cations is operated by way of radio signals. To prevent the helicopter from going out of control due to unexpected radio signal inter-

ference, pay careful attention to the radio sig-

nals before and during a flight. WWARNING 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 fly up with the wind (such as mowed grass, plastic tape, plastic bags, etc.). WWARNING Cancel a flight or aerial application plan if poor weather conditions exist as described below. Failure to do so could pose operation difficulties, which could lead to an accident, and 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 meters above the ground. Rain, fog, or lightning in the vicinity. WWARNING Keep the maximum horizontal distance between the operator and the helicopter within 150 meters. Keep the height of the helicopter between 3 and 4 meters from the ground or the crop. If the distance is any greater, it will prevent the operator from mon-

itoring the posture of the helicopter and adversely affect signal reception. For safety, further shorten the distance if there are any obstacles in the area. Failure to fly the helicopter within the maxi-

mum distance limit could lead to an accident. 1-9 Rain, Fog, or Lightning 150 m max 3 to 4 m WWARNING Adjust the load to leave some leeway in pay-

load. 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. There-

fore, hover the helicopter to check that there is an ample margin in payload before con-

tinuing with the flight. WWARNING If, during a flight, the warning lamp indicates an abnormal condition or the helicopter exhibits an abnormal behavior or symptom

(vibration, sound, coolant leakage, foul odor, etc.), immediately land the helicopter in a safe area. Failure to discontinue the flight can lead to an accident. WWARNING Bring the following items with you to the fly-

ing site. Failure to do so could adversely affect the flight and lead to an accident.

TIP 3-6 Part Names and Functions GPS switch Turning the GPS switch ON enables helicopter speed control through the use of the GPS function

(to maintain a constant flight speed). The GPS switch can be used while it is turned ON before takeoff. The flashing of the yellow warning lamp indicates that the reception of the GPS sig-

nals is poor, and the speed control function is unus-

able. In the situation indicated below, momentarily turn the switch OFF; then, turn it back ON. Otherwise, you will not be able to use the speed control flight mode. GPS Switch Speed control OFF Speed control ON Indications Yellow lamp Indication conditions Regular flashing Indication meanings Actions Unable to effect speed control Poor GPS signal reception Able to fly under postural control NNOTICE If a failure occurs in postural control, it switches to manual operation and disengages the speed control. Even if GPS signals are being received, the accuracy of the radio signals from the satellites may be poor. In that case, the helicopter might move front-back, side-to-side, or up and down. When this hap-

pens, quickly turn the GPS switch OFF. To use the speed control again, wait a while before turning the GPS switch ON. 3-7 Part Names and Functions Spray Switch ON (to operate) Push OFF (to stop) Release Spray switch When the flight transmitter is powered ON and the helicopter main switch is in the ON position, the sprayer can be operated.

When the helicopter enters the failsafe mode, it will descend automatically. See the page regarding the fail-

safe mode. 3-12 Part Names and Functions Safe Functions During Failsafe Mode

(Radio Signal Interference) 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. DDANGER radio signal During 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. WWARNING 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). to the to adhere Be sure 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. 3-13 Part Names and Functions Radio signal interference!

Hover, then descend slowly Brake control Automatic control (operation) in the failsafe mode when GPS reception is favorable 1 When 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. 2 If 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. 3 After the emergency landing, place the throttle stick in its slowest position, and wait for the radio signals to recover or the engine to stop. interference) 4 If the radio signals remain unrecovered after the failsafe mode (radio signal 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. 3-14 Radio signal interference!

Quick descent Part Names and Functions Automatic control (operation) in the failsafe mode when GPS reception is poor 1 When 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. 2 If 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. 3 After the emergency landing, place the throttle stick in its slowest position, and wait for the radio signals to recover or the engine to stop. 4 If 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. 5 If the helicopter makes an emergency landing, wait until the main rotor stops rotating before approaching the helicopter and turning the main switch OFF. 3-15 Part Names and Functions Safety Functions and Actions in Case GPS Reception Becomes Poor While Flying Under Speed Control 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. NNOTICE 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. ON OFF ON Poor GPS reception!

