A flipped tip is basically just less curve than what you think of as a recurve. The tips are bent forward using whatever your preferred method of bending is, whether it be dry heat, or steam, or laminated in. I prefer steam bending. Static recurve, simply means the curves are not bending at all. Some recurves have a little bend to them in the curve. That's my take on it. I'm sure some others will chime in. There's plenty of build a longs in the how to section, do a search there and you'll see some examples of various ways to do it.
