Safety Precautions
WARNING
The unmanned helicopter for industrial applications is operated by way of radio signals.
To prevent the helicopter from going out of
control due to unexpected radio signal interference, pay careful attention to any radio
signal interference before and during a flight.
WARNING
Select areas that are appropriate for takeoffs
and landings, as described below. Failure to
select an appropriate area could lead to an
accident.
● Select flat farm roads or vacant lots with
minimal foot or vehicle traffic.
● Check that there are no obstacles in the
vicinity.
● Check that there are no objects that could
be picked up by the wind (such as mowed
grass, plastic tape, plastic bags, etc.).
WARNING
Abort the flight or aerial application if poor
weather conditions exist as described below.
Failure to do so could pose operation difficulties, which could lead to an accident. In
addition, it could adversely affect the application and the effectiveness of the sprayed
chemicals.
● Wind velocity in excess of 3 m/s at a
height of 1.5 m above the ground.
● Rain, fog, or lightning in the close vicinity.
WARNING
Keep the maximum horizontal distance
between the operator and the helicopter
within 150 m, and the flight altitude at 3 - 4 m
(from the ground or from the crop). If the distance is any greater, it will prevent the operator from monitoring the posture of the
helicopter and adversely affect the signal
reception conditions.
For safety, further shorten the distance if
there are any obstacles in the area.
Failure to fly the helicopter within the maximum distance limit could lead to an accident.

Failsafe (Safety Function During Radio Signal
Interference) Actions
If the radio signals for controlling the flight do not reach the helicopter due to interference, the helicopter will be
rendered out of control, which creates a dangerous situation. In case of radio signal interference, the system
has a safety feature that alternately flashes the inner and outer lights of the red YACS warning lights and automatically effects the flight control described on the following pages. Thoroughly familiarize yourself with this
feature to take the appropriate actions.
DANGER
During signal interference, never approach
the helicopter until the main rotor has come
to a complete stop and the engine has
stopped. If there are any people in the area,
instruct them to leave the area immediately.
WARNING
● Do not fly any higher than 3 to 4 m (above
the ground or crops). When radio signal
interference occurs (i.e. when failsafe
mode is engaged), the engine speed is
automatically brought to idling state after
40 seconds. Flying at a higher altitude will
cause the helicopter to descend abruptly.
● Make sure to follow the “Actions”
instructed in the manual. Failure to do so
could cause the helicopter to move unexpectedly or descend suddenly once it
recovers from the radio signal interference, and could lead to an accident.
● Do not resume flying until you have verified and eliminated the cause of the radio
signal interference. Otherwise, you could
lose control of the helicopter again, leading to an accident. (See pages 4-9 and 425.)
3-12
RMAX.book Page 13 Tuesday, January 17, 2012 3:06 PM
Pre-Flight Inspection Items
● Poor GPS Reception (Outer Lights of GPS
Indicator Light Are OFF)
1 In the event of radio signal interference, the inner
and outer lights of the red YACS warning lights
will flash alternately and the system will force the
helicopter to descend quickly regardless of the
flight mode. If the control radio signals recover
while the helicopter is descending, the flight
mode will switch automatically to operator control. For this reason, calmly move all the sticks
on the transmitter to the neutral (center) position,
and wait for the signals to recover.
2 If the helicopter is forced to land because the
radio signals have not recovered, the engine is
brought to idle.
Depending on the terrain, weather, and flight
conditions, the helicopter could overturn. If the
helicopter overturns, never approach the helicopter, as the engine speed might not decrease.
3 After a forced landing, turn the throttle to the
slowest position and wait for the radio signals to
recover or the engine to stop.
4 If the radio signals do not recover after 1 minute
from the time the radio signal interference
occurred, the engine will stop automatically. After
the rotor has come to a complete stop, approach
the helicopter and turn OFF its main switch.

1 When radio signal interference occurs, the inner
and outer lights of the red YACS warning lights
will flash alternately, and the system will apply
the brake and force the helicopter to hover
regardless of the flight mode. Then, the helicopter will automatically start descending slowly. If
the control radio signals recover while the helicopter is descending, the flight mode will switch
automatically to operator control. For this reason, calmly move all the sticks on the transmitter
to the neutral (center) position, and wait for the
signals to recover.

