Are there any trouble/crash accidents in the past of SY450H?
No any trouble/crash accidents in the past of SY450H still now.

What’s the control range of SY450H?
The distance cover range can reach 150km.

Do you offer customization?
Sure. Customization of drone aircraft can be achieved easily and it is our biggest strength. You can raise your requirement for the customizing, then it will be processed by our professional managers. We offer a set of products and variations corresponding to various payload ranges.

Can you calculate MTBF of SY450H?
Around 300h. Actually, MTBF 300h is great higher than standard level in drone market.

SY450H, what is wireless communication control system?  -Wi-Fi /2.4 GHz ?  -900 MHz? - or only use GNSS?
We use 2.4GHz, usually we take 900MHz. we also use others . We can adjust our products wireless communication control system according every market requires.

In comparison with others drones, what are the benefits of  SY450H?
l High reliability in harsh environment : the flight control system adopts the robust control algorithm based on model, adaptive gust, high and low temperature, load change, center of gravity change and so on. It ensures the flight accuracy and reliability under harsh environment. At the same time, it is easy to disassemble and repair and maintain.
lLargest payload drone with smaller size than others. the maximum take-off weight is 450 kg, the maximum carrying capacity is 150 kg, which can effectively carry out various kinds of scientific research, detection and military equipment.
lLong sailing time: the standard fuel tank is 100 liters, which can ensure the effective flight time of 4 hours under full load condition.
lSY450H adopts a coaxial double deck rotor design to reduce the length of the aircraft and facilitate the transportation. Compared with the traditional helicopter, it has the characteristics of large load, low power consumption and high stability in hover.
lStrong power: the use of 115 horsepower turbocharged engine, to solve the problem of high power loss of high altitude flight engine, flight height can reach 5000 meters above sea level.

Why does the SY450H use the coaxial double-rotor layout?
l SY450H adopts the coaxial double-rotor layout, which can maintain high weight, aerodynamic efficiency and compact size at the same time.
l The longitudinal size of the coaxial helicopter is 60% of the single rotor, which is convenient for transportation and storage.
l Coaxial helicopter hovering efficiency is 17% to 30% higher than single rotor.

What are the advantages of the SY450H with rotary engines?
The rotary engine for helicopter has the advantages of high power to power ratio, high reliability, low noise and low power consumption, small vibration, smooth operation and easy maintenance. It is equipped with special clutch and output interface to match the demand of the helicopter.

Which loading modules can be carried by the SY450H?
The SY450H can payload aerial video transmission module (picture transmission), air megaphone, aerial multi-purpose throwing module, communication relay module and so on.

Is RTK standard?
The RTK technology of the SY450H is optional. The hovering accuracy of the SY450H without RTK technology is about ±1m. Using RTK technology, the plane accuracy range is ±8mm+1ppm and height accuracy is ±15mm+1ppm.

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.

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 its factory for the demonstration of our competence, sharing ideas and discussing face to face partnership. Contact us to arrange a meeting.

What do I have to bear in mind before my first flight?
l Make sure you are in an open and safe environment.
l Make sure the drone is placed on a flat surface.
l Keep in mind that surrounding electromagnetic signals might affect the performance of the drone.
l Compass Calibration is always highly suggested before each flight.
l Never start in normal mode and then switch to GPS mode when the drone is off the ground. The drone will only set the home location when taking off in GPS mode. This is the main cause of pilot error fly always as the drone will attempt to fly back to its previously set home point.

Is it possible to provide rental services and pilot services?
Yes, you don’t need to master the flight technology. We can provide drones and pilots according to your application needs. Please contact our sales manager.
