• If at any time the battery begins to balloon or swell, discontinue use immediately. If charging or discharging, discontinue charging and disconnect.

• When transporting or temporarily storing the battery the temperature range should be from 40–120º F. Do not store battery or model in a car or direct sunlight. If stored in a hot car, the battery can be damaged or even catch fire.

• Li-Po cells should not be discharged to below 3V each under load.

Continuing to use, charge or discharge a battery that is ballooning or swelling can result in fire.

• Store the battery at room temperature in a dry area for best results.

In the case of the Li-Po battery used for the Carbon-Z Yak 54, you will not want to allow the battery to fall below 3V per cell during flight.

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.

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: 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.

WARNING: Selecting a charge rate higher than 1x (one times) the battery capacity may cause a fire.

Low Voltage Cutoff (LVC)

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.

Battery Capacity Maximum Charge Rate

500-1000mAh 500mA 1000-1500mAh 1A 1500-2000mAh 1.5A 2000-2500mAh 2.0A

3000mAh + 3.0A

When the motor pulses, please land the aircraft immediately and recharge the flight battery.

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.

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.



1. Read transmitter instructions for binding to a receiver (location of transmitter’s Bind control).

2. Make sure transmitter is powered o .

3. Install a bind plug in the receiver Batt/Bind port.

4. Connect the  ight battery to the ESC.

5. Turn the ESC switch on to power the receiver. The receiver LED will begin to  ash rapidly.

6. Power on the transmitter while holding the transmitter bind button or switch. Refer to your transmitter’s manual

for binding button or switch instructions.

7. The receiver light will go from  ashing rapidly to  ashing slowly. After 5–10 seconds the light will become solid

indicating the receiver is bound to the transmitter.

8. Remove the bind plug from the receiver.

9. Safely store the bind plug (some owners attach the bind plug to their transmitter using two-part loops and clips).

10. The receiver will keep the binding to the transmitter until a bind plug is put in the receiver Batt/Bind port.

* The throttle will not arm if the transmitter’s throttle control and throttle trim are not put at the lowest position. If you encounter problems, obey binding instructions and refer to transmitter troubleshooting guide for other

instructions. If needed, contact the appropriate Horizon Product Support office.

Adjusting Center of Gravity (CG) by Moving the Battery

The CG location is 6-inches (153mm) forward from trailing edge of the wing tip +/- 1/4inch (6.4mm). This CG location has been determined with the E-flite

14.8V 2800mAh 30C Li-Po battery installed in the middle of the cavity (see picture) and the aircraft positioned upright.

Note: Due to the round wing tips, it is more accurate to measure the CG from the trailing edge. If you want a nose-heavy (forward) or tail-heavy (rear) condition, move the battery forward or to the rear.

6 In

Control Surface Direction Test

Aircraft and transmitter binding should be done before the control direction test. Move the controls on the transmitter to make sure aircraft control surfaces move correctly.

Controls in Reverse in Control Direction Test

If controls respond in the opposite direction reverse the direction for operation of flight controls. Refer to your transmitter’s instructions for changing direction of transmitter flight controls.

Setting for Control Surface Travel

Adjust ATV/travel adjustment on your transmitter until you obtain the following control surface travel. Do not adjust dual rates until you have correctly adjusted the total travel:

Ailerons: 60 to 70mm left and right (both ailerons), measured at the aileron root.

Elevator: 48 to 50mm up and down, measured at the counterbalance leading edge.

Rudder: 60 to 65mm left and right, measured at the counterbalance leading edge.

For information on more

advanced programming, please visit www.e-fliterc.com

Control Surface Travel Exponential Settings

Following are Quique Somenzini’s dual rate and exponential settings for intermediate flyers of the Carbon-Z Yak 54. The settings are based on the ATV set in the previous step.

High rate Expo

Elev. 100% (or 48 mm to 50mm up and down) 50% Ail. 100% Rud. 100%

Low rate Expo

Elev. 22% (or 15mm up and down) 25% Ail. 30% (or 30mm left and right both ailerons) 30% Rud. 60%

Mix: Rudder to Elevator Full left rudder -2% (up elevator) Full right rudder -2% (up elevator)

Note: These control throws were developed by Quique Somenzini for the best performance of the Carbon-Z Yak 54. The small amount of elevator throw on low rate is capable of extreme aerobatics.

Note: only switch to high rate when the plane is flying at slow speed. Never fly at high rate at full airspeed. This airplane is very responsive and pilot can easily lose orientation. Get familiar with the plane first and then try high rate.

Note: for take off and landings, low rate in all control surfaces is strongly recommended.

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.

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.

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

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.

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.
