Overview: The DX3 is much more than an economical 3-channel remote control. Together with the included SR315 receiver, it is the most affordable remote control system that offers the superior range, responsiveness, and interference resistance of the exclusive Spektrum DSMR technology. Additionally, drivers using the DX3 can enjoy the innovative Spektrum Smart technology. By installing a Spektrum Smart LiPo and Smart Firma ESC in your vehicle, you can view the vehicle battery capacity at a glance on the convenient voltage display of the DX3 transmitter. Equip your DX3 with the optional Bluetooth module BT2000 and download the free Spektrum Dashboard app to your smartphone. You can also use Smart real-time telemetry - without any built-in sensors or modules.
