FLIGHT ADJUSTMENT AND SETTING

PLEASE PRACTICE SIMULATED FLIGHT BEFORE ACTUAL FLYING

Before you are familiar with the unit, please don't pilot it . Read the instruction carefully to get
familiar with the direction controls.
1. Checking that propellers are securely attached to the motors. Pull the throttle down to prevent takeoff.
2. Place quadcopter in a clear open field and point the tail towards yourself.
3. Practice operating the control sticks (as shown below), and repeat practicing "Throttle
high/low", " Left/right ", "Forward/backward", and "bank left/right".
4.Strong impacts can jam the motors, using a long flat nose plier to unjam to rotor.
5.The simulation flight practice is very important, please keep practicing until you are comfortable with the controls.

STEP 1
Direction
Insert the battery into the quadcopter and connect the
plug. The two indicators will begin flashing. Place the
quadcopter on a flat surface.
Important: Be sure the surface is flat and level. The
quadcopter needs to calibrate it's orientation.
FLIGHT ADJUSTMENT AND NOTICE FOR BEGINN
CAUTION
STEP 2
Check if the screws and blades are firmly tightened
Check if the transmitter and helicopter are fully charged.

same time. At this time the indicator light of the aircraf t
flashes and then loosens the remote control, and the
indicator light is always on and the calibration is complete.
Make sure that no people or obstructions are in the vicinity.
You must first practice hovering to fly safely, this is a basic
flight action(meaning keep the helicopter in mid air in a fixed position)
WARNING
Please stand approximately 6ft diagonally behind the helicopter.
When not in use for a long time, please take out the remote
control batter y and keep it properly.
Note: If the remote control batter y is not removed, the long
storage will cause the leakage of the batter y and damage
the remote control device.
1. The throttle is on the left hand, push the throttle a little up to raise the copter to
your line of sight then pull down a little to let the quadcopter slowly down to the
floor. Repeat until you can easily and quickly control the altitude.
2.Hovering flight practic: Raise the quadcopter to a certain height then hover at
that altitude.
3.Try increasing and decreasing the altitude quickly this time while still
maintaining control.
1. Use the right stick to practice moving forward and backwards.
2. Use the left and right stick to practice turns and banking.
1.On/off
(1)On(After put on the battery, R/C is in sleep model,indicator extinguish when off)
Short Press the ON/OFF, the remote control enters the normal mode of work, the buzzer is short
sound one beeping, and the power indicator is fading.
Speed (2)Power off: long press the ON/OFF, the buzzer is short sound two beeping, the power indicator
is out and the remote control is off.
2.Tur ning
When the remote control and the aircraft are pairing the code, move the turning rocker to left and

right,the aircraft will turn left and right.
3.Forward and backward
When the remote control and the aircraft are pairing the code, move the rocker to forward and
backward, the aircraft will fly forward and backward.
The direction rocker
4.Left and right
When the remote control and the aircraft are pairing the code, move the rocker to left and
right,the aircraft will fly left and right.
5.Fine-tuning function
Left and right fine-tuning
The aircraft can be stabilized by adjusting the direction of the aircraft, in the opposite direction of
flight.
6.Headless mode
Front and back fine-tuning Short press the button to enter headless mode. The vehicle's flying direction will be the same as
the demand of controller,no matter where the head is .
7.Stunt
Long press the button for stunt .The beeper will keep. ringing.
8.Speed
Short press the button to adjust the speed. There are three speed levels.You will hear a beep
sound while adjusting . Beep one for level 1 ,beep two for level 2, beep three for level 3. The
higher the level ,the faster the speed.
9.One key take off and one key landing
In the fixed high mode,after press the one key take off and one key landing buttons,
automatically aircraft up to one meter from the ground level hover, trigger buttons again, aircraft
flying will fall to the ground stops automatically
10.One key to retur n
Short press the button for one key to return . Press again to finish return .
11.Calibration
(1) if the aircraft is drifting to one side during takeoff, it can be calibrated to make the flight more
stable
(2)calibration method: the aircraft is placed on the horizontal surface, and the two rocker of the
remote control is pushed to the lower right corner, when observed the indicator light flashes on
the aircraft, release the remote control rocker, indicating that it has been calibrated.
(note: the aircraft should be kept at the horizontal surface. During calibration, the aircraft will not
be able to riot . After the calibration is completed, the indicator light will stop flash quickly).
12：Low voltage war ning:
When the battery is lower than 2.5V of the remote control， the power light will flicker and alarm
prompt to change the battery.
when the aircraft into the low voltage alarm, the buzzer will send a didi alarm of the remote
control , indicating that the aircraft needs to stop flying
Throttle
E RS
Slowly raise the throttle stick and observe just as the helicopter lifts off the ground if it
leans in a direction. You can use the trim to correct this action.
1. Adjustment of Left/Right trim
Just before the quadcopter lifts-off, the nose leans left/right.
When it leans right adjust the trim to the left side.
When it leans left adjust the trim to the right side.
2. Adjustment of Forwards/Backwards trim
Just before the quadcopter lifts-off, the nose leans forward/backwards.
When it leans forwards adjust the trim down.
When it leans backwards adjust the trim up.
3. Adjustment of Roll trim
Just before the quadcopter lifts-off, the body rolls left/right.
When it rolls right adjust the trim to the left side.
When it rolls left adjust the trim to the right side.
