I've got mine set at 10.8 and 10.4 ... Usually get around 10 -12mins fly time depending how windy it is but that's with nothing on the bird ...if I'm using fpv and carrying the gopro I set the timer to 8 mins and bring it home when it goes off just to be on the safe side and to date it's not dropped out the sky... The battery usually reads 11.2-11.4 after use .
