Duplex DC-24 II - Carbon Line Ruby lacquer


DC/DS Transmitters

Precise RC transmitters benefit from all of the features that the Duplex 2,4GHz EX system can offer.

The transmitters contain an advanced user interface that allows you almost unlimited programming. On-line and off-line telemetry are available as well as alarms, custom audio playback etc.

The design goals were maximum utility, durability, and reliablity of their mechanical parts along with simple handling. The metal case, with its chemically resistant finish, provides maximum protection for the interior components. The straightforward case shape makes servicing easy. The control gimbals, ball bearing equipped with their magnetic Hall sensors are another revolutionary design concept used to make the DC/DS among the world’s most advanced R/C systems.

Purposefully placed at the top of the transmitter, the 3.5" sunlight readable color LCD with its wide viewing angle offers nearly perfect visibility in just about any lighting condition. Thanks to its high resolution display and use of a relatively large number of graphic images it was possible to create a simple and intuitive setup procedure for displaying telemetric data.

The DUPLEX EX family of products have been equipped with an improved real-time telemetry system which can be viewed on the LCD transmitter display. The transmitter allows the setup of voice notifications, both preinstalled and user created, which can be related to telemetric values, user set alarms, or signals which have been assigned to conditions of various control elements.

The DC series transmitters are designed for the Tray

The next generation of the DC-24 II transmitter series with a unibody design offers a redesigned and even lighter frame for better user comfort. Now in addition to supporting Bluetooth connection to smartphones. A very powerful processor with a large memory enables high-quality texture settings and the use of a higher resolution on a completely new and larger display. The transmitter has a new graphical interface JUi2.
