I've done just around 60 flights since last September when I bought my X-Star with the original props, I don't see a reason to change them any time soon. Sent from my XT1650 using Tapatalk
Yeah I would replace if they get scratched or nicked, kinda throws them out of balance. I haven't had that problem yet with my XSP but I have noticed on some of my smaller quads that if the get nicked or scratched they don't fly right till I throw on a new set of props
