If youre looking for a surface transmitter that can do it all, the DX4S 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 is the frequency-agile, DSMR™ 2.4GHz protocol. DSMR is exclusive Spektrum™ technology that can be used with any type of RC surface vehicle, including boats. Its range and response, particularly in noisy 2.4GHz environments, is superb. Its also backwards compatible with DSM, DSM2 and Marine-specific Spektrum receivers. Longtime Spektrum users wont need to replace the receivers they have unless they want the frequency-agility of a DSMR receiver for busy 2.4GHz environments.
