Well I got my PicooZ past few weeks and the least we can say is that it is not so easy to handle. In addition, the polystyrene makes up the hull of the camera is rather fragile. One of the legs was so split, I had the mend with a bit of sctoch.

Or the burden is pretty good at the drums. New models have recently emerged and are sold in a box duo and allow for real dogfights. When a helicopter is shot, it unscrews in the air before resuming a normal position. On the video, it sounds very fun but in reality I'm not sure of the result.
