yeah! Sorry 'bout the omission, Pete.</FONT></SPAN></DIV>

<DIV><SPAN class=414265816-02022005><FONT face=Arial color=#0000ff size=2>I
added two washers (about 0.040" ) between the hardwood beams and the front posts
on the soft mount.</FONT></SPAN></DIV>
<DIV><SPAN class=414265816-02022005><FONT face=Arial color=#0000ff size=2>That
works out to another degree of down thrust, compared to
stock.</FONT></SPAN></DIV>
<DIV><SPAN class=414265816-02022005><FONT face=Arial color=#0000ff size=2>The
right thrust is at 3 degrees ( 3/4" difference in tailpost distances across the
15" prop) because any more made the plane dog-track.</FONT></SPAN></DIV>
<DIV><SPAN class=414265816-02022005><FONT face=Arial color=#0000ff size=2>Some
right rudder trim was added, and it's a good compromise.</FONT></SPAN></DIV>
<DIV><SPAN class=414265816-02022005><FONT face=Arial color=#0000ff size=2>I am
anxious to try the throttle/rudder couple: planes with real big chins tend to
suffer from the "there is no correct amount of right thrust"
syndrome.</FONT></SPAN></DIV>
<DIV><SPAN class=414265816-02022005><FONT face=Arial color=#0000ff size=2>I am
still cutting back on control throws ... a whole bunch. I think that the high
rate elevator will end up at 22 degrees, and the ailerons are at about 15
and are still faster than needed.</FONT></SPAN></DIV>
<DIV><SPAN class=414265816-02022005><FONT face=Arial color=#0000ff size=2>The
rudder is at 35 degrees.</FONT></SPAN></DIV>

<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks for the info. It will be a big help as I
finish up my Excelleron. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I do have a couple questions though:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>What right and down thrust do you have dialed
in?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Are your incidence measurements using the stab at
"0" and then measuring the wing?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Did you use the manufacturers suggested throws on
the control surfaces?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>BTW - Thanks for all the info.</FONT></DIV>

<DIV><SPAN class=507153114-02022005><FONT face=Arial color=#0000ff size=2>Hi
Nat, and Hi Terry,</FONT></SPAN></DIV>
<DIV><SPAN class=507153114-02022005><FONT face=Arial color=#0000ff size=2>My
Excelleron weighs spot on 9 pounds with the Magnum 120 AR and
15-10.</FONT></SPAN></DIV>
<DIV><SPAN class=507153114-02022005><FONT face=Arial color=#0000ff
size=2>The CG is at 7-1/16" and the total incidence (with the 1/16"
positive I added) is 3/32" as compared to the stab.</FONT></SPAN></DIV>
<DIV><SPAN class=507153114-02022005><FONT face=Arial color=#0000ff
size=2>The plane carried UP elevator trim, until I added the incidence, and
the CG had to be about 7-1/4" back to almost get rid of the
trim.</FONT></SPAN></DIV>
<DIV><SPAN class=507153114-02022005><FONT face=Arial color=#0000ff size=2>I
didn't like how the airplane flew, there: it was just marginally tail-heavy
and the "lock" in wind suffered.</FONT></SPAN></DIV>
<DIV><SPAN class=507153114-02022005><FONT face=Arial color=#0000ff
size=2>The plane also hinted at climbing out of a 45 climb or
dive.</FONT></SPAN></DIV>
<DIV><SPAN class=507153114-02022005><FONT face=Arial color=#0000ff
size=2>The snaps are lovely, and high rate elevator will still cause the
plane to "bury" in the snap, so it ain't nose-heavy.</FONT></SPAN></DIV>
<DIV><SPAN class=507153114-02022005><FONT face=Arial color=#0000ff
size=2>The vertical UP line is straight, and the DOWN line only pulls to the
canopy after a full 4 Mississippi count.</FONT></SPAN></DIV>
<DIV><SPAN class=507153114-02022005><FONT face=Arial color=#0000ff
size=2>That's plenty good for anything in the schedule.</FONT></SPAN></DIV>
<DIV><SPAN class=507153114-02022005><FONT face=Arial color=#0000ff
size=2>The knife edges are dead straight, and there are no electronics used.
That was part of my review criteria: entry-level with non-fancy
radios.</FONT></SPAN></DIV>
<DIV><SPAN class=507153114-02022005><FONT face=Arial color=#0000ff
size=2>The plane knife edge loops beautifully, and when you wail on the
rudder in the last 1/4 loop, it does proverse roll a small
bit,</FONT></SPAN></DIV>
<DIV><SPAN class=507153114-02022005><FONT face=Arial color=#0000ff
size=2>but this doesn't show at the kind of rudder throw necessary for point
rolls.</FONT></SPAN></DIV>
<DIV><SPAN class=507153114-02022005><FONT face=Arial color=#0000ff size=2>I
think this is the easiest knife edge looping ship I've had my hands
on.</FONT></SPAN></DIV>
<DIV><SPAN class=507153114-02022005><FONT face=Arial color=#0000ff size=2>I
am contemplating pushing the CG even farther forward, to see if I can get it
to trim properly.</FONT></SPAN></DIV>
<DIV><SPAN class=507153114-02022005><FONT face=Arial color=#0000ff size=2>I
think a beginner will benefit from a freight train ... I mean slightly
nose-heavy plane.</FONT></SPAN></DIV>