Transferring grad-

ually to postural control 3-16 Part Names and Functions The reception of GPS radiowaves can become poor due to the conditions described below or other rea-

Battery storage NNOTICE Do not use the battery or leave it in an area exposed to direct sunlight or in other high-

temperature areas such as inside a sun-

scorched car. Store it between -20 C and 50 C. 4-2 Pre-Flight Preparation Charging and replacing the sprayer transmitter battery (sold sepa-

rately) Battery cover Charging jack Dedicated charger NNOTICE Make sure to use a fully charged battery. An insufficiently charged battery can lead to a sprayer operation failure. Charging the battery Be sure to use a dedicated charger to charge the battery. Charge it as follows. 1 Make sure the power switch on the transmitter is OFF. 2 Remove the battery cover from the bottom. 3 Insert the chargers plug into the charging jack at the bottom of the transmitter. 4 Insert the power plug into the outlet. 5 The pilot lamp of the charger will illuminate, thus charging the battery. Refer to the following for the batterys charging time and standard operation time. Charging temperature range: 0 to 40C Charging time: 10 hours Standard operation time: 2.1 to 3.3 hours 6 After charging is complete, reattach the battery cover. NNOTICE If a battery is new or has been in long stor-

age, its operation time after the initial charge can be shorter than normal. In this case, the batterys normal performance with respect to the operation time will recover after several times of repeated charging and discharging. Please remember about this aspect during an initial use. 4-3 Pre-Flight Preparation Fuel tank cap Fuel and refueling This product uses regular gasoline. Do not mix engine oil with gasoline. 1 Have regular gasoline ready. Use fresh gasoline purchased recently (within 1 week) from a gasoline station. 2 Remove the fuel tank cap and start refueling. Make sure the filter net is attached to the filler inlet. WWARNING Stop the engine before refueling and do not bring a source of fire in the vicinity. Do not pour fuel over the refueling limit

(the red line marked in the filter net). Excess fuel can ooze out during flight, which is dangerous. After refueling, securely tighten the fuel tank cap. NNOTICE Fuel tank The fuel can spray out of the tank during storage or transport in a vehicle with high temperature. Refueling limit (red line) Filter net 4-4 Pre-Flight Preparation Precautions for Initial Flight Following Periodic Inspection Fuel After the helicopter undergoes a test flight following the completion of a periodic inspection at the dealer, the fuel is drained from the fuel tank. This prevents the fuel from getting stale while the helicopter is being stored by the customer. Before the customer takes the helicopter on an initial flight, fill the tank with fresh gasoline purchased recently

(within 1 week) from a gasoline stand. Never use leftover fuel. Doing so can cause the engine to start poorly or other malfunctions. NNOTICE Helicopter battery Because the tank was drained of its fuel, it will take a while for the fuel to reach the engine. If the engine does not start within 5 seconds after the starter switch is pressed, allow the starter to rest for about 10 seconds. This is done to allow the battery voltage to recover and to cool the starter motor. Then, press the starter switch again. If the starter motor spins weakly, replace the helicopter battery or recharge it with a dedicated charger. NNOTICE Never attempt to recharge the battery with an automobile charger or to connect it to an automobile battery through the use of booster cables. Doing so can damage the helicopters electronic compo-

nents. Initial flight procedure A periodic inspection consists of inspecting various components of the helicopter as well as performing a completion test flight. Following a periodic inspection, an initial flight should be performed calmly, in order to break in the various components and to allow the operator to get accustomed to piloting. 1 Fill the tank with fresh fuel. Set the chemical and water payload to 50 percent of a normal flight. 2 Perform a pre-flight inspection. 3 Start the engine, take off, and allow it to hover for a minimum of 2 minutes at a maximum altitude of 1 meter above ground. 4 In the next stage, mainly hover at 2 to 3 meters above ground. Set the maximum flare angle at 10 degrees, the maximum flight speed to 10 km/h, and steer gently to fly for a minimum of 10 minutes. At this time, make sure there are no malfunctions in terms of helicopter vibration, noise, and the helicopter movement in response to the operation of the sticks. 5 When landing the helicopter for refueling, be sure to turn off the engine, and observe that the main rotor has stopped rotating. Then, open the side cover and visually inspect for coolant or oil leaks. 6 After a flight, perform a post-flight inspection, cleaning, and service. 4-5 Handling the Helicopter Transporting the helicopter WWARNING The muffler reaches a high temperature immediately after a flight. To prevent burns, do not touch it. Be careful not to poke your eyes with the antenna or the like. NNOTICE Be sure to remove the chemical tank from the sprayer. If the helicopter is equipped with a liquid sprayer, fold the boom before transporting. Refer to the sprayer owners manual for details. Make sure the main rotor blades do not come in contact with the ground or sur-

