Just a question that keeps me bothering. Or bothering is a big word maybe, lets just say I am wondering... How long can it keep going? And by "it" I mean the Phantom (2) and all its parts/electronics. For example: the brushless motors and the brushless ESC's. What typical life to expect? I know brushless motors can run for quite some time, but coming from the RC car and boating world, I can say that ESC's can be time bombs (although they are taxed a whole lot harder in trucks/boats). You wouldn't dare to think about motor/ESC failure during a flight, so then the next interesting question becomes: at what moment would one be deciding to replace motor/ESC with a new one? How about props? Do they have the eternal life even when there's never been a crash? At what % of monitored overall battery life (as checked in PC Assistant) would you have to stop using an intelligent battery? And say there's only the slightest sign of puffing, would you replace a pack immediately? All in all what I mean with "how long can it keep going". Motors and ESC's is what I wonder about most.
