<DIV><FONT face=Arial size=2>The finite number is in reference to some other
surface on the plane, or to a defined line </FONT></DIV>
<DIV><FONT face=Arial size=2>on the plane. </FONT><FONT face=Arial
size=2>For instance, on a Focus 1, the forward part of the bottom of fuse
is </FONT></DIV>
<DIV><FONT face=Arial size=2>considered zero </FONT><FONT face=Arial
size=2>degrees per the plans. </FONT><FONT face=Arial size=2>The wing is
shown at </FONT><FONT face=Arial size=2>zero degrees, and stab </FONT></DIV>
<DIV><FONT face=Arial size=2>at negative 1/4 degree.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Put fuse on a table, and shim the fuse to get
zero degrees on forward bottom of fuse</FONT></DIV>
<DIV><FONT face=Arial size=2>if it is </FONT><FONT face=Arial size=2>a Focus
1 (which makes things real easy). Or shim fuse to get zero at
</FONT></DIV>
<DIV><FONT face=Arial size=2>whatever defined line is specified </FONT><FONT
face=Arial size=2>for the </FONT><FONT face=Arial size=2>particluar
plane.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>((Side note- this is the point where meter
bias, if any, is compensated for. </FONT></DIV>
<DIV><FONT face=Arial size=2>You set </FONT><FONT face=Arial size=2>a
zero line with the specific meter, and then use same meter to set the
</FONT></DIV>
<DIV><FONT face=Arial size=2>other angles. </FONT><FONT face=Arial
size=2>Working from the same side of the meter isn't necessary, if you
</FONT></DIV>
<DIV><FONT face=Arial size=2>swap 180 and verify </FONT><FONT face=Arial
size=2>that there is no difference.))</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Then reading meter from </FONT><FONT face=Arial
size=2>same side, adjust to get the prescribed angle (zero for Focus
1)</FONT></DIV>
<DIV><FONT face=Arial size=2>on both wing panels. Also adjust stab
to get the precscribed angle, (neg 1/4 for Focus 1)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Something to keep in mind - all these meter
measurements are of course dependent on exactly</FONT></DIV>
<DIV><FONT face=Arial size=2>where the meter mounting system is attached to the
surface, and assumes the surface is perfectly</FONT></DIV>
<DIV><FONT face=Arial size=2>uniform. On solid (foam/balsa) surfaces
that were built straight to start with, and sanded with only long</FONT></DIV>
<DIV><FONT face=Arial size=2>sanding bars, they are likely pretty
good. Maybe not perfect? I take angle measurements at
several</FONT></DIV>
<DIV><FONT face=Arial size=2>places along the surfaces to verify
consistency. (All from same side of meter, since I know
my</FONT></DIV>
<DIV><FONT face=Arial size=2>meter is about 1/2 degree different side to
side) Another item, check that the mechanical </FONT></DIV>
<DIV><FONT face=Arial size=2>attachments to the surfaces result in the same
angle readings, as the mechanical reference </FONT></DIV>
<DIV><FONT face=Arial size=2>points </FONT><FONT face=Arial size=2>you may use
to establish zero at the planes reference line.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Hope that helps,</FONT></DIV>
