Really sounds to me like you need to update the receivers. And just to make sure, here's a quick run down on how to do so.
First, make sure your receiver has a binding plug plugged in the update way (not sure what they call this). Its plugged in perpendicular to what you would normally do, and on the bind end. See the pic here:
After plugging the binding plug in this way, power the receiver on.
Then turn on your Noble, and go to "RX SET", shown here in the bottom left.
Then scroll all the way down and select "Update Receiver"
Then select what receiver you are using. And click "Update"
This should be it. You'll then see a progress bar and the radio will notify you when its done.
After that, turn off the receiver, rotate the binding plug to the "normal" way, in the bind port, and bind the radio.
I can make a more detailed explanation of that as well if needed. But its pretty much the same thing, binding plug in, power on receiver, "RX SET", "Bind With A Receiver", done.
