How damaged is a blade before it’s garbage?

[Drgnfli]

Personally if I had a prop that was even nicked it would get replaced. Actually out of all the years I’ve been flying drones I have never even had to replace any of the props.

I could say that too if it wasn't for an attack by a hawk which cracked a couple props after which I was very lucky to be able to fly my MP home.

I have one that looks exactly the same, a chip and a crack. I replaced only the damaged one since the other side was clean. So far so good.
