I sure know, Acebird. I said in the earlier post how my batt once died on me in flight. It worked fine and in much less than a minute it would not do anything! It just sat and circled (luckily at idle) and the servos would not move at all. The time span from a noticable drop in response to none was seconds. Then I saw articles showing the curve...almost level then- thud- right to nothing! That is why I got a field charger, cause I probably say no go when there are several flights left in the pack. I see the ESV get down to the bottom half of the range between go/no go and I stop. Of course, now that I have a quick field peak charger I am looking foreward to finding the exact flight time and capacity monitoring... even knowing when packs are too tired to keep.
I think your idea of loading the monitor is great. I know when I was new I read on a forum to buy a ESV with a load instead of using my Fluke, or to put a load on the batts.
Happy flying!
