Spektrum SR515 5-Channel 2.4GHz DSMR RC Sport Receiver: Surface , Black

Compact, Full-Range RC Receiver
Built around frequency-agile DSMR technology, the latest Surface receivers deliver superb range and response, especially in noisy RF environments where a solid 2.4GHz link is crucial. Not only is the 2.4GHz link solid, this latest offering also provides our lightning fast 5.5ms frame rate, providing a quicker and less latent connection for the pro-level enthusiast. These receivers also feature a new, modern case design that is small, streamlined, and ready for nearly any RC application.
The case features added antenna support and an integrated antenna tube slot for seamlessly easy installation. No more bind plugs! Instead, an easy to use bind button is used to enter the bind mode. Plus, while binding, you have the choice of SmartSafe as well as preset "Gas" failsafe options.
All combined, Spektrum gives you more in a basic receiver, so that you can drive with the highest sense of confidence possible and have more fun.
