The ergonomic design of the DX3™ transmitter provides a feel that any driver will appreciate. Its overall low weight allows all-day driving with minimal fatigue. The control layout is amazingly intuitive — the servo reversing switches, steering and throttle trim dials, AVC/steering rate dial and 3-position throttle limiter are all perfectly positioned to be quickly accessible when needed and out of the way when not in use. An easy to grip, foam-covered steering wheel also contributes to exceptional comfort and precise control that all surface modelers will enjoy.


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 don't want the extra traction, just dial back the stability and get loose. The DX3 transmitter's 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)

Does this have active vehicle control?
Asked by Levi on 26th April 2020

No, you'd need an AVC receiver for that.

Hi, is there any Spectrum transmitter that allows me to add to receiver so it would display 6v Battery hump voltage & speed of my HPI Savage Nitro truck please or is the Spektrum Smart Technology Just for electric models please?
Asked by Adrian on 12th January 2021

The SPM5120 comes with the SPMSR6100AT receiver which will measure voltage.

Speed is a bit trickier. You can measure speed however with something like SCH-SK-500023
