Introduction

Required Radio Equipment

Thank you for purchasing the E-flite™ Brio 10 ARF. If
anybody knows what precision feels like, 3-time World
Champion and 2-time US Champion Quique Somenzini
certainly does. And he has poured all this experience into
the design of the Brio 10—a 10-size replica of the same
F3A plane he used to win the 2005 US Nats. At the heart
of its performance is a low aspect ratio wing that moves the
center of lift closer to the fuselage. The result is an electric
pattern plane with outstanding roll rates and a locked-in feel
that will give you the confidence to fly artistic aerobatics with
absolute precision.

Specifications

Wingspan: 41 in (1040mm)
Length: 40 in (1015mm)
Wing Area: 325 sq in (21 sq dm)
Weight w/o Battery: 25–29 oz (710–820g)
Weight w/ Battery: 28–34 oz (795–965g)

You will need a minimum 6-channel transmitter (for proper
mixing capabilities), crystal, 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. JR’s XP9303 has every possible programming
feature a precision plane like the Brio 10 would need. This,
combined with a feather-light JR 610UL, is the same system
Quique uses in his Brio 10.

Important Information About Motor

Selection

The Brio 10 has two firewall options that are designed
to easily utilize our recommended E-flite™ Park 480 BL
Outrunner Motor, 1020Kv, the optional Power 10 BL
Outrunner Motor, 1100Kv or our optional Six-Series BL
2700Kv Motor (28mm) with a gearbox. First determine
what power system you will be using, an outrunner or 6­pole inrunner with a gearbox. You can also use the included
Firewall Stick Mount and easily mount our Six-Series with
a gearbox, or even our Park 480 Outrunner when you use
the included Outrunner Stick Mount. By using the included
outrunner standoffs, mounting a Power 10 Outrunner is also
very easy.

If it's Quique Somenzini's lightweight setup you are looking
for, try using our park 480 Outrunner, 1020 Kv motor
(EFLM1505). For high-speed F3A flying only, we recommend
E-flite’s Power 10 BL Outrunner motor (EFLM4010A). This
setup will weigh about 3 ounces more than the lightweight
alternative.

For a geared alternative with strong vertical power and
speed, try the Six-Series BL 2700Kv Motor (28mm)
(EFLM2005).

Using the Manual

Before Starting Assembly

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.

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.

Before beginning the assembly of your Brio 10, remove
each part from its bag for inspection. Closely inspect the
fuselage, wing panels, rudder and stabilizer for damage.
If you find any damaged or missing parts, contact the place
of purchase.

Note on Lithium Polymer Batteries

Lithium Polymer batteries are significantly
more volatile than alkaline or Ni-Cd/Ni­MH 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.

/

" (58mm), if your

4

flying site has rough terrain. By using a larger
wheel, you will not be able to use the included
wheel pants.

11

 2. Slide the landing gear into the fuselage. The

holes in the gear will only line up when installed
correctly. Slide a #4 washer onto each of the four
4-40 x 1/2" socket head screw. Place a drop of
threadlock onto each of the 4-40 screws. Slide the
screws through the landing gear and into the pre­installed blind nuts. Use a 3/32" hex wrench to
tighten each of the screws.

 3. Slide the 2mm x 25mm bolt through the

landing gear. Secure the bolt using a 2mm nut
and threadlock.

12

  4. Thread a 2mm nut 1/8" (3mm) from the first

nut. Use threadlock or thin CA to keep the nut
from rotating. Slide the wheel on and thread a
final 2mm nut onto the screw, using threadlock or
thin CA to keep the nut from rotating.

Note: Be very careful when using thin CA as
not to glue the wheel so it won’t rotate on the
2mm x 25mm screw.

  5. Slide the wheel pant into position and

secure it using the 2mm x 8mm wood screw.
Don’t over-tighten the screw which can damage
the wheel pant.

13

 6. Repeat Steps 4 through 6 for the remaining

wheel and wheel pant.

 7. Drill two 1/8" (3mm) holes in the tail for the

tail skid.

Aileron Hinging

Required Parts

• Wing (left and right)

• Aileron (left and right)

• CA hinges (6)

Required Tools and Adhesives

• T-pins • Thin CA

• Drill • Paper towel

• Drill bit: 1/16" (2mm)

  1. Locate the positions for the hinges. Drill a

1/16" (2mm) hole in the center of each slot of
both the wing and aileron. This creates a tunnel
for the CA, allowing the CA to penetrate into the
hinge better, bonding the hinges more securely.

