With optical flow and dual camera, DM IN107S is much more powerful and functional than the old version. With optical flow the drone will hover much more stable and the optical flow camera can also be used to take photo and record video, to get a unique downward view, and both cameras are 2.0MP and super clear. It also has a function of 3D flip, G-sensor, point flight, headless mode, one-key take off/landing, and auto return etc. Just take it home and have a wonderful flying experience! The phone is not included.
