8. Multi-drone control by one radio

Spread-spectrum technologies of advanced SHTT

It is based on SIYI Technology’s latest bidirectional 2.4GHz spread-spectrum technology named SHTT (SIYI Hopping Telemetry Technology) that is utilized to transmit and receive data using the DK32S transmitting system. By using the SHTT technology, one can achieve a stable flight control distance of up to 20km (unobstructed, interference-free). Through the use of a unique matching code, both the transmitters and the sky stations work together in harmony, achieving better anti-interference performance over and above the transmitters themselves, allowing for multiple transmitters to work in synchronization and stability at the same time.

Using extraordinary skill and accuracy to manipulate

As a result of the streamlined and compact industrial design, a delicate ergonomic design, and a still even more fashionably streamlined and compact industrial design, the SIYI DK32S transmitter perfectly fits into the palms of any user.
Moreover, a matte silicone pad provides an extra layer of protection on top of the silicone pad. You will be able to free your mind before departing on a flight by reading this collection of ideas and results.

Fast-response 16-channel multi-functional mode in this Radio controller

In addition to fixed-wings, helicopters, gliders, quadcopters and multi-rotors, the DK32S transmitter supports 16 channels of operation for a variety of aircraft models.
Data transmission over a distance of 20 kilometers with real-time monitoring
The DK32S transmitter can transmit a signal up to a distance of 20 kilometers in an unobstructed environment that is completely free of interference. This perfectly meets the requirements of the majority of users
Pilots of agricultural drones need to know their operating requirements for flights beyond the visual range (BVR). The DK32S transmitter comes with a built-in display that allows the user to view real-time telemetry data from the sensor
It will contain information about the voltage of the sky station, the power of the aircraft, the strength of the signal, and other data collected using multiple sensors.

Broadcasting of audio messages with vibration alerts in this remote controller

By combining the voice broadcast function with the vibration alert feature, users can spend more time concentrating on their flight.
Brand New GUI System and High Brightness Colorful LCD Touch Screen
SIYI DK32S transmitter’s high brightness colorful screen is clearly visible in sunlight. There are no conventional keys and buttons, but a built-in LCD
touchscreen on the transmitter, assisted by a turntable menu in the brand new GUI system. All these revolutionary enhancements features in both software and hardware provide a more user-friendly experience on transmitting settings.

Creative 5-dimensional Sub-trim Buttons

Sub-trim button designs in traditional transmitters have been overturned in the SIYI DK32S transmitter, now you are able to do quick adjustment between sub-trim buttons and joysticks in a flight. These buttons combine elegant aluminum alloy molding with the unity of industrial design to provide an exceptional manipulating experience.
Fulfils the Requirement of Advanced Models or Robots
SIYI’s DK32S transmitter can save 64 sets of model data by default. The amount can be extended to a substantial extent if necessary.

Powerful programmable mixing control supports various customized mixing patterns and curve mixing.Adjustable rate, editable throttle curve and pitch curve make any complicate control easy to operate.The data copy function provides convenience to users for sharing transmitter settings with friends.

It is possible to use two transmitters simultaneously in the trainer mode, one for the trainer and the other for the trainee. The trainer mode has a variety of protection options. An example of this is the trainer transmitter can take control of the flight from the trainee transmitter through a pre-defined switch.

With the channel mapping function, you are able to define your own channels; the failsafe function provides an additional layer of safety to the safety of your flight.
Battery with high capacity and built-in Lithium-Polymer
Featuring a high capacity 1S Li-Po rechargeable battery, the SIYI DK32S transmitter is easy to use, reliable, and easy to maintain. The DK32S transmitter has a standard Micro-USB port, which allows it to be charged easily, and it will work continuously for more than 12 hours after it is charged. The transmitter can operate outdoors for a long period of time without any problems.
Saving and extending SD Card data
Unlike the DK32S transmitter, which stores flight data on a SD card, this transmitter supports copying flight data from one transmitter to another afterwards.

Adjust Transmitter Settings and Upgrade Firmware on PC

The SIYI DK32S transmitter supports adjusting system settings and upgrading firmware through the PC software “SIYI Assistant”. It’s an obvious attempt to promote user experience, and SIYI Technology promises continuous firmware updates and other awesome features.