15

  2. Slide three hinges into the slits in the aileron.

Center the slot in the hinge with the hole drilled
in Step 1. Place a T-pin in each hinge to prevent
it from being pushed into the wing when
installing the aileron.

Note: Do not use CA accelerator during the
hinging process. The CA must be allowed to
soak into the hinge to provide the best bond.
Using accelerator will not provide enough time
for this process.

  3. Slide the aileron into position. Check to

make sure it can move without interference at
the wing root and wing tip. Remove the T-pins
and apply Thin CA to each hinge. Make sure
the hinge is fully saturated with CA. Use a paper
towel to clean up any excess CA from the wing
and aileron. Make sure to apply CA to both sides
of the hinge.

16

  4. Firmly grasp the wing and aileron and gently

pull on the aileron to ensure the hinges are
secure and cannot be pulled apart. Use caution
when gripping the wing and aileron to avoid
crushing the structure.

  5. Work the aileron up and down several

times to work in the hinges and check for
proper movement.

 6. Repeat Steps 1 through 5 for the remaining

aileron.

  1. Use 6-minute epoxy to attach the control horn

to the aileron. Make sure the horn is fully seated
in the opening.

  2. Attach a 6" servo extension to the aileron

servo. Secure the extension using string or a
commercially available clip.

18

  3. Place the servo in the wing. Guide the servo

lead out through the opening at the wing root.
Secure the aileron servo using the screws
provided with the servo.

  4. Attach the 3" (75mm) pushrod to the control

horn. Start the wire from the wing tip side of the
control horn.

19

 5. Attach the micro control connector to a long

3D servo arm. Be sure to use the included
retainer to secure the micro control connector
to the servo arm. Remove the remaining unused
part of the servo arm.

  6. Turn on the radio system and center the

aileron trim and stick. Make sure the aileron servo
is operating properly using the transmitter. Slide
the pushrod wire through the micro connector.
Install the servo arm parallel to the aileron hinge
line. Center the aileron, and secure the position
of the wire using the 2mm x 4mm screw and a
Phillips screwdriver.

Note: Ensure all channel sub trims are at 0.

• 4-40 x 1/2" socket head screw (2)

Required Tools and Adhesives

• Hex wrench: 3/32"

 1. Slide the wing tube into a wing panel.

 2. Remove the hatch from the fuselage. Slide

the wing panel with tube into position on
the fuselage.

21

 3. Slide a #4 washer onto a 4-40 x 1/2" socket

head screw. Slide the remaining wing panel into
position. Secure the panels using 4-40 x 1/2"
socket head screws with #4 washers (silver) using
a 3/32" hex wrench.

22

Stabilizer, Elevator & Rudder

Required Parts

• Fuselage w/wing installed

• Stabilizer • Rudder

• Elevator • CA hinge (9)

Required Tools and Adhesives

• Hobby knife • Felt-tipped pen

• Ruler • T-pins

• Thin CA • Hobby knife

 1. Hinge the elevator and stabilizer, using the same

process as described in Aileron Hinging. Use 6
hinges for this process.

 2. Cut the rear of the fuselage using a hobby knife

to allow the stabilizer to be slid into the fuselage.

Caution: Be VERY careful when cutting the rear
of the fuselage with the hobby knife. Always
cut away from yourself and your fingers in case
the knife slips.

23

A A

A=A

 3. Position the stabilizer into the slot in

the aft end of the fuselage. Slide the stabilizer
as far forward as possible. Center the stabilizer
in the slot in the fuselage.

 4. Measure from the stab tip to the wing tip. Adjust

the stab until the measurements are equal.

24

 5. View the airframe from the rear and make sure

the wing and stab are parallel. If not, lightly sand
the stab saddle until they are.

 6. Double-check the adjustments from Steps 1

through 3. Use a felt-tipped pen to trace the
outline of the fuselage onto the top and bottom of
the stabilizer.

25

 7. Use a sharp hobby knife to cut the covering

slightly inside the lines drawn. Be very careful
not to cut into the underlying wood, as this will
weaken the stab and cause it to fail in flight.

Note: You can use a soldering iron or hot
knife instead of a regular old hobby knife.
This will help in reducing the chance of
damaging the wood.

 8. Slide the stab and elevator back into position.

Again, check the alignment and make sure
everything lines up. Wick Thin CA into the
joint between the fuselage and stabilizer. Make
sure to glue both top and bottom. Do not use
accelerator—allow the CA to wick in as far as
possible, providing the best bond.

26

 9. Install the four carbon rods between the fuselage

and stabilizer as shown. Glue the rods to the
stabilizer and fuselage using 6-minute epoxy.

