Duplicate or Eliminate any single point failure.
Good advice.
In one instance the battery connection came loose in the pack, and in the other instance a single reciever went into failsafe and the plane was landed on the other receiver.
How is this possible?? PCM failsafe on one RX but not the other?? How can one RX get interference, but not the other?? Either they are getting a good signal or they are not. I cannot see how one can and the other can't. I suspect something happened to the other RX and that it did not, in fact, go into true failsafe.
Yes you can, if wired properly, make a single pack/switch/reg provide enough current, and will probably never fail. But it is then a single point failure.
Remember, the TX is ALSO a single failure point. Oddly enough I have NEVER had a modern RX fail on me, but I have had THREE TXs die on me. All on the ground, but I have seen TX failures in flight too. Not pretty. Redundant TXs anyone??
