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!
Great transmitter! My favorite one I've ever used. I feel like I have great control and a good grip on it every time I've used it!
Bought 3 of these so far and they work great. Easy to set up and use, seems to be durable.
Super good radio for the money simple to use binding is very is done to thank aton amain
Most reviewers rate the Spektrum DX3 Smart 3-Channel DSMR transmitter with SR315 receiver very highly, praising its comfortable grip, easy setup and binding, smooth operation, and value, with several noting it works well in RTR kits and boats. One reviewer highlights the AVC assisted driving system as a standout feature. Shipping and service from the seller are frequently praised. Two low ratings report problems: one buyer had not received the product, and another said the steering switch broke internally after a short time of use in a Slash, describing a repeated failure in Spektrum controllers. One reviewer also reported difficulty using a Bluetooth module with phone apps. Overall the feedback is strongly positive, but the small number of reports of internal switch failure is a notable concern.
