Thanks to Bill Leaming for the pointer to Aaron Swindle's cub sound;
and thanks to everyone else for the links to Aeronca addins, here
is our updated 12 steps to adding an Aeronca Champion to FS2002.
---------------------Bob Bonda------------------

DOZEN STEPS TO ADD A CITABRIA or AERONCA AIRPLANE INTO MSFS2002:

1. Note the three main flight simulator add-on download sites:
http://www.avsim.com
http://www.flightsim.com
http://www.simviation.com

Pick one, e.g., simviation; then read their instructions, e.g.:
http://www.simviation.com/acinstall.htm

2. View the Microsoft Flight Simulator 2002 aircraft folder:
C:\Program Files\Microsoft Games\Fs2002\aircraft
Note installed aircraft & four sub-folders for each aircraft:
model, panel, sound, Texture

3. Create a new directory for flight-simulator downloads, e.g.:
C:\downloads\fs2002\citabria_7eca\
C:\downloads\fs2002\aeronca_champion\

4. Search for both desired airplanes on the chosen web site:
http://www.simviation.com/search.html

Note: I failed to find "Citabria" planes in any of these searches.
So I searched for "Aeronca Champion" instead.

The following Aeronca FS2002 link was chosen:
http://www.simviation.com/fs2002props31.htm

Which contained this summary:
"FS2002 1946 Aeronca 7AC Champion
This FSDSv2 project includes moving parts including
rolling wheels, transparent textures (not reflective)
and a pilot figure. A panel based on a photo is included.
By Paul Clawson (464K).

Download this file:
ftp://63.217.28.218/1props/Champv2.zip

Into the newly created download directory:
C:\downloads\fs2002\aeronca_champion\Champv2.zip

5. Extract that compressed zip archive to a temporary location:
FROM:
C:\downloads\fs2002\aeronca_champion\Champv2.zip
TO:
C:\Temp\unzip\fs2002\aeronca_champion\*.*

6. As always, read the fine instructions:
C:\Temp\unzip\fs2002\aeronca_champion\Readme.txt

7. Copy this Aeronica folder into the FS2002 "aircraft" folder:
FROM:
C:\Temp\unzip\fs2002\aeronca_champion\Aeronca Champion
TO:
C:\Program Files\Microsoft Games\Fs2002\
aircraft\Aeronca Champion\

8. Copy the Aeronca "gauges" files (not the folder!):
FROM:
C:\Temp\unzip\fs2002\aeronca_champion\gauges\*.*
TO:
C:\Program Files\Microsoft Games\Fs2002\GAUGES\*.*

9. Search Google for "Aaron Swindle's cub sound cub2x2sn.zip":
http://www.google.com

Search for (verbatim, with the quotes):
"Aaron Swindle" & "cub sound"

This located a dozen hits (each a complete package), e.g.:
http://www.simviation.com/fs2002props48.htm

Add a StittsPlayboy directory to your download location:
C:\Program Files\Microsoft Games\Fs2002\
downloads\StittsPlayboy\

10. Download the FS2002 Stits Playboy SA3A zip file into
that newly created downloads directory:
ftp://63.217.28.218/1props/StittsPlayboy.zip

Extract the 76 files in the zip into a temporary location.
C:\Temp\unzip\Stitts Playboy\

11. Add the Aaron Swindle cub sounds to your Aeronca sound directory:

Save the existing 28 byte "Sound.cfg" Cessna 182 alias (just in case):
FROM:
C:\Program Files\Microsoft Games\Fs2002\
aircraft\Aeronca Champion\sound\Sound.cfg
TO:
C:\Program Files\Microsoft Games\Fs2002\
aircraft\Aeronca Champion\sound\Copy of Sound.cfg

Copy the Aaron Swindle cub sounds to the Aeronca sound directory:
FROM:
C:\Temp\unzip\Stitts Playboy\sound\*.*
TO:
C:\Program Files\Microsoft Games\Fs2002\
aircraft\Aeronca Champion\sound\*.*

12. Fly your new Aeronca 7AC tailwheel airplane on MS FS2002!
