Ok, model dimensions are a mere:

12.191 x 5.505 x 4.878

Terrain size is:
horizontal : 6975
vertical : 6510

What I'd like to do is have the terrain equal to about 10x10km. At least 5x5km. (It needs to be big, because I plan on turning this into a seek and destroy demo, where you can play as either the Panzer IV or British Crusader Mk.II out in the desert. Tank guns usually have a range of 2km!This Panzer can hit at almost 2.5km under ideal conditions. :D) So it must be quite large. Then have the tank be properly scaled in the world to reflect that.

Re-read that part of the manual for gravity and scaling. Makes sense to me now. Let me grab a pen and paper and work out some calculations....

EDIT: Well, in the following equation... :

G = (-9.81m/s2)

...what exactly is "m" supposed to be? They say on a normal quant scale, where 1q = 1inch, they derive:

Gravity => (-9.81 * 100 / 2.54cm) = -386

Where is the 100 coming from?
