Matt,

You are right, I'm running Ed's IBEC's and couldn't be happier with it. I usually stop flying at around 7.5 under load also, however on my old Li-Ion they always said the no fly voltage was 6.9 although I never went that low. I have dual 900mah LiPo packs that I run, and I can comfortably get 4 flights in one day and only put about 400-450 back in each pack, so I'm using around 200-225mah per flight (10 minutes of flying), this includes the ignition, RX, and servos..
