Hello Folks, I have a new pair of Masterscrew props for my Mavic Pro and noticed after a few flights that there are some nicks on the propeller blades. (see photo) Not sure how they got there, but I'm very conscious of the possibility of a prop failure from nicks in the propeller. The Mastercsrew plastic material seems softer to me than the original DJI blades. Do my concerns seem unwarranted at this point or can I use a bit of sandpaper to smoothen out the nicks?
