When to replace props?

[Chris0275]

My Phantom 2 has had a few bumps and close calls with the ground and trees, the prop blades are slightly nicked up, at what point should they be swapped out for new ones?

nicks and chips and dents can cause vibrations which in turn can shake things inside the phantom. If you cause a soldering point to vibrate apart, you might find yourself posting a flyaway thread.
