Paul , one of the first things I did was change out the wheels. You will be able to save over a pound of weight. I wish I had recorded where my CG wound up but I know it was forward of where the book called for, which is odd for me, cause I have most of mine set back from the recommended on other planes. I do remember that at 4 13/16" it was not hazardous to fly, just felt tail heavy.
Had a lot of fun with it and a G23 mounted up front. It will get brought out flown again one day.
