One option would be a Navio2 [1] flight controller which runs the PX4 or Ardupilot flight stack on a realtime linux kernel on an rpi. You'd then need to put that on an airframe (a F450 or one of it's many clones is a solid choice if you intend to use this thing outdoors). You'll also need all the ancillaries (receiver, batteries, charger, rc transmitter) although you'll need those anyway if you plan to fly outdoors in a safe manner. Alternatively, if you want a ready to go solution which is good for indoor and limited outdoor use, the Parrot ARDrone [2] runs linux, has two cameras and has aftermarket firmware available from both Ardupilot and Paparazzi projects. Be aware that if you intend to use your drone for 'work' or commerce you should check your local air regulator (FAA/CAA/CASA etc) to see whether you require any permissions or qualifications to legally operate. 1: https://emlid.com/navio/ https://emlid.com/navio/ 2: https://www.parrot.com/uk/drones/parrot-ardrone-20-gps-edition#parrot-ar-drone-20-gps-edition https://www.parrot.com/uk/drones/parrot-ardrone-20-gps-editi...
