Ive been looking over everyones rockets and rocket pictures, and Ive noticed something:
Some folks put their altimeter vent holes in line with the fins; some put the avionics bay rivets/screws in line with the fins.
I get putting the vent holes 60 degrees out (for a 3 fin rocket) or 90 degrees out (for a 4 fin rocket) from the disturbed air of the fasteners to get them into clear air, but no one has ever explained to me why I want either my fasteners or my holes in line with the fins.
What do you do and why?
