Tom: Agree 100%. If one uses an older technology (if there is such a thing) 2.4GHz system that has not been updated to eliminate (well, lessen the effects) of so-called brown out, if it goes to the red, the voltage is falling below the threshold and could cause the receiver to go into the dead zone until it resets itself. If this happnes during a critical time of flight, well the results are predictable.

This is not the first time this subject has come up, although it may be for the "volt-spy" device, it certainly has come up when debating the Voltwatch and during discussions about using loaded voltmeters. I can assure you that it won't be the last time the subject comes up.

To me, and obviously to most of the experenced pilots, it's an important subject and new pilots should get the basic understanding that one should check batteries. The device one uses is up to the individual, but the barest minimum would be a loaded voltmeter. I choose a loaded voltmeter and a back-up method called voltwatch2.
