I am designing a pure delta wing turbine jet from scratch. Is there a rule of thumb for determining the CG on a delta wing, or can I use the geometric method used for a swept wing? Each wing panel has a 27" chord at the root, a 5" chord at the tip and a 16" span for 54 degrees of sweep. I need to know the proper CG location so I can lay out the gear and other equipment. Any help would be appreciated. Terry

Rule of thumb is 15 to 20 % Built a foamy Convair Pogo and set the CG at 20 % . Being sceptical, I built a 9 in. glider with the same planform and the CG came out at 20 %
