This is very misleading and poor QC by reporters. The drone shown in the video is a toy. It uses small 8.5mm diameter brushed motors and a geared setup in order to spin that very light prop quite slowly. It is meant to look like a DJI product which has much more powerful motors and stronger propellers.<p>If this was used against something that could carry a gimbal system or an FPV racer, the bird would surely not come away from the encounter uninjured.
I don't know if this is a good idea, after watching videos like this one.<p><a href="http://petapixel.com/2015/12/21/a-dji-camera-drone-chopping-fruit-at-1500fps-shot-with-a-60000-camera/" rel="nofollow">http://petapixel.com/2015/12/21/a-dji-camera-drone-chopping-...</a>
