pilot / passenger station position Hello Mark
I read Johns reply and agree with him. The rake of the seat will change where the center of the weight is located (You could call it the CG of a sitting body mass). For example a big headed person with a large heavy torso and stick skinny legs could easily move over 100 to 150 pounds aft by several inches by raking the seat back This may seem silly and may not work, but if you were to build a simple seat bottom and back with the same rake angle as the aircraft and then place a section of pipe under it. Next sit on the seat as you would in the aircraft and move the pipe to a location under the seat where you balance. From this you should be able to see just where on your aircraft that same balance spot would be and that is your location.
