<DIV><FONT face=Arial size=2>As for the Abbra, well, I started back at 0 with
Brians suggestion when I started this. I am now at zero on thrust (just in the
last few flights) .7 on the wing, and 0 on the stab. I moved my batteries
back a little tonight as it had little effect on the pull to the belly
anyway (not sure why), and I felt it was flying too nose heavy and I
really liked the way it was flying. </FONT></DIV>
<DIV>But then I had more motor problems.. Out of motors now so not sure what

and still pulls to the canopy in downlines. I went a turn and a half
more of positive in the wings and changed the thrust to zero (The thrust I
am going to put back to 0.5) the day before the contest.. The mix
remained the same, and it didn't help my downlines. But it did neutralize
my ele trims from the up it had in it.

heavy than where everyone else has it, matter of fact, it's hard to slow
it down to land, and it bounces on the gear which it never has before..
Now if I'm correct, my problems show me I need more positive in my wings
and a more forward cg according to the triangulation. But if I do that, it
will make my stabs go more negative (or down ele trim), which yes, will
help my downlines, but won't it make it pull worse to the gear in knife? I
already have 1/8 up ele mixed in it in knife. Granted, with an even more
forward cg, that should help with the pull to the gear. Am I thinking
correct here? <o:p></o:p></SPAN></FONT></DIV></DIV>

0.6 and it was 0.4. Clearly, the effect of all this was to reduce
the mixing. I am around 6% all around which is less than 0.5
degree movement of control surfaces. That is not that bad.
The best cg position I have seen is between 0.6 to 1" in front of the
front edge of the wing tube. The Abbra tail heavy tracks really
bad. I did that test yesterday moving the

next time and I will let you know. I am traveling this
week so hopefully weather permitting I will try to fly next

TL relative to the belly pan floor. In this way we can

left it last, the Abbra got a little more up thrust (1 washer) and a
turn and a half more postive incidence for now as a test. It feels a
little nose heavy now. Very bouncy on the gear on landing which it has
never been before moving the cg. But the uplines and 45's looked good
and felt good. Still has almost the same mixes in knife though.
Downlines still pull to canopy. The ele now has neutral trim though..

since I was carrying a little up<BR>elevator, so I took 1/2 turn
out of adjuster which should being it close<BR>to 0<BR>- this
pretty much sealed it<BR>- uplines are as before,! very ! very cl
ose<BR>- no KE mix - even in the KE loop at high deflections its
really, really<BR>good<BR>- took another 1% out of my downline mix
(I am at 2%, started at 5%)<BR>- 45 ups inverted are really good,
just a slight arc over the top<BR>- 45 down upright is finally
straight.<BR><BR>I need to spend some more time on it to really
get a good feel, but I<BR>think the downthrust was causing a lot
of problems to this plane. I have<BR>never had it in all
aspects of flight this close yet. I am anxious to
get<BR>more time on it and see if the changes really stick.
Unfortunately on<BR>Sunday this plane is going to a buddy
but I plan on incorporating all<BR>these changes on the new
Twister which is why I wanted to get it figured<BR>out now

The big problem I cannot resolve is this, a 45 deg down<BR>>
