RE: does everyone here use lipo?
Not in my bigger/glow conversions I use A123s!
Cans not bags and much more tollerant to our kind of use.
Also, they can be recharge very quickly while in the plane, and only need a "balance" once in a while.
I either use my 5020 MasTech Power supply @ 20amps; or "Zip" charge: 1 Pb = 3S, 2 Pb = 6S (my .46s), 3Pb 9/10S (1/4 Cub & Groovey).
