for the advise...I think I'm on the right track. As for the "spectacular

color=#0000ff size=2>The Aresti has a real good power to weight ratio with
this set up. Plane is under 5-1/2lbs. If I pull power, the nose will start
to slowly drop at the top of the 1/2 reverse cuban 8 as the airspeed
decreases.</FONT></SPAN></DIV>

<DIV><SPAN class=576053620-01052003><FONT face=Arial color=#0000ff size=2>I got
through the up/down thrust test on the trim chart and ran out of time. Seems ok
through this part of trimming. I did note that I may need a little more right
thrust as it requires right rudder after pulling to vertical about 200ft. Didn't
notice a pitching tendency. I'll check it again and pay closer
attention......</FONT></SPAN></DIV>

size=2>Hello Larry,</FONT></SPAN></DIV>
<DIV><SPAN class=126413918-01052003><FONT face=Arial color=#0000ff size=2>You
should not be trying to trim out the pitch behavior with rudder in level
flight, but in the knife edge and/or vertical down. Tail-heaviness makes
planes pull to the belly both there and in level flight with rudder. You just
might be tail-heavy, based on your statement that you have to make the looping
portion of the 1/2 reverse cuban start. You are probably in the very smal
adjstments needed neighborhood. Unless your horsepower is spectacular (it
should with the combo you have) a normal plane will want to start to at least
think of dropping its nose after the 1/2 roll on the 45
up.</FONT></SPAN></DIV>

<DIV><SPAN class=126413918-01052003><FONT face=Arial color=#0000ff
size=2>Check both knife edges and the up and down lines. If three out of four
(it's not a vote) pull to the belly, then you are
tail-heavy.</FONT></SPAN></DIV>

Question<BR><BR></FONT></DIV><!-- Converted from text/rtf format -->
<P><FONT face=Arial size=2>I am sorting out an H9 Aresti 40 that I intend to
start with Sportsman until I get another plane sorted out.</FONT> </P>
<P><FONT face=Arial size=2>CG appears to be very close. It holds a 45 degree
upline straight and needs a touch of elevator to start the pull through the
1/2 Reverse Cuban 8. Inverted flight only requires a touch of down
elevator.</FONT></P>
<P><FONT face=Arial size=2>My tank location was modified from the intended
location and is on CG, to be read, "The front of the fuel tank is about 1/4
inch forward of the leading edge. I have mounted a YS 63 and has unlimited
vertical after 4 tanks of fuel. CG is currently located at 4" back from the
LE per the instructions (aft range). This tank location result in
outstanding ground handling on grass. Zero tendency to nose over, not even
close...</FONT></P>
<P><FONT face=Arial size=2>The problem is in level flight it pitches to the
belly with rudder input. Made for an interesting landing when I corrected
with a touch of rudder for cross wind. </FONT></P>
<P><FONT face=Arial size=2>Is this an incidence problem? I haven't tried a
power off dive yet to check it out due to time. What else could I look
for?</FONT></P>
