I have the PB2. Love it. Very powerful drone for a smaller drone. Brushless motors, has GPS AND Glonass, has several autonomous features like waypoints and points of interest, etc. Great return to home, extremely accurate. With the Skycontroller, can get up to 2km distance. Just an amazing drone for a smaller drone, great technology inside. Camera is it's weakest point, but still takes good video and pics, they did a firmware update to improve the video/camera quality. My guess is they will improve the camera quality to near 4k on their next Bebop.