 10. Attach the rudder using three CA hinges. Use

the technique as described in Aileron Hinging for
this procedure.

27

 4. Slide the gearbox into position on the motor

mount. Use a 1/16" (1.5mm) drill to drill a hole
on each side of the gearbox and into the mount.
Stagger the holes so the screws will not interfere
with each other. Secure the gearbox using three
#2 x 8mm screws.

Cowling, ESC and Propeller Installation

Required Parts

• Fuselage

• Cowling

• Prop adapter

• 3mm x 8mm sheet metal screw (4)

• Electric propeller

• Ultra Plug, Male/Female Set (WSD1300)

• Spinner, 1

• 40-Amp Brushless ESC

Required Tools and Adhesives

Important Information About Your Brushless ESC

Make sure your ESC brake is programmed
to ‘off’. Also, be sure to use an ESC with the
proper 9V cutoff when using 3-cell Li-Po packs.
We suggest this cutoff to be of the soft variety
to prevent hard motor cutoffs during low level
3D flying.

Some 35A–40A brushless ESC on the market
either warn against running four (4) sub-micro
servos or do not specify this setup will work.
The reason is because oftentimes running four
sub-micro servos with a 3-cell Li-Po battery
are outside the range of the controller’s BEC
capability. Most controllers on the market can
only handle 800mA to 1 Amp continuous draw
when using a 3-cell Li-Po battery, some even
lower. However, many consumers are
still running four sub-micro servos with success.
If you choose to attempt this, you must set up
your plane properly and check the current
draw (under load) of your radio system,
making sure it is within the specifications of the
controller’s BEC. Be sure to put the ESC in a
position to get the best airflow since cooling
will help the BEC capacity.

Our E-flite 40A Brushless ESC (V2) (EFLA312B)
is equipped with a higher rated, heavy-duty
BEC that can dissipate more heat and handle
higher wattage when using a 3-cell Li-Po
battery. Make sure you specify this part number
to ensure you are getting the correct controller.
You should always still check your setup first
before flying.

Some other alternatives are available:

 A. Disable the controller’s BEC per manufacturer’s

instructions and use a flight pack battery.

 B. Buy a device such as an external BEC that is

specified to handle more current.

 C. Select a controller such as the Castle

Phoenix 35 or our updated E-flite™ 40A Brushless
ESC (EFLA312B) that has a higher rated, heavy­duty BEC.

37

 1. Connect the ESC to the motor and secure the

ESC to the inside of the fuselage using hook and
loop material and/or a tie wrap. The location
of the ESC may be changed depending on
the length of the motor wires, type of ESC and
necessity to move the ESC to achieve the correct
Center of Gravity.

 2. Use the radio system and motor battery to

determine the direction of rotation of the
propeller. When connected correctly it should
rotate counter-clockwise when viewed from the
front of the aircraft. If not, follow the directions
included with the speed control to correct the
direction of rotation.

 3. Attach the cowling using four 3mm x 8mm sheet

metal screws.

38

Note: Steps 4 through 6 cover the installation
of the propeller when using an Outrunner motor.
Skip to Step 7 for the installation of
the propeller when using an Inrunner motor
and gearbox.

 4. If using an Outrunner motor, it may be necessary

to ream a larger opening into the backplate of
your E-flite™ spinner to fit the shaft size of the
prop adapter shaft. Slide the aluminum prop
adapter shaft and collet onto the motor to check
the size of the hole in the propeller.

39

Note: Two spacers have been provided that
are placed between the propeller and spinner
backplate. Use the thin spacer for low-pitch
propellers, the thick spacer for high-pitch
propellers. This will prevent the blades of the
propeller from contacting the spinner backplate.

 5. Slide the spinner backplate onto the gearbox

shaft. Slide the propeller ontot he shaft then
secure the propeller and spinner backplate
using the supplied aluminum prop adapter cone.

Note: It is very important that you check to be
sure the propeller is balanced before installing
onto the shaft. An unbalanced propeller will
cause performance issues. Some propellers will
need the center hole drilled out to fit the shaft
size of your outrunner. It is very important the
hole is drilled concentric or it can cause the
propeller to be unbalanced.

 6. Snap the spinner cone onto the

spinner backplate.

40

 7. Insert the 'hex to round' adapter onto the shaft.

Then, slide the 6mm washer included with your
gearbox onto the output shaft.

 8. Slide the propeller onto the gearbox shaft. Slide

the spacer included with the spinner onto the
gearbox shaft in front of the prop as needed.

