As the user of this product, you are solely responsible for operating in a manner that does not endanger yourself and others or
result in damage to the product or the property of others. This model is controlled by a radio signal subject to interference from
many sources outside your control. This interference can cause momentary loss of control so it is advisable to always keep a
safe distance in all directions around your model, as this margin will help avoid collisions or injury.
Age Recommendation: Not for children under 14 years. This is not a toy.
·Never operate your model with low transmitter batteries.
·Always operate your model in an open area away from cars, traffic or people.
·Avoid operating your model in the street where injury or damage can occur.
·Never operate the model in populated areas for any reason.
·Carefully follow the directions and warnings for this and any optional support equipment you use (chargers,rechargeable
battery packs, etc.)
·Keep all chemicals, small parts and anything electrical out of the reach of children.
·Moisture causes damage to electronics. Avoid water exposure to all equipment not specifically designed and protected for this

·Never lick or any place of any your model in your mouth as it could cause serious injury or even death.
Lithium Polymer (Li-Po) Battery Warning
CAUTION: Always follow the manufacturer’s instructions for safe use and disposal of batteries. Fire, property
damage, or serious injury can result from the mishandling of Li-Po batteries.
By handling, charging or using a 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!
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 40-120F. Do not store the 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 to charge Li-Po Batteries. Failure to charge the battery with a Li-Po compatible charger
may cause fire resulting in personal injury and property damage.
Never discharge Li-Po Cells below 3V.
Never leave charging batteries unattended.
Never charge damaged batteries.
Charging the Flight Battery Warning
Use a battery charger that is designed to safely charge the Li-Po Battery. Read the charger instructions care
fully before use. When charging the battery, make certain the battery is on a heat resistant surface. It is also highly
recommended to place the Li-Po Battery inside a fire resistant charging bag readily available at hobby shops or
online.

Battery installation
1. Pull back on the release tab and remove the battery hatch.
2. Apply hook tape to the cable end of the battery.
3. Make sure the battery is secured using hook tape.
Note: batteries from different manufacturers will vary in
weight and size, it is therefore important to check the center
of gravity of the aircraft before every flight.

ESC
and
model information
1. 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
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.
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.
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 3300mAh-4000mAh 35C Li-Po battery. If using another battery,
4.
the battery must be at least a 14.8V 3300mAh-4000mAh 35C battery. Your battery should be approximately the same capacity,
dimension and weight as the 14.8V 3300mAh-4000mAh 35C 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.
Bank left
Please refer to your transmitter manual for proper operation.
CAUTION: To prevent personal injury, DO NOT install the propel-
ler assembly onto the motor shaft while testing the control surfac-
es. 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.

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(75-85mm) 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.
