RE: Batteries, what the?
Thanks everyone, really good info!
This was happening on a batt that I'd had for a while, and I thought maybe the battery was fried or just bad. I'd bought a brand new one, "formed" it, watching the temperature, and even that one was doing the same thing. I totally agree with Tom's advice, not "trying" additional flightsforget the fact that I really like the plane, it's just not plane safe (pun intended).
The first battery I know was probably bad because I'd had it for a while and did more quick charges than I should I'm sure. I'm going to continue to get another new one, and keep the current one if for nothing else as a backup.
PS, I will say that as a few of you have pointed out, I suspected the wall charger I have just wasn't enough, so I set up my field charger to charge at 200-300. The result was the same. Cycled it. Same thing...
