OK, I bought one of the monsters. The only thing I have negative to say is that some of the instructions are counter intuitive. I accidentally powered off the controller with the Phantom still idling. After 60 seconds it decided to take off to find home, so I grabbed it and bruised and cut my fingers on the furiously spinning blades. I straight-away bought a set of prop guards to keep that from happening again!
After watching a few youtube videos and re-reading the instructions, I was able to fire that baby up and have 3 fairly short flights (only the first one ended in a crash as I was too near a tree. The next two were to try out the GPS systems, which seems to work flawlessly, even in some wind.
Next, I mounted the camera and took it to a wide open space to get more familiar with the aircraft. It was glorious! Filmed for about 9 minutes before the battery lost power and I had what I would consider a hard-forced landing. No damage at all, however. The camera popped out of it's rubber grommet thingies and not a scratch on it.
Here's a link to my first flight with the camera and first night-flight: https://www.youtube.com/watch?v=wudmRGeQKeg
I was up 80 or 90 feet when it happened and it came down pretty quick. It actually landed about 3 feet from the home point. It just didn't have enough juice to come down as slow as it did before (I am guessing from the added weight of the camera). I got it up to over 100 ft with no issues at all until the battery drained.
Overall, it was a blast! I got up above the treeline and got some pretty decent HD video of the park where I had just played tennis.
I am now officially addicted to these things. I think I am going to have to upgrade to the Phantom 2 Vision+ in the very near future.
Sipping was fast and cheap. Only $18 for overnight delivery! Seems like a well built machine.
I also bought 2 extra batteries with the prop-guards, so I should be able to get 3 flights out of it before having to give up.
I will probably be selling the FC40 as soon as I get the Vision+ in a few weeks.
If you think you might be interested at all in one of these airborne marvels, I suggest starting with the FC40. Not that expensive, and you can always move up.