Safety Features and Actions During Poor GPS
Signal Reception
The GPS control operates by receiving radio signals from 4 or more satellites. It may become inoperable depending on the surroundings, terrain,
weather conditions, time zone, and other reasons.
If the reception of GPS signals becomes poor while
operating in a GPS control flight mode (SG, CG, or
AG), a safety feature will cause the outer and inner
lights of the orange GPS indicator lights to flash
alternately. Then, the system will automatically
effect flight control or switch the flight mode as
described below. Thoroughly familiarize yourself
with this feature to take the appropriate actions.
● Operating in SG mode
As the GPS signal reception worsens, the orange
GPS indicator lights will cycle through “outer lights
ON > inner lights ON > OFF”, and the brake control
will be applied only in the longitudinal direction of the
helicopter. At this point, quickly turn OFF the GPS
control switch. Because GPS control cannot be used
even before the GPS control switch is turned OFF,
the helicopter will operate in the slow flight mode.
This flight mode is not suitable for aerial application.
In addition, GPS control will not resume even if the
GPS signal reception improves. When the GPS
control switch is turned OFF, the GPS indicator light
will turn OFF and control will switch to S mode.
Therefore, operate carefully.
NOTICE
If the stick on the transmitter is moved past
the neutral (center) position to stop the helicopter when it is flying forward or backward
in SG mode, the automatic brake control will
be applied together with the operator’s brake
control if the GPS control is canceled. As a
result, the nose of the helicopter will tilt up to
an excessive angle.
● Operating in CG mode
As the GPS signal reception worsens, the orange
GPS indicator lights will cycle through “outer lights
ON > inner lights ON > OFF”. Control will switch
automatically to C mode. At this point, quickly turn
OFF the GPS control switch and operate carefully.
When the GPS control switch is turned OFF, the
GPS indicator light will turn OFF.
● Operating in AG mode
As the GPS signal reception worsens, the orange
GPS indicator lights will cycle through “outer lights
ON > inner lights ON > OFF”. Control will switch
automatically to A mode. At this point, quickly turn
OFF the GPS control switch and operate carefully.
When the GPS control switch is turned OFF, the
3-15 GPS indicator light will turn OFF.

Radio Signal Interference Inspection
Because this product is operated by wireless radio
signals, the presence of radio signals with the same
or neighboring frequency in the vicinity will cause
the signals to cross, which will adversely affect the
control of the flight. Before a flight, use the supplied
radio signal monitor to check the radio frequencies
that are being transmitted in the area. (See the
operation manual of the radio signal monitor for its
operation procedure.)
During monitoring, make sure the power switch for
the flight transmitter is turned OFF.
WARNING
● The unmanned helicopter for industrial
applications is operated by way of radio
signals. To prevent the helicopter from
going out of control due to unexpected
radio signal interference, pay careful
attention to any radio signal interference
before and during a flight.
● Cancel the flight if you detect the same frequency that you will be using in the vicinity. Otherwise, the radio signal interference
could render the helicopter out of control,
and could lead to serious accidents.
● Check for radio signal interference regularly, including during breaks between
flights.
● Check for radio signal interference each
time you move to another area.

Payload Inspection
The actual payload of this helicopter varies considerably according to its operating conditions
(weather, temperature, humidity, terrain, obstacles,
etc.) and flying methods, as well as the helicopter’s
individual differences.
Use the graph on the following page as a rule of
thumb for adjusting the payload with some margin
to ensure a safe aerial application flight.
WARNING
Adjust the load to leave some margin in the
payload.
A takeoff with the maximum payload requires
maximum horsepower and careful flying
technique. An excess payload at this point
could lead to a serious accident. Make sure
to observe the following:
● Refer to the payload graph and check the
payload that meets your requirements.
● Check the payload margin by hovering.
● If the low speed warning flashes on the
YACS warning light, this means there is
not enough payload margin. Remove the
chemical tank on the right side before performing the flight.
● If the position of the throttle stick immediately after takeoff is clearly high, this
means that there is not enough payload
margin. Remove the chemical tank on the
right side before performing the flight.
NOTICE
● If the engine is cold or when flying for the
first time after a periodic inspection, as a
guide, adjust the payload to about half of
the capacity.
● Contamination of the main rotor blades by
pollen, etc., will cause the payload capacity to decrease. Clean it during breaks.
● If the cushion tape has a peel or a damage,
it can cause the payload capacity to
decrease. Cancel the flight and request a
repair by your dealer. (See page 4-22.)

