A CG question. I am assembling my new UCD 46. I am about to install the Saito 82. The book calls for the face of the spinner back plate to be 5" in front of the firewall. Can some of you experienced folks predict where my CG will be if I follow those specs? I realize that the original spec for the CG was at 4 3/4" and that now the spec is 4" - 6" Since I am not an experienced 3D pilot, I am thinking that I want my CG to be closer to the front for my maiden. I will listen to any comments that you may have, but I think I would like to start at about 4 1/2" or 4 3/4" Since engine placement is the biggest adjustable thing I can do. So should I put the engine at 5" as the book suggests? Any comments greatly appreciated. Jim Tucker
