The Carbon-Z Yak 54 is a semi scale 3D performer designed by Quique Somenzini. It features a new construction
process that brings foam constructed airplanes onto the same playing field as balsa. Carbon-Z material comes
from a process that combines foam with carbon fiber reinforcements, making it stronger than balsa but with no
additional weight.
The foam outer material is designed to survive minor crashes with minimal damage. However, in the event
of a crash, the Carbon-Z Yak 54 is designed to be easy to repair. Minor dents to the foam outer surface can be
repaired easily in the field. The aircraft is also modularly designed to make replacement of damaged sections
easy. The resulting product is a great flying plane that will spend more time in the air and less time in the
workshop. The Carbon-Z Yak 54 will be tuned to specifications recommended by Quique Somenzini himself. All
components, from the servos to the motor, have been selected and tuned to optimize the plane’s performance.

Charging the Flight Battery
Your E-flite Carbon-Z Yak 54 comes with a DC balancing
charger and 4S Li-Po battery. You must charge the
included Li-Po battery pack with a Li-Po specific charger
only (such as the included charger). Never leave the
battery and charger unattended during the charge
process. Failure to follow the instructions properly
could result in a fire. When charging, make certain
the battery is on a heat-resistant surface. Charge the
battery pack while you are assembling the aircraft. You
will need the flight battery to confirm proper aircraft
operation in future steps.
DC Li-Po Balancing Charger Features
• Charges 3-to 4-cell lithium polymer battery packs
• Variable charge rates from 500mAh to 3-amp
• Simple single push-button operation
• LED charge status indicator
• LED cell balance indicator
• Audible beeper indicates power and charge status
• 12V accessory outlet input cord
Specifications
• Input power: 12V DC, 3-amp
• Charges 3- to 4-cell Li-Po packs with minimum
capacity of 500mAh
4S 14.8V 2800mAh Li-Po Battery Pack
The E-flite 4S Li-Po battery pack features a balancing
lead that allows you to safely charge your battery pack
when used with the included E-flite Li-Po
balancing charger.
WARNING: Failure to use the proper charger for a
Li-Po battery can result in serious damage, and if left
charging long enough, will cause a fire. ALWAYS use
caution when charging Li-Po batteries.
The Battery Charging Process
1. Charge only batteries that are cool to the touch and
are not damaged. Look at the battery to make sure
it is not damaged e.g., swollen, bent, broken or
punctured.
2. Attach the input cord of the charger to the
appropriate power supply (12V accessory outlet).
3. When the Li-Po charger is correctly powered up,
there is an approximate 3-second delay, then an
audible “beep” and the green (ready) LED will flash.
4. Turn the control on the Amps selector so the arrow
points to the charging rate required for the Battery.
(See chart, for example the Yak 54 2800mAh Li-Po
battery will charge at 3.0 amps.) DO NOT change the
charge rate once the battery begins charging.
5. Move the cell selector switch to 3-cell or 4-cell for
your battery.
6. Connect the Balancing Lead of the Battery to the
3-cell (4 pins) or 4-cell (5 pins) Charger port.
7. The green and red LEDs may flash during the
charging process, when the charger is balancing
cells. Balancing prolongs the life of the battery.
8. When the battery is fully charged, an audible beep
will sound for about 3 seconds, and the green LED
will shine continuously.
9. Always unplug the battery from the charger
immediately upon completion of charging.
CAUTION: Overcharging a battery can cause a fire.

WARNING: Selecting a charge rate higher than 1x
(one times) the battery capacity may cause a fire.
Low Voltage Cutoff (LVC)
When the motor pulses, please land the aircraft
immediately and recharge the flight battery.
When a Li-Po battery is discharged below 3V per
cell, it will not hold a charge. The Carbon-Z Yak 54
Electronic Speed Control protects the flight battery
from over-discharge using Low Voltage Cutoff (LVC).
Before the battery charge decreases too much, LVC
removes power from the motor. Power to the motor
pulses, showing that some battery power is reserved
for flight control and safe landing.
Disconnect and remove the Li-Po battery from the
aircraft after use to prevent trickle discharge. Fully
charge your Li-Po battery before storing it.
During storage make sure battery charge does not go
below 3V per cell.
Note: The speed control is programmed for 4S LVC.

