Hello,
I always get a 'overloaded' or 'outside the centre of gravitiy' with this data (weight in kg):

EmptyWeight="509.300000" EmptyArmLon="0.44" EmptyArmLat="0.00" Envelope="238.00,558.000000,320.00,750.000000,392.00,750.000000,292.00,558.000000">
    <FuelLoadingPoint Name="Fuel" LeverArm="0.33" LeverArmLat="0.00" DefaultValue="109.60" Capacity="120.00" />
    <LoadingPoint Name="Pilot" LeverArm="0.58" LeverArmLat="0.00" DefaultValue="80.00" />
    <LoadingPoint Name="Front Passenger" LeverArm="0.58" LeverArmLat="0.00" DefaultValue="0.00" />
    <LoadingPoint Name="Baggage" LeverArm="1.30" LeverArmLat="0.00" DefaultValue="10.00" />

But the numbers should be correct - could anybody help please?

Hi George,
Thanks for your answer, but with your data I didn't see a graph.

I just took the data from the manual - and with this numbers the envelope looks like the picture in the manual:
