Just curious if anyone just changes props out as preventative maintenance due to time used? I got about 90 to 100 hours on my Mavic Pro with original props, of course no damages whatsoever, never touched anything other that a few blades of grass.
How often do you remove them? That will make a big difference on the life of the prop hub tabs' lifespan.
Other than checking the tabs, you can check the rivets to make sure the props are not too loose. Also if the blades are smooth on both the leading and trailing edges, you might be ok.
This is a little off topic from the original post, but I have found that props will lock on the motor, not lock, or somewhere in between. I am never too careful about checking to make sure they are locked. If a prop doesnt lock on one motor, I try it on a different motor, and if it locks, they are a good match. If a prop wont lock on 2 different motors, it goes into the trash. The tabs might have worn out, and no need to risk a $1000 drone on a $5 prop.
