This little thing makes a lot of fun and can be extremely precise control, video transmission works Indoor sufficiently well rumzufliegen around the room, there she goes about 50m meters in the knee (I on a 200qx tested), but as far as you can with the little copter eh not fly because of the (required) visual contact is then no longer possible). A dot I pull off, because the battery really is not very long hold out, but good 4 minute are loose inside. I would also want a successor at about this size, with a small battery and Brushlessmotörchen 2s, but just as he is, he's all right and some Crashes coped without problems.
