Spektrum RC DX5 Pro DMSR Transmitters Spektrum RC DX5 Pro DMSR transmitters feature 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 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 transmitter adds a new steering wheel mechanism that increases the accuracy and precision of steering motion.The DX5 Pro 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.
