1. A method for determining the center of gravity (CG) of a remote controlled aircraft, the method comprising:
a) providing a CG measurement device including a base member having a slotted track defined therein and a plurality of support platforms mounted on the base member, wherein each support platform of the plurality of support platforms is slidably positionable along the slotted track;
b) positioning a respective digital CG sensor on each support platform, wherein each respective digital CG sensor includes a mass scale to measure a mass of the aircraft at each respective digital CG sensor;
c) placing a respective wheel of the aircraft on each respective digital CG sensor;
d) measuring:
i) a first distance between front and rear wheels of the aircraft;
ii) a second distance from main wheels of the aircraft and a leading edge of each wing, wherein the second distance is subtracted from a manufacturer-provided CG location to yield a third distance; and
e) calculating a CG location of the aircraft using each mass measurement recorded by each respective digital CG sensor, the first distance and the third distance.
