Important ESC and model information
The ESC included with the model has a safe start. If the motor battery is connected to the ESC and the throttle stick is not in
1.
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 detected the cells of the battery. The count of the beeps equals 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
2.
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 brake switched off and we recommend that the model be flown
3.
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 2200mAh 25c Li-Po battery. If using another battery, the battery
4.
must be at least a 14.8V 2200mAh 25c battery. Your battery should be approximately the same capacity, dimension and weight
as the 14.8V 2200mAh 25c Li-Po battery to fit the fuselage without changing the center of gravity significantly.

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 arm the 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 is 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.
Move the controls on the transmitter to make sure the aircraft
control surface moves correctly. See diagrams right.

Check the C.G. (Center of gravity)
When balancing your model, adjust the battery as necessary
so the model is level or slightly nose down. This is the correct
balance point for your model. After the first flight, the CG
position can be adjusted for your personal preference.
1. The recommended Center of Gravity (CG) location for your
model is(60-70mm) 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.

Before flying the model
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 for 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.
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. It will
climb out at a nice angle of attack (AOA).
Flying
Always choose a wide-open space for flying your plane. It is
ideal for you 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 height before trying
technical manoeuvres, including high speed passes, inverted
flight, loops, and point rolls.
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 on a
wristwatch 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.
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.
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
lightlyon the mains and you can hold the nose wheel off
balancing themodel on the mains until 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 5min 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 spinner is
firmly in place before every flight.

Programmable Items (The option written in bold font is the default setting)
1. Brake Setting:Enabled / Disabled
2. Battery Type:Lipo / NiMH
3. Low Voltage Protection Mode(Cut-Off Mode):Soft Cut-Off (Gradually reduce the output power) /Cut-Off
(Immediately stop the output power).
4. Low Voltage Protection Threshold(Cut-Off Threshold):Low / Medium / High
1) For lithium battery, the battery cell number is calculated automatically. Low / medium / high cutoff voltage for
each cell is 2.85V/3.15V/3.3V. For example: For a 3S Lipo, when "Medium" cutoff threshold is set, the cut-off
voltage will be:3.15*3=9.45V.
2) For NiMH battery, low / medium / high cutoff voltages are 0%/50%/65% of the startup voltage (i.e. the initial
voltage of battery pack), and 0% means the low voltage cut-off function is disabled. For example: For a 6 cells
NiMH battery, fully charged voltage is 1.44*6=8.64V, when "Medium"cut-off threshold is set, the cut-off voltage
a) Normal mode is suitable for fixed-wing aircraft. Soft or Super-soft modes are suitable for helicopters. The
initial acceleration of the Soft and Super-Soft modes are slower, it takes 1.5 second for Soft startup or 3 seconds
for Super-Soft startup from initial throttle advance to full throttle. If the throttle is completely closed (throttle stick
moved to bottom position) and opened again (throttle stick moved to top position) within 3 seconds after the first
startup, the re-startup will be temporarily changed to normal mode to get rid of the chance of a crash caused by
slow throttle response. This special design is suitable for aerobatic flight when quick throttle response is needed.
6. Timing:Low / Medium / High,( 3.75°/15°/26.25°) Usually, low timing is suitable for most motors. To get higher
speed, High timing value can be chosen.

Begin To Use Your New ESC
IMPORTANT! Because different transmitter has different throttle range, please calibrate throttle range
before flying.
Throttle range setting (Throttle range should be reset whenever a new transmitter is being used)
1.Switch on the transmi t ter, move throttle stick to the top position.
2.Connect battery pack to the ESC, and wait for about 2 seconds.
3.The "Beep-Beep-" tone should be emitted, means the top point of throttle range has been confirmed.
4.Move throttle stick to the bottom position, several "beep-" tones should be emitted to present the amount of
battery cells.
5.A long "Beep-" tone should be emitted, means the lowest point of throttle range has been correctly confirmed.
Normal startup procedure
1.Move throttle stick to bottom position and then switch on transmitter.
2Connect battery pack to ESC, special tone like "♪ 123" means power supply is OK.
3.Several "beep-" tones should be emitted to present the amount of lithium battery cells.
4.When self-test is finished, a long"beep-----" tone should be emitted.
5.Move throttle stick upwards to go flying.
EN
Protection Function
1. Start up failure protection: If the motor fails to start within 2 seconds of throttle application, the ESC will cut-off
the output power. In this case, the throttle stick MUST be moved to the bottom again to restart the motor. (Such a
situation happens in the following cases: The connection between ESC and motor is not reliable, the propeller or
the motor is blocked, the gearbox is damaged, etc.)
2. Over-heat protection: When the temperature of the ESC is over about 110 Celsius degrees, the ESC will reduce
the output power.
3.Throttle signal loss protection: The ESC will reduce the output power if throttle signal is lost for 1 second, further
loss for 2 seconds will cause the output to be cut-off completely.
