When the BMPC-4K is available later this year (by late "July 2013" or thereabouts), it should be ideal for helicopter/high-vibration shooting because, unlike most CMOS sensor video cameras, its sensor uses a global shutter instead of a rolling shutter.
Global shutter means no rolling shutter "jello", "skew" (vertical lines in moving objects appear slanted), or "flash band" (partial frame exposure) artifacts, and if an aircraft's rotating prop is in a shot, it'll look the way it should, not bent/curved.
The BMPC-4K isn't close enough to shipping yet for there to be sample footage available for it. But the benefits of a global shutter are well known (most CCD cameras have a global shutter).
Other cameras may have their own advantages, such as slightly more dynamic range, or slightly more light sensitivity, or slightly less noise, and so forth. But all things being equal (which they usually never are), global shutter is very desirable for video which contains lots of motion.
However, if you need a camera right away, the BMPC-4K won't be readily available for months, especially if you haven't already placed a pre-order.
