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 reveiver 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 PRO, DX4R PRO and DX4S, is easy thanks to the integrated bind button. Plus, you get the extra protection of a waterproof‡ Reliakote™ conformal coating that seals its electronics from the elements and other corrosives like nitro methane or motor spray.

† Requires a DSM2/DSMR transmitter capable of a 5.5ms frame rate.

‡ For complete details on waterproof standards, please refer to the product instruction manual.

Love these receivers, and the fact you don't have to worry about an antenna. It has worked with out any faults. A purchase well spent.

I could be crazy, but his Rx feels faster than the SR215 DSMR Sport Rx.. They spec out near the same, but I just feel more confident and connected with the SR2100. Could very well may be placebo, but still worth the extra money to me, especially when it means I no longer have to show my Tx to prove AVC is off.
