Just got a chance to get back to this thread.. Wow, I didn't know I'd stir something up.

Thank you Matt for taking the time to run your tests and share such great info with all of us. Even with the limited input data, I think you have shown us that there is some benificial info in the results.

I like the replies regarding trailing edge. I never considered it's affects, or knew there were different schools of thought on it's design. That made me take a look at the PC-9's stab again ( it's elevator's chord is slightly tapered, but finishes in a flat trailing edge ) and a closer inspection of the whole kit in general. The more I look, the more I realize just how many subtle things I am oblivious to, or take for granted.

Cool stuff!

Bill