Transmitter and Receiver Binding
Binding is connecting a transmitter to an aircraft
receiver wirelessly or electronically so the aircraft
receiver recognizes the transmitter GUID (Globally
Unique Identifier) code. Binding is necessary for
proper operation.
Note: The Carbon-Z Yak 54 BNF requires a DSM2 full
range (high power) transmitter. Any JR or Spektrum
DSM2 transmitter can bind to the Spektrum AR600
receiver. Due to the aerobatic nature of the Carbon-Z
Yak 54, we recommend using a transmitter with
adjustable exponential and dual rates. Please visit
www.bindnfly.com for a complete list of
compatible transmitters.
Note: When using a Futaba transmitter with a
Spektrum module,you may need to reverse the
throttle channel.
6
Activity
CAUTION: ALWAYS power on the transmitter
before connecting the flight battery to the aircraft
ESC. ALWAYS disconnect the flight battery from the
aircraft ESC before powering off the transmitter.
Additional Binding Information
Before each flight, power on the transmitter and wait
about 5 seconds before powering on the ESC. The
transmitter scans and secures two radio frequencies
for aircraft control. When the flight battery is
connected too quickly for the transmitter to make
frequency selection, the transmitter and receiver may
not connect. When there is no connection, leave the
transmitter powered on, disconnect the flight battery
then reconnect the flight battery to the receiver.

Range Check and Pre-Flying Tips
Range Check your Radio System
After final assembly, range check the radio system
with the Carbon-Z Yak 54. Refer to your specific
transmitter instruction manual for range test
information. It is helpful to have another person
assist with the range check and secure the airplane.
If assistance is not available, secure the tail of the
aircraft before increasing the throttle.
Before Each Flying Session
• Always make sure the dual rates switch is set to
LOW rates for takeoff. We recommend LOW rates
for your initial flights. The Carbon-Z Yak 54 is VERY
maneuverable on high rates and requires a lot of
experience to handle properly.
• It is recommended to set the timer for 5 minutes
before take off.
Flying Tips and Repairs
Flying
Always follow local ordinances when choosing a
location to fly. Choose a wide-open space for flying
your E-Flite Carbon-Z Yak 54 BNF or PNP. It is ideal for
4. Attach the ESC connector to the throttle channel of
the receiver.
Battery Selection and Installation
• We recommend the E-flite 2800mAh 14.8V 30C
Li-Po battery (EFLB28004S30).
• If using another battery, the battery must be at
least a 30C 2800mAh battery.
• Your battery should be approximately the same
capacity, dimensions and weight as the E-flite
Li-Po battery to fit in the fuselage without changing
the center of gravity a large amount.
• Always make sure your Carbon-Z Yak 54 is
properly trimmed prior to each flight
• Always make sure the receiver, ESC, and battery
are secured in the fuselage.
• Perform a range check according to your
transmitter’s instructions prior to each flight.
• Always make sure that all controls function per the
transmitter input you give. This includes ailerons,
rudder, elevator and throttle.
• Always fully charge the transmitter batteries or
make sure your transmitter has fresh batteries
before you fly.
• Always make sure the servo reversing switches on
the transmitter are set correctly.
CAUTION: Always remove the flight battery from
the aircraft when you are done flying, or when you
are on the way to the flying field.
you to fly at a sanctioned flying field, as the Carbon-Z
Yak 54 is capable of speeds exceeding 70 mph. If you
are not flying at an approved site, always avoid flying
near houses, trees, wires and buildings. You should
also be careful to avoid flying in areas where there
are many people, such as busy parks, schoolyards, or
soccer fields.

