Flying a few days ago and the wind was gusting at around 15 mph. On the last flight of the day my P3P had a landing tip over.
There was no damage to the quad, but I noticed to owf the blades got dinged up a bit. Here's a picture of the blades, you can see the small chips, I
was wondering if these are still okay to fly with. I have several other sets, but if they're still okay why change them out..

Opinions?

Hi!

Mhm...I know that carbon fibres propellers are more expensive than normal one, but why risk for whole aircraft?

Did you do auto land? Land and do CSC to shut off motors?

Hold down left stick for 3 seconds?      In the future I would suggest doing a hand catch when it's windy, make sure to practice it several times on a day with zero wind to get the hang of it, once you master that you'll never have to worry about it tipping over. I personally hand catch it every time. If the land is un level it's also possible to do a hand launch but that's a little more tricky.

The blades will probably be out of balance now and will cause a vibration in the aircraft.  
That puts more strain on the motors themselves, and on the whole P3.
I would not take the risk.

It was pretty windy, but nothing I hadn't flown many times before. I was landing manually & the quad had just touched down. And at the same time I'm shutting down, it tipped backwards. In fact, the motors shut down a second or two after it fell backwards....

If you have a chip in the leading edge of a prop, it'll act as a stress raiser & could potentially cause the blade to fail eventually.  A risk vs. cost analysis would suggest you bin the damaged ones.

Good Call !

First, props are cheap.
Next, I stopped landing on the ground after three such tipovers and have posted a couple of them at the moment they went over.  I hand catch now and have no problems at all.  

Change then, not worth the risk. I don't think there will be any issues just not worth the risk.

Mine tipped over when it is new by landing it manually with no wind on a flat surface.  2 props got chipped which can throw the props out of balance and you can get unwanted vibration. I always autoland now even on a windy day and never had a problem since.

For those that don't really understand how a tipover happens.  Here's a video of my buddy take his first flight with my P3P.  It was a little ugly - as expected - but he did OK for a first time.  Notice I'm watching the controls to make sure he's only on the left command stick and slowly descending.  It you got to 6 minutes, you'll see clearly what happened [the part before that is uneventful].
Ask me again why I hand catch ------

Any noticeable prop damage is bad.  Any Nicks in them they are shot.   I inspect my props after each flight.  After 10 hours of flight I'll replace them no matter what.  Carbon fibers I would say 15 hours.   Still waiting on CF for the p4.   

I know I'm chucking props that will still be fine with service life and no damage but no chance in risking.   Few dollars for plastic. 15-20 for cf?  Very worth playing it safe.

In my opinion, it looks like he wouldn't commit to the land or fully press the throttle all the way down, instead it just hovered a tiny bit off the ground and eventually the wind tipped it over.

So do you like the Carbon fiber props? Noticeable differences?
