We recommend using a ground station at all times with the X8.To set up a ground station, choose a platform below and visit3DR.com/download_softwareto installthe application.WindowsMission PlannerOS XAPM PlannerAndroidDroidPlanner 2Important Note About Vehicle Setup in Mission Planner and APM Planner:Your X8 has been pre-configured at the factory and is ready to fly. Re-performing thecalibrations on theInitial Setupscreen, including the mandatory hardware configurationsand setup wizard, can adversely affect the performance of your aircraft.iOS?There are currently no ground station applications available for iOS.7Power ManagementThe X8 is powered by a rechargeable lithium polymer (LiPo) battery. When fullycharged, the battery provides up to 15 minutes of flight time depending on payload,environmental conditions, and flying style. Flying with a gimbal, GoPro, and FPVsystem can reduce flight time by up to 5 minutes. Flying aggressively or in high windscan affect power consumption and reduce flight time. Monitor power consumptionusing the flight data display on the controller (press and hold theDNbutton).When the battery reaches the low voltage limit, the X8 will initiate a low battery failsafeand land automatically at the current position. (See page 20 for more information aboutfailsafes.) To avoid a low battery failsafe, monitor battery voltage during flight on thecontroller’s flight data display, and end your flight before the battery reaches the lowvoltage limit.ControllerPress and hold theDNbutton to view flight data.flight battery mAh consumed since armedAnother way to monitor power consumption is by using milliamp-hours (mAh).Monitor the mAh on the controller, and ensure that it does not exceed 8,000mAh (80% of the battery’s available capacity).

# Low Battery Failsafe Environmental conditions, payload, and flying style can affect power consumption. Use the controller’s flight data display to monitor the voltage of the battery during flight.

If the battery reaches 14 V, the X8 will land automatically at the current position, indicated by a blinking yellow status LED and a quick repeating tone. The X8 is programmed with a set of failsafe behaviors to prevent a crash in the event of a loss of one of the data or communication channels required for flight. Although certain failsafes have assigned LED indicators and tones, it is unlikely that you will be able to see these at a distance. Monitor the ground station for failsafe indications. If a failsafe is triggered, the assigned behavior will activate. To override the failsafe behavior, use the controller to switch to standard mode and regain manual control.

RC Controller Signal Failsafe Physical obstructions and interference from nearby wireless signals can affect

the X8’s connection with the controller.

If the X8 loses contact with the controller, it will return to the launch point auto

matically and land, indicated by a blinking yellow status LED.

# 21 

# GPS Failsafe

The X8 requires GPS lock before takeoff. Enclosed areas, physical obstructions, and lack of available satellites can affect GPS strength. If the X8 loses GPS lock in flight, it will trigger a GPS failsafe, indicated by a blinking blue and yellow LED with a high-high-high-low tone, and automatically switch to manual control (standard - altitude hold mode). Always be prepared to regain manual control at any time while flying and choose an unobstructed flying area to improve GPS signal strength. When flying a mission, we recommended changing the GPS failsafe behavior to land. (Visit 3DR.com/X8/info for more information about configuring the GPS failsafe.)

Altitude Failsafe The X8 has a 100 m (328 ft) altitude geofence enabled by default. If the geofence is breached, the X8 will automatically RTL. visual line of sight 400 ft (120 m)

# Range Failsafe The X8 has a 300 m (984 ft) horizontal geofence enabled by default. If the X8 travels farther than 300 m from the launch point, it will automatically return to the launch point and land. If you plan to fly a mission that exceeds this range, you will need to disable the horizontal geofence. (Visit 3DR.com/X8/info for instructions.) The range failsafe will be disabled in the event of a GPS failsafe.

Ensure that you feel comfortable operating the X8manually before attempting an autonomous mission.Environmental AwarenessBefore you fly, assess the features of your flying area. Determine the boundaries of the safe flying area, and be prepared to recover the copter manuallyif it goes outside this area. Be aware of any risks at your location, includingbodies of water, structures, trees, etc. Designate a few areas as safety zoneswhere you can safely land the copter in case of an unsafe situation.Radio Signal ConditionsFlying behind solid objects, like buildings and trees, will block radio signals.Always maintain visual contact with the copter to ensure that the radio signalis unobstructed. Radio towers, cell phone towers, and nearby WiFi signalscan also cause interference with the radio system and decrease its range.Avoid flying in populated areas to avoid sources of interference.AltitudeSelect an appropriate altitude for your flying location and local regulations.Remember the X8 will not avoid obstacles during a mission; it will completethe mission as planned. Select altitudes that avoid any obstacles, such astrees, and comply with the safety information in this manual.SpeedBy default, the X8 will travel at 6.5 m/s (14.5 mph) during a mission.PowerAs the operator, it is your responsibility to ensure that all missions complywith the X8’s operating limits, including flight time. Don’t forget to take intoaccount the effect of current wind conditions on power consumption.Regaining Manual ControlDuring a mission, keep the controller easily accessible, and be prepared toregain manual control at any time. To regain manual control during themission, switch to standard mode using the controller. If you observeinstability in the X8’s flight behavior or it the copter moves outside yourdesignated safe flying area, switch to RTL. Turning off the controller willautomatically trigger an RTL and can be used in an emergency situationas a hard recall command.FailsafesThe X8’s default failsafe behaviors are optimized for manual flight.
