couldn't find much 'hard' information so a lot of this fdm is

includes some weapons so I'm allocating 8000lb to his and

subtracting it from the max wieght.

I got a figure of 24000lb for the fuel load from a web site.

this seems rather high to me but until I can get a better

figure it'll have to do.
