Sounds like your original question was about C.G. What I have learned, & I do with all my planes, is set the C.G. where the instructions tell you to. Fly the plane, trim it for straight & level. Roll it inverted & see how much down elevator it takes to fly level. If the nose drops, nose heavy. If opposite, tail heavy. Most will be nose heavy. l If so, move weight back. Get it so it takes a tad of down elevator to fly level inverted. I have done this with all my planes & they are a blast to fly. Set the C.G. where the plane wants it. The only adverse effect to doing this is they tend to float when landing. I correct this by setting a couple of clicks of down elevator trim on the base leg of my approach. This allows me to fly it in to the landing.
Hope this helps
