I usually fly to the 30% warning mark and then prepare to land, usually landing at 25% or more. This gives me a bit to play with should there be any last minute change of plan, perhaps unforeseen wind etc. In saying that I'm usually within direct eye contact, so at most about 500-600 metres away.
The guide is to drain them too about 8% every 20 flights or so, this helps calibrate the 'intelligent' battery. To drain the battery you could let it hover just above ground until it auto lands at 10%, and lose the last couple of percent by powering it up and sitting idle. Let the battery cool, and then recharge. |
