As an excercise, here are some FT scale sweet spots, as long as I didn't

make any grade-school math errors, which is always possible: (Abstract 
1g to ~10 m/s^2).

1Thrust Min/Turn	km/"		Genre
1g		.05 (3s)	.05		A		
1g		.167 (10s)	.5		B		
1g		1		~20		C
1g		2.5		~100	D
1g		7.5		~1000	E
1g		~10		~2000	F
1g		17		~5000	G
1g		24 (~25)	10000	H

0.5g		.08(5sec)	~.06		B
0.5g		1.5		~20		C
0.5g		10		~1000	E
0.5g		34(~35) ~10000	H

1/7g		20		~1000	E
1/4g		15		~1000	E
2g		5		~1000	E		

Genres (these are taken from my impressions of the various media YMMV), 
with useful objects for scale:
A = "Atmospheric" Dogfighting: Most Cinema/TV Type fighter combat (WWII 
model?), Babylon 5 = 100" long
B = "Newtonian" Dogfighting:  (Also possibly more like modern 
atmospheric?) Babylon 5 = 10" long (Was it 5 miles or 5 km?), Eros = 
66"x26", Comet nucleii inches to tens of inches across
C = "Cinematic" Cinema/TV scale: Star Wars Capitals (Death Star 
=~Mimas = 20"), Eros = 1.5"x1", Mathilde = 3", Vesta=25"
D = "Hard" Cinema/TV scale: Babylon 5, BSG capitals (Death Star 
=~Ceres = 9")
E = Terrestrial Planet scale: Ceres =~ 1", Earth = ~12",  Jupiter 
atmosphere = "wall" off one side).
F = Large Planet scale: Earth ~ 6" Mars ~3"
G = Planet System scale:Earth = 2.5" Jupiter = 28" Earth-Moon may be on 
opposite ends of a large field (75" apart), though the moon would be 
2/3" or so across
H = SFB/Old Trek scale: Earth ~1-1.5", Earth-Moon=38" , Jupiter=14", 
Galilean satellite orbits at ~40", 63", 105", and 182"from center of 
planet (the sats themselves are all rather less than 1" across), 
Saturn=12", rings extend 1"-82" from "surface", Comet comas tens of 
inches across.

I prefer gaming in the "Terrestrial Planet" scale (and 1g or 
0.5g/thrust), but I can see some interesting scenarios with "Planet 
System" scale, and indeed, most of the others.
