I am getting ready to cut foam for a full flying stab. I will be using a blend of the HT14 (4.5"root) and an HT12 (3.75") at the tip. Bell crank pivot and actuating pin hole is 1.5" C/L.
Is there a formula for figuring out the optimal pivot point of the bell crank position? I am thinking that the pivot point should be positioned at some distance that makes the top and bottom surfaces balanced when actuated. Has anyone else used Mark Drela's HT# tail airfoils(http://www.charlesriverrc.org/articles/drelaairfoils/markdrela_tail airfoils.htm) for a full flying stab? How were your results?
