Spektrum DX4S transmitter only, DSMR receiver required to be purchased seperately.
The DX4S DSMR™ 4-Channel AVC™ surface radio system gives everyone from entry-level RC drivers to hardcore backyard bashers an impressive list of programming features plus the amazing stability of AVC (Active Vehicle Control™) technology. When AVC technology is in use, the first two channels of the DX4S operate steering and throttle. The second two let you independently adjust the amount of steering and throttle assistance AVC technology provides. This makes it easy to dial in the perfect amount of stability for different types of surface conditions and terrain.
AVC™ (Active Vehicle Control™) Technology
Using sensors and exclusive software, patent-pending AVC technology calculates a vehicle’s attitude many times per second and makes instantaneous corrections to steering and throttle so it stays precisely on the trajectory you command. The amount of steering and throttle stability provided can be adjusted to suit your skill level or driving style. Best of all, driving with AVC technology feels completely natural. There is no lag in response or limits on your control. You simply feel like you’re driving a finely tuned vehicle that handles beautifully at every speed.
About the SRS4210 AVC Receiver *Available Separately*
The waterproof SRS4210 lets you add the advantages of AVC technology to any RC car, truck or buggy.* It does so by combining the superb range and signal security of a 4-channel DSMR receiver with an AVC system in a single, lightweight unit. Installation is easy and no complex setup is required. Simply bind it to a Spektrum surface transmitter that’s compatible with AVC technology and calibrate.
When the AVC system is active, the SRS4210 functions as a standard 2-channel receiver, with the AVC system using the extra channels to let you independently adjust the amount of steering and throttle stabilization.
*Use of AVC receivers with RC boats is not recommended.
Frequency-agile DSMR™ Technology
The DX4S is built around frequency-agile, DSMR 2.4GHz technology. This exclusive Spektrum™ technology can be used in any type of surface application. Its range and response, particularly in noisy 2.4GHz environments, are superb.