Note: Two spacers have been provided that
are placed between the propeller and spinner
backplate. Use the thin spacer for low-pitch
propellers, the thick spacer for high-pitch
propellers. This will prevent the blades of the
propeller from contacting the spinner backplate.

41

 9. Slide the spinner backplate onto the gearbox

shaft. Secure the propeller and spinner backplate
using a 4mm washer and 4mm locknut. Make
sure not to over-tighten the 4mm locknut.

 10. Snap the spinner cone onto the

spinner backplate.

Rudder and Elevator Servos

Required Parts

• Fuselage

• Plastic rudder horn

• Pull-pull cable

• 2mm x 4mm screw (3)

• 3" (75 mm) pushrod wire

• Brass cable keepers (4)

• Micro control horn w/backplate

• Micro control connector w/retainer (3)

• Sub-micro servo (2)

• 12" (305 mm) servo extension (2)

• Micro cable adjust connector (2)

Required Tools and Adhesives

• Hobby knife

• Phillips screwdriver (small)

• Medium CA

• Thin CA

 1. Secure a 12" (305 mm) servo extension to one of

the servos. Mount the elevator servo in the aft end
of the fuselage using the hardware provided with
the servo. Secure the extension using string or a
commercially available clip.

43

 2. Attach the micro control horn to the elevator

using a micro control horn backplate. Apply a
few drops of medium CA to the backplate.

 3. Install the micro control connector onto the

elevator servo arm. Pass the elevator pushrod
wire through the connector. With the radio on
and elevator trim centered, center the elevator.
Secure the elevator pushrod wire using the 2mm x
4mm screw and a small Phillips screwdriver.

Note: Make sure to set the elevator sub-trim
to 0.

44

Note: An optional rudder servo location has
been provided at the rear of the fuselage if
using heavier motors and you choose not to use
the pull-pull system. The installation procedure
is identical to the elevator servo installation,
except the covering must be removed from the
fuselage first.

At this time, we suggest that you trial fit the
battery and receiver into the front of the
fuselage and follow the steps outlined on page
49 and check the CG location. If it is nose
heavy, you might consider installing the servo
at the optional rear location. If you do not
anticipate an issue, than proceed with Step 4
and install the rudder servo in the fuse for a
pull-pull system.

Note: Steps 4 through 10 illustrate the
installation of the pull-pull system. When
using the pull-pull system, continue on starting
at Step 6.

45

 4. Lightly sand both sides of the middle section of

the plastic rudder control horn before installing so
the CA wicks better. Install the rudder control horn
for the rudder using medium CA. Square the horn
to the control surface.

Note: The control horn has ears that will allow it
to only slide into the rudder from one direction.
These ears rest against the side of the rudder
when installed correctly.

 5. Mount the rudder servo inside the fuselage using

the hardware provided with the servo. Install
two micro control connectors into a long servo
arm. Secure them using the control connector
backplates. With the radio system on, center the
rudder trim and sub trim, then install the servo
arm on the rudder servo.

46

 6. Use tape to hold the rudder in neutral. Slide a

cable crimp onto the control cable. The cable
then goes through the horn, then back through
the crimp twice. Pull the wire tight, and then use
pliers to secure the crimp. Add a small drop of
thin CA inside the brass crimp to help secure the
wire. Wipe away any excess immediately.

 7. Slide the micro cable adjust connector into

the micro control connector and use a 2mm x
3mm screw to hold it in position. Repeat Step 7,
installing the cable through the cable connector.

47

 8. The cables will cross inside the fuselage to

get the proper geometry for the rudder to
operate correctly.

 9. Remove the tape from the control surface. Install

the second cable following Steps 9 through

11. Tension the cables lightly using the cable
connectors to pull the surface into neutral.

48

Final Assembly

Required Parts

• Fuselage

• Receiver

• 3-cell 11.1V Li-Po, 16GA

• Hook and loop tape (2)

• Canopy hatch

Required Tools and Adhesives

• Thin CA

Optional Parts

• Hook and loop strap

 1. Check to make sure all servo wires and ESC

wires can reach the location of the receiver before
mounting the receiver. Cut a piece of the hook
and loop tape to the size of the receiver. Install
the receiver using the hook and loop. Plug in
the rudder, elevator, and aileron servos (after
attaching the wing). Route the receiver antenna to
the rear of the plane.

Note: Do not cut the receiver antenna, as
this will greatly reduce the range of the radio
system.

Hint: Position the receiver so the ailerons can be
plugged in easily.

