I'm asuming it's going into a nitro. If that's true, just plug your battery into the Throttle (THR) slot and and then put the bind plug into the bind slot. Put your DX3R on the model you want and then turn on the battery in your car until the light in your reciever blinks rapidly. Next, scroll down to bind on your radio and select it. It should take a few seconds then the light on you reciever will shut off then come back on solid. You should now be ready to go! You can now take the bind plug out and reconnect your battery to the bat/bind slot and reconnect your servos.

If you have any more ?'s, you can post or pm me.

Ps, Hope it helps!
