<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 Putte<BR></BLOCKQUOTE></BODY></HTML>