EN
Note: The Carbon-Z Yak 54 is a high-performance
aircraft, designed to handle the stresses of highenergy aerobatic flight. Due to the construction of the
Carbon-Z Yak 54, the airframe is capable of handling
high G maneuvers.
Takeoff
Choose a large open area with a smooth surface for
takeoff. Confirm your transmitter dual rate switch is
set to LOW rates for takeoff. Point the nose of the
aircraft into the wind.
Landing
Set to Low Rate, start the landing approach by
reducing throttle to 1/4 or less to slow the aircraft. Fly
the aircraft down to about 1-2 feet above the runway.
Slowly reduce power until the throttle is in the off
position. Apply up elevator as the aircraft settles
to the runway. The Carbon-Z Yak 54 can do a main
landing gear landing, or two-point landing, where the
aircraft touches down on the main wheels first and
the tailwheel is off the ground. The Carbon-Z Yak 54
can also land in three-point attitude when all three
wheels touch the runway at the same time.
Repairs
Thanks to the construction of the Carbon-Z Yak 54,
repairs to the foam can be made using virtually any
adhesive (hot glue, regular CA, epoxy, etc). When
parts are not repairable, see the Replacement Parts
List for ordering by item number.
Note: The Carbon-Z Yak 54 can be taken apart and
put back in the box for storage or transportation.
2010 Official Academy of Model Aeronautics Safety Code
Effective January 1, 2010
GENERAL
1. A model aircraft shall be defi ned as a nonhuman carrying device capable of sustained flight
in the atmosphere. It shall not exceed limitations
established in this code and is intended to be
used exclusively for recreational or
competition activity.
2. The maximum takeoff weight of a model aircraft,
including fuel, is 55 pounds, except for those fl
own under the AMA Experimental Aircraft Rules.
3. I will abide by this Safety Code and all rules
established for the flying site I use. I will not
willfully fly my model aircraft in a reckless and/or
dangerous manner.
4. I will not fl y my model aircraft in sanctioned
events, air shows, or model demonstrations until
it has been proven airworthy.
5. I will not fl y my model aircraft higher than
approximately 400 feet above ground level, when
within three (3) miles of an airport without
notifying the airport operator. I will yield the
right-of-way and avoid fl ying in the proximity of
full-scale aircraft, utilizing a spotter when
appropriate.
6. I will not fl y my model aircraft unless it is
identified with my name and address, or AMA
number, inside or affi xed to the outside of the
model aircraft. This does not apply to model
aircraft fl own indoors.
7.
I will not operate model aircraft with metal-blade
propellers or with gaseous boosts (other than air),
nor will I operate model aircraft with fuels
containing tetranitromethane or hydrazine.
8. I will not operate model aircraft carrying
pyrotechnic devices which explode, burn, or
propel a projectile of any kind. Exceptions include
Free Flight fuses or devices that burn producing
smoke and are securely attached to the model
aircraft during flight. Rocket motors up to a
G-series size may be used, provided they remain
firmly attached to the model aircraft during flight.
Model rockets may be flown in accordance with
14
the National Model Rocketry Safety Code;
however, they may not be launched from model
aircraft. Officially designated AMA Air Show
Teams (AST) are authorized to use devices and
practices as defined within the Air Show Advisory
Committee Document.
9. I will not operate my model aircraft while under
the influence of alcohol or within eight (8) hours
of having consumed alcohol.
10. I will not operate my model aircraft while using
any drug which could adversely affect my ability

on a flightline or in a fl ight area as a pilot or
while under fl ight instruction.
12. When and where required by rule, helmets must
be properly worn and fastened. They must be
OSHA, DOT, ANSI, SNELL or NOCSAE approved
or comply with comparable standards.
RADIO CONTROL
1. All model flying shall be conducted in a manner
to avoid over fl ight of unprotected people.
2. I will have completed a successful radio
equipment ground-range check before the first
flight of a new or repaired model aircraft.
3. I will not fly my model aircraft in the presence of
spectators until I become a profi cient flier, unless
I am assisted by an experienced pilot.
4. At all flying sites a line must be established, in
front of which all flying takes place. Only
personnel associated with flying the model
aircraft are allowed at or in front of the line. In the
case of airshows demonstrations straight line
must be established. An area away from the line
must be maintained for spectators. Intentional
flying behind the line is prohibited.
5. I will operate my model aircraft using only radio
control frequencies currently allowed by the
Federal Communications Commission (FCC).
Only individuals properly licensed by the FCC are
authorized to operate equipment on Amateur
Band frequencies.

3. I will use an effective device to extinguish any
fuse on the model aircraft after the fuse has
completed its function.
CONTROL LINE
1. I will subject my complete control system
(including the safety thong where applicable) to
an inspection and pull test prior to flying. The
pull test will be in accordance with the current
Competition Regulations for the applicable model
aircraft category. Model aircraft not fitting a
specific category shall use those pull-test
requirements as indicated for Control Line
Precision Aerobatics.
2. I will ensure that my flying area is clear of all
utility wires or poles and I will not fly a model
aircraft closer than 50 feet to any aboveground
electric utility lines.
