Basics: always check your props!

Checking multirotor propellers for signs of damage or fatigue may be second nature to old-pro's but it's something that even the best of us may be tempted to overlook on occasion.
Just a little basic safety video about the importance of pre-flight checks on multirotor-type RC model aircraft. Because they don't glide, prop inspection and, when necessary, replacement is critical to avoiding accidents that could cause expensive damage or even injure someone.
Although miniquads are very tough, even they can suffer subtle prop-damage that could cause safety issues if flown over people or property. When flying a multirotor of any size, always assume it could flip at any moment without warning, so watch where you fly!
