Smart Technology ensures that all of your model's electronics work together seamlessly for the greatest efficiency and performance. It makes your entire system more responsive and simpler to use.



The DX5 Pro 2021 features Spektrum's latest RF module, engineered around DSMR 2.4GHz technology. This generates a stronger and more robust signal, increases the telemetry range, and creates an extremely reliable connection between the transmitter and receiver. When paired with a receiver capable of 5.5ms frame rates, such as the SR2100, the DX5 Pro 2021 delivers lightning-fast response that gives new meaning to the word "connected".



The ergonomically designed DX5 transmitter has a feel that any driver can appreciate. Its overall low weight minimizes fatigue, while the non-slip rubber grip and trigger-throttle action deliver precise control that feels perfectly natural. To these, the updated DX5 Pro 2021 transmitter adds a new steering wheel mechanism that increases the accuracy and precision of steering motion.



Among the many ergonomic options available for tailoring the DX5 Pro 2021 transmitter to your personal touch are updated trim tabs, designed to make their operation easier while you drive your vehicle.



The DX5 Pro 2021 offers an impressive number of programming features — and they're easy for anyone to use, thanks to the SimpleScroll programming interface that makes navigating menus and changing settings as simple as "scroll and click". You can program up to five drive modes per model to help dial in the perfect drag racing and lap times. Drive modes can also be used to program compatible AVC (Active Vehicle Control) receivers to match your skill level, driving style, and terrain to provide predictable handling at every speed. There are multiple mixing setups, including Motor-On-Axle (MOA), plus ABS, Traction Control and 4-wheel steering, dual rates, expo and more.



You can select from a variety of vibe alerts for timer alarms, low battery voltage and other telemetry functions. Most of these can be set to go off when the voltage level or telemetry data exceeds specific values that you can easily define in the telemetry menus.

Spektrum RC DX5 Pro 2021 5-Channel DSMR Surface Radio (Transmitter Only)
I do not understand why the battery door is locked with screws, this is very inconvenient because I use batteries and change them every day! When I opened the battery door for the first time, I lost all the screws, I will never buy a Spectrum Pro version again ...

Cheap plastic feel with self tapping screws. The battery cover is held on by two self tapping screws making it difficult to change the batteries.

Spektrum RC DX5 Pro 2021 5-Channel DSMR Surface Radio (Transmitter Only)
The transmitter works well and smart telemetry works.

The battery setup is terrible.the battery cover is screwed down with two hex bolts and there is no latch.

I would be fine with this if the batteries were rechargeable lipo, but they are instead 4 AA. They go dead quickly and you need tools to change them.

There is a 2S lipo pack available and the transmitter can be switched to support lipo batteries in the display settings. The thing is there is no charge port so you have to unscrew the battery cover and unplug the pack and plug it into an adapter then plug the adapter into your charger.

The DX6r transmitter has a charging dock and a lipo battery. My cordless phone from the 2000s had a better battery system than this transmitter and it would be 20 years old now. Any cell phone i have ever used has a better battery system than this transmitter. I am not sure why they made it so substandard.
