How to inspect propellers for fatigue?

[Bunraku]

Hi

Is there a way to check your props for any sign of stress or fatigue?

Thanks

Nicks, dents, chips, bends.
On the underside, you want to look at the three locking nubs that hold the props to the motors. look for stress cracks, just something that doesn't look like a new prop. I always check the amount of "lay", hold the motor bell, and check the "play" on the prop., you can have a very small amount of movement, but again, if it feels more than a new prop, change it.
