Introduction
Precautions and war nings
Please perform this model by following the warnings very closely
Note on Lithium Polymer This is the safty precautions and must be strictly followed.
Lithium Polymer batteries are significantly more volatile than alkaline or Ni-Cd/Ni-MH
batteries generally used in RC applications, which may have better advantages in
weight and capacity but not stable enough. All manufacturer's instructions and
warnings must be followed closely. By handling, charging or using the included
Li-Po battery, you assumeall risks associated with lithium batteries. If you do not
agree with theseconditions, return the complete package of model in unused condition
to the place of purchase immediately.
Do not charge package- attached battery with mismatched transmitter or charger !
Do not charge other batteries with package-attached transmitter or charger
Never charge near or in the area of any flammable or combustible materials
When charging the battery you should always remain in constant observation to monitor the
charging process and react to potential problems that may occur.
If at any time during the charge or discharge process the battery begins to balloon or swell,
discontinue charging or discharging immediately. Quickly and safely disconnect the battery, then
place it in a safe, open area away from flammable materials to observe it for at least 15 minutes.
Do not continue charging a battery that has begun to balloon or swell .Handle the lithium battery safely.
After flight, the Li-Po batteries must be cooled to the ambient temperature before charging.
Do not over-discharge the Li-Po flight battery. Discharging the battery too
low can cause damage to the battery resulting in reduced power, duration
or failure of the battery entirely
Please store the battery in cool ,dry places under 25 degrees Celsius when you are not using it .
Troubleshooting Guide
Please refer to below list to resolve the possible problems during flying .
Other notice and precautions

Hover
When the helicopter is flying to a certain high level, you can try to hover. Push the right hand stick
up and down slightly to make the helicopter go up and down slowly .Please refer to the adjusting methods
in the first part”Take off” to do some slight adjustments to the helicopter. When finished above adjusting ,
the helicopter should keep at a certain high level almost without any throttle input.
Practice more and make yourself to be able to freely control the helicopter
going up and down
Landing
Pull the right hand stick downward slowly to land the helicopter steadily on a plain ground.
Area Flying
When you can successfully fly the helicopter in hover , you can start to learn to
control the helicopter to fly in a certain area.
When the helicopter is lifted to a certain high level, practice controlling the helicopter by joysticks to
go forward, backward, turn left and right .At the early stage of practice, control 2 directions each time ,
you can do multiple directions control when you are experienced .
For professionals Please move on to this level after mastering the basic flying skills
Side fly to left and right in hover
When the helicopter is lifted in a certain high level , move the helicopter to side fly to left and right .
When you go side fly , the throttle will move along. So when doing side fly(or after),
the helicopter might go up and down rapidly .Please do some adjustments immediately
by pushing the throttle to the opposite direction .
Advanced fly mode
When the advanced mode is open, the flying sensitivity will be increased and
the operation will be harder as well . Please do not open the advanced fly mode
before you master the basic flying skills.
After turning on the controller power switch and closing the
protection system, push both buttons at once on the
controller as shown by the right chart. The power indicator
light is blinking ,showing the advanced fly mode is open
(close the mode by pushing again both same buttons at once)

AA Battery
Lithium battery

Installing the flight battery
Install the fully charged battery
in the helicopter by sliding it into
the battery mounting slot with
the exposed metal polarity facing
downward just below the main
gear (the LED on the circuit board
of the helicopter blinks fast)
Close the safety protection system

closed , this model can not receive any other operation instructions.
1.Power on the controller(the power indicator begins blinking)
2.Push the right hand stick from the top to the bottom,controller beeps(power indicator stops blinking)
the LCD on circuit board stops blinking ,this means the safety protection system is closed.
Control test
Although each Blade mSR model is test flown at the factory, it is a good idea to test the
controls prior to the first flight to ensure none of the servos, linkages or parts were
damaged during shipping and handling .This process could prevent crash caused by
mechanical failure to happen and ensures fly safety.
Close the safety protection system.
With the left hand stick pushed up, the right side servo should push the swashplate downward.
With the left hand stick pushed down ,the right side servo should push the swashplate upward.
With the right hand stick pushed to left horizentally, the left side servo should push the swashplate
downward.
With the right hand stick pushed to right , the left side servo should push the swashplate upward.
With the right hand stick pushed up slowly, the propeller starts rotating(but the helicopter remains
on the table), meanwhile push the left hand stick to left, the helicopter will turn to left on the table .
Push the left hand stick to right horizentally, the helicotper will turn to right on the table .
Please make sure everthing is ok before flying the helicopter!
Please contact the manufacturer when any incidents occur.
How to fly Please push the throttle to the bottom immediately when
any incidents occur.
