Ch arging the Flight Battery
The Battery Charger included(depending on the type of kit you purchased) with your aircraft 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 (depending on the type of kit purchased)
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
40-12QOF. Do not store the battery or the 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
RTF kits come with a DC balancing charger. You must charge the battery with
a Li-Po specific charger only (such as the included BC-3S10 DC charger). 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.
BC-3S10 Balance Charger
To correctly use the charger, please read the instructions before use.

mA
Using Steps:
1. Connect the charger to adapter with enough voltage and wattage, then the Power LED will turn on;
2. Connect 2S/3S battery pack to the corresponding balance port (Do not connect two battery
packs at the same time), then the Charge LED will flicker (1 Hz) and start charging.
3. When the Charge LED stops flickering, charging is complete, and the batteries can be unplugged.
Charging Function Description
1. If total voltage of the installed battery pack is higher than 4.18V, charging will not start and the charge
LED will shine.
2. If the voltage of one or battery cells is lower than O. 7V, charging will not start. If the voltage of the
first cell of a 3S battery pack is lower than O.
7V, the charger will charge the battery pack as if it was a
2S battery pack.
3. If the voltage of one or more battery cells is lower than 2.8V, the charger will activate the battery
pack with a small current. If the voltage can't be increased above 2.8V after half an hour, the charger
will read the battery pack as bad. The charge LED will then flicker rapidly (0.5Hz}, and charging will
stop.
Self Checking Function
1. Charger will perform a self test before each charge. The charge LED will rapidly flicker
(O.SHz) if the charging function is abnormal;
2. Accuracy checking Function: Connect a fully charged 3S battery pack (all voltage at least 4.2V),
the charge LED will flicker twice then shine always. This means that the accuracy is normal.

Protection Function
1. Reverse connection protection of input
2. Reverse connection protection of output
3. Short circuit protection of output
4. Over voltage protection of output
Troubleshooting
Charging the Flight Battery
J
1. Power LED does not shine-Adapter isn't connected correctly. Please check the polarity
and reconnect adapter.
2. Charging abruptly stops and tries to restart constantly during charging- Output power
of the adapter is not sufficient, please replace the adapter.
3. Charge LED does not shine- Reconnect the battery pack; Check the voltage of batteries.
4. Charge LED rapidly flickers -Battery is bad or charging function is abnormal. Replace
battery or contact technical support.

Low voltage cut off (LVC)
J
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 (available on-line).

Important ESC and model information
1. The ESC included with the WACO has a safe start. If the 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.
2. 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.
3. The motor has an optional brake setting. The ESC comes with the brake switched off
and we recommended that the WACO 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.
4. Battery Selection and Installation. We recommend the 11.1 V 1800mAh 25C(150g/5.3oz)
Li-Po battery. If using another battery, the battery must be at least a 11.1 V 1800mAh 25C
battery. Your battery should be approximately the same capacity, dimension and
weight as the 11.1V1800mAh 25C Li-Po battery to fit in the fuselage without changing
the center of gravity significantly.
5. No beeps from the motor means you need to calibrate the throttle or restore the factory setup
defaults.
How to calibrate the throttle:
1. Power on your Transmitter
2. Set the Throttle stick all the way up to 100%
3. Power up your aircraft.
4. Wait about 2 seconds and you will hear 2 beeps, immediately after the first beep,
bring your throttle stick all the way down to 0%.
5. You will hear a single initializing beep.
6. Power down your Aircraft then Transmitter.
7. Power on your Transmitter first then the Aircraft and you should be all set.
How to restore ESC settings:
Repeat the
How to calibrate setting, but the restoring step holds
more audible tone accounts, please refers to ESC manual to set the ESC, every signal means a
tone in the manual. For example, the mark"* ___ *" means a tone. When you hear the fourth tone
in the restore step, bring your throttle stick all the way down to 0%.
Caution: If you try to weld a new connecter 3.5 Golden plug, XT 60 or a Dean plug. Please refer
to the polarity on your battery and make sure you do not weld the connector pole in reverse, or
the short circuit will ruin your battery and the ESC.

The transmitter and model setup
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 in the OFF position. Make sure both ailerons
deflect up and down (travel) equally. This model tracks well when the left and
right ailerons travel equally in response to the control stick.
1. Move the controls on the transmitter to make sure aircraft control surfaces move in
correct direction. See diagrams below. You may have to reverse the channel.
Refer the Transmitter's Manual.

2. 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.
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 ailerons with the wing root by turning the clevis clockwise and counterclockwise
on the linkage, carefully open the clevis fork and put the clevis pin in the desired hole
of the control horn.
Note: Please secure the clevis with provided piece of tube after the alignment of the
surface is completed.
Adjust the control connector on the servo arm to align the elevator and the rudder well.
Note: Make sure the tail wheel align with the fuselage centerline by adjusting the
connector on the linkage rod.
