<DIV><FONT size=2>That is odd Tim. I wonder why JR decided after all these
years to change from a pos. setting to a neg. for a "softer feel".
I'm a firm believer in "If it ain't broke, don't fix
it" </FONT></DIV>
<DIV><FONT size=2>I made the same mistake a few years back when I switched from
a Futaba 7UAP to a JR 8103 and inadvertently put neg. expo in the 8103.
Talk about pucker factor for a few minutes.</FONT><FONT

<DIV><FONT face=Arial size=2>That's 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.</FONT></DIV>

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 !!!!!!!!!<?/smaller><?/fontfamily><BR> <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."<?/smaller><?/fontfamily><BR></BLOCKQUOTE><BR>My 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
