Hi
How do you determine where the CG is of a plane that you may have purchased from someone and do not have the plans for that plane.
I purchased a 48" wingspan FW190 that was 80% complete and am not sure how to determine the cg for this plane.
Is the cg determined for this plane and other planes in the same manner??
Do you do the cg check with a full tank of fuel or an empty tank??

Would appreciate your help.
Thx, Tom

Always Empty.Exception to the rule if fuel tank is at CG and doesn't change the CG when empty or full

CG on a 190 is critical, take your time and get it right.
