Hubsan X4 "Ladybird" micro-drone ($45). It is nearly identical to the X4-C model, except that it is slightly smaller in size, and has a smaller LiPo battery. Hubsan also makes a larger model, the $173 X4-D. I've been crashing them around my apartment for the last few days, so stay tuned for a full review.
My initial thoughts from the 659 crashes I've experienced so far are that these quads are a blast to fly, and are extremely durable. However, the video is lacking, and not really useable at a pro level, but it is fun to watch your near-misses (on microSD cards). I read these things can do flips in expert mode, so I'll try to work it into #QUADthemovie.
