<DIV><FONT face=Arial size=2>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.</FONT></DIV>

<DIV><FONT face=Arial size=2>The 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.</FONT></DIV>