rounding objects. Doing so will result in equipment damage. Do not hold the helicopter by the tail body, tail cover, radiator, or antenna. Doing so will result in equipment damage. Before moving the helicopter, be sure to turn the main switch OFF. Failure to do so can transmit shocking impacts to the sen-

sors, causing the helicopter to operate unintendedly. To transport the helicopter by rolling it on the ground, be sure to attach transport wheels (sold separately). Transport wheel (sold separately) installation and removal To transport the helicopter by rolling it on the ground, attach transport wheels to the front of the runners. Installation (and removal) is performed by 2 persons as follows. 1 Use your foot or hand to lower the stone guard, in order to lift the front end. 2 Install (or remove) the transport wheels in the recess located between the wheel and the pipe in the front of the runner. Pre-Flight Preparation Chemical tank Boom Stone guard Runner Transport wheel 4-6 Pre-Flight Preparation Moving forward/backward Lift the tail slightly by holding the grip handle of the stone guard to move the helicopter forward (or backward). NNOTICE Make sure to hold the grip handle to move the helicopter forward or backward. Do not hold the tail cover or antenna, as this could lead to equipment damage. Lifting and lowering 1 Make sure that 2 persons or more lift the helicop-

ter, with each person holding the runner as shown. NNOTICE Do not hold the helicopter by the exhaust pipe of the muffler or the bar for attaching the sprayer tank, as this could lead to equipment damage. Transport carefully so as not to damage the tail rotor. Grip handle Stone guard 4-7 Transporting WWARNING Use a truck to transport the helicopter. Do not attempt to fly the helicopter to another site, as this could lead to an accident. NNOTICE Make sure to remove the main rotor blades before transporting the helicopter. 1 Use a truck to transport the helicopter. 2 Remove the main rotor blades before loading the helicopter on a truck bed. (Refer to page 4-12.) Pre-Flight Preparation 4-8 Pre-Flight Preparation Checking radio signal interference Because this product is operated by radio signals, the presence of radio signals with the same fre-

quency in the vicinity will cause the signals to cross, which will adversely affect the control of the flight. Before a flight, be sure to use a radio signal moni-

tor, which is sold separately, to check the radio fre-

quencies that are being transmitted in the area.

(See the operation manual of the radio signal moni-

tor for its operation procedure.) During monitoring, make sure the power switch for the helicopter transmitter is turned OFF. WWARNING The unmanned helicopter for industrial applications uses radio signals to operate. Because the helicopter can go out of con-

trol due to unexpected radio signal inter-

ference, pay particular attention to the presence of radio signal interference before and during a flight. Cancel the flight if you detect the same fre-

quency that you will be using in the vicin-

ity. Otherwise, the radio signal interference could render the helicopter out of control, and could lead to serious accidents. Check for radio signal interference regu-

larly, including during breaks between flights. Check for radio signal interference each time you move to an area other than an adjacent area. The dedicated sprayer transmitter also uses radio signals to operate the sprayer. The sprayer could be rendered inoperable due to unexpected radio signal interference or the effects of surrounding obstacles. 4-9 Radio signal distance test Perform a radio signal distance test to make sure there are no malfunctions. Before performing this test, set the transmitter power ON and the helicopter main switch ON. 1 Retract the transmitters antenna to its shortest position. 2 The operator to operate the transmitter and the checker to check the helicopter should stay apart by maintaining an approximate distance of 50 meters between the helicopter and the transmit-

ter. 3 Make sure the servos operate properly in accor-

dance with the operation of the transmitter. If the radio signal reaching distance is less than 50 meters, cancel the flight and contact the dealer for a repair. WWARNING If the radio signal reaching distance is too short, the failsafe mode (radio signal interfer-

