Nice drone.
Bought the SP510 as a Christmas gift for my daughter. I got it up in the air then and it was great! The GPS works good and is easy to use for beginners. The back to home feature is great for inexperienced flyers. It was too cold then, and now that it has warmed up and wanting to use it I am struggling with getting it calibrated. But customer service is good and responsive. They sent me a video to watch to try and figure out what i am doing wrong. If that doesn't help they said i could upload a video of what i am going so they can see first hand what the issue is. I don't doubt i will get it working, just wanted to mention how good the customer service is. This is a good little drone but does require some time in learning how to use it. Update: with the help of the video, I was able to get the drone in the air and took my first picture from above!
