I don't follow the "more deflection" line of thought. Do you mean "more drag" ? I've always had a gut feeling the holes created more drag if the Navy used them. My advise is : on the heavier KR's, 700 pound range, go with a 9 inch by the width of the fuselage, put holes in it, and get it to deflect to as near 90 degrees as possible. http://myplace.frontier.com/~flesner/19.jpg Say fellow, that's some nice looking holes you have there...................
