Information about the AAF PIPER J-3 Cub  

This is an update of the 1946 Piper J-3 Cub previously uploaded to the
CIS:Flight Simulator Forum.  It incorporates a new REF-SIM with 
improved visibility, better flight characteristics and the flaps and flap 
sound, (if you are using the SGA upgrade), have been disabled. Additionally,
the wheels have been improved and some dihedral added to the wings.

Certainly a classic  aircraft, this AAF model is an effort to capture the 
Piper J-3 Cub of 1946.  At least that it looks more like a J-3 than 
anything I've seen to date.  I've retained the classic Piper Cub yellow 
with the black stripe on the side of the fuselage.

Some liberties were taken with the horsepower of the reference SIM
to improve the climb rate and cruise.  I have found that it cruises
nicely at about 2000 RPM with 8 presses of the "7" key on the 
numerical keypad ("Flypal" trim setting of -2048).

My special thanks go to Rick Lee, John Kelley, Charles Gulick and the 
many others who have been so complementary, made such fine comments 
and who have provided the suggestions and many of the solutions for 
the improvements to be found in this new version.

I hope you enjoy this effort and would appreciate your comments.
