eCalc - wingDesigner - calculate center of gravity (CG)
wingDesigner4

The wingDesigner4 of eCalc.ch visualizes your four panel wing design and evaluates the center of gravity (CG).
 
It has been found both experimentally and theoretically that, if the aerodynamic  force is applied at a location of 25% of the Mean Aerodynamic Cord (MAC), the magnitude of the aerodynamic moment remains nearly constant even when the angle of attack changes. This location is called the wing's Aerodynamic Centre AC.
eCalc - get your drive right

It is of crucial importance that the Flying Wing Centre of Gravity (CG) is located at the right point, so that a stable and controllable flight can be achieved.
 
The optimal CG must be evaluated in flight. For safety start evaluation always with a static margin of 5...15% for a good longitudinal stability and use resulting CG. Never ever exceed AC on first flight!
