The problem with receiver voltage telemetry is the same as the problem with the good old Voltwatch, false warnings. There is no substitute for a proper load test on the ground. In over 23 years of flying RC, I've never lost a plane to low receiver batteries (Now I've done it, jinxed myself for sure[
]). Many of us are now running A123 cells, so the telemetry would be truly useless,
The one telemetry use that really is snake oil as far as I see it, is a fuel level readout, not the way I fly
.
I cannot see how one of those level systems can equal the accuracy of a throttle activated timer in actual use. I establish a safe flight time for each model and land when the time is up. As the saying goes, "works fine, lasts a long time"
I think that the folks that are being perceived as negative on telemetry are just being realistic, rather than trying to rain on your parade
