Sorry, didn't mean to start an argument. Maybe my caution regarding
flying with R/C (foil bag) LiPo batteries is a little over the top. I
can live with erring on the side of caution. To each his own.

I'm not trying to get into an argument either, just making the point
that most of us already carry several foil bag lithium polymer batteries
in our gliders. The original metal case lithium ion batteries haven't
been used in consumer products for years, mostly because we want
everything light (remember 8 lb laptops?).

R/C batteries have a high (explosive 8^) failure rate mostly due to the
various kinds of abuse they are subject to, incorrect charging,
continued use after being damaged in crashes, overly high discharge
rates, full short circuits, etc. If someone knows what they are doing,
there shouldn't be a problem. But, I agree, if you don't know, don't do
it. I, for one, wouldn't want a pack large enough to power a radio and
transponder in my glider...