ence) might kick in during flight. Pre-Flight Preparation 50 m 4-10 Pre-Flight Preparation Main rotor installation and removal and tail rotor inspection Main rotor installation and removal Inspect the rotor for damage or dirtiness. Main rotor installation 1 Insert the main rotor blades into the blade holder. Hex wrench NNOTICE Mark Retaining bolt There are two main rotor blades: right and left. Install them by matching the color marked on the respective main rotor blade to the blade holder. Each main rotor blade has a top and bot-

tom. Install it so that its leading edge is oriented in the direction of rotation as shown in the cross section diagram. from being To prevent the top and bottom of the main rotor inter-

changed, there is a recess in the rubber damper on the main rotor side, and a pro-

trusion on the rubber damper on the blade holder side. inadvertently 2 Use an 8 mm hex wrench to tighten the retaining bolts. Check the tightening of the retaining bolts as fol-

lows. Tighten each retaining bolt until it comes to a stop. Then, back it out between 45 and 90. Make sure they are 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 shaken verti-

cally, and if they move smoothly with a small force applied in the direction of rota-

tion. Both rotor blades should be tightened about equally. Check that the main rotor blades move smoothly by moving them slightly in the direc-

tion of rotation. They are designed to stop by coming in contact with rubber stops if they are moved extensively. 4-11 Blade holder Mark Main rotor Rotation direction Align the groove with the bolt Cross section diagram Rotation direction Retaining bolt Main rotor No wobbling in this direction Moving smoothly in rotation direction Main rotor removal The removal is the reverse (2 1) of the installa-

tion. Pre-Flight Preparation Main rotor inspection Inspect the main rotor surface for dirtiness, cracks, fissures, or chipping. Inspect the cushion tape for peeling or other damage. Cushion tape Tail rotor inspection Inspect the tail rotor surface for dirtiness, cracks, fissures, or chipping. Inspect the cushion tape for peeling or other damage. Inspect that the tail rotor moves smoothly in the rotation direction. If a rotor blades surface is dirty, use household detergent on a soft cloth, wring the cloth, and use it to wipe the rotor blades surface. If the rotor blade is damaged, cancel the flight and request a repair by your dealer. NNOTICE If a main or tail rotor blade does not move smoothly or is damaged, it could generate noise or vibration. The main rotor and the tail rotor are impor-

tant components. Handle them carefully. Cushion tape 4-12 Pre-Flight Preparation Side cover installation and removal Side cover removal 1 Undo the 7 rubber hooks that are located along the top of the helicopter by lifting them as shown on the right. 2 Open the side covers from side to side. 3 To completely remove a side cover after it is open, hold the retaining hooks to pull the side cover sideways and remove it from the frame. NNOTICE Do not hold a side cover during removal, as this could lead to damage. The side cover can break if direct force is applied to it. Open the side cover slowly so as not to scratch the side cover. Side cover installation Reinstall the side covers in reverse order of removal. TIP Reinstall the side cover by aligning the cut-

out in the center of the side cover with the bracket in the center of the payload bar. NNOTICE Place the right and left side covers and lock them in place by engaging the 7 rubber hooks. 4-13 Rubber hook Side cover installation position Flying Procedure Flying Precautions ....................................................................... 5-1 Engine Starting ............................................................................ 5-3 Pre-start checks ....................................................................................................... 5-3 Engine starting ......................................................................................................... 5-4 Takeoff Precautions and Checks................................................. 5-6 Takeoff procedure.................................................................................................... 5-6 Post-takeoff checks.................................................................................................. 5-7 Flight Modes ................................................................................ 5-8 5 Landing and Engine Stopping...................................................... 5-9 Landing .................................................................................................................... 5-9 Engine stopping ....................................................................................................... 5-9 General aerial application pattern .......................................................................... 5-11 Flying Procedure Flying Precautions Preparation - Takeoff WWARNING 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 paper, plastic tape, empty bags, mowed grass, etc.). Do not operate the rudder extensively right before a takeoff, as this will cause the helicopter to move abruptly in the direction of the rudder after the takeoff. NNOTICE Takeoff - Hovering WWARNING 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. Hovering - Flying WWARNING 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 opera-