installing them.
2 Use an 8mm hex wrench to tighten the retaining
bolts.
Check the tightening of the retaining bolts as follows:
● Tighten each retaining bolt until it comes to a
stop. Then, back it out between 45° to 90°.
Make sure it is not tightened or loosened
excessively, which could cause vibrations.
TIP
● The main rotor blades are properly
installed if their retaining bolts do not
wobble when the blades are moved vertically, and if they move smoothly in the
direction of rotation when a small force is
applied.
● Tighten both rotor blades to approximately
the same amount of torque.
● Check that the main rotor blades move
smoothly by moving them slightly in the direction of rotation. They are designed to stop by
coming in contact with rubber stops if they are
moved extensively.
How to Remove Main Rotor Blades
Remove the main rotor blades in reverse order of
installation.

Flying Procedure
Flying Precautions
This section summarizes the precautions for a series of operations from takeoff to landing, as well as for handling the helicopter. Some of the contents may overlap the instructions given at the Academy.
DANGER
Never approach (or allow others to approach) within 20 m of the helicopter until the main rotor has
come to a complete stop and the engine has stopped. Entering within 20 m of the helicopter could
cause a serious accident.
Preparation - Takeoff
WARNING
● Do not take off or land on sloping terrain, as this could cause the helicopter to overturn, or
adversely affect its control. As a rule, the helicopter should take off and land on a level surface.
Make sure to select an appropriate location before commencing a flight.
● Select areas that are appropriate for takeoffs and landings, as described below. Failure to select
an appropriate area could lead to an accident.
• Select flat farm roads or vacant lots with minimal foot or vehicle traffic.
• Check that there are no obstacles in the vicinity.
• Check that there are no objects that could get picked up by the wind (such as mowed grass, plastic
tape, plastic bags, etc.).
TIP
● Do not operate the throttle stick while the outer YACS warning light is flashing. The engine will
stop if the throttle stick is moved far up.
● Do not operate the rudder excessively right before a takeoff, as this will cause the helicopter to
move abruptly in the direction of the rudder after the takeoff.
● During takeoff, do not turn ON the GPS control switch, as this could cause the helicopter to not
ascend straight up.
Takeoff - Hovering
WARNING
● Do not operate the sticks abruptly as this could cause the helicopter to lose balance and lead to
an accident.
● For the first flight of the day, allow the helicopter to hover for 1 or 2 minutes while the engine
warms up, and check that the helicopter operates normally. Failure to do so will prevent the
engine from attaining the proper power, which could lead to an accident.
TIP
After takeoff, turn the GPS control switch ON while hovering. If this switch was ON during takeoff,
turn it OFF while hovering, and turn it back ON.
5-1
Chap5.fm Page 2 Wednesday, January 18, 2012 10:17 AM
Flying Procedure
Hovering - Flying
WARNING
● Adjust the load to leave some margin in the payload. A takeoff with the maximum payload
requires maximum horsepower and careful flying technique. An excess payload at this point
could lead to a serious accident. Therefore, hover the helicopter to check that there is an ample
margin in payload before continuing with the flight.
● Keep the distance between the operator and the helicopter within 150 m, and the flight altitude at
3 - 4 m (from the ground or from the crop). If the distance is any greater, it will prevent the operator from monitoring the posture of the helicopter and adversely affect the signal reception conditions. For safety, further shorten the distance if there are any obstacles in the area. Failure to fly
the helicopter within the maximum distance limit could lead to an accident.
TIP
● Do not turn continuously while banking in one direction for more than 10 seconds, as this will
cause the helicopter to drift as if the trim has shifted.
● Do not turn in the SG mode. Because the operation method for this mode is different from other
modes, the helicopter could make an unexpected movement.
Flying - Landing
WARNING
● Do not lower the throttle stick to the slowest position during a flight, as this could disrupt the
engine speed control and cause the helicopter to descend abruptly.
● If the YACS warning light or the GPS indicator light shows an abnormal condition, the helicopter
exhibits irregular behavior, or an unusual symptom occurs (such as vibration, sound, coolant
leakage, or foul odor), immediately land the helicopter in a safe area. Continuing with the flight in
this state could lead to an accident.
● Do not press the Engine Stop switch during a flight, as this will stop the engine and cause the
helicopter to descend abruptly. However, to force the helicopter to land in case of an emergency,
press the switch after making sure that it is safe to do so.
● Abort the flight or aerial application if poor weather conditions exist as described below. Failure
to do so could pose operation difficulties, which could lead to an accident. In addition, it could
adversely affect the application and the effectiveness of the sprayed chemicals.
• Wind velocity in excess of 3 m per second at a height of 1.5 m above the ground.
• Rain, fog, or lightning in the close vicinity.
● Observe the following until the engine has come to a complete stop after landing:
• Do not turn OFF the power of the flight transmitter.
• Do not take remove or replace the battery in the transmitter.
Failure to observe these precautions will trip the failsafe device (speed control turns ON automatically), which will cause the engine to accelerate suddenly.
TIP
During a takeoff or landing, if the engine speed does not decrease even if the throttle stick is lowered to the slowest position, calmly turn the YACS control switch OFF. This symptom could occur if
a takeoff operation is aborted or if there are a considerable number of landing shocks when the
helicopter lands.

