<DIV><FONT face=Arial size=2>Incidence meters of all types are generally not
accurate enough for pattern use. You need an accuracy of 0.1 deg. I have
an electronic digital level that will read to 0.1 deg and I only use it for
cross checks. Although the readout is good to 0.1 deg, the overall accuracy
isn't that good. </FONT><FONT face=Arial size=2>If you have a good flat
table...the very <STRONG>best way</STRONG> is to set the fuse on the table and
measure up to the centers of wing/stab LE/TE then with trig calculate the
incidence angle. To do this you need an accurate vertical measurementwith
an accuracy of 1/64" or better. On the Focus I and II the bottom of the
fuselage is zero incidence. Both wing and stab should be set to specifications
provided by Piedmont from this reference.</FONT></DIV>

<DIV><FONT face=Arial size=2>I am currently installing my wing adusters on
my Focus 2 and I am trying to calibrate my Great Planes Incidence Meter. I
placed the meter on a perfectly level table and set it for Zero Degrees. I
decided to rotate the device 180 to see if it would still be level (the
laser was roughly facing north and now is facing south). The
degrees changed positive 1/2 degree. I thought I might have moved the
placement of the laser so I secured everything possible with tape and
rotated it again. Same thing. Does anyone know what might be the
problem???</FONT></DIV>
