<DIV><FONT size=2>For all you mathematical intellectuals, I dont have an
incidence meter that I feel too good about, so here is my question: I have a
datum line drawn on the side of a fuse, a line parallel to the datum through
the wing tube, and the distance from the center of the wing tube to the
leading edge is 7". The plans call for 3/4 degree positive incidence. What
is the measurement from the parallel line (to datum) to the center line of
the root?</FONT></DIV></BLOCKQUOTE></BLOCKQUOTE></BODY></HTML>
