anything to do with it, only the lengths of the control arms relative to each

<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>BTW, I tend to agree with Jim Oddino, our servo
arms/wheels are rarely the same size as our control surface arms. In fact,
with our use we need only 10-15 degrees (30 degrees in both directions) throws
and therefore we need smaller servo arms to get close the 100% range of motion
of the servo. If the servo arm and control surface arm are the same length
and the entire range of the servo is used then we would have throws equal to the
degrees that the servo can turn (I'm guessing about 70 degrees).</FONT></DIV>

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>

few readings 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>

I'm writing an article for the KF right now that talks about Expo and
how to use it. When to use it. And the effects of it. Sometimes a
reverse expo (faster response) at center can be of benefit. We have
played with this in snaps and found that it has some promise...Lots of
regular expo on the ailerons and rudder and reverse expo on the

whole point in the story Ron, I ASSUMED I was right and didn't NEED
to RTFB and could have screwed up big time. I've been flying JR
radios for years but always a PCM10 of some sort, this 9303 is a new
radio for me. What I did was get in a hurry, I wanted to fly
and trim this airplane and didn't do what I should have done first.
I hope my not so comical errors will help someone else from making
the same mistake I did.</SPAN></FONT><o:p></o:p></P></DIV>

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

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
