Pre processing

Hi All
Does anyone know of a good (read as easy to understand) tutorial on Pre-Processing especially display conditioning.
Or can anyone tell me how I make a part Appear/disappear when the flaps are in a certain position? Or even just explain how the ranges 0 - 16383 relate to x number of flap positions/animation steps?
My brain just melted

Oh. I use FSDS v2
