Default RE: Sterling Spitfire

Thanks Dick,
I now understand the differences in chord line and zero lift angle for asymetrical airfoils.
If I understand this correctly, the difference for the fuse reference line to zero lift angle would be about 4.2 degrees (assuming minus 2 for 0 lift angle)? Therefore making the stab then about .3 positive? Thence; your suggestion to reduce the stab angle to about 3.5, or minus .7? Or; leave it where it is for high speed operation over the original's ability?
I hope I have this right as it took me 20 minutes with the TV off to think it out!!!
Thanks again, Dick.
