With all this faboolous input maybe the name needs changed to

Thanks everyone and particularly Verne who not only answered all the
questions but described how to make the changes. Great stuff. Believe I'm
all set to complete the Integral now.<br>

right thrust. The way I did it was to block the fuse up on my table at .5
degrees positive as compared to the stab which I used as my 0 reference
line. Then I glued a little bitty square of 1/32” balsa to the left
side of the nose ring on the face near the outer edge. Then I applied a
very thick, pasty mixture of cabosil and resin to the entire face of the
nose ring and pushed a large, steel angle plate up against it. I wiped
off the excess, and let it cure, using wax paper as a release film
between the angle plate and resin. Since the fuse was sitting at .5
positive and the angle plate was 90 degrees to the table, the end result
was that my nose ring now has .5 down thrust when the fuse is sitting at
0. The little square of 1/32 balsa canted the angle plate .5 degrees to
the right. This all sounds very heavy, but the weight gain was actually
about 4 grams. You may need to think about this for a second, but if your
down thrust is at 0 when the fuse is at .5 positive, then the down thrust
will be at -.5 when the fuse is at 0.<br>

Just curiosity. When you said "add 1/32 right thrust",
means to add to the one is already set at the nose ring? Is
1/32" is at the tip of the prop?<br>
<br>
Thanks,<br><br>

John,<br>
With the stab at 0, make the wing .5 positive, reduce the down thrust to
.5<br>
down, and ADD 1/32 right thrust. I'm currently finishing my third one
and<br>
got it right on the second one. Now I'm just duplicating it. Actually,
the<br>
first one flew great but needed some mixing. With the settings I just
gave<br>
you, it'll track straight forever on either knife edge with no mix.
The<br>
extra right thrust was to eliminate a slight left drift at the top of
tall<br>
verticals. I left the stab at the factory position and called that 0.
Your<br>
wing will actually be slightly negative to that so you'll need to
increase<br>
the incidence to .5. The nose ring has a little over 2 degrees down
so<br>
you'll need to remove 1.5 degrees from that. Can't help on the gear, I
used<br>
Bolly F3A Longs. BTW, set the CG at the LE of the wing tube or just a
little<br>
rearward of that, like 1/8" or so. Hope this helps.<br><br>

Subject: [NSRCA-discussion] Integral Landing gear<br><br>
<br>
The landing gear legs I received with my Integral weigh 6 ounces and are
<br>
very rigid as well. I noticed that when Jason listed the weights of the
<br>
components on RC Universe that the gear legs were listed at 3.2 ounces
<br>
which is a substantial difference.<br>
This will be powered by a YS 170. I haven't checked yet but I intend to
<br>
add adjusters if necessary to achieve stab incidence of 0.0 degrees and
<br>
a wing incidence of +0.5 degrees.<br><br>
I have three questions that I would like to resolve before I get
any <br>
further along.<br><br>
1. Is there a replacement gear that is lighter and in particular more
<br>
flexible? Height of the gear should be about 8 inches.<br>
2. Should the downthrust be reduced from the approximately 2 degrees
<br>
built into the nose ring to about 0.5 degrees down or ?<br>
3. Should the sidethrust be reduced?<br><br>
Would appreciate help from those of you who have already run into these
<br>
problems and found solutions that are working for you.<br><br>
Thanks<br><br>
