Thanks for the suggestions.

I haven't noticed the blue LEDblinking when the battery gets low, but I'll keep an eye on that. The heli doesn't just fall out of the sky when the battery dies though, it just goes crazy (lol). The main thing that worries me is that the throttle sticks, so if the heli falls on its side the the blades will get stuck, which may burn up the motor or PCB. There's nothing I can do to stop the throttle when this occurs, so Ihave to quickly get to the heli and physically unplug the battery.

I suspected that I may have to start timing my sessions to prevent this from happening. I'm just a little disappointed there, because I'd really want to get the most out of the battery. I have a few more batteries on the way, so this will help. If Ican keep at least two of them charged, I'll get a little more flight time.

EDIT* I have an android phone (Samsung Galaxy S2), so Idownloaded a stopwatch app to use. It seems you were right on the money with the flight time. I got 7 min and 45 seconds before the battery died. From now on, I'll just stop at 7 minutes even to prevent the heli from crashing uncontrollably.
