Part Names and Functions3-13If the radiowaves for operating the helicopter does not reach the helicopter due to some kind of failure, thehelicopter becomes inoperable, which is very dangerous. When a radiowave interference occurs, the safefunction will cause the red and yellow warning lamps to rapidly illuminate alternately, and automatically effectthe 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, neverapproach the helicopter until the main rotorstops rotating completely, and the enginehas come to a complete stop. If there are anypeople in the area, promptly instruct them togo away.DDANGER●Do not fly at high altitudes higher than 3 to4 meters (above ground or crop). In thefailsafe mode, the engine will stop auto-matically after the allowable time, whichhas been preset for safety, has elapsed.Flying at an altitude that is higher thannecessary will cause the helicopter to dropsuddenly during an automatic descent inthe failsafe mode.●The automatic control in the failsafe modevaries depending on the GPS receptionconditions (see the next page and thereaf-ter).●Be sure to adhere to the indicated“Actions”. Failure to take appropriateactions can cause the helicopter, afterrecovering 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 subsequentflights until the cause has been eliminated.Failure to observe this precaution cancause the helicopter to become inoperableagain, which can lead to accidents.WWARNING
Part Names and Functions3-14●Automatic control (operation) in the failsafemode when GPS reception is favorable1When a radio signal interference occurs, the redand yellow warning lamps will rapidly illuminatealternately, and automatically effect brake con-trol. The helicopter will hover (for approximately10 seconds), and will automatically start a slowdescent. If the operating radio signals recover during thedescent, the control will switch automatically tooperator operation. Therefore, calmly set thesticks on the transmitter to their neutral (center)position, and wait for the recovery.2If the helicopter makes an emergency landingbecause the radio signals did not recover, theengine will stop approximately 15 seconds later.The helicopter could topple, depending on theterrain on which it has descended, weather con-ditions, or flight conditions. If the helicopter top-ples, never approach it until the engine hascome to a stop.3After the emergency landing, place the throttlestick in its slowest position, and wait for the radiosignals to recover or the engine to stop.4If the radio signals remain unrecovered after thefailsafe mode (radio signal interference) istripped, and the helicopter cannot determinewhether 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.Hover, then descend slowlyBrake controlRadio signal interference!
Part Names and Functions3-15●Automatic control (operation) in the failsafemode when GPS reception is poor1When radio signal interference occurs, the redand yellow warning lamps illuminate alternatelyat a quick pace, and the system forces the heli-copter to descend rapidly. If the operating radio-waves recover during descent, the control willswitch automatically to operator control. There-fore, calmly set all the sticks on the transmitter intheir neutral (center) position and wait for therecovery.2If the helicopter makes an emergency landingbecause the radio signals did not recover, theengine will stop in approximately 10 to 15 sec-onds.The helicopter could topple, depending on theterrain on which it has descended, weather con-ditions, or flight conditions.

Part Names and Functions3-16The GPS-based speed control functions by receiv-ing radio signals from 4 or more satellites. This con-trol might become unusable, depending on thesurrounding environment, terrain, weather condi-tions, time of the day, or other reasons.If GPS reception becomes poor while using theGPS-based speed control flight mode, the safetyfunction will cause the yellow warning lamp to flashirregularly, automatically effecting the control (oper-ation) or switching the flight mode as describedbelow. Thoroughly familiarize yourself with thisfunction, and take appropriate actions.When GPS reception becomes poor, the yellowwarning 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, thecontrol will transfer smoothly from speed control topostural control.Safety Functions and Actions in Case GPSReception Becomes Poor While Flying UnderSpeed ControlIf the yellow lamp transfers to regular flash-ing, the flight mode will not revert to speedcontrol even if GPS reception improves. Itwill revert if the GPS switch is turned backON after GPS reception improves.ON → OFF → ONNNOTICEPoor GPS reception!Transferring grad-ually to postural control
