The most recent variant, the cx10c, is another small improvement over the other two. Again, it only adds one feature, but this time its a little bit more substantial, this time, they’ve added a camera. With a micro sd card you can watch videos of your flights from the perspective of the drone. It may not be a great camera, its not even a good camera, the footage is mediocre and would never compare even slightly to a high end multirotor, but for the price ($25) and the size (roughly the same as before) its amazing that it includes one.
Many manufacturers mount cameras inside the body of the drone. This is acceptable for casual photography, but if you want more professional results, consider adding an external camera mount, or gimbal. Gimbals allow you to place your video or still camera in front of the drone body, away from the vibrating motor and rotors. Gimbals can swivel and pivot, providing you with additional control over your imagery.
