much tension, but the fact that the loop on the adjuster is too small....
It is very important that the spring be able to pivot slightly. If the
loop is too tall, the HD springs tend to twist the adjuster just
slightly.... If it is not corrected, the repetitive motion will eventually
cause the adjuster to fail.</FONT></DIV>

<DIV><FONT face=Arial>I will have to second the thingy on the stiffer
springs. I too was guilty of erroneous stick movement during rolls and
other areas. Stiff springs helped as I was often guilty of un noticed
elevator stick move while rolling. </FONT></DIV>
<DIV><FONT face=Arial> I did have an experience here last month where the
pin stop on my aileron gimble broke from too stiff of spring tension.
Kinda had me worried a little while during a roll the thing kept rolling till
I noticed there was NO tension on my left aileron stick.</FONT></DIV>

<DIV>
<DIV>I'm a newbie also and won't advise on what to do about trimming for
this problem. But my experience with trimming issues was fairly
humbling.</DIV></DIV>
<DIV> </DIV>
<DIV>After struggling for many weeks with suggestions about trimming on my
plane, I did finally go to a contest and asked a seasoned pilot to check it
out. After putting it through a few masters maneuvers that looked impressive
to me, he landed and said it just needed a couple of clicks on the
aileron.</DIV>
<DIV> </DIV>
<DIV>After a full season in Sportsman, I look back and reflected that most
of the problems were not trimming of the plane. I was coupling control
inputs every-time I moved a stick. Looked like I was having trimming
problems, and it was repeatable. I could actually screw it up the same way
every time.</DIV>
<DIV> </DIV>
<DIV>I focused on stick movement at every contest and replaced the factory
springs with some stiffer springs from one of the Chicago folks, Bobby
Satalino. Jim Hubbard did the surgery replacing the springs after the
contest and I have been flying much better since.</DIV>
<DIV> </DIV>
<DIV>Every contest I went to had great folks very willing to help out. Allot
of advise on flying maneuvers that allowed me to see improvements at each
contest I entered.</DIV>
<DIV> </DIV>
<DIV>My only recommendation is to follow the advise of others in this
thread and get a seasoned pilot to help out.</DIV>
<DIV> </DIV>
<DIV>Good Luck...</DIV>

<DIV><FONT face=Arial size=2>Courtesy of Buddy, I've placed (with his
permission) his summary of the "trimming" issues. Probably many of
you share my view that his summary was one of the most on-target, concise
statements I've read about trimming in a VERY long time, if ever!!!

color=#8000ff size=2 FAMILY="SANSSERIF" PTSIZE="9">Paul<BR>I am no
aerodynamics expert, but I have learned some basic's over the years that
work for me.<BR>1. The wing must have a positive angle of attack to
create lift.<BR>2. the stabilizer and elevators steer the pitch attitude
of the airplane resulting in more or less lift.<BR>3. Balance can change
the angle of attack which will change the pitch attitude.<BR>4.
Aileron's up or down will change the pitch attitude .<BR>5. Up or down
thrust will change the pitch attitude.<BR>Therefore:<BR>A. Increasing
the positive wing incidence will cause the airplane to climb, which will
require down trim to achieve level flight.<BR>B. Likewise adding tail
weight will cause the airplane to climb and require down trim to achieve
level flight.<BR>C. Added weight does not alter the vertical down line
BUT elevator trim added to maintain level flight because of the added
weight will effect the down line. Tail weight will require down trim
which will steer the airplane more to the belly in a down line, and
added nose weight will require up trim which will steer the airplane to
the canopy.<BR>D. In the vertical up line elevator trim and the engine
thrust line will effect the vertical and/or yaw direction
<BR>All of the above will effect the knife edge flight of the
model.<BR>Combinations of adjustments to any or all of the above trim
items done at the same time will leave you confused and
frustrated.<BR>Most models will require some mixing to achieve near
perfect lines in all flight attitudes in order to minimize / eliminate
control inputs by the pilot to maintain a perfect course.<BR>I have yet
to see the perfect airplane should such an animal exist, but I keep
looking and building since I truly believe that nothing is
impossible.<BR>When trimming an airplane make a written log of every
change no matter how small so you don't have to start over when changes
are not correct.<BR>Buddy</FONT>
