DarkWombat,

Hehe indeed, I've just done this. I bought a 20C 400mAH cell and a 10C 850mAH cell (PolyQuest) and just today got to test both out. OH WOW! is all I can say for the 400. My BCP nearly came off the ground when I centered my throttle trim. It flew incredibly well and made my BCP feel as if it had no inertia (as compared to the 1320 anyway). I know this will be my performance battery -- even tho its only good for one flight.

I was so impressed with the extra responsiveness and control that I even took my training gear off for the first time since my fateful 1st flight hehe.. The 850 is only about 12 or 13g lighter than the 1320 cell, but having a second (semi) long-durration battery is welcome. The 400, weighing in at only 45g, is simply incredible.. just awesome. I think I'll pick up a few more of these suckers hehe.

Oh, and that's too bad about your 1320 overdischarging -- saionara $50 . I've been careful not to do that to mine by checking the voltage from time to time and learning to identify the "land now" performance drop. I fly for no more than 3 minutes per flight on average, which I do mostly to let my main motor cool down (think I'll take your 8t 370 motor advice! heh). I noticed my BCP loses the will to fly quite suddenly when the LiPo cell gets low. As soon as I perceive that, it's the end of the flight -- period -- and so far, no battery failures...... jynx
