Hi all, these are the current settings I have.
I have replaced the cheetah for now.

Handling.cfg
CHEETAH 	1400.0 2.0 4.5 1.2 0.0 0.0 -0.3 -1 1.1 0.84 0.53 5 250.0 33.0 R P 11.1 0.52 0 30.0 3.0 0.13 0.4 0.7 95000 0.34 -0.12 0.5 8181 0 1

Default.ide
105, 	cheetah, 	cheetah, 	car, 	CHEETAH, 	CHEETAH, 		executive, 	10, 	7,	0,	089, 0.85

At this point I have not yet textured it, so there is no .txd file.
all that should be in this .zip is the F355.dff and Readme.txt


please do not further distribute this version.

Thanks for testing this for me.
