Building Smart Drones with ESP8266 and Arduino

Safety of the drone

Always look carefully at your drone after every flight to check whether there is any damage. Inspect the outer shell and the propellers carefully. If you see any damaged component, do not hesitate to change or repair it. Before every flight, check the battery stage and the propellers' condition. Never fly your drone if your props are not firmly connected or motors are not mounted properly. Remove them if there is any dust or dirt on the outer shell of the drone or the gimbal, because not doing so might cause the drone's component to have a hardware failure.
