You should be able to run an 11.1V OOTB.
Just don't be stupid and you'll have no problems. Whenever I've seen crap happen it's usually because people are holding down the trigger for extended periods of time or not taking care of their crap. Doesn't mean that it's a perfect system but I've seen very few lemons from VFC. However, I have seen the stock pistons (the clear ones) shred themselves.
IMO if you run it at like 380-395 FPS and do short bursts with an 11.1 and don't throw it around or try to use it as a crow bar it should last you.
