tip shape for stabilators

[Peter Lert <plert@csn.net>]

        After trying all sorts of fancy tricks to ease the (admittedly 
minor) task of plotting out the airfoil shape to cut out the tip of the 
horizontal stab (including an inconclusive bout with AutoCad), the light 
suddenly dawned:

        Just stand the _tip_ end of TP1 on a sheet of paper and trace 
around it.  Cut out the resulting template, and you can use it on top and 
bottom of both horizontals.
