Here's another drawing if you want to calculate on it. The grid is 100mm. The CG is shown on the side view at the leading edge of the wing. It has a full flying canard, leading edge slats and flaperons - the last two features couldn't be used because I would run out of elevator to match the additional wing lift. This model was much too heavy (the wing complications and retracts didn't help) and, after a few flights, found its rightful place as a hanger queen.
