I read this post 3 times from start to finish and it looks like the CG is 5 3/4" to 6" from the leading edge at the fuselage. I am going to be using a Brillelli 46GT in mine and I will more than likely need to add about 1 1/2lbs of lead to the engine box to get her to Balance. It seems no matter what you do the plane will weigh in around 20lbs when balanced[:@] Still I know Fishdeath had a Thor 45 in his with 2 lbs of added weight up frony and it flys great Here is a link to his video.
