Adding a note. The readme speaks of.

Aircraft.cfg file changes: ========================== 1. Under the [WEIGHT_AND_BALANCE] section, ensure the following: reference_datum_position     =  0, 0, 0         empty_weight_CG_position     =  9, 0, 0

Now the default value is -9, 0, 0, so you could delete that '-' when it comes to the instructions. However, this seems to mix up the stab trim recommendation (and the flight model) a bit and e.g. returns trim values like 15.4.

By this, I'd say that sticking to the default value with the -9 seems appropriate. I could be misunderstanding something here, but only the default value ensured proper trim recommendations for me so far.
