Andrew,

The Blade image looks like the best setup I've seen but I look forward to your test results and images. Good luck with the test. My rudders are old hand made wooden blades and it would probably cost more in postage costs to AHPC than the ruddes are worth !! <img src="http://www.catsailor.com/forums/images/graemlins/tongue.gif" alt="" />
