Meet the Katana Racing Drone: a high-speed drone with a video feed, allowing you to race and see all the action. It features foldable arms, a crash-resistant carbon fiber arm, and a slim structure. You can optionally use first-person-view goggles and a HD camera with it.
Katana flies for up to 10 minutes on a full battery. It has 5″ propellers. The above video provides more information on it.
