<DIV><FONT face=Arial size=2>Vince, if you decrease the wing incidence you
will need more up elevater mix for the knife edges, not less. Let us all know
how it turns out.

<P class=MsoNormal style="MARGIN: 0in 0in 0pt">Yesterday, June 3, 2005 I
flew my Abbra the first time.<SPAN style="mso-spacerun: yes">
</SPAN>For those interested in the equipment please see Bob Pastorello web
page.<SPAN style="mso-spacerun: yes"> </SPAN>The version that I flew
is the glow version using OS160 engine.<SPAN
style="mso-spacerun: yes"> </SPAN>Final weight is 9 lb 14 oz.<SPAN
style="mso-spacerun: yes"> </SPAN>I know that I could reduce the
weight a little more by using lighter wheels and smaller receiver.<SPAN
style="mso-spacerun: yes"> </SPAN>It is OK for me since this plane is
my first 2 m class plane less than 10 pounds.</P>

style="mso-bidi-font-weight: normal">First Fly impressions:</B><SPAN
style="mso-spacerun: yes"> </SPAN>Clearly the most constant speed
plane that I ever flown.<SPAN style="mso-spacerun: yes"> </SPAN>I can
fly closer to show a better presentation.<SPAN
style="mso-spacerun: yes"> </SPAN>It is going to take some time for me
to get along but definitively I like the change.<SPAN
style="mso-spacerun: yes"> </SPAN>Please understand that this is my
first wide body plane.<SPAN style="mso-spacerun: yes"> </SPAN>For
those flying already wide body planes probably won’t be a big change.<SPAN
style="mso-spacerun: yes"> </SPAN>The down lines are a pleasure to
watch.<SPAN style="mso-spacerun: yes"> </SPAN>I felt as a pilot that I
have more time to make corrections.<SPAN style="mso-spacerun: yes">
</SPAN>Slow and snaps rolls are fantastic. Landing is a pleasure.<SPAN
style="mso-spacerun: yes">&n! bsp; </SPAN>Not sure yet about spins since
I did it once only.<SPAN style="mso-spacerun: yes"> </SPAN>I really
didn’t like the break.<SPAN style="mso-spacerun: yes"> </SPAN>I think
I need a little more up elevator since I lost some travel amount after the
elevator trimming.<SPAN style="mso-spacerun: yes"> </SPAN></P>
<P class=MsoNormal style="MARGIN: 0in 0in 0pt"><o:p> </o:p></P>
<P class=MsoNormal style="MARGIN: 0in 0in 0pt"><B
style="mso-bidi-font-weight: normal">First Trimming Impressions:<SPAN
style="mso-spacerun: yes"> </SPAN></B>As soon I took off I knew that I
need down trim.<SPAN style="mso-spacerun: yes"> </SPAN>I got fixed and
finish with 28 bits of down trim in my JR 10 X radio.<SPAN
style="mso-spacerun: yes"> </SPAN>Also I finished with 4 bits of left
trim.<SPAN style="mso-spacerun: yes"> </SPAN>Ailerons and elevators
were set up for 10 degrees travel.<SPAN style="mso-spacerun: yes">
</SPAN>After the first landing, what a landing it was a 10 using the old
rules, I checked the elevators and found that one half was a little more up
than the other half.<SPAN style="mso-spacerun: yes"> </SPAN>Also, I
found the same problem in the right aileron that was a little more up. When
I say a little is almost difficult to see at naked eye.<SPAN
style="mso-spacerun: yes"> </SPAN>Definitively the plane was tellin! g
me that I need a better mechanic.<SPAN style="mso-spacerun: yes">
</SPAN>This was clearly mechanic error (me!!).<SPAN
style="mso-spacerun: yes"> </SPAN>I checked the CG and the plane looks
fine now.<SPAN style="mso-spacerun: yes"> </SPAN>If you ask me where
it is the CG now “I will say I don’t know”.<SPAN
style="mso-spacerun: yes"> </SPAN>I am one of those guys that check
the CG in the air.<SPAN style="mso-spacerun: yes"> </SPAN>I put the
battery behind the firewall so I knew that I was a little nose heavy.<SPAN
style="mso-spacerun: yes"> </SPAN>The plane requires a little pressure
when flying inverted.<SPAN style="mso-spacerun: yes"> </SPAN>Right now
I need more time to finish CG adjustments.<SPAN
style="mso-spacerun: yes"> </SPAN>My taste is a little tail heavy so I
will start to move the battery but I want to correct the positive incidence
first.<SPAN style="mso-spacerun: yes"> </SPAN>I will check the actual
locatio! n for those that want to have the information.<SPAN
style="mso-spaceru: yes"> </SPAN>The rudder was set to about 30
degrees.<SPAN style="mso-spacerun: yes"> </SPAN>I think is OK.<SPAN
style="mso-spacerun: yes"> </SPAN>I did the master schedule one
time.<SPAN style="mso-spacerun: yes"> </SPAN>I feel now that I am OK
for travel.<SPAN style="mso-spacerun: yes"> </SPAN>Probably, I will
need to get a little more up for the spin but I did it only once
yesterday.<SPAN style="mso-spacerun: yes"> </SPAN>In the second fly, I
did finish with 8 bits of down elevator.<SPAN
style="mso-spacerun: yes"> </SPAN>I know that my plane was set up for
0.75 degrees positive incidence.<SPAN style="mso-spacerun: yes">
</SPAN>I also know that you can order the plane now using 0, 0.25, 0.50 and
adjustable that you will need to install.<SPAN
style="mso-spacerun: yes"> </SPAN>It is clear to me that 0.75 is too
high and probably I will go 0.25 in my next Abbra to reduce the down
elevator trim.<SPAN style="mso-spacerun: "> </SPAN>The positive
incidence and the elevator trim causes that the plane requires rudder with
up elevator mix to hold knife edge in both sides.<SPAN
style="mso-spacerun: yes"> </SPAN>In this regard, it is clear the
plane requires opposite aileron also.<SPAN style="mso-spacerun: yes">
</SPAN>This is not a surprise to me since I never had a pattern plane that
didn’t require any mixing during knife edge.<SPAN
style="mso-spacerun: yes"> </SPAN>I still tweaking with rudder mixing
with elevator and rudder.<SPAN style="mso-spacerun: yes"> </SPAN>The
final information will come in the future.<SPAN
style="mso-spacerun: yes"> </SPAN>My next step in trimming the plane
is to try to reduce the positive incidence to 0.25 degrees to minimize the
mixing and the down elevator amounts.<SPAN style="mso-spacerun: yes">
</SPAN>Also, I will increase to 12 degrees the up elevator to improve the
break on spins.<SPAN style="mso-spacerun: yes"> ! </SPAN>On lateral
balance I don’t think that I have to adjust.<SPAN st
yle="mso-spacerun: yes"> </SPAN>The plane tracks very well in loops
but I need to check a little more.</P>
<P class=MsoNormal style="MARGIN: 0in 0in 0pt"><o:p> </o:p></P>
<P class=MsoNormal style="MARGIN: 0in 0in 0pt">Tomorrow, I will have a judge
calibration section.<SPAN style="mso-spacerun: yes"> </SPAN>The judges
will tell me if my impression of fantastic landings, snaps and slow rolls
are realistic. </P>
