When you buy a new radio, the Rx is already bound to it. It is only when you buy a new Rx that you have to bind it to your current Tx.

It's been a while, so I forget the Spek binding process, (Maybe someone can help me out here) but I seem to remember having to hold a button on the Tx as you turn it on and the Rx has to be off, but plugged into a switch with a binding plug plugged into the charging jack?

One of you Spektrum guys help me out on this. What is the exact proceedure?
