Wild Beat:

What kind of plane are you working on?? Top wing, sholder or low wing and how big is it. on my last kit i used a triangle to get the vert stab straight up and fabric tape measures to get the position correct. Are you working on an ARF or a Kit? Most ARF's have it setup in some form or fashion to get the vert fin right and some instructions in the manual to help with setting up the wing and horx stab lined up correct. I've set up a few so let me know if I can help further.
