So I'm building a 38mm rocket to be powered by a G64 and F12 AT reloads. I've got done designing it and find it....well...blah. It's a simple 3FNC rocket. So to spice things up I decided I would find the center of each fin (they are trapezoids) and then drill a 3/4" hole right through the fin. I thought it would be interesting and give it a new look. Anyone know how this will effect stability? I'm thinking I will have to find the square inches of then fin before hole, then the square inches of the hole. I just add the two together and arrive at a fin shape that has the square inches of the fin plus the square inches of the hole, so when I drill the hole out I'm left with the original square inches.