49

 2. Install the battery in the fuselage using the

remaining piece of hook and loop material. The
battery location may vary but we anticipate that
it will need to be mounted at the farthest back
location on the battery tray in order to achieve
the correct Center of Gravity.

Hint: It is recommended you may use a piece of
hook and loop strapping around the battery to
help secure it in position.

 3. Install the canopy hatch by sliding it under the

cowling, then snapping it down onto the fuselage.
A magnet holds the aft end of the hatch in
position during flight.

50

Control Throws & Exponential

 1. Turn on the transmitter and receiver of your

Brio 10. 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.

 2. Check the movement of the elevator with the radio

system. Moving the elevator stick down will make the
airplane elevator move up.

 3. Check the movement of the ailerons with

the radio system. When you move the stick
left, the left aileron will go up and the right aileron will
go down. When you move the
stick right, the right aileron will go up and
the left aileron will go down.

These are general guidelines measured from our own flight
tests. You can experiment with higher rates to match your
preferred style of flying.

Center of Gravity

An important part of preparing the aircraft for flight is
properly balancing the model.

Caution: Do not inadvertently skip this step!

The recommended Center of Gravity (CG) location for
the Brio 10 is 3

/

" (110mm) behind

the leading edge of the wing against the fuselage. Use
this CG range for the first flights until you have become more
experienced.

The CG range was determined from our flight tests. The
forward range is better suited for sport and precision
aerobatics, while the aft (rear) location is for more wild
and 3D flying. You can experiment with the best locations

to suit your flying style. Quique Somenzini flies at the 4

2005 Official AMA National Model Aircraft Safety Code

GENERAL

1) I will not fly my model aircraft in sanctioned events,
air shows or model flying demonstrations until it
has been proven to be airworthy by having been
previously, successfully flight tested.

2) I will not fly my model higher than approximately
400 feet within 3 miles of an airport without notifying
the airport operator. I will give right-of-way and avoid
flying in the proximity of full-scale aircraft. Where
necessary, an observer shall be utilized to supervise
flying to avoid having models fly in the proximity of
full-scale aircraft.

3) Where established, I will abide by the safety rules
for the flying site I use, and I will not willfully or
deliberately fly my models in a careless, reckless and/
or dangerous manner.

4) The maximum takeoff weight of a model is 55
pounds, except models flown under Experimental
Aircraft rules.

5) I will not fly my model unless it is identified with
my name and address or AMA number on or in the
model. (This does not apply to models while being
flown indoors.)

6) I will not operate models with metal-bladed
propellers or with gaseous boosts, in which gases
other than air enter their internal combustion
engine(s); nor will I operate models with extremely
hazardous fuels such as those containing
tetranitromethane or hydrazine.

RADIO CONTROL

1) I will have completed a successful radio equipment
ground range check before the first flight of a new or
repaired model.

2) I will not fly my model aircraft in the presence
of spectators until I become a qualified flier, unless
assisted by an experienced helper.

54

2005 Official AMA National Model Aircraft Safety Code

3) At all flying sites a straight or curved line(s) must
be established in front of which all flying takes place
with the other side for spectators. Only personnel
involved with flying the aircraft are allowed at or in
front of the flight line. Intentional flying behind the
flight line is prohibited.

4) I will operate my model using only radio control
frequencies currently allowed by the Federal
Communications Commission. (Only properly licensed
Amateurs are authorized to operate equipment on
Amateur Band frequencies.)

5) Flying sites separated by three miles or more
are considered safe from site-to-site interference,
even when both sites use the same frequencies. Any
circumstances under three miles separation require a
frequency management arrangement, which may be
either an allocation of specific frequencies for each site
or testing to determine that freedom from interference
exists. Allocation plans or interference test reports shall
be signed by the parties involved and provided to
AMA Headquarters.

Documents of agreement and reports may exist
between (1) two or more AMA Chartered Clubs,
(2) AMA clubs and individual AMA members not
associated with AMA Clubs, or (3) two or more
individual AMA members.

6) For Combat, distance between combat engagement
line and spectator line will be 500 feet per cubic inch
of engine displacement. (Example: .40 engine = 200
feet.); electric motors will be based on equivalent
combustion engine size. Additional safety requirements
will be per the RC Combat section of the current
Competition Regulations.

7) At air shows or model flying demonstrations, a
single straight line must be established, one side of
which is for flying, with the other side for spectators.

8) With the exception of events flown under AMA
Competition rules, after launch, except for pilots or
helpers being used, no powered model may be flown
closer than 25 feet to any person.

9) Under no circumstances may a pilot or other person
touch a powered model in flight.
