I had an accident today.  Mini 2 flipped over an obstruction and props were damaged.  I didn't realize there was damage, because it kept flying, maintaining position, etc.
When I landed, I saw big chunks out of two props.  I have switched them out, but it is nice to know that the mini 2 can take a licking and keep on ticking.

Just like John Cameron Swayze said (...take a licking and keep on ticking.) ;-)

When I was first learning a year ago I crashed s few times. I have used a emery board a few  times thawing the burs off. I didn’t try to remove the chips.  I’m still flying with the same blades. Actually they don't look to bad. Nothing like the pictures above.

Woah cool to hear that it was robust enough to get through it, not bad.

Thats certainly gives some reassurance how sturdy the little drone is.   

Good to know!

It is good that it was able to limp back. But please be aware that flying with damaged blades stresses the motors and could cause them to overheat or fail. Not that you were flying with broken blades on purpose, but it is good to know this.

Wow! Glad the outcome wasn't any worse.
