So I was just wondering if there is a specific guideline around when to change the Phantom's propellers. Everything I read says to replace them if they get chipped and all that but I was curious if there is an actual suggested replacement time based on how many hours you fly or distance, etc.
No, you only need to change the blades if they are damaged or chipped or even a rough scratch. They are all balanced so the minor scuff can lead to not flying well. You should always examine the blades carefully