tor from monitoring the posture of the helicopter and adversely affect the signal reception condi-

tions. 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. 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. NNOTICE 5-1 Flying Procedure Flying - Landing WWARNING 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 warning 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 acci-

dent. 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 remove the battery in the transmitter. Failure to observe these precautions will trip the failsafe device (automatically turning the speed control ON), which will cause the engine to accelerate suddenly. Never enter the area within 20 meters of the helicopter until the main rotor has stopped com-

pletely and the engine has stopped. Also, do not allow other people to approach this area. Enter-

ing the area within 20 meters can lead to a serious accident. 5-2 Flying Procedure Engine Starting Pre-start checks 1 Check that the trim positions on the transmitter are proper, extend the antenna, and press and hold the power switch ON. If the amount of trim deviates greatly from the center, the buzzer will sound 3 sets of 4 beeps. When this happens, return the trim lever to its normal position. Be sure to charge the battery before use. Due to the nature of the lithium-ion battery, the buzzer may beep 4 times, even if the battery is not fully charged. If a low voltage warning is emitted, promptly replace or recharge the bat-

tery. 2 Turn the helicopters main switch ON. The system performs control configurations and self checks. Check that the flight lamps on the control panel flash regularly during configuration. Also, check that all the warning lamps on the back of the heli-

copter illuminate. If there are no problems, the flight lamp on the con-

trol panel will turn off, and the warning lamp will illu-

minate blue, indicating that the control configuration has completed. NNOTICE Do not move the helicopter during config-

uration. Configuring the control with the helicopter tilted could cause errors. Therefore, it is recommended to select a flat area for this purpose. 5-3 Main switch Flight lamp OFF O N STARTER Starter switch Control panel Engine starting 1 Check that the transmitters flight switch is in the START position. 2 Check that the transmitters throttle stick is in the slowest position. 3 Check again that the elevator trim lever, rudder trim lever, and aileron trim lever are in their neu-

tral position. 4 Press once the engine stop switch on the trans-

mitter. The flight lamp on the control panel will illuminate, enabling the engine to start. WWARNING If the elevator trim lever, rudder trim lever, or aileron trim lever are in a position other than neutral, the helicopter might not ascend straight up during takeoff. 5 Fully check (by point and call, etc.) the surround-

ings for safety. Flying Procedure Flight switch Engine stop switch Elevator trim lever Rudder trim lever Aileron trim lever Throttle stick 5-4 Flying Procedure 6 Stand on the left side of the helicopter, and while securely supporting the main rotor, keep the throttle stick at the slowest position with your right thumb, and press the starter switch with your left hand. WWARNING Support the main rotor with your body as shown in the illustration. Otherwise, the rotor could strike and injure you if the helicopter is improperly adjusted (such as the idle speed being too high or the clutch being engaged). NNOTICE If the engine does not start within 5 sec-

onds after the starter switch is pressed, allow the starter to rest for about 10 sec-

onds. This is done to allow the battery voltage to recover. Then, press the starter switch again. The safety device will trip and prevent the starter motor from operating if any of the following conditions have not been met:

The power switch of the transmitter is ON. The transmitters flight switch is in START position. The throttle stick of the transmitter is in the slowest position. The engine stop switch was pressed down previously. 7 While making sure that the throttle stick does not rise, quickly walk away from the helicopter, to a minimum distance of 20 m. DDANGER Never turn your gaze away from the helicop-

ter when walking away from it. 5-5 20 m minimum Takeoff Precautions and Checks Flying Procedure Takeoff procedure 1 To fly under speed control, turn the GPS switch ON. If the GPS switch is OFF, the flight will oper-

ate under postural control. 2 Check that the throttle stick on the transmitter is in the slowest position. Then, set the flight switch to FLIGHT. The blue warning light will turn off, and the helicopter is ready to fly. 3 Gradually raise the throttle stick to enable the control to automatically increase the engine speed. 4 Slowly raise the throttle stick to take off. WWARNING Do not operate the sticks abruptly as this could cause the helicopter to lose balance and lead to an accident. NNOTICE Do not operate the rudder extensively right before a takeoff, as this will cause the heli-

copter to move abruptly in the direction of the rudder after the takeoff. If speed control cannot be used due to GPS signal conditions, turn the GPS switch ON, which causes the yellow warn-

ing lamp to flash. This will render the flight to operate automatically under postural control. GPS switch Throttle stick 5-6 Flying Procedure Post-takeoff checks Perform the following checks:

