I was just wondering if anyone has used the 1/4" thick board for fins?
I'm not sure of the proper name for the stuff, but during a school project my wife was unhappy with the dents that occured and purchased another board to complete the school project. Left me with lots of foam board on hand.
I've used a piece to make a fin jig for my V-2, but I was thinking that if you glued another layer of, say poster board card stock over both side and around the ends after shaping, wouldn't that make a good light weight fin?
Now, take in concideration this would be only for the upper end of LPR's. Maybe something in the lower end of the 29mm engines in a normally bottom heavy rocket that would require nose weight using light ply or balsa fins.
Just curious if anyone has used this board in this application, and what to expect as I plan to try it at least once to investigate it's potential.
