Just yestarday i was sitting on my couch with my heli shelf located on teh wall behind me and I heard this buzzing sound. i checked it out and it turns out it was my CX2's servo in a death throw. I had left the lipo plugged in for more than 24 hrs. The red light was on and it wouldn;t even sink to my radio at all. The battery was 100% depleted. I took it out and plugged it into the charger but of course the light just blinked green. Great, I wasted one of my batteries so I tossed it into the recycling bin. A couple hours later I tried it again and this time it took a charge, not only that but it didn't seem to effect the life much at all. I can still get about 10 mins out of it. Sort of off topic but I thought I would share.
