The last modification was the location of the CG. The instruction manual instructs you to balance the SuperStar 7cm (2 3/4") back from the leading edge of the wing root. However a technical bulletin on Horizon's website corrects this by saying this measurement is to be made at the wing tip. This put the CG right on the back edge of the main wood spar where the leading edge sheeting ends. After balancing the plane at the recommended tip location, I decided to see where that placed the CG at the wing root. I wasn't surprised to find that the recommended CG balanced the plane right in the middle of the main wood spar. 5 1/8" (130mm) was the measurement to this point at the wing root. I included it in this article because balancing the plane close to fuselage was much easier than at the tips
