I agree that the information is harder to find, and will require a fair bit of tweaking. Then again, you might not have to worry so much about getting close, because a lot of the moments will fall naturally out of the geometry (i.e. a longer tail arm will automatically result in a higher Cnbeta for the aircraft as a whole). I'm pretty sure that Roskam's first book has a lot of information on estimating coefficients for different surfaces. DATCOM must also do that before generating the whole-aircraft coefficients. In any case, there's no reason that JSBSim cannot have the best of both worlds -- allow whole-aircraft coefficients or separate surfaces.
