Ok, I went back and read some of the comments. If your battery is falling to .3 v I think the battery is bad. I use a 1.2 v 1200 mah battery that comes with the rechargable battery set from Sams, Wal-Mart, Best Buy, Circuit City or who ever, and I get about 6 flights before I change the battery out. I don't know if the fact that I'm starting 4 strokes is part of the reason because I've heard that 2 strokes aren't good upside down but I was also told you have to run 4 strokes with a remote glow that is on during low power which is not true. I think the 2 stroke would flood the glow plug easier.
