FAQ - Frequently Asked Questions

What is the maximum windspeed I can fly the H520?
Up to 6 BfT. Approx. 52km/h
At what temperatures can the H520 be flown?
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 coninous operation. The system may need to cool down now and then.
Which factors can affect the flight time?
Temperature, payload, altitude and wind affect the flight time.
What are the advantages of 6 Propellers?
Resilience. The H520 can be landed safely also with 5 motors and is wind-stable and quieter than a Quadrocopter.
When does the H520 turn on 5 Motor Mode?
If a propeller breaks down or a motor fails, the H520 will switch to 5 Motor Mode and keeps flying.
What is the maximum take-off-weight of the H520?
Max. 2,5 k (takeoff weight incl. Copter).
Which satellite systems does the H520 use?
The H520 uses GPS and GLONASS.
How does the obstacle detection work?
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.
Can maps be stored on the remote control?
Yes, you can, but there is limited storage space. Make sure that no map is bigger than 100 MB. This would slow down the system unnecessarily. Spread the area over several small maps instead.
How often do I have to calibrate my H520?
Basically, whenever the copter is not flying stable in the air despite having a propper 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.
I´ve already re-calibrated the H520, but the drone still flies quite unstable. What should I do?
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.
