminum

joiner tube.Install the wing onto the fuselage with two nylon
wing bolts.

❏5.Cut the covering away from the hole at the bottom rear

of the belly pan.

❏ 6. Insert the pin on the leading edge of the belly pan into

the hole in the former. Push the belly pan onto the wing.
Hold the belly pan in place with a 6-32 x 5/8" [16mm] socket
head cap screw.
Note:The screw threads into a blind nut in the fuselage.Be
sure the threads grab the blind nut before pushing too hard
and dislodging the blind nut.

❏ 7. Remove the wing and belly pan from the fuselage.
