Trying to determine the proper placement of the main gear on my original design (taildragger). An EAA publication, and most others that I have read, state to draw a line through the thrust axis, place the plane in level flight attitude and determine the CG. From this CG, draw a line 15 degrees forward and where this line intersects the ground, that's where the wheels should touch. This is fine except no article I have read mentions which CG they are using. ( empty weight CG, gross wt CG, ect ). And if the plane were to have a ,say, 5 inch CG flight range, where along that 5 inches would you begin to draw the 15 degree line. To make matters worse, I ran into another article that says not to use the thrust axis, but at the planes vertical CG, which complicates matters . Suggestions? Thanks
