Charging the Flight Battery
The Battery Charger is designed to safely charge the Li-Po battery,
Caution: All instructions and warnings must be followed exactly. Mishandling of Li-Po
batteries can result in fire, personal injury, or property damage.
Battery warning:
By handling, charging or using the included Li-Po battery
you assume all risks associated with lithium batteries.
If at any time the batteries begin to swell, or balloon, discontinue use immediately!
Charging or discharging a swelling or ballooning battery can result in fire.
Always store the batteries at room temperature in a dry area to extend the life of
the battery. Always transport or temporarily store the battery in a temperature range of
40-120°F. Do not store battery or model in a car or in direct sunlight. If stored in a hot car,
the battery can be damaged or even catch fire.
Never use a Ni-Mh charger. Failure to charge the battery with a compatible charger may
cause fire resulting in personal injury and property damage.
Never discharge Li-Po cells to below 3V.
Never leave charging batteries unattended.
Never charge damaged batteries.
Charging the flight battery
When charging the battery, make certain the battery is on a heat-resistent surface, charge
the battery before assembly of the airplane. Install the fully charged battery to perform
control tests and binding.
| age3
- - р
SEFIMS
Low voltage cut off (LVC) |
When a Li-Po is discharged below 3V per cell, it will not hold a charge. The ESC protects
the flight battery from over-discharge using Low Voltage Cutoff. Before the battery charge
decreases too much, LVC removes power from motor in two ways: (1) Reduces power -
ESC reduces motor power (recommended), (2) Hard cutoff - ESC instantly cuts motor
power when the pre-set Low Voltage Protection Threshold value is reached. These
settings can be changed using the ESC programing guide.

[Important ESC and model information
. The ESC included with the Yak 54 has a safe start. Ifthe motor battery is connected to
the ESC and the throttle stick is not in the low throttle or off position, the motor will not
start until the throttle stick is moved to the low throttle or off position. Once the throttle
stick is moved to the low throttle or off position, the motor will emit a series of beeps.
Several beeps with the same tune means the ESC has detect the cells of the battery.
The count of the beeps equal the cells of the battery. The motor is now armed and will
start when the throttle is moved.
. The motor and ESC come pre-connected and the motor rotation should be correct.
If for any reason the motor is rotating in the wrong direction, simply reverse two of the
three motor wires to change the direction of rotation.
. The motor has an optional brake setting. The ESC comes with the brake switched off
and we recommended that the Yak 54 be flown with the brake off . However, the brake
could be accidentally switched on if the motor battery is connected to the ESC while the
throttle stick is set at full throttle. To switch the brake off, move the throttle stick to full
throttle and plug in the motor battery. The motor will beep one time. Move the throttle
stick to low throttle or the off position. The motor is ready to run and the brake will be
switched off.
. Battery Selection and Installation. We recommend the 14.8V 2600mAh 25C Li-Po
battery. If using another battery, the battery must be at least a 14.8V 2600mAh 25C
battery. Your battery should be approximately the same capacity ,dimension and
weight as the 14.8V 2600mAh 25C Li-Po battery to fit in the fuselage without changing
the center of gravity significantly.
. The specification of the model list as fellow:
Wing span: 1300mm/51.2in

The transmitter and model setup
Before getting started, bind your receiver with your transmitter. Please refer to your
Transmitter Manual for proper operation.
CAUTION: To prevent personal injury, DO NOT install the propeller assembly onto the
motor shaft while testing the control surfaces . DO NOT armthe ESC and do not turn on
the transmitter until the Transmitter Manual instructs you to do so.
Tips: Make sure all control sticks on your radio are in the neutral position (rudder,
elevator, ailerons) and the throttle in the OFF position. Make sure both ailerons
move up and down (travel) the same amount. This model tracks well when the
left and right ailerons travel the same amount in response to the control stick.
1. Move the controls on the transmitter to make sure aircraft control surface move
correctly. See diagrams below. 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.

2. Adjust the servo arms mechanically make sure all servo arms are fully vertical. If not,
adjust the servo arm by using the trim function on your radio.
Note: For computerized transmitters, use the servo/channel sub-trim feature to make each
servo arm fully vertical. Make sure the trims and the sub trims in neutral position before
making some mechanically trim.
3. The standard hole settings for linkage connections are shown by the black arrows in the
the diagram below. You can move the linkage to different hole positions to increase
control surface travel and increase the aerobatics of the airplane.
4. Align the control surfaces well by adjusting the linkage rod in the control connector.
The ailerons align with the wing root fillet, the counterbalance leading edge of the
elevator aligns with the horizontal stabilizer leading edge and the counterbalance
leading edge of the rudder with the vertical stabilizer leading edge.
Note: Use a drop of thread lock on the grub screws before securing the linkage rod.

