Overview

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 our lightning fast 5.5ms frame rate, providing a quicker , low-latency connection for the pro-level enthusiast.

The SR315 also features a new, 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. We eliminated un-needed angles 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

New 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 our newest failsafe mode for surface applications, Gas Mode Failsafe. Easyily 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.

Smart Technology Ready

The SR315 now comes updated and ready to provide the advantages of state-of-the-art connectivity right out of the box by supporting the innovative, all-in-one telemetry of Spektrum™ Smart batteries and ESCs. Smart Technology ensures that all of your vehicle's electronics work together seamlessly for the greatest efficiency and performance.

Traxxas Stability Management (TSM) Makes You Faster

Traxxas Stability Management^® (TSM) lets you experience all the extreme power, speed, and acceleration that was engineered into your Traxxas model by making it much easier to control on slippery surfaces such as loose dirt, smooth concrete, and even ice and snow. Go ahead, punch it off the line! TSM senses the vehicle’s direction and makes steering corrections to provide straight-ahead full-throttle acceleration without fishtailing or spinouts. When cornering, TSM intuitively corrects the vehicle’s line for faster exit speeds. TSM also improves braking by keeping the vehicle arrow straight until you reach a complete stop.

No Unwanted Side Effects or Disconnected Feel

TSM lets you enjoy all the benefits modern electronic stabilization without intruding on your driving fun or introducing unwanted side effects. Traxxas engineers developed superior tuning algorithms that run on high-speed, precision electronic components to create a system that works invisibly, in the background, without ever limiting your throttle. TSM delivers sharp and precise reactions, rather than a dull, disconnected feel. TSM can be fine-tuned (or turned off) for different surfaces by adjusting the multi-function knob on the TQi transmitter, or by adjusting the slider in the Traxxas link app. Drive faster, with more ease, and have more fun! In fact, you may not even realize how much TSM is helping you until you try to drive without it!

How Does TSM Work?

TSM lives in the receiver and works with TQi transmitters equipped with a Multi-Function knob. It does not require any additional setup or configuration from the driver. The Multi-Function knob adjusts the amount of assistance provided by TSM. More assistance tightens the control, virtually eliminating fishtailing and sliding. Less assistance allows the vehicle to be more loose for controlled power slides and “steering” with the throttle. TSM never restricts throttle input. The driver always has complete control of the power. TSM can easily be turned off by simply turning the multi-function knob counterclockwise to its stop. TSM can also be adjusted in the Traxxas Link application. The control icon is in the “Garage” in Traxxas Link and also the Drive Effects screen. Each model has a specific software load, custom tuned to the model. Traxxas Link remembers TSM setting when the driver uses the same transmitter and switches between various models equipped with TSM.

Have extra tires on hand!

While our mission at Traxxas is to build our vehicles tough to resist breakage and wear, if you like to pull the throttle trigger hard and often, expect some increased tire wear. Normally, without TSM, it can be difficult to hold full throttle for extended lengths of time, particularly when the vehicle is configured with brushless power and 3S LiPo batteries. Drivers naturally tend to back off the throttle to maintain control, which reduces tire wear. However, TSM opens the door for full throttle acceleration on practically any surface and simply-put, if you like to lay down the rubber, the tires don’t stand a chance. Keep an extra set handy, particularly if you’re driving on asphalt and concrete.

TSM on Other Traxxas Models
TSM is not just for land vehicles. It can be found in the Spartan and DCB M41 boats, making turning and full-throttle acceleration easier and more fun. Installation is possible on other Traxxas models using a TQi radio system with the Multi-Function knob and the Wireless Module (#6511). Connectivity to the Traxxas Link App (iOS or Android version) is also required in order to update the receiver with vehicle-specific firmware.

Key Features

Overview

The Futaba R203GF 3-Channel 2.4GHz S-FHSS Receiver is compatible with Futaba FHSS and S-FHSS transmitters. Futaba S-FHSS 2.4GHz receivers benefit from Futaba's patented Pre-Vision™ circuitry, which scans incoming data and corrects errors before they can become problems. They sync perfectly with Continuous Channel Shifting, handling hundreds of frequency changes per second with flawless precision. Plus, they all offer the Easy-Link™ advantage — the feature that allows the receiver to “learn” the transmitter module’s unique code with the push of a button and establish a unique, unbreakable bond between the two.

Frequency Hopping Spread Spectrum (FHSS) technology minimizes interference from other 2.4GHz systems. Easy Link prevents unwanted signal conflicts by using a special, pre-assigned ID code. High-voltage  operation.

NOTE: This receiver is NOT compatible with 2.4GHz FASST or FASSTest systems. It will work with FHSS and T-FHSS transmitters, but transmitter mode will need to be changed to from T-FHSS/FHSS to S-FHSS mode.

