Aircraft flight is a high risk hobby, whose flight should be kept far away from other people. Mis-assembled or
broken main frame, defective electronic equipment, and/or problematic radio system will lead to unforeseen
accidents such as bodily injury or property damage. The pilot MUST pay attention to the flight safety and
UNDERSTAND his responsibility for accidents caused by his carelessness.
(1)
Far away from obstacles and people
An Aircraft in flight has risk of uncertain flight speed and direction which is
potentially dangerous. When flying, please keep your Aircraft far away from
people, high buildings, high-tension lines, etc, and avoid operating in rain,
storms, thunder and lightening.
(2) Keep away from humidity

as:(1;121
GPS altitude hold system
(5)
Safe operation
Please fly your Aircraft according to your physical status and flight
skills. Fatigue, listlessness and mis-operation will increase the
possibilities of accidental hazard.
(6) Away from highly spinning parts
Please keep pilot, people and object away from the spinning blades
of both main rotor and tail rotor.
(7) Protect from heat
An Aircraft is made from metal, fiber, plastic and electronic components,
etc. Please keep away from heat and sunshine in order to avoid
distortion, even damage, caused by high temperatures.
2.3 Attention before flight
(1) Ensure the battery packs of both transmitter and receiver are fully charged (saturated).
(2) Ensure both the throttle stick and the throttle trim of your transmitter stay at the lowest positions before
operation.
(3) Please strictly obey the order of turn-on and turn-off before operation. When starting your flight, please turn
on your transmitter first, and connect the power cable of your helicopter last.
When finishing your flight, please disconnect the power cable of your helicopter first, and turn off your transmitter
last. An upset in the order of connection may cause your helicopter to loose control. Please cultivate a correct
habit of turn-on and turn-off.
(4) Assure there are solid connections between the power cables of battery pack and motors. Continuous vibrations
in flight may loosen the battery tie-ins.

9.6.2 IOC Definition
In the IOC mode, the quadcopter's forward direction moves by ELEV/AILE stick of the transmitter and only be
relatived by the original RX binding positon. Because the RX reset position determinated the quadcopter's flight
direction in IOC mode. And the flight direction be no relative with the head direction or the radio control direction.
Note:
(1) In Manual mode, the quadcopter's flight direction is same as its head direction.
(2) In IOC mode, the quadcopter's flight direction is same as the RX reset position.
9.6.3 IOC Setup
Turn the FMOD switch to Position "2", the quadcopter enter into IOC mode, in IOC mode, the quadcopter can
move by the ELEV/AILE stick of the transmitter (if RTF, the default switch is FMOD and it is close. For setting,
please ref to radio setting).

11.2 Features of GA005 balance charger
(1) GA005 utilizes microcomputer chips to monitor and control over the whole charging process in a balanced
way with LED indicator to display the charging status at real time.
(2) Connects to an input power supply (DC 15-18V 1000 mA).
(3) GA005 is suitable for 2-3S (7.4V/ 11.1V) Li-ion or Li-polymer battery pack.
(4) Automatically detects 2-3S Lithium battery. GA005 will automatically charge when it finds the voltage of anyone
cell among the LiPo pack is excessively low. At the same time LED displays as charging status (flash in
red). The voltage of anyone cell LiPo is controlled at the level of 4.2 ± 0.05V to ensure the maximum voltage
difference of single cell in the battery is less than 50 mV.

11.6 Matters needing attention
(1) During charging, GA005 should be put in dry and ventilated place and be far away from heat sources and
inflammable and explosive substances.
(2) GA005 is only used to charging a 2S or 3S Li-ion or Li-polymer battery. It is forbidden to simultaneously
charge two or more sets of batteries packs. Either the charger or battery may be damaged.
(3) When charging, the battery should be removed from your helicopter. Never leave the charger unsupervised
during the process of charging in order to avoid risk of accidents.
(4) Never immediately charge your battery as soon as the flight is finished, or when its temperature doesn't cool
down. Otherwise the battery will take a risk in swelling, even catch a fire.
(5) Ensure the correctness of polarity before connecting the battery to charger.
(6) Avoid drop and violence during the process of charging. Drop and violence will result in internal short circuit
of the battery.
(7) For the sake of safety, please use original charging equipment (wall adapter + GA005 balance charger) and
battery pack. Please change new one in time when the old battery is becoming swollen due to long time
usage.
(8) If it is retained in the charger for a long time after saturated, the battery may automatically discharge. When
the charger detects that the voltage of individual cells is lower than the rated voltage, it will re-charge until
saturated. Frequently charging and discharging will shorten the lifetime of your battery.
11.7 Maintenance of battery pack
(1) The battery should be put in dry and ventilated place. The storage temperature of the environment is ranged
from 18°C to 25°C.
(2) Please avoid frequent charging and excessive discharging the battery in order to prolong its life cycle.
(3) It is a must to maintain the battery before long-term storage. That is to charge the battery to the level of 50-
60% saturation.
(4) If the storage term is over 1 month, it is advised to monthly check the voltage of every cell of the battery .
The voltage of every cell should be not less than 3V. Otherwise, please refer to the above article (3).
(5) From the view point of protection, new battery should be motivated before usage. That is to charge and
discharge 3-5 times, but discharge is not less than the level of 70% saturation. This process will make the
battery lifetime longer and voltage more stable.
