Spektrum DX4R Pro 4Ch DSMR Racing System

The lightweight Spektrum DX4R PRO was conceived by racers for racers to deliver the same championship-winning response as the DX3R PRO*, but with the extra range and signal security of frequency-agile DSMR™ technology. It also features an impressive selection of available mixes, including pre-set mixes like MOA and 4WS, which can be switch activated and adjusted on the fly.

To this potent combination it adds new ergonomic features that have been designed specifically with long mains in mind. Almost every contact point you have with the transmitter can be adjusted for your comfort and driving style, including the shape of the trigger.

The Spektrum DX4R PRO includes the SR2000 DSMR™ micro race receiver and a FREE SR410 4-channel DSMR™ sport receiver.
