ation. Performing a flight and an aerial appli-
cation in clothing that is not appropriate for
the task could cause loss of visibility, maneu-
vering error, or cause your foot to slip, result-
ing in unexpected accidents. Furthermore, it
could harm your health through exposure to
agricultural chemicals.
WWARNING
A minimum of three people is required for an
aerial application: a signaler who has been
briefed on the aerial application procedure,
an assistant who readies, mixes, and sup-
plies agricultural chemicals, and an operator.
Beware that an understaffed operation could
lead to an accident.

The operation of an unmanned helicopter
involves considerable mental fatigue. The
operator should not fly the helicopter contin-
uously for more than one hour, but should
take a rest every hour. Prolonged continuous
flight operation could cause the operator to
lose concentration and could lead to an acci-
dent.
Do not fly the helicopter after drinking alco-
hol or taking a cold medicine, or if you are in
poor physical condition. Flying the helicopter
in poor physical condition could cause loss
of concentration, and could lead to an acci-
dent.

With the helicopter’s main switch turned OFF,
turn the transmitter’s power ON, and inspect the
following items.
Check that the output lamp and the battery
monitor lamp are illuminated green.
Check the number of times the buzzer sounds
to indicate the battery state-of-charge.

The battery monitor lamp works in unison with
the buzzer sound that indicates the battery state-
of-charge.
When the battery gets low, the battery monitor
lamp will start flashing red. When the battery
gets even lower, the lamp will stay lit.
At this point, working in unison with the transmit-
ter’s monitor lamp, the warning lamp flashes red
to warn the operator. When this happens, it
means that the battery is practically drained.
Therefore, replace it with a fully charged battery.
* On the FAZER, the red lamp of the helicopter warning lamp flashes to inform the operator that the transmit-
ter’s battery state-of-charge is low during flight. (Refer to page 3-12.)
Beep beep beep beep (4 times) The battery is fully

The failsafe function has
been tripped due to a failure
in receiving operating radio
signals.
When the helicopter enters the
failsafe mode, it will descend
automatically.
See the page regarding the fail-
safe mode.

If the radiowaves for operating the helicopter does not reach the helicopter due to some kind of failure, the
helicopter becomes inoperable, which is very dangerous. When a radiowave interference occurs, the safe
function will cause the red and yellow warning lamps to rapidly illuminate alternately, and automatically effect
the controls (operations) described in the next page and thereafter. Familiarize yourself with this function thor-
oughly, and take appropriate actions.
Safe Functions During Failsafe Mode
(Radio Signal Interference)
During radio signal interference, never
approach the helicopter until the main rotor
stops rotating completely, and the engine
has come to a complete stop. If there are any
people in the area, promptly instruct them to
go away.
DDANGER
Do not fly at high altitudes higher than 3 to
4 meters (above ground or crop). In the
failsafe mode, the engine will stop auto-
matically after the allowable time, which
has been preset for safety, has elapsed.
Flying at an altitude that is higher than
necessary will cause the helicopter to drop
suddenly during an automatic descent in
the failsafe mode.
The automatic control in the failsafe mode
varies depending on the GPS reception
conditions (see the next page and thereaf-
ter).
Be sure to adhere to the indicated
“Actions”. Failure to take appropriate
actions can cause the helicopter, after
recovering from a radio signal interfer-
ence, to make an unexpected move or sud-
den descent, which can lead to accidents.
Verify the cause of the radio signal inter-
ference, and never perform subsequent
flights until the cause has been eliminated.
Failure to observe this precaution can
cause the helicopter to become inoperable
again, which can lead to accidents.

Automatic control (operation) in the failsafe
mode when GPS reception is favorable
1When a radio signal interference occurs, the red
and yellow warning lamps will rapidly illuminate
alternately, and automatically effect brake con-
trol. The helicopter will hover (for approximately
10 seconds), and will automatically start a slow
descent.
If the operating radio signals recover during the
descent, the control will switch automatically to
operator operation. Therefore, calmly set the
sticks on the transmitter to their neutral (center)
position, and wait for the recovery.
2If the helicopter makes an emergency landing
because the radio signals did not recover, the
engine will stop approximately 15 seconds later.
The helicopter could topple, depending on the
terrain on which it has descended, weather con-
ditions, or flight conditions. If the helicopter top-
ples, never approach it until the engine has
come to a stop.
3After the emergency landing, place the throttle
stick in its slowest position, and wait for the radio
signals to recover or the engine to stop.
4If the radio signals remain unrecovered after the
failsafe mode (radio signal interference) is
tripped, and the helicopter cannot determine
whether it has landed, the engine will stop auto-
matically approximately 60 seconds later.
Wait until the main rotor completely stops rotat-
ing before approaching the helicopter and turn-
ing the main switch OFF.

Automatic control (operation) in the failsafe
mode when GPS reception is poor
1When radio signal interference occurs, the red
and yellow warning lamps illuminate alternately
at a quick pace, and the system forces the heli-
copter to descend rapidly. If the operating radio-
waves recover during descent, the control will
switch automatically to operator control. There-
fore, calmly set all the sticks on the transmitter in
their neutral (center) position and wait for the
recovery.
2If the helicopter makes an emergency landing
because the radio signals did not recover, the
engine will stop in approximately 10 to 15 sec-
onds.
The helicopter could topple, depending on the
terrain on which it has descended, weather con-
ditions, or flight conditions. If the helicopter top-
ples, never approach it until the engine has
come to a stop.
3After the emergency landing, place the throttle
stick in its slowest position, and wait for the radio
signals to recover or the engine to stop.
4If the radio signals do not recover after 15 sec-
onds have elapsed from the time the failsafe
mode (radiowave interference) has been tripped,
the engine will stop automatically even if the heli-
copter does not make an emergency landing.
5If the helicopter makes an emergency landing,
wait until the main rotor stops rotating before
approaching the helicopter and turning the main
switch OFF.

The GPS-based speed control functions by receiv-
ing radio signals from 4 or more satellites. This con-
trol might become unusable, depending on the
surrounding environment, terrain, weather condi-
tions, time of the day, or other reasons.
If GPS reception becomes poor while using the
GPS-based speed control flight mode, the safety
function will cause the yellow warning lamp to flash
irregularly, automatically effecting the control (oper-
ation) or switching the flight mode as described
below. Thoroughly familiarize yourself with this
function, and take appropriate actions.
When GPS reception becomes poor, the yellow
warning lamp will flash irregularly at the same time.
After the flight mode switches completely to pos-
tural control, the yellow lamp will change from irreg-
ular flashing to regular flashing. After that, the
control will transfer smoothly from speed control to
postural control.
Safety Functions and Actions in Case GPS
Reception Becomes Poor While Flying Under
Speed Control
If the yellow lamp transfers to regular flash-
ing, the flight mode will not revert to speed
control even if GPS reception improves. It
will revert if the GPS switch is turned back
ON after GPS reception improves.

The reception of GPS radiowaves can become poor
due to the conditions described below or other rea-
sons.
1Presence of obstacles near the location of the
flight, such as mountains, trees, or buildings.
2There are people around the antenna.
3The number of satellites transmitting radio sig-
nals diminishes, because of the time of the day.
