One thing that has changed over the last number of years is how you configure your receiver and transmitter to work with each other. Initially you needed to make sure each was on the same frequency by installing a crystal into each. That was improved upon when synthesized radios and receivers provided all the frequencies in the specific band in one package. Spektrum DSM technology is the next step in this evolution. To get a receiver and transmitter to work together you must perform a binding process. Many of us take binding for granted after having done it for as long as we have, but if you've never done it before you may have some questions. We've gathered a number of different DSM and DSM2 receivers to demonstrate the binding process in the video below. In addition to showing you how to bind your receiver we're also going to cover how to set your failsafe as well. We're also hoping to answer a few common questions regarding the binding process and why it's even necessary.



What Is Binding?

Binding is the process of training the transmitter and receiver to communicate with each other. Each radio and receiver have a unique code, called a GUID (Global Unique Identification Code) Code. This is your radio system's thumbprint that prevents it from interfering with other radio systems or being interfered with by other radio systems.

How Often Is Binding Necessary?

Anytime you purchase a new receiver it will need to be bound to your radio. Also if you are transferring a receiver from one car or truck to another and entering that model into a new model location you will need to re-bind it due to ModelMatch.

What Is ModelMatch?

ModelMatch is an exclusive Spektrum feature that prevents the radio system from operating if the incorrect model profile is selected from the model select screen. Each model location is given a secondary code on top of the GUID coding that mates that receiver to that specific memory location. If that code is not found the ESC will not recognize the transmitter, remaining in the failsafe mode. Both the DX3S and DX3R surface transmitters feature ModelMatch.

What Is a Failsafe?

A failsafe is a safety feature designed into Spektrum receivers that drives the servo or ESC positions to a preset location in the event that signal is lost. Typically you should set the failsafe so that if there is a loss of signal, full brakes are applied. This will help prevent runaways and possible damage or harm to those around you.

What Receivers Are Compatible With My Particular Radio System?

This multi-answer question is all-dependant on what radio system you have. First of all, you can only use surface receivers with surface radios; the air receivers are not compatible with the surface systems and vice versa. Secondly, you need to know what transmitter you have. Please see the matrix below to determine what receivers will work with your particular radio system.

Can I Use the Losi MRX-3000 Receiver With a Spektrum Transmitter?

Absolutely! The Losi MRX-3000 is completely compatible with all Spektrum Surface radio systems.
