The DX3 transmitter is built around proven Spektrum DSMR 2.4GHz frequency-agile technology. The range and response of DSMR technology is outstanding, particularly in noisy 2.4GHz environments. It can used with any surface application and is backwards-compatible with Spektrum DSM2 receivers.



The DX3 radio system supports the on-demand traction control of Spektrum AVC (Active Vehicle Control) technology. With an AVC system, you can dial in extra stability as needed to carve corners or nail jumps without backing off the power. You have full-throttle freedom over rough terrain, slick surfaces and loose dirt. When you dont want the extra traction, just dial back the stability and get loose. The DX3 transmitters AVC system works behind the scenes, making hundreds of minute steering and throttle adjustments per second to keep you precisely on the line you want to hold.



Integrated into the face of the DX3 Smart is a helpful Smart Battery voltage indicator. Drivers can easily find out the charge of their Smart battery with a quick glance and once the battery level gets low, an alarm will sound.(Smart ESC, Smart Battery and Smart compatible receiver required)