1 While the helicopter is hovering, make sure it behaves normally in response to the operations of the sticks. 2 When the sticks are kept still in their neutral posi-

tion while the helicopter is hovering, the helicop-

ter 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. WWARNING For the first flight of the day, allow the heli-

copter to hover for 1 or 2 minutes while the engine warms up, and check that the helicop-

ter operates normally. Failure to do so will prevent the engine from attaining the proper power, which could lead to an accident. Elevator trim lever Rudder trim lever Aileron trim lever 5-7 Flying Procedure Flight Modes Flight modes (postural control, speed control) This unit has 2 types of flight modes: postural control mode (GPS switch OFF) and speed control mode

(GPS switch ON). The postural control mode is for stabilizing the posture of the helicopter, and does not stop the helicopter when the stick is in the neutral position. The speed control mode is for stabilizing the helicopter speed, and controls the speed during a forward or backward flight, as follows. It maintains the speed at the point in time when the elevator stick is operated, causing the yellow warning lamp to illuminate. It maintains this speed even if the stick is set to the neutral position. Even if the elevator stick is tilted to the maximum position, the speed will not exceed 20 km/h. To stop, operate the elevator stick in the opposite direction (flare) of thrust. After the yellow warning light turns off, set the elevator stick to its neutral position. This will cause the helicopter to stop and hover. In the speed control mode, do not continue tilting the stick to its maximum level because it is dan-

gerous. WWARNING 5-8 Flying Procedure Landing and Engine Stopping Landing DDANGER Never allow anyone to approach within 20 m of the helicopter. 1 After hovering the helicopter over the landing point, gradually lower the throttle stick to land it. 2 The blue warning light illuminates 10 seconds after landing. To take off again without stopping the engine, set the flight switch momentarily to the START position, then to the FLIGHT position. The blue warning lamp will turn off, enabling the helicopter to fly. Flight switch Throttle stick Flight switch Rotor brake switch Engine stop switch Engine stopping 1 After the engine speed has dropped, press down the engine stop switch on the transmitter until the engine has come to a complete stop. 2 Place the flight switch to START. 3 Press the rotor brake switch. DDANGER Never enter the area within 20 m of the heli-

copter until the main rotor has stopped com-

pletely and the engine has stopped. Also, do not allow other people to approach this area. Entering the area within 20 m can lead to a serious accident. NNOTICE Do not press the engine stop switch before the engine speed has dropped. The rotor brake will not engage unless the throttle stick is in the slowest position. Use the rotor brake to stop the main rotor after the engine has stopped. Operating the stick while the rotor speed is high can cause the helicopter to tilt, which is dan-

gerous. 5-9 4 Before turning the main switch of the helicopter OFF, check the indications of the self monitor. If an error code appears, contact your dealer. Flying Procedure Self monitor Main switch OFF O N STARTER Power switch 5 Turn the main switch of the helicopter OFF. 6 Press and hold the power switch on the transmit-

ter to turn it OFF. WWARNING Observe the following until the engine has come to a complete stop:

Do not turn OFF the power switch of the transmitter. Do not remove the battery in the transmit-

ter. Failure to observe these precautions will trip the failsafe device (speed control turns ON automatically), which will cause the engine to accelerate suddenly. 5-10 Flying Procedure General aerial application pattern When operating an unmanned helicopter for the purpose of spraying agricultural chemicals, ensure safe oper-

ation, as well as the safety of humans, animals, agricultural products, and the environment during aerial appli-

cation. Example: Disease and pest control of a rice paddy Flight altitude:

Flight speed:

Flying interval: 3.75 m (using center nozzle), 5 m (using dropping method), or 7.5 m Wind velocity:

