RE: Are My Calculations Right???
You mean you're trying to find the Mean Aerodynamic Chord of that wing. Finding the CG for a model involves not only the wing but also the fuselage tail arm length and the stabilizer area. There are links to some online calculators in the sticky resource threads at the top of the forum listings. Check them out. They tell you where to place the CG in terms of distance back from the leading edge of the wing at the root.
