Leyland, the Sobré 3D ARF has superb slow flight responsiveness
so you can fly high-alpha 3D with authority.
Its carbon fiber reinforced Depron foam construction that provides
the solid, precise feel of a balsa profile plane without the weight.
This allows you to fly the Sobré 3D either inside or outside.
The Sobré 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 vibrant screen printed trim
scheme.
Carbon Rod Reinforcement
Much of the exceptional flight performance of the Sobré 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 (
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.
) are performed once, while steps with two circles ( )

You will need a minimum 6-channel transmitter (for proper
mixing and dual rate capabilities), crystals, micro receiver, and
four 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.
If you own the Spektrum DX7 radio, just add the AR6100
DSM2® 6-channel receiver and four of our E-flite S60 Super
6-gram Sub-Micro servos (EFLRS60).

Note on Lithium Polymer Batteries
Limited Warranty
Lithium Polymer batteries are significantly more
volatile than alkaline or Ni-Cd/Ni-MH batteries used
in RC applications. All manufacturer’s instructions
and warnings must be followed closely. Mishandling
of Li-Po batteries can result in fire. Always follow the
manufacturer’s instructions when disposing of Lithium
Polymer batteries.
Warning
An RC aircraft is not a toy! If misused, it can cause serious bodily
harm and damage to property. Fly only in open areas, preferably
at AMA (Academy of Model Aeronautics) approved flying sites,
following all instructions included with your radio.
Keep loose items that can get entangled in the propeller away
from the prop, including loose clothing, or other objects such as
pencils and screwdrivers. Especially keep your hands away from
the propeller.

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.
8 E-flite Sobré 3D Profile Assembly Manual
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.
Note: Trim the hinge tape at the rear of the stabilizer to
provide clearance of the alignment hole.
4. Align the wing with the horizontal fuselage.
Use foam-compatible 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.
Important: If you plan on using CA activator, make sure
it is foam compatible. Many accelerators will destroy the
foam used on this model.
9E-flite Sobré 3D Profile Assembly Manual
5. Measure from the wing tip to the elevator tip on
each side of the airframe. The measurements will
be the same when the stabilizer/elevator has been
aligned with the wing. Use T-pins to hold the stabilizer
in position for the next step.
6. Use foam-compatible CA to glue the stabilizer to
ONLY the horizontal fuselage.
