You guys want a lot more time. None of you should expect a 5+ min time with a 150 mah pack, it just doesnt make sence. The only reason you are using it is because it is lite and that is the type of equipmnt the Fly needs.
I just found out, from some calls I made, that Energy Sales( http://www.energy-sales.com/lithiumpolymer.html
) sells Ultralife( http://www.ultralifebatteries.com/pr...play.asp?ID=39
)Lithium Polymer Battery packs(7.6 volts per 2 cell pack) that have a 530 mah capacity. The best part is each cell only weighs 15 grams!!!
You can contact Energy Sales at 1 800 96 ENERGY
This is going from what the guy told me, but he said that a person previously purchased five 7.6 volt, 530 mah paks for 38 a piece.
