Depends on what you are asking of them, which is going to be judged by the motors and battery. Check to see if your motors have a chart showing testing of different prop/battery combos. I would say this would be okay, but not optimal, for a 5" 4S mini quad. That's what I fly, and I rarely see it go above 100A total using a 4.6 prop. If you have OSD you can add the current draw to your screen, provided you're FPV of course.