Check the control throws
1. 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 up and down (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.
2. The dual rates and the Exponential setting for intermediate flyers of FMS Yak 54 are
based onthe ATV set in previous step.
High Rate Expo Low Rate Expo
Aileron 100% 65mm up/down | 60% | 30% 19mm up/down | 30%
Elevator | 100% 50mm up/down| 50% | 22% 11mm up/down | 25%
Rudder 100% 60mm left/right] 50% 60% 36mm left/right | 25%
Note: 1. This control throws were developed by FMS TEAM for the best performance
of the Yak 54. The small mount of elevator throw on low rate is capable of extreme
aerobatics.
2. At first flight, fly the model in low rate. The first time you use high rates, be sure to fly
at low to medium speeds. High rates, as listed, are only for EXTREME maneuvering. Only
switch to high rate when the plane is flying at slow speed. Never fly at high speed
at full air speed. This plane is very responsive and pilot can easily lose orientation. Get
familiar with the plane first and then try high rate.
3. For take off and landing, low rate in all control surfaces is strongly recommended.
Check the motor rotating direction
1. The motor should rotate counterclockwise
when viewing the plane from the front.

Check the C.G. (Center of Gravity)
Center of Gravity
When balancing your model, adjust the motor battery as necessary so the model is level or
slightly nose down. This the correct balance point for your model. After the first flights, the CG
position can be adjusted for your personal preference.
1. The recommended Center of Gravity (CG) location for your model is (120mm/4.8in) forward from
the leading edge of the main wing (as shown) with the battery pack installed. Mark the location of the
CG on top of the wing.
2. When balancing your model, support the plane at the marks made on the bottom of the
main wing with your fingers or a commercially available balancing stand. This is the correct
balance point for your model. Make sure the model is assembled and ready for flight before
balancing.
Caution: Do not connect the battery to the ESC while balancing the plane.

Before the model flying }
Find a suitable flying site
Find a flying site clear of buildings, trees, power lines and other obstructions. Until you
know how much area will be required and have mastered flying your plane in confined
spaces, choose a site which is at least the size of two to three football fields — a flying
field specifically for R/C planes is best. Never fly near people— especially children who
can wander unpredictably.
Perform the range check of your plane
As a precaution, an operational ground range test should be performed before the
first flight each time you go out. Performing a range test is a good way to detect
problems that could cause loss of control such as low batteries, defective or
damaged radio components, or radio interference. This usually requires an
assistant and should be done at the actual flying site you will be using.
First turn on the transmitter, then install a fully-charged battery into the fuselage.
Connect the battery and install the hatch.
Remember, use care not to bump the throttle stick, otherwise, the propeller / fan
will turn and possibly cause damage or injury.
Note: Please refer to your Transmitter Manual that came with your radio control
system to perform a ground range check. If the controls are not working correctly
or if anything seems wrong, do not fly the model until you correct the problem.
Make certain all the servo wires are securely connected to the receiver and the
transmitter batteries have a good connection.
Monitor your flight time
Monitor and limit your flight time using a timer (such as one on a wrist watch or in your
transmitter if available). When the batteries are getting low you will usually notice a
performance drop before the ESC cuts off motor power, so when the plane starts flying
slower you should land. Often (but not always) power can be briefly restored after the
motor cuts off by holding the throttle stick all the way down for a few seconds.
To avoid an unexpected dead-stick landing on your first flight, set your timer to a
conservative 4 minutes. When your alarm sounds you should land right away.

Flying course |
Take off
While applying power slowly steer to keep the model straight, the model should accelerate
quickly. As the model gains flight speed, you will want to climb at a steady and even rate.
The Yak 54 will climb out at a nice angle of attack (AOA).
Flying
Always choose a wide-open space for flying your plane. ltis ideal foryou to fly at a
sanctioned flying field. 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. Consult
laws and ordinances before choosing a location to fly your aircraft. After takeoff, gain some
altitude. Climb to a safe altitude and begin to trim the model till it's tracks well through all
aspects of flight, including high speed passes, inverted flight, loops, and point rolls.
Landing
Land the model when you hear the motor pulsing (LVC) or if you notice a reduction in
power. If using a transmitter with a timer, set the timer so you have enough flight time to
make several landing approaches.
Recharge the battery and repair the model as needed. The model's three point landing gear
allows the model to land on hard surfaces. Align model directly into the wind and fly down to
the ground. Fly the airplane down to the ground using 1/4-1/3 throttle to keep enough energy
for proper flare. Before the model touches down, always fully decrease the throttle to avoid
damaging the propeller or other components. The key to a great landing is to manage the power
and elevator all the way to the ground and set down lightly on the main landing gear. After a
few flights you will find the model can be set down lightly on the mains and you can hold the
nose wheel off balancing the model on the mains till it slows and gently settles the nose.
Maintenance
Repairs to the foam should be made with foam safe adhesives such as hot glue, foam
safe CA, and 5 min epoxy. When parts are not repairable, see the Spare Parts List for
ordering by item number.
Always check to make sure all screws on the aircraft are tightened. Pay special attention
to make sure the bullet of the rotor adaptor is firmly in place before every flight.
