The Spektrum SR315 3-Channel DSMR Sport Surface Receiver is built around frequency-agile DSMR technology. The SR315 receiver delivers 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 model also implements lightning fast 5.5ms frame rate, providing a quicker, low-latency connection for the pro-level enthusiast.

The SR315 also features a modern case design that is small, streamlined, and ready for nearly any RC application. The case also 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 drivers more features in an affordable receiver, so you can drive with confidence.

Compact Design
The SR315 is capable of being placed in very small and tight builds. Unnecessary angles were eliminated to streamline the receiver casing and to make installation easier than ever before. The case also features added antenna support and an integrated antenna tube slot for those custom models that do not provide a route for the antenna installation.

Bind Button
Updated technology eliminates the need for the old bind plug. With The SR315 a top-located button makes binding more convenient than ever while two bind-sequence options make the process simpler by allowing you to bind while powering up or after receiver power is connected.

Gas Mode Failsafe
Built into The SR315 is Spektrum's failsafe mode for surface applications, Gas Mode Failsafe. Easily selectable during binding, Gas Mode allows users to preset the failsafe position of all available channels. Additionally drivers can utilize SmartSafe ™ failsafe which drops throttle to the lowest point and holds the last known command on the rest of the available channels.

  • Bind-button eliminates the need for a bind plug
  • SmartSafe™ Failsafe and Preset "Gas Mode" Failsafe options

Spektrum RC SR315 3-Channel DSMR Sport Surface Receiver
Works great, no problems at all. Already had an SR310 as that's what came with my Losi RTR nitro buggy that I took my electronics from for my Tekno nitro buggy. The SR310 worked fine and didn't give me any trouble, so when I got a Tekno ebuggy, I figured I'd get another SR310. Turns out that was discontinued and replaced with this SR315. No big deal, seems like it ought to only be as good or better. Well, that's exactly how it turned out -- the SR315 has performed flawlessly for me, and even surprised me with a voltage meter appearing on the screen of my DX5C radio for the Rx when I have my ebuggy selected and powered on (that space on the screen is blank when driving the nitro buggy that still has the old SR310). I rarely ever bind receivers since I don't change radio equipment often, but that's still nice having the button rather than the bind plug. Of course I wish the price was a bit lower but I suppose I can live with it given how well it's worked. I will buy another if I add an additional RC car to my fleet.

Pros: No more bind plug/connector. One button bind is life-changing.

Cons: I ran a Spektrum DX3R receiver and had some initial issues with the setup but was eventually able to pair it with my receiver.

Recommendation: None.

After a little dust got in my receiver box it started to glitch, second spektrum receiver in a month with defects. Probably have to stick to the 2 channel instead, spending to much money and things don’t work after two weeks. Not cool.
