I have built and owned plenty of racing and photo drones. Dji is one of the best. There is a big difference in a racing drone that uses esc and motors that take a lot of power to fly at high speeds and for quick maneuverability. They have designed the camera drones to use lower RPM speeds with bigger props to handle the weight and to fly for longer time. A fpv racing drone used to be a huge difference in flight time but that is changing fast. I have went through the Phantom 1,2 3,4 and now have the Inspire 2 for filming and my new favorite fpv racing drone that flies for a substantial long period of time is the new DJI Titan DC5. The flight time has increased dramatically, best fpv racing drone made so far with excellent video quality. Best fpv video transmission without any lag or blips while flying. I would definitely recommend this for anyone that is experienced in flying.
