<P class=MsoNormal style="MARGIN-LEFT: 0.5in"><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">What he is saying is this:
As the servo arm rotates from 90 degrees, the effective length of the servo
arm gets shorter, meaning that for each incremental degree of rotation of
the servo arm from 90 degrees, you get less incremental movement of the
pushrod. Therefore the control is inherently more sensitive around
neutral than it is at the ends of the servo throw, assuming linearity in the
rest of the system. Expo can be used to counter this natural
tendency.</SPAN></FONT><o:p></o:p></P></DIV>

<DIV>
<P class=MsoNormal style="MARGIN-LEFT: 0.5in"><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">HOWEVER, the effective length of
the surface control horn also gets shorter as the surface moves from neutral,
increasing movement with each incremental movement of the
pushrod. So it is a race between decreasing effectiveness of
the servo output arm vs. increasing effectiveness of the control horn.
Then you get into non-linearity of the aerodynamic surface effectiveness
itself as it moves from neutral, and you can get confused real quick.
You are dealing with several areas of non-linearity, and trying to compromise
between them all.</SPAN></FONT><o:p></o:p></P></DIV>

and some pondering to understand what you said. It doesn't matter what type
arm you use,correct so far? What I take this to mean is as the servo arm
moves the point at which the servo is connected to the driving rod and the
center arm screw is at it's farthest point at 90 degrees to the servo case
(assuming the servo case is 90 degrees to the hinge line) as it moves
forward or backwards the distance between the pivot points decreases
with each degree of rotation. Correct?</SPAN></FONT><o:p></o:p></P></DIV>

Continuing story

T is looking out of the shop door and sees that the weather is just
perfect for some trim flights<BR><?/smaller><?/fontfamily> <BR><?fontfamily><?param Arial><?smaller>So
we pack up the trailer and go for some trim flights. Recalling
the last flights all control throws too sensitive so
I dial in less rates on low and put high rates to what low was
before. Ok time to dial in some Expo on all surfaces, pop up the
screen on the 9303 and dial in 30%. Ok time to fly. Airplane seems
pretty stable now but the controls feel a bit "Twitchy" hmmm no
problem continue the flight land and have a look. Ok maybe I didn't
get enough expo dialed in so add some more. Next flight about the
same but the controls seem a bit more "twicthy" hmmm something's not
right here. Ok times up for flying for today pack up and head home.
On the way home I get to thinking about the last flight and how the
airplane changed the "feel" after I added the expo. Ok I get to
wondering where the heck did I put the book for this new radio, Ok
lets review the book on page A20 is the expo directions, it states
"NOTE: Use only positive percentages unless there is a distinct need
to do otherwise". Hmmmmmm that don't sound right! Turn the
transmitter on and look at the expo I've got dialed into the radio,
*&%^$*&#)(#&%^%)@(_*&_(^# Everything is done
to the NEGATIVE !!!!!! No damn wonder! So "Note to self" today's
lesson is READ THE FRIGGIN BOOK !!!!!!!!!<BR><?/smaller><?/fontfamily> <BR><?fontfamily><?param Arial><?smaller>Ok
while I'm at it lets program a little down elevator trim at
low idle, I wonder what page that is on in the
book.................. "Fade to Black as Timmy T reaches for the
book."<o:p></o:p></SPAN></FONT></P><?/smaller><?/fontfamily>

guess is that he's using a JR radio, because negative exponential is
what you want on a Futaba transmitter to soften the control
response. That's why well-meaning people at the field need to find
out what brand of transmitter the guy being counseled has before
telling him how to change the expo. <BR><BR>I had a similar
situation when I was helping a novice trim out his airplane. After I
flew a trim flight for him, I told him he needed 50 - 60%
exponential on elevator and aileron. I asked him if he knew how to
do that and he said that he did. The airplane was a handful on the
subsequent flight, because he put in the wrong expo!<BR><BR>Ron Van