5 The SETTING light on the check point indicator
flashes approximately 3 times (for 10 seconds),
and the system performs YACS control configuration and self checks.
Check that all the red YACS warning lights on the
back of the helicopter illuminate during configuration.
TIP
● Do not move the helicopter while the
“
” light is flashing.
● Configuring the YACS control with the helicopter tilted could cause errors. Therefore,
it is recommended to select a flat area for
this purpose.
● If the “
” light illuminates on the flight
indicator, first turn the main switch OFF;
then, turn it to START. If the “
” light
illuminates again or if the “
” light
continues to flash, contact your dealer for
repair.
If there are no problems, the “
” light of the
flight indicator will illuminate, indicating that the
YACS control configuration has completed.
6 After the YACS control configuration has completed and the YACS warning light has turned
OFF, the outer lights of the GPS indicator will
flash and the GPS control configuration will start.
• The outer GPS indicator lights will flash while
GPS control is being configured.
• The outer GPS indicator lights will change from
flashing to constant illumination when the GPS
control configuration has completed (which
take about 3 minutes).
• After the lights illuminate, turn ON the GPS
control switch on the transmitter. Then, check
that all the GPS indicator lights illuminate.
• After checking that all lights illuminate, turn
OFF the GPS control switch.

● Step 5 completes the pre-start checks if
you will not be using GPS control or if you
will be using it later during the flight.
● The length of time it takes to complete the
GPS control configuration varies according to GPS signal reception. If it takes too
long (the lights do not illuminate after 3
minutes), you will not be able to use GPS
control in the AG, CG, or SG mode. Operate the helicopter under YACS control until
the signal reception improves, which will
be indicated by the illumination of the
outer lights.

Post-Takeoff Checks
Perform the following checks:
1 While the helicopter is hovering, make sure the
helicopter behaves normally in response to the
operations of the sticks.
2 When the sticks are kept still in their neutral position while the helicopter is hovering, the helicopter will drift front-and-back and side-to-side,
depending on wind conditions. If the helicopter
drifts constantly in one direction, land it in a safe
area to make fine adjustments at the trim lever of
the transmitter.
WARNING
For the first flight of the day, allow the helicopter to hover for 1 or 2 minutes while the
engine warms up, and check that the helicopter operates normally. Failure to do so will
prevent the engine from attaining the proper
power, which could lead to an accident.

