Aside from inspecting for cracks and other damage before flying and replacing if necessary, is there a suggested interval for blade replacement, like after X hours of flight time? Seems like the stress over time would take it's toll uniformly. Just curious, thanks!

Hi, you might be better off posting in the products section of this forum. That is way more active.

I do a pre-flight check prior to every flight.  I make sure there's no cracks, chips, warping, etc.  If I see anything wrong, I change them.  I always change all of them when I do it.  Props are cheap.

They used to quote a time on the blades but thats not mention for the new drones,  I have 2200+km on orginal Mini 3 blades and they look like new,   If you check pre flight and start getting RPM messages then its time to change as they are deforming.

Hello there urushi. Good day and thank you for reaching out. Just a reminder that before each flight, it is necessary to check your DJI Drone's propellers for cracks, wear, warp, corrosion, and damages. If any of these conditions are present, the said propellers should be replaced. Damaged propellers can lead to unwanted incident when flying your DJI Drone. Thank you and fly safe always.
