I have flown my P2V with props chipped worse than yours with no problem. Others on this forum will tell you that is a no-no, and go into long discussions of prop balancing. Maybe, maybe not. It would be mo' betta you replace the chipped and dinged props, but if you don't, then DO check the props carefully before and after each flight to be darn sure they aren't cracked. You don't want the piece to break off during flight and cause your FC40 to crash. Thus just because props are so absolutely essential, you would be best advised to replace damaged ones. I did.
