How to bind a 2.4GHz rc transmitter and receiver

techtips10All 2.4GHz radio systems need an rc transmitter and receiver that are paired, or bound, so that the receiver can process signals from the transmitter.  This is what allows you to control your truck, boat, or other vehicle. Fancier radios also feature multiple model memory so you can just flip a switch to drive a new model with it and not have to reset all the basic radio switches such as the trims.

Even if you’ve got a vehicle that runs a 2.4GHz system, you might not yet have had to deal with the binding process.  The reason is that when you purchase ready-to-run electric kits, the binding process has already been done for you at the factory.  However, if you later need to replace your receiver or decide to upgrade the radio you will need to be able to bind your receiver and radio.  Luckily, the binding process is easy!

QUICK AND EASY STEPS FOR BINDING 2.4GHz RADIOS AND RECEIVERS:

Step 1.  Turn the receiver on in bind mode.

Step 2.  Turn the transmitter on in bind mode.

Step 3.  Confirm successful binding.

There are generally two methods for binding 2.4GHz receivers and transmitters: the cable method and the button method.  Older receivers will tend to require a binding cable while many newer ones can be bound just by pushing a button. In either case, there are two key steps for the binding process.  First, activate the receiver in bind mode.  Second, turn on the transmitter in its bind mode.  The rest should take care of itself, assuming you have compatible transmitter and receiver components.

How you activate the receiver binding mode depends on the type of receiver you have.  First install the new receiver into your truck.  For receivers that require a binding cable, you need to plug this cable into a receiver channel that is available for binding.  Next, turn on the car.  For receivers that have a bind button, you will need to hold the bind button down as you turn on the truck.  No matter the type of 2.4GHz receiver, watch for a quickly flashing light.  The quickly flashing LED signals that the receiver is in bind mode.  In binding mode, the LED flashes faster than it does when the receiver is simply not picking up a radio signal (perhaps because someone forgot to turn it on).

Activating the handset in bind mode is similar for most, if not all, types of rc transmitters.  Your radio will also have a bind button.  Check the user manual to see where it is for your specific model if you aren’t sure how to find it.  Next, simply hold the bind button down as you turn on the radio.  The radio and receiver should then bind immediately.  If the quickly flashing receiver LED switches to a solid color, then the binding has been successful.

The final proof of successful binding is whether the transmitter controls your truck!  Turn off the truck and radio and remove the binding cable from the receiver (if applicable).  Next, turn them back on as usual.  Turn on the truck first, then the transmitter.  If the truck responds to steering and throttle input, all is good.

As with all things, despite the best of intentions sometimes things do not go as planned with the pairing process.  Hence, we offer these three troubleshooting tips.

TROUBLESHOOTING TIPS FOR BINDING 2.4GHz RC SYSTEMS:

Tip 1.  Make sure the rc transmitter and receiver are compatible.  Different brand radios and receivers may not be cross-compatible.

Tip 2.  Make sure you are turning the receiver on in bind mode.  Watch for a quickly vs. slowly flashing light on the receiver.

Tip 3.  Do not delay too long in activating the radio in bind mode once the receiver has been turned on in bind mode.  A delay of five seconds or more could result in nonbinding.  If this happens, just shut everything off and try again.
