CG Calculator is a totally free and portable program for estimating the center of gravity of simple wings.........
can calculate the CG, with some accuracy, for simple wing shapes.No
installing required, you
just copy the exe file to a friends PC and it will run. Enter the
wing dimensions acording to the diagram, then press calulate.
is generally enough to give you a good balanced model that will fly
stably... Planes without a tail should have the "CENTER OF MASS"
(balance point) a few millimeters forward of the CG.
the CG of an entire model is preferable but not always that easy. Its
much more work to measure the whole plane and you only get a small
advantage (in most cases).
In the near future, this APP will be updated to include whole model and compound wings, calculations. So call back soon..
