Up to 6 BfT. Approx. 50km/h
The H520 can be flown from -10°C to about 40°C. Note that the battery shouldn’t be cold. A cold battery can lose up to 40% of its performance. At temperatures above 40°C, the electronics may experience a heat problem during continuous operation. The system may need to cool down now and then.
Temperature, payload, altitude and wind affect the flight time.
Resilience. The H520E can be landed safely also with 5 motors and is wind-stable and quieter than a Quadcopter.
If a propeller breaks down or a motor fails, the H520E will switch to 5 Motor Mode and keeps flying.
Max 2,5 kg (takeoff weight incl. copter).
The H520E uses GPS and GLONASS
The OBS is a forward faced system based on ultrasonic technology. If an obstacle is detected, the H520 will stop in 4,5m distance. Objects must be at least the size of a thumb to be recognized. The system can also be switched off. When the OBS is on, the airspeed is limited to 25 km/h.
Yes you can, but there is limited storage space. Make sure that no map is bigger than 100MB. This would slow down the system unnecessarily. Spread the area over several small maps instead.
Basically, whenever the copter is not flying stable in the air despite having GPS signal available or if the remote control in the DataPilot shows a red status code under “summary” or “sensors”. Calibration after changing the location is not necessary.
When calibrating, make sure that there is no metal around the drone. This can affect the internal compass. Check the joystick movements in the RC Monitor. If the reactions to your movements are slow, you need to have your controller checked.
There are two different radio links and two different types of connection losses. Communication lost – loss of image transmission (5.8GHz). The H520E remains fully controllable with all functions. As soon as the Copter regains a signal, the image transmission is restored.If the wireless connection is lost, the H520E automatically returns to the starting point. If the connection is restored during the return, RTL will not continue. The last known command will be executed.
The H520E calculates depending on distance and battery voltage when emergency RTL is triggered. This ensures a safe return to the starting point. (From version 1.4.9)
By lowering the stick “descend” and simultaneously pressing the red button three times, an emergency shutdown of the motors is triggered. Attention: Only use in an emergency case. A motor restart is not possible!
LiPo batteries are high-performance energy sources and require a certain amount of care.
Ideal for the care of the HV LiPo batteries is the Duo charger DY5 from Yuneec. This offers not only an automated charge and discharge (with two batteries at the same time), but also a setting for the storage of batteries.
Some basic rules for battery usage:
– Never empty the battery completely
– If a battery is not used for more than 2 weeks, please charge/discharge it to storage voltage
– Never use / charge the battery when it is very hot or cold
For the first 10 charging cycles, the battery should be flown down to a maximum of about 30% of its capacity. Later you can also fly below 20% of the capacity. Under 10% you should go as rarely as possible. The automatic function “emergency return” is an emergency program and should only be used in an emergency.
You get the best results at flying and charging when the battery has a temperature between 25° and 40°C. If the battery is very cold, it loses up to 40% of its capacity. Preheat the battery. Store batteries at room temperature or ideal is a tempering box. (Core temperature of the battery up to 40°C is ideal)
Like any tablet, the memory of the Android tablet in the ST16S is limited. It becomes less and less with more copies of images, videos, maps, missions and other apps. This slows down your system.
Please note the following instructions:
– Only save maps (max 100MB) that you need regularly
– Delete old pictures and videos from the ST16S from time to time
– Delete screenshots from the remote control from time to time
– Do not install any other apps on the remote control
The wear parts include: propellers, propeller mounts and batteries.
Propellers and propeller mounts are made of plastic and can wear out. If the propeller still has play after locking it, the propeller and propeller mount must be replaced. After 200 flight hours, this should definitely happen to all 6 arms. Upset impurities (dust and sand, for example) can pollute the bearings of the motors or can settle in the mechanics of the landing gear. Often a careful blow with compressed air will help. If this does not help, the corresponding part must be exchanged. Therefore, please contact our technical service.
