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)



This Spektrum DX3 Smart 3-channel transmitter with SR315 receiver is compatible with Arrma 1/5 scale Kraton 4X4 8S BLX brushless speed Monster Truck RTR by Arrma.
