Battery and Charging Warnings
The included USB charger has been designed to safely charge the included Li-Po battery.
CAUTION: All instructions and warnings must be followed exactly. Mishandling of Li-Po batteries can result in a fire,
personal injury and/or property damage.
• By handling, charging or using the included Li-Po battery, you assume all risks associated with lithium batteries.
• If at any time the battery begins to balloon or swell, discontinue use immediately. If charging or discharging,
discontinue and disconnect. Continuing to use, charge or discharge a battery that is ballooning or swelling can result
in fire.
• Always store the battery at room temperature in a dry area for best results.
• Always transport or temporarily store the battery in a temperature range of 40–120° F. Do not store the battery
or model in a car or direct sunlight. If stored in a hot car, the battery can be damaged or even catch fire.
• Always charge batteries away from flammable materials.
• Always inspect the battery before charging, monitor the temperature of the battery pack while charging.
• Always disconnect the battery after charging, and let the charger cool between charges.
• ONLY USE A CHARGER SPECIFICALLY DESIGNED TO CHARGE LI-PO BATTERIES. Failure to charge the battery
with a compatible charger may cause a fire resulting in personal injury and / or property damage.
• Never discharge Li-Po cells to below 3.0V under load.
• Never cover warning labels with hook and loop strips.
• Never leave charging batteries unattended.
• Never charge batteries outside recommended levels.
• Never charge damaged batteries.
• Never attempt to dismantle or alter the charger.
• Never allow minors to charge battery packs.
• Never charge batteries in extremely hot or cold places (recommended between 40–120° F or 5–49° C) or place
in direct sunlight.

Installing the Battery
The transmitter comes pre-bound to the aircraft, so binding should not be necessary.
Keep the aircraft and transmitter away from large metal objects, wireless sources or other transmitters while
installing the battery.
CAUTION:
● Before flying, power on the transmitter first, then power on the plane. After flying, power off the plane
first, then power off the transmitter.
● Always disconnect the Li-Po battery from the aircraft receiver when not flying to avoid over-discharging
the battery. Batteries discharged to a voltage lower than the lowest approved voltage may become damaged,
resulting in loss of performance and potential fire when batteries are charged.
● Always keep hands away from the propeller. When armed, the motor will turn the propeller in response
to any throttle movement.
Charging the Battery
CAUTION: Once charging is complete, immediately remove the battery. Never leave a battery connected to the charger.
1. Insert the charger into a USB port.
2. Properly connect the battery to the charger.
3. Charging a fully discharged (not over-discharged) 380 mAh battery takes approximately 30-40 mins.
4. The LED Solid Red means charging, the LED off means charging is complete.

Transmitter Batteries Installation
Remove the battery cover. Install the four batteries (noting proper polarity) and reinstall the battery cover.
Transmitter Low Battery Alarm
When the battery voltage drops too low, an alarm sounds (D.D.D). The batteries must be replaced immediately.
If this happens while flying, land your aircraft as soon and as safely as possible.

When aircraft voltage is less than 3.3V, the transmitter keeps
beeping “DDD.DDD.DDD”, you can still fly for another 3-4 minutes, which will
give you the time to land the plane before lost the power.

Flying Tips
• Consult local laws and ordinances before choosing a location to fly your aircraft.
• The built-in Flight Controller System is designed as flight assistance, not an autopilot. The pilot is always in
control and required to fly the aircraft at all times.
• Start in Beginner mode. As you learn and become more confident, change modes to advance your flying skills.
• Always make deliberate and steady control stick movements for smooth control of your aircraft.
• Fly your aircraft outside in no greater than light winds.
• For indoor flight, fly the aircraft inside in a large gymnasium.
• Keep your aircraft in plain sight and up wind.
• Always avoid flying near houses, trees, wires and buildings.
• Always avoid flying in areas where there are many people, such as busy parks, schoolyards or soccer fields.

Different Flight Modes
Beginner Mode (with self leveling): Pitch (nose up and down) and Roll (wing tips up and down) angles are limited
to help you keep the aircraft airborne. Release both sticks for self-leveling.
Middle Mode: The pilot is only prevented from entering extreme flight conditions.
Advanced Mode: Unlimited Flight Capability
Set “One Key Return Home”
Place the plane on the ground, pointing to the front of the flying field, power on the transmitter and then the
plane, make sure the binding is finished, then press “RETURN HOME ”button, the rudder will move then back to
neutral, means the plane already remember the take-off direction and the setting for “One Key Return Home”
finished. If you feel you have lost control or want the plane fly back (this function works only in Beginner mode or
Middle mode, not in Advanced mode), just press the “RETURN HOME” button, then the plane will turn around and
fly back toward to the take-off direction, when it closer to the take-off point, you should take over the control
again, or it will keep flying toward the same direction (far away from you). It will be very easy to take over the
control again by just moving any of the joysticks.
Note: This function will only makes the plane fly backward against the take-off direction, so you can use
this function when the plane is in front of your take-off point, if the plane already goes to the back of your take-off
point, when you press the “RETURN HOME” button, it will keep flying to the same direction (far away from you).

Binding Procedure
Power on the plane, the LED in the FC (Flight Controller) will flash, then power on the transmitter, if the LED in the
FC change to solid, means the binding was finished. If the LED in the FC still flashing, means the binding failed,
please do the above mentioned procedure again. Note: If the throttle stick is not in the lowest position (0 position)
when you binding, you have to move the throttle sticker back to lowest position then move the throttle sticker again
and you can have the throttle working.

Take off
Hand Launch
Use the Beginner mode for takeoff in first flights. Get help to hand launch your aircraft so you can concentrate
on flying. If you must hand launch the aircraft alone, hold the Aircraft in your dominant hand and the transmitter
in your other hand.

Ground Launch
• Take off from a hard and level runway.
• Use the rudder control to keep the aircraft rolling straight.
• Turn the aircraft only after it is high off the ground.
Gently pull back on the elevator
stick to lift off of the ground.

Flying
In Beginner mode, when properly trimmed, your aircraft will climb at full throttle without use of the elevator stick.
• Try to fly the first few times for about 6 minutes to know more about the flying capability.
• If the motor pulses, land the aircraft immediately and recharge the flight battery.
• Flying with the nose pointed toward you is one of the hardest things to do when learning to fly. To practice
piloting the aircraft, try flying in large circles high off the ground.

Wind (0–8 km/h)
Landing
Fly to your runway, keeping the aircraft pointed into the wind and the wings level. Bring the aircraft down by
lowering the throttle to 25%. Near the ground, fully lower the throttle and pull back on the steering stick.
CAUTION: Never catch a flying aircraft in your hands. Doing so could cause personal injury and damage
to the aircraft.
After Flying
1. Lower the throttle stick completely and do not move the steering stick. Wait at least 5 seconds.
2. Disconnect and remove the battery from the aircraft. Keep hands away from the propeller.
3. Power off the transmitter.
4. Fully charge the aircraft battery.
5. Remove the battery after charging is complete.
NOTICE: When you are finished flying, never leave the aircraft in direct sunlight or in a hot, enclosed area such
as a car. Doing so can damage the foam.
NOTICE: Always disconnect the battery from the aircraft before powering off the transmitter or injury and
damage may result.
REPAIRS
Repair this aircraft using foam-compatible CA (cyanoacrylate adhesive) glue or clear tape.
Only use foam-compatible CA glue as other types of glue can damage the foam.
NOTICE: Use of foam-compatible CA accelerant on your aircraft can damage paint. DO NOT handle the aircraft
until the accelerant fully dries.
