Batteries & Charging
Li-Po Battery
USB Charger
The quadcopter’s Lithium-Polymer battery must be charged before the unit can be
flown. Before charging, be sure the quadcopter and remote control are powered off.
Failure to do so may result in injury.
Step 1
To charge the battery, disconnect the
plugs between the battery and the
receiver board on the underside of the
quadcopter, then gently slide the battery
out of its tray.
Be sure to pull on the connector plugs
only, pulling on the wires may result in
damage to the plugs or wires.
Step 2
Connect the battery plug to the matching
plug on the included USB charger, then
connect the USB charger to a USB power
source, such as a powered on computer
or USB power adapter (recommended,
not included).
The red light in the plug of the USB
charging cable will indicate battery
charge status (see table below).
When the battery is fully charged, re-
install the battery in its tray and connect
the plug to the receiver board.

Pre-Flight Calibration
Quadcopter/Remote Link
Before flying, the quadcopter and the remote must be linked together, and the
gyroscopes on the quadcopter must be allowed to calibrate to ensure smooth and
level flight.
Begin with the quadcopter and remote powered off.
Step 1 - Power ON & Connect
Connect the battery to the quadcopter, place the quadcopter on a flat surface, and turn
on the remote. This will calibrate the gyroscopes in the quadcopter and connect it to
the remote.
YOU MUST PERFORM THIS ACTION QUICKLY FOR IT TO TAKE EFFECT.
When the receiver light at the front of the styrofoam body begins slowly blinking red
and blue, and the Power/Status indicator on the remote is red, the quadcopter and
remote are successfully calibrated and linked.
Step 2 - Take O
Add light throttle until the quadcopter is in the air. If there are any problems, perform
these steps again until a stable hover is achieved. If there are no problems, you may
start flying at will.
Attempt a stable hover, low to the ground.
• Use Left Control Stick and add
light throttle.

Customer Support: 1-888-999-4215
11
Countering Drift & Setting Trim
Even after the quadcopter is calibrated, it may show a tendency to drift while airborne.
Adjusting the trim will counter this effect and allow the unit to hover in place. Adjust
the trim while flying as controlled and low to the ground as possible.
Remember, the red propeller blades indicate the front of the quadcopter.
If the trim adjustments do not seem to be helping, or seem to be making the problem
worse, press the Reset button to the right of the Left Control Stick, to reset the trim
to factory default settings and try again.

Tips for Safe Operation
• Only fly in large, open spaces, such as a field or a very large indoor area, free of
obstacles like power lines, trees, ceiling fans, etc.
• When flying indoors, avoid walls and ceilings, as the quadcopter will be drawn
towards them if closer than 2 to 3 feet.
• Stand behind the quadcopter when first taking off, so that you and the quadcopter
are facing the same “forward” direction. This will make it easier to know which
direction the unit is flying. Also, remember that the red colored propellers indicate
the front of the quadcopter.
• Practice basic flight operations like take off, hovering, and landing.
• Flying inside and at low speed, low to the ground will reduce the chance of
turbulence that can negatively affect the stable flight of the quadcopter.
• Novice pilots should move the controls slowly and deliberately, using one control at
a time, to get used to the quadcopter’s flying characteristics. Next try combining the
pitch and roll controls (forward/backward and left/right on the Right Control Stick)
to fly the quadcopter like the way an airplane flies. After mastering this, try the
yaw controls (left/right on the left thumbstick) to spin the quadcopter in place and
perform more complex flights.
• When you crash, throttle down the engines IMMEDIATELY to reduce the chance of
permanent damage to the quadcopter and other objects.
• If anything obstructs the propellers for any reason, throttle down IMMEDIATELY and
safely clear the obstruction.
Flight Control Sensitivity
The quadcopter has three settings for the responsiveness of the flight controls: 30%,
60%, and 100%. The higher settings allow faster and more precise control inputs. It
is recommended to start with the lowest setting, and as you become more skilled at
flying, increase the sensitivity as you see fit.
• 30%: Intended for novice pilots. Gives a smooth, more relaxed control feel.
• 60%: Intended for advanced pilots. The quadcopter will move and respond much
faster to all control inputs.
• 100% (Stunt Mode): The Right Control Stick will perform a flip in any direction, but
loses the ability to change pitch and roll. Use with care.
Flying & Tips

14
Before attempting any stunts, be sure that there is ample clear space around the
quadcopter, ideally 9 to 10 ft in every direction. It is not recommended to attempt to
stunt around or through any obstacles, as this may result in unintended damage.
There are two ways to perform aerial stunts:
• Press the Stunt button (Right Trigger) to perform a forward flip.
• Set the Flight Sensitivity Control to 100% and use the Right Control Stick to
perform a flip in any direction. The Stunt button does not need to be used in this
case, though it will still function. Note that in this setting, the Right Control Stick will
only perform stunts, and will not adjust the pitch or roll of the quadcopter. Use this
mode with care to avoid damage.
• Press Stunt Button for forward flip.
OR
• Use Right Control Stick with Flight
Control Sensitivity set to 100%.

Using the Camera
This unit is equipped with an on board camera and SD memory card that allows you to
document your flights and view them later. The camera will record stills and video as
JPEG and AVI files. The video files (AVI) can be viewed on a computer with any common
video playing software, like Quicktime or Windows Media Player.
To take video during your flight, press the Left Trigger on the remote control to
begin recording. When the camera is recording video the power/status indicator will
turn green.
To take still shots during your flight, press the Photo button to the right of the Left
Control Stick. The power/status indicator will flash green when it will takes a photo.
Press & hold the Photo button for a 3 photo burst.
When the light on the unit is flashing blue, the SD card’s memory is full and will need
to be downloaded to a computer, and the card formatted, before it can be used again.
The SD card is stored in a slot on the rear of the camera/battery housing. To remove
the SD card, lightly push against it until it springs partially out of its slot, then pull the
card out. Use the included USB/SD card reader to connect to your computer.
After you’ve connected and opened the SD Card file folder (”NO NAME” drive), open the
“DCIM” folder, then “100DSCIM”. You should be able to see and play any of the AVI video
files on the card.
NOTE:
• The video camera does not record sound.
• Proper orientation of the SD Card in the slot (see figure on next page).
• You can format the SD card at any time without worry, the camera will automatically
re-create the DCIM and 100DSCIM file folders.

Troubleshooting

18
Body Repair
The styrofoam shell is designed to absorb
damage from crashes and impacts, but in
doing so it can develop cracks and tears
over time. The easiest way to repair the
shell is to use any kind of light, clear tape
to reconnect and seal the crack.
Rotor Replacement
The quadcopter comes with 4
replacement rotors, to be used if the
originals are broken or badly damaged.
To replace a rotor, use a small Phillips
head screwdriver and remove the screw
connecting the rotor to the electric motor
shaft. Remove the damaged rotor and
replace with a new one, then screw it
back into place on the motor shaft.
REMINDER: It is extremely important
to use the correct rotor (A or B) for
replacement. Using the incorrect rotor
will cause the quadcopter’s flight to
be erratic and impossible to control.
The marking can be seen on the top of
the rotor.
In the event that the quadcopter absorbs light damage that renders flight difficult,
but not impossible, the following repairs are easy to perform and should get the
quadcopter back to a flyable condition.
REMINDER: Pilots are responsible for any damage caused by improper use.
