OK, aircraft weight and balance exercise. My pipe is 27.5” long from the header to the tip of the pipe and weighs 7 ounces. The pipe spans the desired CG point on the aircraft. I installed the header and pipe and marked the aircraft CG point on the pipe and then removed the pipe from the aircraft. I then found the balance point on the pipe and header and discovered that it is 2” forward of the desired aircraft CG I marked on the pipe. So the pipe is exerting two inches more of its weight ahead of the aircraft CG. 7 ounces divided by 27.5” = .2545 ounces per inch. The pipe has 2” of its weight ahead of the desired aircraft GC resulting in .5090 ounces of weight ahead of the aircraft CG. Does that sound correct?
