Eliminate clutter and improve your RF performance with the SR2100 DSMR® Micro Race Antenna-Less receiver. The SR2100 features the signal performance you demand while making installing your receiver in a car or truck easier than ever. The Frequency-Agile DSMR technology delivers a super-fast 5.5m/s frame rate in even the noisiest of RF environments.

While small in size the SR2100 is packed full of features. The three-channel design makes it easy to connect your servos, ESCs, transponders, fans or other accessories. Binding to your DSMR-equipped transmitter, such as the DX6R, DX5C, DX5R, and DX4R PRO, is easy thanks to the integrated bind button.
