Hello --

When do you change props?  Do they 'wear out'? Assuming there isn't any physical damage, is there any rationale to change them?

TIA,

Eventually they'll get junk on them - you'd be amazed at the bugs the props hit, honestly.  You can clean all that off, but if it whacks the grass or twigs, you might actually knick them - just do an inspection and if you have knicks in the props, replace them.  I fly with the same set until I get a scrape or knick.  Oh and from some extensive comparison test I've seen, the original DJI props are the absolute best for efficiency, thrust, and economy.

Not really, there will be no damage unless you crash the drone

Correct! Also efficiency  depends on motors, i'll post an article about it very soon
