You asked and NJSwede provides:
Shady is 100% right. If the rx doesn't detect a signal on startup, it immediately goes into binding mode. If it has a signal, it just keeps on using it. So it's a little different from how the full size rxs work.
But now that I know how it works, I won't have to rebind all the time. Thanks Shady!
