Hey deluge2 and ProPilotWannaBe, thanks! So much to shoot... so little time.
hehe
I hope to shoot some more next weekend.
I have a battery warning at 21.8v which vibrates my radio. At that point I fly home and land. My next and final warning is at 20.0v. On this warning the S800 just lands itself, autonomously, wherever it is. The reasoning behind it is that the battery will die any second, so it is better to attempt a landing rather than fall out of the sky!
On this occasion what I did was fly it home on the first warning, but let it hover about 3m above the ground until the second warning, at which point it landed itself. At that point it had been in the air for 13min.
Generally I get 10min practical air time and as soon as I get the first vibration warning I come home.
I hope that makes sense.
Steve
