<p class=MsoNormal style='margin-left:.5in'><font size=2 color=black
face=Arial><span style='font-size:10.0pt;font-family:Arial;color:black'>An easy
way to measure thrust line relative to wing is to bend an L shaped
piece out of aluminum strap to attach to the motor. The plane does
not need to be level to measure. Use a Sullivan and/or a Robart
meter to measure the wing incidence, then "sit" on top of the prop
bracket and measure the down thrust.</span></font><font color=black><span

<p class=MsoNormal style='margin-left:.5in'><font size=2 color=black

horizontal leg on the prop bracket only needs to be 4 to 6" long
for the meter to sit on. The meter can be held in place with a rubber
band if needed.</span></font><font color=black><span style='color:black;
