Introduction
The Extra 260 3D Profile was designed by Aerodynamicist
and E-TOC champ George Hicks to give profile 3D foamie
fans a great-looking, lightweight plane with competition-
level performance. At the heart of its superb flight
characteristics is a rigid, carbon reinforced Depron foam
airframe. This unique design eliminates flex so control
response is crisp and precise.
The Extra 260 is constructed from 3mm laser-cut Depron
foam—the standard for durability and quality for pro 3D
foamie pilots everywhere. All pieces come with a sharp-
looking factory-applied color scheme.
Carbon Rod Reinforcement
Much of the Extra 260’s exceptional flight performance
comes from its carbon-reinforced airframe that eliminates
flex so control response is crisp and precise. The leading
and trailing edges of the wing come out of the box with
factory-applied carbon strips. Carbon rods are also
included that further strengthen the fuselage and tail.

Using the Manual
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 each step completed.
Steps with a single circle () are performed once, while
steps with two circles () indicate that the step will
require repeating, such as for a right or left wing panel,
two servos, etc.
Remember to take your time and follow the directions.

You will need a minimum 6-channel transmitter (for proper
mixing and dual rate capabilities), crystals, micro receiver,
and three sub-micro servos. You can choose to purchase
a complete radio system that includes all of these items
or, if you are using an existing transmitter, just purchase
the other required equipment separately. We recommend
the crystal-free, interference-free Spektrum®DX6 2.4GHz
DSM®6-channel system, which includes a micro receiver
and 4 sub-micro 7.5 gram servos. If using your own
transmitter, we recommend the use of a JR SPORT™
6-channel UltraLite receiver and E-flite®S60 Super
Sub-Micro servos.

1. Locate the vertical and horizontal fuselage
pieces. Slide the horizontal fuselage into the
vertical fuselage starting at the opening for
the wing/radio equipment. Use care not to
damage any of the alignment tabs on the vertical
fuselage.

2. Locate the wing and slide it into the vertical
fuselage underneath the horizontal fuselage.
Use care not to damage either the vertical or
horizontal fuselage pieces.
Hint: Fold one of the ailerons up and onto
the wing to make it a little narrower to install
into the fuselage. Push the wing past center to
move the aileron back into position, then center
the wing.
3. Slide the horizontal stabilizer into the fuselage,
being careful not to damage any of the alignment
tabs. You may need to move the horizontal
fuselage out of the vertical fuselage slightly to get
the stabilizer into position.
13

4. Align the stabilizer with the horizontal fuselage.
Use foam-safe CA to glue the stabilizer to ONLY
the horizontal fuselage.
5. Align the wing with the horizontal fuselage.
Use foam-safe CA to glue the wing to ONLY the
horizontal fuselage.
Hint: Use the holes for the aileron servos to
aid in the alignment between the horizontal
fuselage and wing.
Note: There are slots at the front and rear of
the wing. Lightly lift the area and apply CA
underneath for a greater gluing area.
14

Important: If you plan on using CA accelerator,
make sure it is foam compatible. Many
accelerators will destroy the foam used on this
model.
6. Place the motor mount in position to aid in
the alignment of the vertical and horizontal
fuselage pieces. DO NOT glue the mount until
instructed to do so. Position the horizontal and
vertical fuselage pieces until the mount rests flush
against both.
7. Apply foam-safe CA to the joint between the
vertical and horizontal fuselage pieces from
the leading edge of the wing to the front of the
fuselage. Use a square to make sure the two
pieces are aligned. Apply CA to both the top and
bottom of the vertical fuselage.
15

8. Complete gluing the vertical and horizontal
fuselage pieces together. Continue to use a
square to keep both pieces in alignment.

Installing the Bracing
Required Parts
Assembled airframe
Carbon rod, 9 7/8" (250mm) (2)
Carbon rod, 9 1/2" (240mm) (2)
Carbon rod, 4 3/4" (120mm) (2)
Carbon rod, 4 1/2" (113mm) (4)
Carbon rod, 4 1/8" (105mm) (4)
Required Tools and Adhesives
Foam-safe CA, Medium
Sandpaper
Hobby knife
Note: It is important that each carbon
rod attaches to the next, and to the
carbon blade spars on the edges of the
foam. This is necessary to provide the
stiffest airframe possible.
1. Locate the two 4 3/4" (120mm) carbon rods.
Pass the rods through the fin and stabilizer.
Use foam-safe CA to glue the rods to the fin
ONLY at this time.
17

2. Place the 4 1/2" (113mm) carbon rods on the
bottom of the stabilizer to the bottom of the
vertical fuselage. There is a notch in the fuselage
for the rods to rest in. Make sure the rods are
touching each other as well as the carbon blade
spar. Use foam-safe CA to glue the rods at the
fuselage ONLY.
3. Check the alignment of the fin to the stabilizer.
They should be perpendicular to each other.
Check that the rods in the stabilizer are
touching. Use foam-safe CA to glue the rods
into position after checking alignment and that the
rods are touching.
18

4. Locate two of the 4 1/8" (105mm) carbon rods.
Install these rods, like the rods installed in Step
3, to the horizontal fuselage. Again, there are
notches for the carbon rods. Make sure the rods
are touching the previously installed rods and the
pre-installed carbon blade spars on the edges of
the foam.
5. The next rod to install is the 4 1/2" (113mm)
rod from the rod in Step 4 to the bottom of
the vertical fuselage.
19

6. To complete the fuselage bracing, install a 4 1/8"
(105mm) rod from the previous rod back down to
the horizontal fuselage. You will need to trim the
fuselage to expose the carbon support so the rod
can be glued securely to the brace.
7. Check the joints in Steps 1 through 6 to ensure
you have a nice fillet of CA at every junction
where you have glued the carbon rods to each
other and the fuselage. Apply additional CA if
necessary to create this fillet.
8. Installing the wing bracing is similar to installing
the fuselage bracing, as you want the rods to be
glued to the carbon bracing that has been pre-
installed on the wing and fuselage. The longer
97/8" (250mm) rod is positioned toward the
aileron, while the shorter 9 1/2" (240mm) rod is
toward the leading edge. The rods are staggered
and fit into notches in the fuselage. Make sure
the rods are straight and are not flexing the
wing. Use foam-safe CA to glue the rods in
position. The wing should be flat and parallel
to the horizontal stabilizer, while also being
perpendicular to the vertical fuselage.
