The full length stringer below the canopy rail is your flight level point and the wing leading edge is 55 inches aft of the datum point. After you raise the tail to flight attitude drop a plumb bob over the leading edge of the wing and measure the distance on the floor from there to the center of the wheel axles and tail wheel axle. Weight times distance from datum of each wheel equals moments. Divide the total weight of all three wheels into the total moments and that is where your CG is. Stay with-in the 15-31% of MAC range. |
