• Built-in Telemetry System — Integrated telemetry capabilities provide real-time feedback on system status when used with compatible Smart Technology components, keeping you informed about critical parameters during operation.
• Programmable Vibe Alerts — Select from a variety of programmable vibration alerts for timer alarms, low battery voltage warnings and other telemetry functions. Most alerts can be customised to trigger when voltage levels or telemetry data exceed values you define in the telemetry menus, ensuring you never miss critical information.
• 250-Model Memory — Store programming profiles for up to 250 different models, making the DX5 Pro ideal for pilots with extensive RC collections or those who support multiple models during club racing events.
• LiPo Battery Compatible — The transmitter supports LiPo battery packs in addition to standard AA alkaline or NiMH batteries, giving you the flexibility to choose the power source that best suits your needs and driving habits.
• Launch Control Mode for Drag Racing — Available with Raceware firmware V2.02 or higher, the dedicated Launch Control menu is specifically designed for drag racing enthusiasts. This feature allows you to control the duration of throttle ramp-up and adjust points in the throttle curve, enabling precise control over how quickly your model reaches full power so you can focus entirely on steering your model straight to victory.
• Dual Protocol Compatibility with Firmware Update — With a firmware update, this DSMR transmitter becomes compatible with SLT protocol-equipped vehicles such as Losi NASCAR RC Racecars, ARRMA GROM small-scale bashers and Axial SCX24 micro crawlers, allowing you to operate both SLT and DSMR protocol receivers with a single transmitter.
• Ergonomic Design with Updated Steering Wheel Mechanism — The redesigned steering wheel mechanism increases accuracy and precision of steering motion, whilst the overall lightweight design minimises hand and arm fatigue during extended sessions. Updated trim tabs are engineered for easier operation whilst you drive your vehicle.
• Firmware Update Capable — The transmitter is equipped with SD card compatibility and Airware capability, allowing you to receive firmware updates that improve operation and performance whilst adding new features and benefits over time.

Technical Performance

The DX5 Pro 2021 is engineered with professional-grade precision throughout its construction. Measuring 211mm in length, 142mm in width and 135mm in height, the transmitter features a compact yet ergonomic footprint that fits naturally in your hands whether you're a small-framed racer or an adult enthusiast. At just 0.63kg, the lightweight design ensures minimal fatigue during marathon racing sessions or weekend bashing adventures. The transmitter accepts power from either four AA batteries (alkaline or NiMH) or a dedicated LiPo transmitter pack, providing flexibility in power source selection based on your usage patterns and performance requirements. The 2.4GHz DSMR RF module delivers exceptional range and signal integrity across the typical operating envelope of RC cars, boats and surface models, with the latest RF engineering ensuring robust connectivity even in environments with multiple radio sources. The 5.5-millisecond frame rate represents the gold standard for responsive control in surface RC applications, whilst the transmitter also supports 11ms, 16.5ms and 22ms frame rates for compatibility with a wide range of existing receivers. The 2048-point resolution provides extraordinarily fine control input granularity, translating stick movements into precise proportional commands with no perceptible dead zones.
