Been using ArduCopter 3.1 and i must say that i love the precision of altitude hold mode, the new drift mode and the ROCK solid loiter. So I just wanted to send a personal thanks to all the developers who made this possible.
I shot this entire video the last two days using many of the said modes. All i can say you developers ROCK!
PS: i can't wait till 3.2 beta to try out the David Dewey addition of 'SplineNav' mode! Looking way forward to that.
Cheers to all Ardupilots.
