One of the most common questions Spektrum receives is, "Why do your full-range DSM2™ aircraft systems have multiple receivers?" The technical answer is "path diversity," which we explore in more detail here, but a far simpler one is, "Why not take advantage of the redundancy and added safety that multiple receivers can give your pride and joy, even if you are using a state-of-the-art 2.4GHz system?" Especially if the receivers, like Spektrum receivers, are small enough and light enough that they don't add any unnecessary weight.

Redundancy, however, is but one of three big benefits Spektrum path diversity offers. The following diagrams explain how this path diversity (MultiLink) has solved two far more technical problems. Problems, by the way, that are faced by all 2.4GHz spread spectrum aircraft systems, be they frequency hopping or direct sequence. Only Spektrum's patented MultiLink solution has proven itself consistently, for years, to work where it matters mostin the field.

 

 

 

ServoSync™ is an ingenious DSM2 feature that automatically re-sequences the bits of data being transmitted based on the type of mixing you select.* For instance, if you select dual elevator mixing or 3-servo CCPM, ServoSync will see to it that those servos working together receive their pulses together. The result is more synchronized servo movement, which translates into an undeniable, locked-in feel when you fly.

*ServoSync is only available on transmitters with built-in DSM2 technology

 

 

Spektrum Pro Series modules and receivers offer performance enthusiasts the speed, durability, and precision that is necessary to win at all levels. A special conformal coating, called ReliaKote, has been designed for the receivers, along with all-new cases. These updates make Spektrum Pro Series receivers both water and fuel resistant. Another update that debuted in the Pro Series receivers and that since has been incorporated into the Original Series receivers is updated firmware that eliminates the possibility of an Electro-Static Discharge (ESD), sending the receiver into Fail-Safe mode when racing on carpet. Finally, for those looking for the smallest receiver possible, a new SR3500 Micro Receiver has been developed. Weighing in at a scant 6.5 grams and measuring just 1.06 x .78 x .48 inches, the SR3500 is perfect combination of performance and reliability in a miniscule package. All the SR3500 Micro Receiver's features are identical to the Spektrum Pro series receivers, minus telemetry capability.

Racers who equip their vehicles with Spektrum equipment can take advantage of real-time telemetry for the ultimate competitive edge. With Spektrum Telemetry Modules, racers can keep track of RPM, voltage, signal strength, and temperature all from the convenience of the hand-held unit. The addition of the Telemetry modules to any racecar will make testing even more valuable and provide more relevant data. For nitro racers, your pit man can now make the appropriate carburetor changes on the fly thanks to knowing exactly what the running temperature of the head is.
