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.
I believe the receiver went bad don't know all the details, but it was sent back to the MFR and replaced.
Like I said before I have peace of mind with redunt packs, batteries, switches on my 28% and 33%, and redundant receivers as well on my 42%. I don't really care what the average current pull is. I fly and check my batteries under load after every flight. If I can get 10, 15 minute flights and still have safty margin I am totally happy. With $2000 to $7000 invested in each of my planes I am not taking any chances.
Duplicate or eliminate any single point failure.
