Low Votage Cutoff (LVC)
http://www.rcgroups.com/forums/showp...68&postcount=1 (everydayflyer)
To rough check the LVC setting you are using, if the voltage is less than 3.7V/cell 20 min after flying, increase the LVC setting. If it is above 3.7V, decrease the LVC setting or leave it where it is if you are happy with the flight time. This is a rough check and you'll need to check pack temperature and capacity used to make sure the LVC is not set to low.
