This is a basic question that has probably already been covered in a dozen or so other threads, but I could not find the info by searching. I am building my first HPR rocket, a Mad Cow Big Fizz, and the instructions say that the rail button should rotate freely after it is mounted. So here is the question: does the rail button *need* to rotate freely (i.e., would a fixed rail button prevent the proper operation of the button/rail interface) or is this just advice to prevent the button from being compressed/distorted too much?
I read the info on railbuttons.com, and it sounds like a common way to mount rail buttons is to epoxy the button onto the tube (and that would certainly prevent the button from rotating freely).
Forgive me for such a basic question, but I am new to HPR.
