Does anyone have any idea how long a phantom 3 (in my case a P3A) is expected to last.. Assume props are changed when needed, no crashes etc. I am thinking maybe in terms of expected mileage, or hours flown before motors start to fail, or motor bearings need maintenance etc? I appreciate the battery might need to be replaced, but it's the airframe expected duration I am interested in.. By the way, I have the old motors if that makes a difference.. Does anyone have any stats yet?
