<FONT FACE="Arial"><FONT SIZE=-1>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 class="MsoNormal" style="MARGIN: 0in 0in 0pt"><B>First Fly impressions:<SPAN
style="mso-spacerun: yes"></B> </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 class="MsoNormal" style="MARGIN: 0in 0in 0pt"><B>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 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.
