Please ensure there is no heat-emission ,curve ,transformation,impale and damage
before charging. It is suitable for charging 3S 11.1V and 2S 7.4V Li-ion batteries and
Li-po batteries.
1)
2)Connect the charger wire.
3)Take the battery from the battery bay in the airframe, connect the balance joint of
the battery with the 3S charging port on the charger.
4)It is charging when the indication LED become red. If the LED turn green,the battery
is full charged.
5)Disconnect the batter y with the charger when finished charging.
6)The time to charge the battery full is 60 minutes.
(Caution: Only the designated Charger can be allowed to charge for HMX280 battery.
The use of other charger may cause the injury and damage to the people and property.)
Connect the charger to 220V AC power.

3S port on the charger.
Connect the power wire of the charger
at the back of the charger.
Plug the other side of the power wire
into the power socket, there will be on
three red LED lights. It is the status of
charging.
Put the land gear on the groove of
the airframe, please make left to the
left side, right to the right side
Make the antenna pass through the
landing gear and fasten the copper
bush in the inner side.
When finish the charging,
the LED lights turn green. Take out the
battery, then you can enjoy the flight.
Low-voltage Protection has set in HMX280 system. The
default parameters are as following.
Class 1 Low-voltage Protection:10.5V-10.8V When the
voltage of the battery reach in this range, the red rear
decoration lights are flashing slowly,which is reminding
the low voltage.
Class 2 Low-voltage Protection: 9.6V-9.8V When the
voltage of the battery reach in this range, the quadcopter
will land slowly in the position flying. Please change the
battery or charge for the battery.
（REMINDER: Please fly with the battery correctly. Overcharging or over-discharging
the battery will cut down its ser vice life.）

9.2 Practice Flips:
HMX280 can do excited stunt actions, such as forward and backward, rolling right
and left:
1) Find a spacious ground with soft grass to practice.
2) Select ( )
3) It is advised the beginners increase the ser vo distance of ELEV and AILE of the
transmitter to 100%-110%. It can be adjusted according to personal skill. The
default setting is 100%
4) It is a must to practice with the throttle of the transmitter. When the HMX280
quadcopter change from normal flight to stunt flight ,the throttle stick needs
to pull down slowly. When the model exchanges from stunt flight to normal,
the throttle stick needs to pull up accordingly. Please adjust it according to
personal skill.
