Carbon fiber drones have been created

Landing and flying drones can sometimes be a tricky business, and occasionally the end of the drone is destroyed in the process if the pilot is not careful, or the environment is hampered by gusts of wind or unexpected obstacles. Now a super-strong personal drone has been created that uses a carbon fiber frame to provide an ultra-high-strength bumper called a carbon fiber drone.

Carbon Fiber UAV is also equipped with a long-distance Bluetooth controller that connects to a companion application on your smartphone, enabling you to control the flight and record the video captured by the UAV on-board camera. The carbon fiber drone is also the world's first carbon fiber personal drone, controlled by Bluetooth and has a built-in camera.

Gate Valves are called "full-flow" Valves; there's a direct unobstructed path for flow right through the middle of the valve. A wedge-shaped brass gate is lowered into a machined slot to close the valve. They should either be completely open or completely closed. Water flowing through a partially open gate valve wears away the metal and causes the valve to fail over time.
