JR and Spektrum use the same technology, so a Spektrum AR9000 and a JR 921 are the same, as an example.
Once you Bind a Tx to an Rx, it does not "Lose it's Bind". The "Link" between the Tx and Rx can be broken due to a loss of Signal. It is restored when the Signal returns.
I dont see how you can make a blanket statment that a receiver does not lose it's bind when there
are many many reports of JR/Spektrum receivers that loose their bind.
I can understand that your receivers may have never lost their bind on their own but that in no way
means it can't happen.
