The Spektrum DX3 Smart 3-Channel DSMR Transmitter is more than an economical 3-channel transmitter. Together with the included SR315 receiver, it's the most affordable radio system that offers the superior range, response, and interference resistance of exclusive Spektrum DSMR technology. Plus, drivers using the DX3 are also equipped to enjoy the breakthroughs of innovative Spektrum Smart Technology.

Install a Spektrum Smart LiPo battery and Smart Firma™ ESC in your model, and you can view vehicle battery capacity at a glance on the DX3 transmitter's convenient voltage level indicator.

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).

Spektrum RC DX3 Smart 3-Channel DSMR Transmitter w/SR315 Receiver
I got this transmitter with the Super Baja Rey 2.0 and wasn't expecting much for an RTR set as most are dismissible rather quickly. But this DX3 and the receiver that was also included with the truck are a fantastic quality combo that outperforms other RTR options easily. I really don't see a need for upgrading anytime soon, and if I did I might actually consider sticking with Spektrum and just getting a DX5C. I have most of my other RCs on Flysky NB4 with their AFHDS3 receivers, which is a superior system to me on many levels, minus one important feature; AVC.

Spektrum nailed it with their assisted driving system. AVC blows the rest away, and I've tried as many as I could to compare. Radiolink, Flysky, Traxxas, and PowerHD gyros all do fine in one category but lack or completely fail in others. AVC no matter what it is dialed to, stays in composure and doesn't do any unpredictable tomfoolery. I've put this DX3/SR6100AT combo in a few other trucks to see how it works and its awesome in them all. I really don't rely on gyros when I am in full focus driving mode, but when I'm just cruising from one spot to the next its great to have. Honestly I've been very thankful in a few situations to have it on, it's corrected me on stupid mistakes that I would have never seen coming that could have been costly. The more expensive the RC, the more I find myself pretty happy to have the option of AVC (or any gyro at the least).

This transmitter is strong and has the basic settings you need to really just get out and drive. The range is further than I can see, it's comfortable to hold, lightweight, the wheel is a great size with nice foam. I converted mine to a Lipo/NiMH setup for recharge-ability and it works perfect with a 7.4v Lipo which is over the 6V operating voltage especially when fully charged (8.4v) but its worked fine for many hours. 6V NiMH recharge packs are all over the place to purchase that would work perfectly for this transmitter.

Good work Spektrum!

Honestly an amazing upgrade to any RTR, and a fan favorite. Seriously, this transmitter is extremely comfortable and feels great in the hand. coming with the 3-channel receiver, you are really only spending less than 50$ for the transmitter (when you subtract the $50+ for the DSMR receiver), and it is worth every penny!

I bought this radio because I already have one in my LOSI Lmt and Love it. I replaced the one from the CEN Racing Hl150 and plan on replacing my slt3 that is currently it my SMT10. It has great range and reaction time for my use. I really enjoy using this unit. And as usual A-main nailed it with fast shipping and great prices and service.

Spektrum RC DX3 Smart 3-Channel DSMR Transmitter w/SR315 Receiver
This has been one of the best transmitter and receivers I have used. I have only had it a week or so now and fully haven't experienced all it offers yet but still love it. The only issue is I bought the Bluetooth module at the same time but all of my phones "are to new" and can't download the dashboard app. Trying to figure it out and keep ya posted. Happy R'Cing everyone.

I give it no stars period . Garbage don't waste your money I'd didn't even last two batteries in my slash before it broke inside the switch for the steering snapped and no more steering and no way to fix it I will never buy a spectrum product again this is the third issue with their controllers they always break inside and don't say I'm too rough they sit on a shelf when not in use
