Whether the actual hovering time of the tethered drone can reach 24 hours?

In theory, tethered drone can last 24 hours. But for the protection purpose, it is better to land when it works for a long time. just like a TV ,it can keep working always, but we usually turn-off the TV after it working for a long time to extend its service life. We proposal to land every 8hours. Secondly, The drone is generally used for large-scale activities and communication relays. Large events generally lasts for 3-4 hours, and the communication relays are about 8 hours. During the period, tethered drone should be landed to do some inspection and fly again.

Does tethered drone require special heat dissipation after fly a long time?
Tethered drones are cooled by wind-cooling module . After long term testing, the temperature of battery and ESC which are included in power system are under controlled range. And the temperature of the motor is related to the payload. When under the higher temperature in summer, the UAVs can keep flying 8 hours with rated weight of payload, and temperature rising under control.

Is RTK standard?
The RTK technology of the tethered drone is optional. The hovering accuracy of the SY4000T without RTK technology is about ±1m. Using RTK technology, the plane accuracy range is ±8mm+1ppm and height accuracy is ±15mm+1ppm.

About the Tethered systems, can it adapt to other drones?

No. In general, the tethered drones are supposed to fly much longer time,(24*7 hours), need great intensity. And general multi-rotors can’t afford over large intensity of flying, which could cause the damage of the drones. Besides, the tethered drone need the airborne power to switch the ACV to DCV. Normal multi-rotors don’t include this module.

Which loading modules can be carried by the tethered drone?

Tethered drone can payload 30 times optical zoom optoelectronic pods, aerial megaphone module, communication relay module, aerial searchlight module and 10 times /20 times /30 times visible camera,etc.

Can it be used programmed for residential rooftop inspection of SY4000T?

Yes, it can be used for it. But it better to share us more information about how big the residential rooftop is, then we can give you best solution & purchasing suggestion.

Does the drone contain lightning protection modules?

The fuselage of the drones is made of carbon fiber. The fuselage itself is a conductor, which can export thunder and protect the internal parts of the fuselage. In addition, drones generally don’t fly in lightning weather.

In comparison with others drones, what are the benefits of the drones you provide?

l SY4000T has integrated design ,from flight control system ,hardware to power system , every parts had been designed for intensive tasks to make sure a long endurance with high stability. 

l The fiber cable of SY4000T can provide bi-directional signals from the aerial platform and its sensor, data transmission speed up to megabytes per second.

l SY4000T provides exceptional observation and surveillance capabilities, supports a variety of missions, including surveillance, border patrol, crowd monitoring, traffic control, communications relay, emergency rapid response, firefighting and disaster prevention.

l Rising to heights of 100 meters in 2 minutes with carrying payload up to 8 Kg.

l Highly portable, with pluggable arms.

The problem about drone’s price .

The price of drones varies mainly depending on the product and the loading conditions involved. For details, please consult our sales manager via Skype.

Do you provide warranty for your drones?

The warranty is valid for one year. Of course, there is a possibility of extending the warranty period, it’s depending on the volume of the order.

Do you provide after-sale service? What cover warranty?

Besides 24 hours contact availability, during the warranty period,Sunwin is also responsible for providing the replacing parts caused by drone itself. However, Sunwin will not take the responsibility if the malfunction is caused by the operators.

Do you provide instructions on how to operate a UAV?
Sunwin provides the UAV flight training, but the training will be exclusively offered in Beijing and Hefei, Anhui China. We have a professional UAV training institution authorized by CAAC, authenticated by AOPA. Teaching our customers how to use our UAV and professional engineers will give you the best technical support. It is completely free of charge (meals and accommodation are not covered) and takes 3~6 days to complete.

How could I become an official Sunwin distributor?

Sunwin welcomes potential distributors to pay a visit to our factory for the demonstration of our competence, sharing ideas and discussing face to face partnership. Contact us to arrange a meeting.