Flying Procedure
General Aerial Application Pattern
When operating an unmanned helicopter for the purpose of spraying agricultural chemicals, ensure safe operation, as well as the safety of humans, animals, agricultural products, and the environment during aerial application.
Example: Disease and pest control of a rice paddy
• Flight altitude: 3 to 4 m
• Flying speed:
10 to 20 km/h
• Flying interval: 5 or 7.5 m
• Wind velocity:
3 m/s maximum
Flying speed between
10 and 20 km/h
Affirmative!
Just passed 10 meters,
and 5 meters
Flying interval 5 or 7.5 meters
Flying height between
3 and 4 meters
Wind
DANGER
When performing tasks such as refueling,
never approach (or allow others to approach)
within 20 m of the helicopter until the main
rotor has come to a complete stop and the
engine has stopped. Entering within 20 m of
the helicopter could cause a serious accident.
TIP
If the GPS signal reception is good, the outer
YACS warning lights will illuminate if the flying velocity exceeds 20 km, regardless of the
state of the GPS control switch on the flight
transmitter (Velocity display function).
Control the flight velocity so that the outer
YACS warning lights do not illuminate.

Flying Procedure
Landing and Engine Stopping
Landing
DANGER
Never allow anyone to approach within 20 m
of the helicopter.
After hovering the helicopter over the landing point,
gradually lower the throttle stick to land it.
After landing, turns the GPS control switch OFF.
TIP
If the engine speed does not lower within 3
seconds after landing, turn the YACS control
switch OFF. This will lower the engine speed
to idle.
Throttle Stick
Engine Stopping
1 After the engine speed has lowered, press down
the Engine Stop switch on the transmitter until
the engine comes to a complete stop.
2 Press the Rotor Brake switch.
DANGER
Never approach (or allow others to approach)
within 20 m of the helicopter until the main
rotor has come to a complete stop and the
engine has stopped. Entering within 20 m of
the helicopter could cause a serious accident.
TIP
● Do not press the Engine Stop switch
before the engine speed has dropped.
● The rotor brake will not apply unless the
throttle stick is placed in the slowest position.
3 Before turning OFF the main switch of the helicopter, check the self monitor’s check point indicator and the malfunction area indicator lights for
any illumination or flashing.

Flying Procedure
4 Turn OFF the main switch of the helicopter.
Main switch
5 Turn OFF the power switch on the transmitter.
WARNING
Observe the following until the engine has
come to a complete stop:
• Do not turn OFF the power of the flight
transmitter.
• Do not take the battery out of the transmitter.
Failure to observe these precautions will trip
the failsafe device (speed control turns ON
automatically), which will cause the engine to
accelerate suddenly.

Flying Procedure
Precautions for First Flight After Periodic Inspection
Fuel
After your dealer performs the complete inspection flight for the periodic inspection, the fuels are drained from
the fuel tank and the carburetor, to prevent the fuel from becoming old during your storage.
When flying for the first time, create a mixed fuel with fresh gasoline purchased at a gasoline station shortly
before flying (within 1 week), and refuel to maximum capacity.
NOTICE
Never use leftover fuel as it could cause the engine to stop or operate poorly.
Onboard Battery
Since the fuel has been drained, it will take a while before the fuel circulates into the carburetor.
If the engine does not start within 5 seconds after pressing the starter switch, wait about 10 seconds to allow
the battery voltage to recover and the starter motor to cool down. Then, press the starter switch again.
If the rotation of the starter motor is weak, replace the onboard battery, or have your dealer recharge it with the
dedicated recharger.
NOTICE
Never charge with a recharger for car batteries, or connect to a car battery using a jumper cable.
The electronics (computers) in the helicopter could malfunction.
First Flight Procedure
In the periodic inspection, various parts of the helicopter are inspected, and a complete inspection flight is performed. However, when flying for the first time after a periodic inspection, at a practice session, for example,
fly the helicopter gently as a means for the operator to familiarize himself with the various areas of the helicopter as well as its maneuverability.
1 Fill up the tank with fresh fuel. Keep the chemical and water load to one half of the normal load.
2 Perform pre-flight inspection.
3 After the engine starts, take off and hover no higher than 1 m above the ground for 2 minutes or longer.
4 Next, while hovering 2 to 3 m above the ground, fly gently with flare angle of 10 degrees or less, at a flight
velocity of 10 km/h or less, for 10 minutes or longer. During this time, make sure that there is no vibration in
the helicopter, abnormal sound, or other abnormal behavior in response to the various stick operations.
5 When landing for tasks such as refueling, always wait until the engine has stopped, and the main rotor has
stopped rotating, then open the side cover to visually check the coolant and oil leakage.
6 After the flight, perform post-flight inspection, cleaning and servicing tasks.
