small dents in the propellers

[Bruchpilot]

Hello friends,

after I kept getting small pressure marks on the propellers, even with the greatest care (see photo 1), I was able to determine the probable cause.
In my opinion it is because the engines stop abruptly when landing and then the propellers press against the web of the other propeller due to the centrifugal forces (see photo 2).
I fear that the propellers could tear at this pressure point / dent during the flight.
Do you also have the problem and / or some other explanation?

Thanks and regards
