DX4S: Power in Your Grasp

If you're looking for a surface transmitter that can do it all, this is it. Not only does it give you the flexibility of four channels, but it includes an impressive array of programming features. This includes pre-set mixes like 4-wheel steering, two user-defined mixes, on-the-fly mix rate control, ABS and more.

At the core of the DX4S transmitter is the frequency-agile, DSMR 2.4GHz protocol. This exclusive Spektrum DSMR technology can be used with any type of RC surface vehicle, including boats. Its range and response, particularly in noisy 2.4GHz environments, are superb. It's also backwards compatible with DSM, DSM2 and marine-specific Spektrum receivers. Longtime Spektrum users won't need to replace the receivers they have unless they want the frequency-agility of a DSMR receiver for busy 2.4GHz environments.

* The typical telemetry range is 100-200 feet and will vary depending on the operating environment.
