I had one battery with the same issue, charge for about an hour and a half then the light would flash I would unplug then try again but then it took another hour and a half. For some odd reason now it works just fine, like it sorted itself out after a couple frustrating charges. Was very close to sending back to Parrot. I literally had a 2.0 battery get beaten by the 1.0 charger and battery.. Only thing I did was take off and reattach the adaptor plug on the charger.

Even though I have some concerns about the firmware issues I would still say go for it. I have had a blast flying mine and messing with the videos. They will fix the firmware stuff soon anyways. Like some other people have said, be sure to fly on calm days. Most of my issues have come on days with wind over 10kph. You will love it!

They generally happen around 2m, be flying along slowly, stop to hover and the drone starts to lower to the ground until either I stop the descent or it brushes the ground and continues fly and or hits tall grass/dandelions and cuts the motors. We don't take it out in winds higher than 12kph but I really do think that plays a factor pushing the drone down. I should really be saying it lowers itself rather than drops, though with a breeze it lowers rather fast lol. 2.1.18 does this as well, not as often and the drone seems to notice sooner and does not hit the ground.... usually.

I will still fly mine with 2.1.18 but our last flight with her drone (x4 batteries) was us flying for a couple minutes then watching it lower to the ground-hit-bounce up and continue flying or hit the grass with a prop. All with outdoor settings on and the outdoor hull. Got some awesome pics of the drone while it was flying. I wonder if I should just downgrade hers to 2.1.18? I hate messing with firmware

Drone over the CN Tower in Toronto.

Whoops, should have been more clear. She is running 2.1.19, I'm on 2.1.18 and hers exhibits the drop of altitude much more. Mine does this as well but does not drop as often. I think both have issues but hers is scary to fly. My "much safer to fly" is just from seeing both in action. Eg.. 1 battery worth of flying hers drops 3 times to the ground, mine usually only does it once-ish. It just seems like once a down draft hits the drone does not respond well to it. Those ultrasonics would know the ground is coming closer and we are not giving any inputs to lower altitude. Anyways, I think Parrot gave us a bad ass toy but really needs to fix this one quick cause I'm addicted to flying it now. Those drops make myself and wife uneasy flying, don't want to wreck it. Has been a sheer pleasure to fly just want to share these bits of information.

P.S. Worst thing that has happened so far have been motor cut outs due to hitting a dandelion, most times it just hits the ground lightly and bounces up. She got ar freeflight 2.0 beta (android) that I think has 2.1.19 update in it, mine was for my IPad2. Run both drone control HD and freeflight 2.0. May be a bit wierd for us because she did run on HTC Desire but now runs on IPad3.

Cheers, happy flying

Look for a USB that is compatible with basically everything(Linux, Mac Os, pc) my first USB stick did not work but I got one that was compatible with all types has worked perfect. I think Parrot should be more specific about USB compatibility requirements. Cheers.

Let's be clear here. Even though the drone is in the air it is still the property of the pilot. Any attempt to do something like this would be illegal, pretty shady stuff your suggesting here. Very very easy to track the phones that would do this. No need to be vindictive because your drone broke. I just hope you get it fixed and have some fun.

Omg, that's so as they add these features they don't have to change the damn box. Get over it, it's new and these features are coming. Enjoy flying it while you wait. Wicked new toy and all people do is whine.
