When I am preparing my flights with the fantastic Challenger 650 I don’t know what to write for the gravity center of the plane. It is important for adjusting the takeoff trim. In a video I saw the value of 22 for the CG and I always write 22 for the CG and the plane always gives me 6° up for the trimming.Where can I find the CG value in the plane ? I searched everywhere but I did not found the place to find this value. Can you help me ? Another question : I can turn on the lights for
