Great for beginners
Advantages: This is a really nice looking quadcopter. Best of all, it has a decent and workable altitude hold. It's easy to fly - very stable. I've tried it outdoors in a very light breeze and it was just fine. It's a lot of fun to fly. Compared to the original X5C the props are much, much quieter. It seems to fly a little smoother too.
Limitations: It's a little slower than some quads and it doesn't seem to respond to the throttle immediately. I'm guessing that's to do with altitude hold. I have to experiment, but I think you need to give enough extra throttle so that it doesn't try to counteract an altitude change!