• T-FHSS SR (SUPER RESPONSE) AND TELEMETRY T-FHSS: In addition to the T-FHSS telemetry system, we added a T-FHSS SR (Super Response) system that increased processing speed to further improve response. SR system does not support telemetry function. *R304SB and R304SB-E are not compatible with SR system.
• T-FHSS MINIZ SYSTEM: By changing to the MINIZ system in the receiver setting menu, you can use Kyosho Mini – Z Evo dedicated receiver RA-42. Dedicated receiver RA-42 must be purchased separately.
• TELEMETRY SYSTEM: The T4PM transmitter has adopted the newly developed bidirectional communication system “T-FHSS”.
• 2.4 GHZ SS RADIO COMMUNICATION SYSTEM: Frequency channel setting is unnecessary: Channel shifting takes place within the 2.4 GHz band automatically. This system minimizes the interference from other 2.4 GHz systems.
• MODEL MEMORY FOR 40 MODELS: Model names can use up to 10 letters, numbers, and symbols, so that logical names may be used. A model memory with different setups can be created by using the model copy function.
• 4 AXIS JOG BUTTON: The (JOG) button can be operated in 4 directions: up, down, left, and right.
• ESC-LINK FUNCTION (MC-LINK): This dedicated function allows you set up the Link software so that your T4PM can control variable frequency and other data changes in Futaba speed controllers (ESCs): MC950CR, MC850C, MC851C, MC602C, MC402CR, etc.
• S.BUS SERVO: This is a special function that allows setting of the parameters of our S.Bus servo whose settings are changed by using PC Link software. In addition to the conventional wired system, it can be set wirelessly in combination with the R334SBS or R334SBS-E.
• STEERING MIXING: Smooth cornering is possible by independent left and right steering servo setting.
• BRAKE MIXING FOR LARGE CARS (BRAKE): Brake mixing of the front and rear wheel of 1/5 gas power cars and other large cars can be adjusted independently.
• GYRO MIXING (GYRO MIX): The sensitivity of Futaba car rate gyros can be adjusted from the T4PM.
• 4WS MIXING FOR CRAWLERS AND OTHER 4WS TYPE (4WS): This function can be used with crawlers and other 4WS type vehicles.
• DUAL ESCS MIXING FOR CRAWLERS CARS (DUAL ESC): ESCs at the front and rear are controlled independently.
• CPS-1 MIXING (CPS MIX): LED lighting and flashing control using our CPS-1 channel power switch can be matched to steering and throttle operation by switch only.
• ANTI-SKID BRAKING SYSTEM (TH A.B.S): This function applies the brakes so that the tires of gas powered cars, etc. do not lose their grip on the road even when braking at corners.
• THROTTLE ACCELERATION (ACCEL): Gas power cars have a time lag before the clutch and brakes become effective. The throttle acceleration function reduces this time lag.
• THROTTLE SPEED (SPEED): Sudden trigger operation on a slippery road surface will only cause the tires to spin and the model to not accelerate smoothly. By setting the throttle speed function, operation can be performed smoothly and easily. It also suppresses battery consumption.
• STEERING SPEED (SPEED): When you sense that the steering servo is too fast, etc., the servo operating speed (direction that suppresses the maximum speed) can be adjusted.
• RACING TIMER (TIMER): The lap timer can record 100 lap times and total time. The timer can also be started automatically by trigger operation. The race time and audible alarm can be set. Re-/fueling time are indicated by an audible alarm. An up timer is also provided.
• FUNCTION SELECT SWITCH (SWITCH)/DIAL FUNCTION (TRIM DIAL): This assigns functions to 2 switches and dials (digital trim, digital dial). The step amount and operating direction can also be adjusted. Trim positioning at each model call is unnecessary because all the dials are digital.
• TRIGGER POSITION CAN BE CHANGED: The position of the throttle trigger can be moved forward and backward.
• TENSION ADJUSTMENT FUNCTION: The tension of the steering wheel and throttle trigger springs can be adjusted from the outside.
• MECHANICAL ATL ADJUSTMENT: Make this adjustment when you want to decrease the total travel of the brake (push) side of the throttle trigger.

The ProTek R/C Receiver Voltage Stabilizer is a small but powerful super-capacitor that stores and releases power to ensure receiver voltage is always stable.

While a BEC regulates voltage to the receiver, it can't perform properly without enough available power. Sometimes a servo or high-power brushless system can draw large pulses of current making the voltage drop and unstable; the result can be glitching, sporadic servo, transponder or gyro performance. 

To combat this, the ProTek R/C Receiver Voltage Stabilizer stores and reserves extra power to be released during these drops. This not only helps reduce the load on the BEC, but ensures voltage remains stable and consistent to the vital components of your system.

The ProTek R/C Receiver Voltage Stabilizer comes pre-wired with leads and a standard receiver plug, ready to be installed into an open port on your receiver. It is compatible with any standard receiver and works with modern 2.4GHz radio systems, as well as legacy 27, 72 and 75mHz systems.
