it?</FONT></DIV>

<DIV><FONT face=Arial size=2>Also take a measurement of the stab incidence,
or as well as you can. It should be around zero. Also look at the alignment of
the elevator to the stab itself and make sure you're not carrying any large
amount of trim, because that can make things wierd. </FONT></DIV>

<DIV><FONT face=Arial size=2>I have had more than a few people tell me it trims
out better with a hair of positive incidence in the stab, in fact I carried some

Question</DIV>

<DIV>
<P>I have a trimming question for you guys. A couple of days ago I was
checking the amount of control throws on my first Black Magic V2 so that when
I set up my backup plane I'd have a ballpark setting to start with. The
ailerons and rudder were about what I expected, but the elevator was 5 degrees
of up throw and 10 degrees of down throw. The wing incidence is set per the
plans and the CG is at the leading edge of the wing tube with the wings off.
The airplane has the same feel when I add up or down elevator. Inverted flight
requires a little down elevator. Basically the airplane feels just right.
<BR><BR>I'm wondering what you guys think I should do to correct the
differential in up and down elevator throw? I was thinking that I may have a
little too much positive incidence in the stab. Any suggestions? <BR><BR>Rick
</P></DIV>
