CG ( Help!)

[quailbird]

Up till now I have been flying delta wings, but I am going to make a straight winged airplane. On the chart I have, that I got off the internet on CG, it shows a swept back wing. How do you find the CG on a stright winged airplane?

If it is a straight wing with constant cord, then the c.g. should be set at 25% of the wing cord - 25% of the way back from the leading edge.

If it is not a constant cord wing, then it gets a little more complicated.

Put "0" where the computation asks for leading edge sweep.
