1Eye, could you explain how you found that 27% is best? I've read that the neutral point (assuming a symmetric airfoil) is typically at 25% of MAC. I ask because I'm considering a flying stab for a future project. Thanks
I went back and double-checked my last example (an old Top Gun F-15 with tailerons only) and reverified: the stabs (tailerons) were pivoted/balanced at 25% MAC. I'm sorry about the error in my original post; hopefully HarryC will forgive me. [X(] Good luck with your project.
