Two things:
- The visual CG point moves in the wrong direction when adding weight. Eg. when I add a pilots weight to my helicopter, the CG visualisation moves to the back of the helicopter.
- I have my datum reference point well in front of the helicopter. CG limits are therefore far in the minus Z range but setup around the empty CG. Something like datum reference at +10, forward limit at -9.5 from datum, aft limit at -10.5. Now it always says CG out of limit.
