Randy....
Thanks for Pointing that Out......
You are Right....Failsafes DO work when your Receiver Batteries are Low, (at least,they Should...

).
When we were shooting that Video,,,,I Had it in my Mind to talk about what would happen if a Battery were to Pop Out of the Receiver Brick.....
In THAT case, the Failsafe would be useless.....I got my Dialog Mixed Up.....
That's what Happens when I try to Talk and Chew Gum at the same Time...
