A. The law is a bit murky here in terms of licenses and registering of drones, and as such your best bet is to check local regulations and brush up on the latest requirements from the FAA. In general, you won’t need a license if you’re flying a drone recreationally and the drone weighs under 55 pounds. Anything heavier than that and you might need to register it. If you’re trying to earn money with your drone, you’ll need to be licensed. The FAA is more than willing to fine or even jail those who violate drone rules, so this is definitely not an area you should ignore.
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.
