The Hubsan X4 H107D FPV is a very good entry level into the world of first person view flying. Anyone familiar with the predecessor, such as the H107C know what to expect one, a small agile racer :) But you can adjust the sensitivity as with the predecessor, which allows a small flights in small living spaces. A protective ring for the rotors is what the propellers in the apartment real benefits, for the outdoor air, it is recommended to disassemble the ring, because the attitude improved considerably without the protection. Crash infected colleague quite well off, the material is flexible to some as the 107C, and is already robust. Only drawback is the remote control, rather the power consumption. With standard AA batteries are 5-6 flights in it then the screen goes black and does not transmit a signal FPV more, but still flies. But is positive that the remote control is very good in the hand, despite its size, and the image quality is passable, only the recording quality is not. Also playing the recordings on PC proves to be trickery, a video player you have to download, but a leaflet know it well out, which eliminates the hassle of requests. Also postiv is the S-idea has settled a German instruction, which is not self-evident at the quadrocopters, only a button assignment is not explained, the left button on the amount of exposure control, but after research should be the one stable mode. Is also positive by the display that you have battery voltage and other values directly in mind, also the menu for Senistivität is much more comfortable than the 107C versions, trim settings are stored as the sensitivity, and only when new batteries have to adjust. And at the conclusion of the copter has all functions like others, 3D flips are possible and convinces with good reactions outdoors. But you should outside the copter well to keep in mind a beginner and do not fly only on monitor when the search pass is absemmelt inevitable. Flight time is as short as 7 minutes.
