The Spektrum DX4S is a new radio for the sport driver who wants a full-feature transmitter that’s suitable for bashing, boating, racing or rock crawling due to it’s four-channel flexibility, impressive software features and advanced ergonomics. 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 four-wheel steering, two user-defined mixes, on-the-fly mix rate control, ABS and more.

At the core of the DX4S is the frequency-agile, DSMR 2.4GHz protocol. DSMR is exclusive Spektrum technology that can be used with any type of land-based RC vehicle or boat. Its range and response, particularly in noisy 2.4GHz environments, is superb. It’s also backwards compatible with DSM, DSM2 and Marine-specific Spektrum receivers. Long-time 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.
