Crashed Mini 4K Indoors: Propeller Damage Inquiry

Hi everyone. Today, while flying outside, a large door blew inward, pushing my Mini 4K inside the house. It hit another door and fell.

Now, one of the propellers has a raised edge or an uneven spot that I can feel. There’s a slight noise, and I suspect it’s the wind hitting that raised edge. I don’t have the Japanese screwdrivers necessary for repairs.

I’m asking if I need to swap the propeller or if it’s still alright to use. It still flies normally.

You should change all the props.

Why all? They only come with 2 spares.

It’s just best practice. I personally don’t always replace all of them, but if one propeller is damaged, I replace both blades on that rotor to avoid issues.

Just switch them out.

Alright, I will do that.
