A simple to grip, foam-covered wheel also adds to remarkable convenience and precise control that all surface area modelers will enjoy.





DSMR TECHNOLOGY

DSMR® TECHNOLOGY
The DX3™ transmitter is constructed around proven Spektrum™ DSMR® 2.4GHz frequency-agile technology. The variety and response of DSMR technology is exceptional, particularly in loud 2.4GHz environments. It can utilized with any surface area application and is backwards-compatible with Spektrum DSM2® receivers.
 

AVC (ACTIVE VEHICLE CONTROL)

AVC® (ACTIVE VEHICLE CONTROL®)
The DX3™ radio system supports the on-demand traction control of Spektrum™ AVC® (Active Automobile Control®) technology.
