Quick Start Guide
4.0 Attention before Flying
1) The RUNNER 250 is recomended for pilots, 14 years or older, with RC hobby experience.
2) Only fly the RUNNER 250 in dry weather, with low wind, please do not fly in rain or heavy foggy conditions.
3) Always choose large open fields for flying. Check local LAW and ordinances for legal flying areas.
4) Always keep at least 10 feet distance to the aircraft when armed, to avoid injury from high-speed propellers
on the ground or while flying. Always disarm before handeling the aircraft.
5) Do not fly close to high-voltage power lines, cellphone towers, or radio towers, as these may disrupt
your control signal.
6) ALWAYS check local laws BEFORE flying. NEVER fly over crowds, concerts or sports stadiums.
5.0 Charge the Battery
Insert the power adapter(100-240V 50/60HZ), connect
the output end to the GA005 balance charger, the balance
charger is red LED at this time.
0 Insert the battery charging terminal into 3 Cell DC 11.1V
charger socket.
0 During charging, Red LED is continuously flashing. If
saturated, Red LED becomes solid green lighting.

Attention:
• Place the aircraft in a wide open space, with the rear facing you.
(This position is known as "TAIL IN")
• Put all the function switches to the 0 position, put all trims and dials to the Middle position,
move the throttle to the lowest position, then turn on the Remote Controller.
• A video receiving equipment is needed( such as Goggles glasses, etc. ) to display
an image and OSD information. (Setting method please refer to P15)
• The RUNNER 250 have a low-voltage alarm beeper.
And the OSD give you a visual reference for the remaining battery power.
When voltage reach below 10.8 volts the LEFT red LED lights will flash slowly and the beeper
will sound alarm.
WARNING: Do not hesitate to land when you hear the alarm or see the OSD indicating 10.8 volts.
8.1 Starting the aircraft / Get binding
Turn on the Remote Controller. (Make sure all the
function switches, all trims/knobs and throttle stick
at the lowest position)
0 Put the aircraft to the horizontal place and connect
the aircraft power. (make sure the positive and
negtive connected correctly)
® The red LED light on the left of aircraft flashes slowly
until goes out, indicating that the IMU preheating
is complete and the code binding is successful.
If it issuing the sound of "BB" that it is fail to IMU
preheating. Pls restart the aircraft.

Tips:
•
Do not move the aircraft during start-up.
• ALWAYS unfold the two reciever anteannas to
their correct STRAIGHT UP position before flying.
Do not fly without properly unfolding the antennas.

Be very careful at this point, as pushing the thottle up will start the motors.
You can test by pushing the stick up a little, the motors should start.

Hyper IOC Mode
IOC or Intelli g ent Orientation Control mode means that the aircraft's fli g ht direction is only relative to the
ori g nal take-off point (where you armed the motors). REGARDLESS of the actual aircraft headdin g , in this
mode you can fly past somethin g and pan the aircraft to frame your shot, without havin g to worry what
direction the aircraft is facin g .

Attention:
1) Make sure that the received GPS signal (RIGHT red LED light blinks)
2) IOC is inactive if the RUNNER 250 is less than 10 meter (30 feet) from the original take-off position. (point where you armed the motors)
Fly the RUNNER 250 manually beyond 10 meters using the GPS mode, then activate the IOC mode, the RUNNER 250 will now
fly IOC until you change the mode, you can pan freely for video shots, when you push the stick right or left, the RUNNER 250
will move sideways relative to the original take-off position. Pushing the pitch stick up will push the RUNNER 250 away from
you, pulling the stick back brings the RUNNER 250 back to the starting point. When flying in IOC mode, you can make the
RUNNER 250 return to the starting point simply by pulling the stick toward you.
WARNING: The IOC turns off when the aircraft gets closer than 10meters to the take off point. Be prepared for this, as the
system will switch back to GPS hold mode at that point. This switch can cause confusion if the pilot are not prepared.

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 7.4V/ 11.1V Li-ion or Li-polymer battery pack.
4) GA005 can detect Li-Po battery automatically. GA005 will automatically charge when it finds the voltage of
single cell battery is excessively low. At the same time LED displays as charging status (flash in red).
Control single cell battery voltage at the range of 4.2 ±0.05V to ensure the maximum voltage difference of
single cell in the battery is less than 50 mV.
1) 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. Either the charger or battery may be damaged.
2)
During charging, GA005 should be put in dry and ventilated place and be far away from heat sources and inflammable
and explosive substances.
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 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.
Please change new one in time when the old battery pack 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.