3 to 4 m above the field 10 to 20 km/h 3 m/s maximum Flying interval of 3.75 m (using center nozzle), 5 m (using dropping method), or 7.5 m Flight speed between 10 and 20 km/h W i n d Flight altitude 3 to 4 m above the field DDANGER When refueling, never enter the area within 20 m of the helicopter until the main rotor has stopped completely and the engine has stopped. Also, do not allow other people to approach this area. Entering the area within 20 m can lead to a serious accident. NNOTICE When GPS signal reception is favorable, if the flight speed in the postural control mode exceeds 20 km/h, the red warning lamp will illuminate (speed indication function). There-

fore, keep the flight speed low so that this lamp will not illuminate. 5-11 Post-Flight Cleaning and Servicing Post-Flight Cleaning and Servicing.............................................. 6-1 Washable areas ....................................................................................................... 6-1 Non-washable areas ................................................................................................ 6-2 Sprayer cleaning ...................................................................................................... 6-2 6 Post-Flight Cleaning and Servicing Post-Flight Cleaning and Servicing Agricultural chemicals, dust, dead bugs, and pollen could adhere to the helicopter after an aerial application. If they remain stuck to the helicopter, they will cause a chemical reaction, which will lead to rust, insufficient lubrication, sealant deterioration, and discoloring. To prevent these problems, use the methods described below to clean and service the helicopter after a flight, in preparation for the next flight. While cleaning, check all areas of the helicopter for any damage, abnormal wear, loose fasteners, etc. The helicopter is very hot immediately after a flight. Therefore, to prevent burns, clean it only after its temperature has lowered sufficiently. WWARNING Washing the helicopter with water will cause a sudden change in temperature, which could create problems in electrical parts. Therefore, clean it only after its temperature has lowered sufficiently. NNOTICE 4 1 2 2 2 3 Washable areas The helicopter may be washed by directly spray-

ing with a tap water hose. Do not use a high-pressure cleaner as it could enter the internal electronic components. 1 Side covers They may be washed only after they have been removed from the helicopter. Do not wash them in the installed state because the water could splash on other parts. 2 Tail body, warning lamp, frame, undercover 3 Leaves and runners 4 Radiator Clean it by using caution not to damage the fins. Do not spray high-pressure water from below. NNOTICE Do not use a high-temperature, high-pres-

sure cleaner to clean areas 1 to 4 above, as it could damage the film and paint on the sur-

face. After cleaning the washable areas of the heli-

(black cap) Battery This helicopter uses a sealed battery. It is not necessary to refill or inspect the battery fluid. To inquire about the proper recharging procedure or any problems with the battery, contact your dealer. WWARNING The battery produces flammable gas (hydro-

gen gas). Mishandling it could lead to an explosion resulting in injuries. Make sure to observe the following:

Fire is strictly prohibited. Do not short a circuit, cause a spark, or let any fire such as cigarettes come near. This could cause an explosion. Do not connect to the battery terminals in the wrong order. Doing so could cause a fire. Recharge in a well ventilated place. Place the battery upright for recharging. Keep gasoline, oil, or organic solvent from getting on the battery, as this could cause the battery case to crack. Do not drop it or apply any other strong impact. The battery fluid is diluted sulfuric acid. Contact with the skin, eye, or clothing could lead to a serious injury. Keep out of reach of children. First Aid In the unlikely event that the battery fluid gets on the skin, clothing, etc., immedi-

ately rinse with copious amounts of water. If it enters the eye, immediately rinse it with copious amounts of water, and seek medical attention. NNOTICE This is a sealed 12 V battery. This battery has been filled with fluid and charged. No fluid level inspection or refill-

ing is necessary. For recharging, use the dedicated sealed battery charger (sold separately). Contact your dealer for details. If the battery is to be left unused for a long time, remove the battery from the helicop-

ter, and recharge every 3 months. When replacing the battery, contact your dealer, and make sure to use a genuine battery. 7-1 Battery Removal Remove the battery only after consulting your dealer. 1 Be sure to turn the main switch of the control panel OFF. 2 Remove the undercover (do not disconnect the warning lamp wiring). 3 Remove the battery box cover. 4 Disconnect the batterys negative terminal, and positive terminal, in that order (as shown on the right). 5 Remove the battery from the helicopter. NNOTICE The proper procedure for removing the bat-

tery is to first disconnect the negative termi-
