Is it possible to change the camera?

I do think that this is a depends answer. Depends if you have the Drone, and can actually get the physical dimensions to replace it with cameras that are of comparable dimensions in order to not alter the flight characteristics of the Drone. Then it depends on the firmware/software that the drone uses, it may be specific for the cameras, and may not accept anything else. The only way to make sure that you can, is by doing it....let us know if you are going to so we can all learn something. Good Luck :-)
