All that bind and rebind sort of thing is completely unnecessary when using Futaba and some other brands of equipment. The receiver remembers the failsafe settings as instructed by the transmitter during setup. Spektrum and some JR equipment does require the rebind where Futaba is link once and forget.
Even during the 72 MHz years, if the transmitter wasn't on first, electrical or random RF noise or even poor (but common) receiver decoder design could cause one or more servos to run to extreme when the receiver was turned. By turning the transmitter on first, proper decoder operation was assured and the servos and associated linkages and surfaces were happier and w/o damage.
