I just finished reading this analysis on grid fins.

I know my next project for all these 3" mailer tubes lying around. A simple, motor-deply, high G-motor to baby-H MPR/HPR using grid fins. I can get plastic grids super cheap. I'm thinking I cut a hole in the middle of a 12"x12" grid and epoxy the rocket smack dab in the middle.
I bet the fins make a wicked hissing sound.
Off to the drawing boards!
